**Requirements**:
|
||
* [Docker](https://docs.docker.com/get-docker/)
|
||
|
||
## Overview
|
||
Contains Docker images for the different components of CKAN Cloud and a Docker compose environment (based on [ckan](https://github.com/ckan/ckan)) for development and testing Open Data portals.
|
||
|
||
> [!IMPORTANT]
|
||
>This is a **custom installation of Docker Compose** with specific extensions for spatial data and [GeoDCAT-AP](https://github.com/SEMICeu/GeoDCAT-AP)/[INSPIRE](https://github.com/INSPIRE-MIF/technical-guidelines) metadata [profiles](https://en.wikipedia.org/wiki/Geospatial_metadata). For official installations, please have a look: [CKAN documentation: Installation](https://docs.ckan.org/en/latest/maintaining/installing/index.html).
|
||
|
||
|
||
|
||
|
||
Available components:
|
||
* CKAN custom multi-stage build with spatial capabilities from [ckan-docker-spatial](https://github.com/mjanez/ckan-docker-spatial)[^1], an image used as a base and built from the official CKAN repo. The following versions of CKAN are available:
|
||
|
||
| CKAN Version | Type | Docker tag | Notes |
|
||
| --- | --- | --- | --- |
|
||
| 2.9.8 | custom image | `ghcr.io/mjanez/ckan-spatial:ckan-2.9.8` | Stable version with CKAN 2.9.8 |
|
||
| 2.9.9 | custom image | `ghcr.io/mjanez/ckan-docker:ckan-2.9.9` | Stable version with CKAN 2.9.9 |
|
||
| 2.9.10 | custom image | `ghcr.io/mjanez/ckan-docker:ckan-2.9.10` | Stable version with CKAN 2.9.10 |
|
||
| 2.9.11 | custom image | `ghcr.io/mjanez/ckan-docker:ckan-2.9.11` | Stable version with CKAN 2.9.11 |
|
||
| 2.9.11 | latest custom image | `ghcr.io/mjanez/ckan-docker:master` | Latest `ckan-docker` image. |
|
||
|
||
The non-CKAN images are as follows:
|
||
* PostgreSQL: [Custom image](/postgresql/Dockerfile) based on official PostgreSQL image. Database files are stored in a named volume.
|
||
* Solr: [Custom image](/solr/Dockerfile.spatial) based on official CKAN [pre-configured Solr image](https://github.com/ckan/ckan-solr). The index data is stored in a named volume and has a custom spatial schema upgrades. [^2]
|
||
* Redis: Standard Redis image
|
||
* NGINX: Latest stable nginx image that includes SSL and Non-SSL endpoints.
|
||
* ckan-pycsw: [Custom image](/ckan-pycsw/Dockerfile) based on [pycsw CKAN harvester ISO19139](https://github.com/mjanez/ckan-pycsw) for INSPIRE Metadata CSW Endpoint.
|
||
|
||
Optional HTTP Endpoint ([`docker-compose.apache.yml`](/docker-compose.apache.yml)):
|
||
* `docker-compose.apache.yml`:
|
||
* Apache HTTP Server: [Custom image](/apache/Dockerfile) based on official latest stable httpd image. Configured to serve multiple routes for the [ckan-pycsw](#ckan-pycsw) CSW endpoint (`{CKAN_SITE_URL}/csw`) and CKAN (`{CKAN_SITE_URL}/catalog`). Only HTTP.

|
||
|
||
## Environment: docker
|
||
### docker compose *vs* docker-compose
|
||
All Docker Compose commands in this README will use the V2 version of Compose ie: `docker compose`. The older version (V1) used the `docker-compose` command. Please see [Docker Compose](https://docs.docker.com/compose/compose-v2/) for
|
||
more information.
|
||
|
||
### Upgrade docker-engine
|
||
To upgrade Docker Engine, first run sudo `apt-get update`, then follow the [installation instructions](https://docs.docker.com/engine/install/debian/#install-using-the-repository), choosing the new version you want to install.
|
||
|
||
To verify a successful Docker installation, run `docker run hello-world` and `docker version`. These commands should output
|
||
versions for client and server.
