Overview

Contains Docker images for the different components of CKAN Cloud and a Docker compose environment (based on ckan) for development and testing Open Data portals.

Warning:
This is a custom installation of Docker Compose with specific extensions for spatial data and GeoDCAT-AP/INSPIRE metadata profiles. For official installations, please have a look: CKAN documentation: Installation.

Available components:

• CKAN custom multi-stage build with spatial capabilities from ckan-docker-spatial¹, 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-spatial:ckan-2.9.8	Stable version with CKAN 2.9.9
2.9.9	latest custom image	ghcr.io/mjanez/ckan-spatial:master	Latest ckan-spatial image.

The non-CKAN images are as follows:

• PostgreSQL: Custom image based on official PostgreSQL image. Database files are stored in a named volume.
• Solr: CKAN's pre-configured Solr image. The index data is stored in a named volume and has a spatial schema. ²
• Redis: standard Redis image
• Apache HTTP Server: Custom image based on official latest stable httpd image. Configured to serve multiple routes for the ckan-pycsw CSW endpoint ({CKAN_SITE_URL}/csw) and CKAN ({CKAN_SITE_URL}/catalog).
• ckan-pycsw: Custom image based on pycsw CKAN harvester ISO19139 for INSPIRE Metadata CSW Endpoint.

Optional HTTP Endpoint (docker-compose.nginx.yml):

• docker-compose.nginx.yml:
  • NGINX: latest stable nginx image that includes SSL and Non-SSL endpoints instead of Apache HTTP Server. No locations, no ckan-pycsw, only CKAN.

Compose files	Repository	Type	Docker tag	Size	Notes
docker-compose.yml / docker-compose.nginx.yml	CKAN 2.9.8	custom image	mjanez/ckan-spatial:ckan-2.9.8	800 MB	Custom Dockerfile: ckan/Dockerfile
docker-compose.yml / docker-compose.nginx.yml	PostgreSQL 15.2	base image	postgres/postgres:15-alpine	89.74 MB	Custom Dockerfile: postgresql/Dockerfile
docker-compose.yml / docker-compose.nginx.yml	Solr 8.11.1	custom image	ckan/ckan-solr:2.9-solr8-spatial	331.1 MB	CKAN's pre-configured spatial Solr image.
docker-compose.yml / docker-compose.nginx.yml	Redis 7.0.10	base image	redis/redis:7-alpine	11.82 MB	-
docker-compose.yml	Apache HTTP Server 2.4	custom image	httpd/httpd:2.4	54.47 MB	Custom Dockerfile: apache/Dockerfile
docker-compose.yml	pycsw CKAN harvester ISO19139	custom image	mjanez/ckan-pycsw:latest	175 MB	Custom Dockerfile: ckan-pycsw/Dockerfile
docker-compose.nginx.yml	NGINX 1.22.1	base image	nginx:stable-alpine	9.74 MB	No routing, only CKAN. Custom Dockerfile: nginx/Dockerfile

The site is configured using environment variables that you can set in the .env file for an Apache HTTP Server and ckan-pycsw deployment (default .env.example), or replace it with the .env.nginx.example for a NGINX and CKAN-only deployment using the Docker Compose file: docker-compose.nginx.yml.

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 for more information.

Upgrade docker-engine

To upgrade Docker Engine, first run sudo apt-get update, then follow the installation instructions, 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.

Note
Learn more about Docker/Docker Compose basic commands.

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

   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/) and modify the resulting .env to suit your needs.

   cp .env.example .env
   

   • Apache HTTP Server & CKAN/ckan-pycsw endpoints: Modifiy the variables about the site URL or locations (CKAN_SITE_URL CKAN_URL, PYCSW_URL, CKANEXT__DCAT__BASE_URI, APACHE_SERVER_NAME, APACHE_CKAN_LOCATION, APACHE_PYCSW_LOCATION, etc.).

   • NGINX only CKAN: Replace the .env with the /samples/.env.nginx.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:

   docker compose build 
   

   Note
   You can use a deploy in 5 minutes if you just want to test the package.

4. Start the containers:

   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.nginx.yml up -d --build to use the NGINX version.

Note
Learn more about configuring this ckan docker:

• Backup the CKAN Database
• Configuring 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 {APACHE_SERVER_NAME}{APACHE_CKAN_LOCATION} and ckan-pycsw at {APACHE_SERVER_NAME}{APACHE_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-spatial image from the Github container registry:

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 for more details of what happens when using development mode.

Create an extension

You can use the ckan extension instructions to create a CKAN extension, only executing the command inside the CKAN container and setting the mounted src/ folder as output:

docker compose -f docker compose.dev.yml exec ckan-dev /bin/sh -c "ckan generate extension --output-dir /srv/app/src_extensions"

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.

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 ckan/ckan-base-spatial:<version>, a base image located in the Github Package Registry, that has CKAN installed along with all its dependencies, properly configured and running on uWSGI (production setup)

• Dockerfile.dev: this is based on ckan/ckan-base-spatial:<version>-dev also located located in the Github Package Registry, and extends ckan/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

Note
If you get an error like doesn't have execute permissions:

Daemon error response: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/srv/app/start_ckan.sh": permission denied: unknown

It may be necessary to give execute permissions to the file in the Dockerfile:

...
# Override start_ckan.sh
COPY setup/start_ckan.sh.override ${APP_DIR}/start_ckan.sh
RUN chmod +x ${APP_DIR}/start_ckan.sh
...

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) is executed and just before the web server and supervisor processes are started.

For instance, consider the following custom image:

ckan
├── docker-entrypoint.d
│   └── setup_validation.sh
├── Dockerfile
└── Dockerfile.dev

We want to install an extension like 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:

#!/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:

FROM ckan/ckan-base-spatial:2.9.8

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:

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

Note:
Git diff is a command to output the changes between two sources inside the Git repository. The data sources can be two different branches, commits, files, etc.

• Show changes between working directory and staging area: git diff > [file.patch]
• Shows any changes between the staging area and the repository: git diff --staged [file]

VSCode dev containers

The Visual Studio Code Dev 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.

1. Install VSCode.

2. Install the Remote Development extension for VSCode.

3. In your project directory, create a file named devcontainer.json. This file will contain the configuration for your dev container.

4. In the devcontainer.json file, specify the Docker image that you want to use for your dev container.

5. Specify any additional configuration settings for your dev container, such as environment variables, ports to expose, and startup commands.

6. Open your project in a dev container by using the Remote Development extension in VSCode. You can do this by clicking the Open Folder in Container button in the command palette or by opening the folder using the Remote-Containers: Open Folder in Container command. Also you can attach to an active container Attach to Running Container.

7. VSCode will start a new container based on the configuration settings in your devcontainer.json file. Once the container is started, you can work on your project just like you would on your local machine.

pdb

Add these lines to the ckan-dev service in the docker compose.dev.yml file

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

Datastore

The Datastore database and user is created as part of the entrypoint scripts for the db container.

Apache HTTP Server

The default Docker Compose configuration (docker-compose.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.

Both web locations can be modified in the .env file:

...

# Apache HTTP Server
APACHE_VERSION=2.4
APACHE_PORT=80
APACHE_LOG_DIR=/var/log/apache
APACHE_SERVER_NAME=mjanez-cautious-lamp-4pjq9vpg967hq447-80.preview.app.github.dev
# 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 `/`.
APACHE_CKAN_LOCATION=/catalog
APACHE_PYCSW_LOCATION=/csw

...

NGINX

Warning
The nginx docker compose file only deploys the CKAN service, not ckan-pycsw.