|
||

## Install (build and run) CKAN plus dependencies
|
||
### Base mode
|
||
Use this if you are a maintainer and will not be making code changes to CKAN or to CKAN extensions.
|
||
|
||
1. Clone project
|
||
```shell
|
||
cd /path/to/my/project
|
||
git clone https://github.com/mjanez/ckan-docker.git
|
||
```
|
||
|
||
2. Copy the `.env.example` template (or use another from [`/samples/`](/samples/)) and modify the resulting `.env` to suit your needs.
|
||
|
||
```shell
|
||
cp .env.example .env
|
||
```
|
||
|
||
- **NGINX & CKAN/ckan-pycsw endpoints**: Modifiy the variables about the site URL or locations (`CKAN_SITE_URL` `CKAN_URL`, `PYCSW_URL`, `CKANEXT__DCAT__BASE_URI`, `PROXY_SERVER_NAME`, `PROXY_CKAN_LOCATION`, `PROXY_PYCSW_LOCATION`, etc.).
|
||
|
||
- **Apache HTTP Server**: Replace the [`.env`](/.env) with the [`/samples/.env.apache.example`](/samples/.env.apache.example) and modify the variables as needed.
|
||
|
||
> [!NOTE]
|
||
> Please note that when accessing CKAN directly (via a browser) ie: not going through Apache/NGINX you will need to make sure you have "ckan" set up to be an alias to localhost in the local hosts file. Either that or you will need to change the `.env` entry for `CKAN_SITE_URL`
|
||
|
||
> [!WARNING]
|
||
> Using the default values on the `.env` file will get you a working CKAN instance. There is a sysadmin user created by default with the values defined in `CKAN_SYSADMIN_NAME` and `CKAN_SYSADMIN_PASSWORD` (`ckan_admin` and `test1234` by default). All ennvars with `API_TOKEN` are automatically regenerated when CKAN is loaded, no editing is required.
|
||
>
|
||
>**This should be obviously changed before running this setup as a public CKAN instance.**
|
||
|
||
3. Build the images:
|
||
```bash
|
||
docker compose build
|
||
```
|
||
|
||
> [!NOTE]
|
||
> You can use a [deploy in 5 minutes](#quick-mode) if you just want to test the package.
|
||
|
||
4. Start the containers:
|
||
```bash
|
||
docker compose up
|
||
```
|
||
|
||
This will start up the containers in the current window. By default the containers will log direct to this window with each container
|
||
using a different colour. You could also use the -d "detach mode" option ie: `docker compose up -d` if you wished to use the current
|
||
window for something else.
|
||
|
||
> [!NOTE]
|
||
> * Or `docker compose up --build` to build & up the containers.
|
||
> * Or `docker compose -f docker-compose.apache.yml up -d --build` to use the Apache HTTP Server version.
|
||
|
||
> [!NOTE]
|
||
> Learn more about configuring this ckan docker:
|
||
> - [Backup the CKAN Database](#ckan-backups)
|
||
> - [Configuring a docker compose service to start on boot](#docker-compose-configure-a-docker-compose-service-to-start-on-boot)
|
||
|
||
At the end of the container start sequence there should be 6 containers running (or 5 if use NGINX Docker Compose file)
|
||
|
||
After this step, CKAN should be running at {`PROXY_SERVER_NAME`}{`PROXY_CKAN_LOCATION`} and ckan-pycsw at {`PROXY_SERVER_NAME`}{`PROXY_PYCSW_LOCATION`}, i.e: http://localhost/catalog or http://localhost/csw

|
||
|
||
### Quick mode
|
||
If you just want to test the package and see the general functionality of the platform, you can use the `ckan-docker` image from the [Github container registry](https://github.com/mjanez/ckan-docker/pkgs/container/ckan-docker):
|
||
|
||
```bash
|
||
cp .env.example .env
|
||
# Edit the envvars in the .env as you like and start the containers.
|
||
docker compose -f docker-compose.ghcr.yml up -d --build
|
||
```
|
||
|
||
It will download the pre-built image and deploy all the containers. Remember to use your own domain by changing `localhost` in the `.env` file.