The nginx Docker Compose configuration (docker-compose.nginx.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 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

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'

For example:

• CKAN__PLUGINS="envvars image_view text_view recline_view datastore datapusher"
• CKAN__DATAPUSHER__CALLBACK_URL_BASE=http://ckan:5000

These parameters can be added to the .env file

For more information please see ckanext-envvars

ckan-pycsw

ckan-pycsw is a docker compose environment (based on pycsw) for development and testing with CKAN Open Data portals.⁵

Available components:

• pycsw: The pycsw app. An OARec and OGC CSW 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, or a custom schema that is based on a customized CKAN schema, and populates a pycsw instance that exposes the metadata using CSW and OAI-PMH.

ckan-docker tips

CKAN. Backups

PostgreSQL offers the command line tools pg_dump and pg_restore 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:

   #!/bin/bash
   
   # Set the necessary variables
   POSTGRESQL_CONTAINER_NAME="db"
   DATABASE_NAME="ckan"
   POSTGRES_USER="ckan"
   POSTGRES_PASSWORD="your_postgres_password"
   BACKUP_DIRECTORY="/path/to/your/backup/directory"
   DATE=`date +%Y%m%d%H%M%S`
   
   # Run the backup command
   docker exec -e PGPASSWORD=$POSTGRES_PASSWORD $POSTGRESQL_CONTAINER_NAME pg_dump -U $POSTGRES_USER -Fc $DATABASE_NAME > $BACKUP_DIRECTORY/ckan_backup_$DATE.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.

4. Save and close the file.

5. Make the script executable:

   chmod +x ckan_backup_custom.sh
   

6. Open the crontab for the current user:

   crontab -e
   

7. Add the following line to schedule the backup to run daily at midnight (adjust the schedule as needed):

   0 0 * * * /path/to/your/script/ckan_backup_custom.sh
   

   Info
   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.

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!

   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 or import a previously created dump.

   docker exec -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
   

Docker. Basic commands

Linux post-install steps

These optional post-installation procedures shows you how to configure your Linux host machine to work better with Docker. For example, managing docker with a non-root user.

Configure Docker to start on boot

sudo systemctl enable docker

# To disable this behavior, use disable instead.
sudo systemctl disable docker

Clear all Docker unused objects (images, containers, networks, local volumes)

docker system prune # Clear all

docker image prune # Clear unused images
docker container prune # Clear unused containers
docker volume prune # Clear unused volumes
docker network prune # Clear unused networks

Docker Compose. Basic commands

More info about Docker Compose commands at docker compose reference.

# Basic. All containers or specific container: <container>
## Starts existing containers for a service.
docker compose start <container>

## Restarts existing containers/container for a service.
docker compose restart <container>

## Stops running containers without removing them.
docker compose stop <container>

## Pauses running containers of a service.
docker compose pause <container>

## Unpauses paused containers of a service.
docker compose unpause <container>

# Display the logs of a container. Is it possible to retrieve only the last n seconds or other
docker logs [--since 60s]  <container> -f 

## Lists containers.
docker compose ps

## Remove all docker compose project
docker compose rm <container>


# Build.
## Builds, (re)creates, starts, and attaches to containers for a service.
docker compose [-f <docker compose-file>] up

## Build & up all the containers.
docker compose [-f <docker compose-file>] up -d --build

## To avoid using a cache of the previous build while creating a new image.
docker compose [-f <docker compose-file>] build --no-cache

## Build a project with a specific Docker Compose prefix.
docker compose [-f <docker compose-file>] -p <my_project> up -d --build


# Down
# Stops containers and removes containers, networks, volumes, and images created by up.
docker compose [-p <my_project>] down

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:

   [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:

   sudo systemctl daemon-reload
   

4. Enables the service to start automatically when the machine boots up:

   sudo systemctl enable ckan-docker-compose
   

5. You can now start the service with the following command:

   sudo systemctl start ckan-docker-compose
   

6. If you want to stop or check the status of the service, use the following commands:

   # Stop the service
   sudo systemctl stop ckan-docker-compose
   
   # Check the status
   sudo systemctl status ckan-docker-compose