|
||
|
||
|
||
### Development mode
|
||
Use this mode if you are making code changes to CKAN and either creating new extensions or making code changes to existing extensions. This mode also uses the `.env` file for config options.
|
||
|
||
To develop local extensions use the `docker compose.dev.yml` file:
|
||
|
||
To build the images:
|
||
|
||
docker compose -f docker-compose.dev.yml build
|
||
|
||
To start the containers:
|
||
|
||
docker compose -f docker-compose.dev.yml up
|
||
|
||
See [CKAN images](#5-ckan-images) for more details of what happens when using development mode.
|
||
See [CKAN images](#5-ckan-images) for more details of what happens when using development mode.
|
||
|
||
#### Create an extension
|
||
You can use the ckan [extension](https://docs.ckan.org/en/latest/extensions/tutorial.html#creating-a-new-extension) instructions to create a CKAN extension, only executing the command inside the CKAN container and setting the mounted `src/` folder as output:
|
||
|
||
```bash
|
||
docker compose -f docker-compose.dev.yml exec ckan-dev /bin/sh -c "ckan -c /srv/app/ckan.ini generate extension --output-dir /srv/app/src_extensions"
|
||
```
|
||
|
||
Then, answer the prompts to configure the plugin:
|
||
|
||
```bash
|
||
Extension's name [must begin 'ckanext-']: ckanext-newextension
|
||
Author's name []: Joe Bloggs
|
||
Author's email []: joe@bloggs.com
|
||
Your Github user or organization name []: joebloggs
|
||
Brief description of the project []: test creating a new extension
|
||
List of keywords (separated by spaces) [CKAN]: ckanext-newextension
|
||
Do you want to include code examples? [y/N]: y
|
||
|
||
Written: /srv/app/src_extensions/ckanext-newextension
|
||
```
|
||
|
||
The new extension files and directories are created in the `/srv/app/src_extensions/` folder in the running container. They will also exist in the local src/ directory as local `/src` directory is mounted as `/srv/app/src_extensions/` on the ckan container. You might need to change the owner of its folder to have the appropiate permissions.
|
||
|
||
#### Running HTTPS on development mode
|
||
Sometimes is useful to run your local development instance under HTTPS, for instance if you are using authentication extensions like [ckanext-saml2auth](https://github.com/keitaroinc/ckanext-saml2auth). To enable it, set the following in your `.env` file:
|
||
|
||
```ini
|
||
USE_HTTPS_FOR_DEV=true
|
||
```
|
||
|
||
and update the site URL setting:
|
||
|
||
```ini
|
||
CKAN_SITE_URL=https://localhost:5000
|
||
```
|
||
|
||
After recreating the `ckan-dev` container, you should be able to access CKAN at https://localhost:5000
|
||
|
||
## CKAN images
|
||
|
||
|
||
The Docker image config files used to build your CKAN project are located in the `ckan/` folder. There are two Docker files:
|
||
|
||
* `Dockerfile`: this is based on `mjanez/ckan-base-spatial:<version>`, a base image located in the [Github Package Registry](https://github.com/mjanez/ckan-docker/pkgs/container/ckan-base-spatial), that has CKAN installed along with all its dependencies, properly configured and running on [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/) (production setup)
|
||
* `Dockerfile.dev`: this is based on `mjanez/ckan-base-spatial:<version>-dev` also located located in the Github Package Registry, and extends `mjanez/ckan-base-spatial:<version>` to include:
|
||
|
||
* Any extension cloned on the `./src` folder will be installed in the CKAN container when booting up Docker Compose (`docker compose up`). This includes installing any requirements listed in a `requirements.txt` (or `pip-requirements.txt`) file and running `python setup.py develop`.
|
||
* CKAN is started running this: `/usr/bin/ckan -c /srv/app/ckan.ini run -H 0.0.0.0`.
|
||
* Make sure to add the local plugins to the `CKAN__PLUGINS` env var in the `.env` file.
|
||
|
||
* Any custom changes to the scripts run during container start up can be made to scripts in the `setup/` directory. For instance if you wanted to change the port on which CKAN runs you would need to make changes to the Docker Compose yaml file, and the `start_ckan.sh.override` file. Then you would need to add the following line to the Dockerfile ie: `COPY setup/start_ckan.sh.override ${APP_DIR}/start_ckan.sh`. The `start_ckan.sh` file in the locally built image would override the `start_ckan.sh` file included in the base image

## CKAN images enhancement
|
||
### Extending the base images
|
||
You can modify the docker files to build your own customized image tailored to your project, installing any extensions and extra requirements needed. For example here is where you would update to use a different CKAN base image ie: `ckan/ckan-base-spatial:<new version>`
|
||
|
||
To perform extra initialization steps you can add scripts to your custom images and copy them to the `/docker-entrypoint.d` folder (The folder should be created for you when you build the image). Any `*.sh` and `*.py` file in that folder will be executed just after the main initialization script ([`prerun.py`](https://github.com/ckan/ckan-docker-base/blob/main/ckan-2.9/base/setup/prerun.py)) is executed and just before the web server and supervisor processes are started.
|
||
|
||
For instance, consider the following custom image:
|
||
|
||
```bash
|
||
ckan
|
||
├── docker-entrypoint.d
|
||
│ └── setup_validation.sh
|
||
├── Dockerfile
|
||
└── Dockerfile.dev
|
||
```
|
||
|
||
We want to install an extension like [ckanext-validation](https://github.com/frictionlessdata/ckanext-validation) that needs to create database tables on startup time. We create a `setup_validation.sh` script in a `docker-entrypoint.d` folder with the necessary commands:
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
# Create DB tables if not there
|
||
ckan -c /srv/app/ckan.ini validation init-db
|
||
```
|
||
|
||
And then in our `Dockerfile.dev` file we install the extension and copy the initialization scripts:
|
||
|
||
```Dockerfile
|
||
FROM ckan/ckan-base-spatial:2.9.11
|
||
|
||
RUN pip install -e git+https://github.com/frictionlessdata/ckanext-validation.git#egg=ckanext-validation && \
|
||
pip install -r https://raw.githubusercontent.com/frictionlessdata/ckanext-validation/master/requirements.txt
|
||
|
||
COPY docker-entrypoint.d/* /docker-entrypoint.d/
|
||
```
|
||
|
||
NB: There are a number of extension examples commented out in the Dockerfile.dev file
|
||
|
||
### Applying patches
|
||
When building your project specific CKAN images (the ones defined in the `ckan/` folder), you can apply patches
|
||
to CKAN core or any of the built extensions. To do so create a folder inside `ckan/patches` with the name of the
|
||
package to patch (ie `ckan` or `ckanext-??`). Inside you can place patch files that will be applied when building
|
||
the images. The patches will be applied in alphabetical order, so you can prefix them sequentially if necessary.
|
||
|
||
For instance, check the following example image folder:
|
||
|
||
```bash
|
||
ckan
|
||
├── patches
|
||
│ ├── ckan
|
||
│ │ ├── 01_datasets_per_page.patch
|
||
│ │ ├── 02_groups_per_page.patch
|
||
│ │ ├── 03_or_filters.patch
|
||
│ └── ckanext-harvest
|
||
│ └── 01_resubmit_objects.patch
|
||
├── setup
|
||
├── Dockerfile
|
||
└── Dockerfile.dev
|
||
|
||
```

### Debugging
|
||
#### Debugging CKAN Development Instance with VSCode Dev Containers and debugpy
|
||
|
||
The [Visual Studio Code Dev Containers](https://code.visualstudio.com/docs/devcontainers/containers) extension is a powerful tool that enables developers to use a container as a complete development environment. With this extension, developers can open any folder inside a container and take advantage of the full range of features provided by Visual Studio Code. To do this, developers create a `devcontainer.json `file in their project that specifies how to access or create a development container with a predefined tool and runtime stack. This allows developers to work in an isolated environment, ensuring that the development environment is consistent across team members and that project dependencies are easy to manage.
|
||
|
||
|
||
|
||
To set this up:
|
||
|
||
1. Install [VSCode](https://code.visualstudio.com/).
|
||
|
||
2. Install the [Remote Development extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack) for VSCode.
|
||
|
||
3. In your project directory, create a `devcontainer.json` file. This file will contain the configuration for your development container.
|
||
|
||
4. In the `devcontainer.json` file, specify the Docker image for your development container and any additional configuration settings, such as environment variables, ports to expose, and startup commands.
|
||
|
||
5. Enable `debugpy` for your development instance in your `.env` file:
|
||
|
||
```ini
|
||
USE_DEBUGPY_FOR_DEV=true
|
||
```
|
||
|
||
6. Start the containers in [development mode](#development-mode) and launch VS Code.
|
||
|
||
7. Install the "Dev Container" extension: press `CTRL+SHIFT+X`, type "dev container", click "install".
|
||
|
||
8. Click the `Open a Remote Window` button in the bottom-left of the VS Code window.
|
||
|
||
9. Click `Attach to Running Container...` and select your ckan-dev container, e.g. `ckan-docker-ckan-dev-1`.
|
||
|
||
10. Click the `Run and Debug` icon on the left panel then `create a launch.json`, select `Python Debugger`, `Remote Attach`, host `localhost` and port `5678`.
|
||
|
||
11. Press `F5` or click the `Run` menu and `Start Debugging`.
|
||
|
||
You can now set breakpoints and remote debug your CKAN development instance using VSCode Dev Containers and debugpy.
|
||
|
||
#### pdb
|
||
Add these lines to the `ckan-dev` service in the docker compose.dev.yml file
|
||
|
||
```yaml
|
||
ports:
|
||
- "0.0.0.0:${CKAN_PORT}:5000"
|
||
|
||
stdin_open: true
|
||
tty: true
|
||
```
|
||
|
||
Debug with pdb (example) - Interact with `docker attach $(docker container ls -qf name=ckan)`
|
||
|
||
command: `python -m pdb /usr/lib/ckan/venv/bin/ckan --config /srv/app/ckan.ini run --host 0.0.0.0 --passthrough-errors`
|
||
|
||
|
||
### Reverse proxy
|
||
#### NGINX
|
||
The default Docker Compose configuration ([`docker-compose.yml`](/docker-compose.yml)) uses an NGINX image as the front-end (ie: reverse proxy). It includes HTTPS running on port number 8443 and an HTTP port (81). A "self-signed" SSL certificate is generated beforehand and the server certificate and key files are included. The NGINX `server_name` (ENV: `PROXY_SERVER_NAME`) directive and the `CN` field in the SSL certificate have been both set to 'localhost'. This should obviously not be used for production.
|
||
|
||
The proxy locations, ports and other NGINX options can be modified in the `.env` file:
|
||
```ini
|
||
# Host Ports
|
||
NGINX_PORT_HOST=81
|
||
NGINX_SSLPORT_HOST=8443
|
||
|
||
# NGINX
|
||
NGINX_PORT=80
|
||
NGINX_SSLPORT=443
|
||
NGINX_LOG_DIR=/var/log/nginx
|
||
|
||
# Check CKAN__ROOT_PATH and CKANEXT__DCAT__BASE_URI. If you don't need to use domain locations, it is better to use the nginx configuration. Leave blank or use the root `/`.
|
||
PROXY_SERVER_NAME=localhost
|
||
PROXY_CKAN_LOCATION=/catalog
|
||
PROXY_PYCSW_LOCATION=/csw
|
||
```
|
||
The base Docker Compose configuration uses an NGINX image as the front-end (ie: reverse proxy). It includes HTTPS running on port number 8443. A "self-signed" SSL certificate is generated as part of the ENTRYPOINT. The ENV `PROXY_SERVER_NAME`, NGINX `server_name` directive and the `CN` field in the SSL certificate have been both set to 'localhost'. This should obviously not be used for production.
|
||
|
||
Creating the SSL cert and key files as follows:
|
||
`openssl req -new -newkey rsa:4096 -days 365 -nodes -x509 -subj "/C=DE/ST=Berlin/L=Berlin/O=None/CN=localhost" -keyout ckan-local.key -out ckan-local.crt`
|
||
The `ckan-local.*` files will then need to be moved into the nginx/setup/ directory
|
||
|
||
|
||
#### Apache HTTP Server
|
||
The Docker Compose configuration ([`docker-compose.apache.yml`](/docker-compose.apache.yml)) uses an httpd image as the front-end. It has two routes for the ckan (default location: `/catalog`) and ckan-pycsw (default location: `/csw`) services.
|
||
|
||
The proxy locations, ports and other Apache Web Server options can be modified in the `.env` file:
|
||
```ini
|
||
# Host Ports
|
||
APACHE_PORT_HOST=81
|
||
|
||
# Apache HTTP Server
|
||
APACHE_VERSION=2.4-alpine
|
||
APACHE_PORT=80
|
||
APACHE_LOG_DIR=/var/log/apache
|
||
|
||
# Check CKAN__ROOT_PATH and CKANEXT__DCAT__BASE_URI. If you don't need to use domain locations, it is better to use the nginx configuration. Leave blank or use the root `/`.
|
||
PROXY_SERVER_NAME=localhost
|
||
PROXY_CKAN_LOCATION=/catalog
|
||
PROXY_PYCSW_LOCATION=/csw
|
||
```
|
||
|
||
|
||
### envvars
|
||
The ckanext-envvars extension is used in the CKAN Docker base repo to build the base images.
|
||
This extension checks for environmental variables conforming to an expected format and updates the corresponding CKAN config settings with its value.
|
||
|
||
For the extension to correctly identify which env var keys map to the format used for the config object, env var keys should be formatted in the following way:
|
||
|
||
All uppercase
|
||
Replace periods ('.') with two underscores ('__')
|
||
Keys must begin with 'CKAN' or 'CKANEXT', if they do not you can prepend them with '`CKAN___`'
|
||
|
||
For example:
|
||
|
||
* `CKAN__PLUGINS="envvars image_view text_view recline_view datastore datapusher"`
|
||
* `CKAN__DATAPUSHER__CALLBACK_URL_BASE=http://ckan:5000`
|
||
* `CKAN___BEAKER__SESSION__SECRET=CHANGE_ME`
|
||
|
||
These parameters can be added to the `.env` file
|
||
|
||
For more information please see [ckanext-envvars](https://github.com/okfn/ckanext-envvars)
|
||
|
||
|
||
### Datastore
|
||
The Datastore database and user is created as part of the entrypoint scripts for the db container.
|
||
|
||
|
||
### xloader
|
||
To replacing DataPusher with XLoader check out the wiki page for this: https://github.com/ckan/ckan-docker/wiki/Replacing-DataPusher-with-XLoader
|
||
|
||
|
||
### ckan-pycsw
|
||
[ckan-pycsw](https://github.com/mjanez/ckan-pycsw) is a docker compose environment (based on [pycsw](https://github.com/geopython/pycsw)) for development and testing with CKAN Open Data portals.[^5]
|
||
|
||
Available components:
|
||
* **pycsw**: The pycsw app. An [OARec](https://ogcapi.ogc.org/records) and [OGC CSW](https://opengeospatial.org/standards/cat) server implementation written in Python.
|
||
* **ckan2pycsw**: Software to achieve interoperability with the open data portals based on CKAN. To do this, ckan2pycsw reads data from an instance using the CKAN API, generates ISO-19115/ISO-19139 metadata using [pygeometa](https://geopython.github.io/pygeometa/), or a custom schema that is based on a customized CKAN schema, and populates a [pycsw](https://pycsw.org/) instance that exposes the metadata using CSW and OAI-PMH.
|
||
|
||
### Harvester consumers on a deployed CKAN
|
||
[ckanext-harvest supervisor](https://github.com/ckan/ckanext-harvest#setting-up-the-harvesters-on-a-production-server) allows you to harvest metadata from multiple sources on a production deployment. Here it is deployed [by a worker consumers in the `ckan` container](./ckan/setup/workers/harvester.conf), also the `ckanext-harvest` extension and other custom harvesters ([`ckanext-schemingdcat`](https://github.com/mjanez/ckanext-schemingdcat?tab=readme-ov-file#harvesters) or [`ckanext-dcat`](https://github.com/ckan/ckanext-dcat#rdf-dcat-harvester)) are included in the CKAN docker images.
|
||
|
||
> ![TIP]
|
||
> To enable harvesters you need to set up in the `.env` file the `CKAN__PLUGINS` variable with the `harvest` plugin: https://github.com/mjanez/ckan-docker/blob/a18e0c80d9f16b6d9b6471e3148d48fcb83712bd/.env.example#L126-L127

## ckan-docker tips
|
||
### CKAN. Backups
|
||
PostgreSQL offers the command line tools [`pg_dump`](https://www.postgresql.org/docs/current/static/app-pgdump.html) and [`pg_restore`](https://www.postgresql.org/docs/current/static/app-pgrestore.html) for dumping and restoring a database and its content to/from a file.
|
||
|
||
|
||
#### Backup service for db container
|
||
1. Create a new file called `ckan_backup_custom.sh` and open it in your preferred text editor.
|
||
|
||
2. Add the following code to the script, replacing the placeholders with your actual values:
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
# Set the necessary variables
|
||
CONTAINER_NAME="db"
|
||
DATABASE_NAME="ckandb"
|
||
POSTGRES_USER="postgres"
|
||
POSTGRES_PASSWORD="your_postgres_password"
|
||
BACKUP_DIRECTORY="/path/to/your/backup/directory"
|
||
DATE=$(date +%Y%m%d%H%M%S)
|
||
MONTH=$(date +%m)
|
||
YEAR=$(date +%Y)
|
||
|
||
# Create the monthly backup directory if it doesn't exist
|
||
mkdir -p "$BACKUP_DIRECTORY/monthly/$YEAR-$MONTH"
|
||
|
||
# Run the backup command
|
||
docker exec -e PGPASSWORD=$POSTGRES_PASSWORD $CONTAINER_NAME pg_dump -U $POSTGRES_USER -Fc $DATABASE_NAME > "$BACKUP_DIRECTORY/monthly/$YEAR-$MONTH/ckan_backup_$DATE.dump"
|
||
|
||
# Compress the dump files into a zip archive
|
||
cd "$BACKUP_DIRECTORY/monthly/$YEAR-$MONTH" || exit
|
||
zip "backup_${YEAR}-${MONTH}.zip" *.dump
|
||
|
||
# Remove the original dump files
|
||
rm -f *.dump
|
||
```
|
||
|
||
3. Replace the following placeholders with your actual values:
|
||
- `your_postgres_password`: The password for the PostgreSQL user.
|
||
- `/path/to/your/backup/directory`: The path to the directory where you want to store the backup files.
|
||
|
||
> [!WARNING]
|
||
> If you have changed the values of the PostgreSQL container, database or user, change them too.
|
||
> Check that `zip` package is installed: `sudo apt-get install zip`
|
||
|
||
4. Save and close the file.
|
||
|
||
5. Make the script executable:
|
||
|
||
```bash
|
||
chmod +x ckan_backup_custom.sh
|
||
```
|
||
|
||
6. Open the crontab for the current user:
|
||
|
||
```bash
|
||
crontab -e
|
||
```
|
||
|
||
7. Add the following line to schedule the backup to run daily at midnight (adjust the schedule as needed):
|
||
|
||
```sh
|
||
0 0 * * * /path/to/your/script/ckan_backup_custom.sh
|
||
```
|
||
|
||
> [!NOTE]
|
||
> Replace `/path/to/your/script` with the actual path to the `ckan_backup_custom.sh` script.
|
||
|
||
8. Save and close the file.
|
||
|
||
The cronjob is now set up and will backup your CKAN PostgreSQL database daily at midnight using the custom format. The backups will be stored in the specified directory with the timestamp in the filename.
|
||
|
||
> [!NOTE]
|
||
> Sample scripts for backing up CKAN: [`doc/scripts`](doc/scripts)
|
||
|
||
|
||
#### Restore a backup
|
||
If need to use a backup, restore it:
|
||
|
||
1. First clean the database. **Caution, this will delete all data from your CKAN database!**
|
||
|
||
```bash
|
||
docker exec -it ckan /bin/bash -c "export TERM=xterm; exec bash"
|
||
|
||
# Delete everything in the CKAN database, including the tables, to start from scratch
|
||
ckan -c $CKAN_INI db clean
|
||
```
|
||
|
||
2. After cleaning the database you must do either [initialize it](https://docs.ckan.org/en/2.9/maintaining/database-management.html#initialization) or import a previously created dump.
|
||
|
||
```bash
|
||
docker exec -i -e PGPASSWORD=$POSTGRES_PASSWORD $POSTGRESQL_CONTAINER_NAME pg_restore -U $POSTGRES_USER --clean --if-exists -d $DATABASE_NAME < /path/to/your/backup/directory/ckan.dump
|
||
```
|
||
3. Restart the `ckan` container.
|
||
|
||
|
||
### CKAN. Manage new users
|
||
|
||
1. Create a new user from the Docker host, for example to create a new user called `user_example`
|
||
|
||
```bash
|
||
docker exec -it <container-id> ckan -c ckan.ini user add user_example email=user_example@localhost
|
||
|
||
# Admin user
|
||
docker exec -it <container-id> ckan -c ckan.ini sysadmin add admin_example email=admin_example@localhost name=admin_example
|
||
```
|
||
|
||
To delete the 'user_example' user
|
||
|
||
```bash
|
||
docker exec -it <container-id> ckan -c ckan.ini user remove user_example`
|
||
```
|
||
|
||
1. Create a new user from within the ckan container. You will need to get a session on the running container
|
||
|
||
```bash
|
||
ckan -c ckan.ini user add user_example email=user_example@localhost`
|
||
```
|
||
|
||
To delete the 'user_example' user
|
||
```bash
|
||
ckan -c ckan.ini user remove user_example`
|
||
```
|
||
### Docker. Basic commands
|
||
For more information about Docker and Docker Compose's basic commands and post-installation procedures, see [Docker/Docker Compose Info](./doc/info_docker.md)
|
||
|
||
### Docker Compose. Configure a docker compose service to start on boot
|
||
To have Docker Compose run automatically when you reboot a machine, you can follow the steps below:
|
||
1. Create a systemd service file for Docker Compose. You can create a file named `ckan-docker-compose.service` in the `/etc/systemd/system/` folder with the following content:
|
||
|
||
```bash
|
||
[Unit]
|
||
Description=CKAN Docker Compose Application Service
|
||
Requires=docker.service
|
||
After=docker.service
|
||
|
||
[Service]
|
||
User=docker
|
||
Group=docker
|
||
Type=oneshot
|
||
RemainAfterExit=yes
|
||
WorkingDirectory=/path/to/project/ckan-docker/
|
||
ExecStart=/bin/docker compose up -d
|
||
ExecStop=/bin/docker compose down
|
||
TimeoutStartSec=0
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
2. Replace `/path/to/project/ckan-docker/` with the path where your project's `docker-compose.yml` file is located and and check the path to the docker compose binary on execution and stop: `/bin/docker`. Also change the `User` / `Group` to execute the service.
|
||
3. Load the systemd service file with the following command:
|
||
|
||
```bash
|
||
sudo systemctl daemon-reload
|
||
```
|
||
|
||
4. Enables the service to start automatically when the machine boots up:
|
||
|
||
```bash
|
||
sudo systemctl enable ckan-docker-compose
|
||
```
|
||
|
||
5. You can now start the service with the following command:
|
||
|
||
```bash
|
||
sudo systemctl start ckan-docker-compose
|
||
```
|
||
|
||
6. If you want to stop or check the status of the service, use the following commands:
|
||
|
||
```bash
|
||
# Stop the service
|
||
sudo systemctl stop ckan-docker-compose
|
||
|
||
# Check the status
|
||
sudo systemctl status ckan-docker-compose
|
||
```
|
||
|
||
|
||
