# Docker. Basic commands
|
||
|
|
## Linux post-install steps
|
||
|
|
[These optional post-installation procedures](https://docs.docker.com/engine/install/linux-postinstall/) shows you how to configure your Linux host machine to work better with Docker. For example, managing docker with [a non-root user](https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user).
|
||
|
|
|
||
|
|
### Configure Docker to start on boot
|
||
|
|
```bash
|
||
|
|
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)
|
||
|
|
```bash
|
||
|
|
docker system prune # Clear all
|
||
|
|
docker system prune -a # Clear all (includes unused and dangling containers)
|
||
|
|
|
||
|
|
# By default, volumes are not removed to prevent important data from being deleted if there is currently no container using the volume. Use the `--volumes` flag when running the command to prune volumes: `docker system prune -a --volumes`
|
||
|
|
|
||
|
|
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](https://docs.docker.com/compose/reference/).
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# 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
|
||
|
|
|
||
|
|
## Build & up an specific container.
|
||
|
|
docker compose [-f <docker compose-file>] up -d --build <container>
|
||
|
|
|
||
|
|
## 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
|
||
|
|
|
||
|
|
## Log the build
|
||
|
|
docker compose build --no-cache &> docker_build.log
|
||
|
|
|
||
|
|
|
||
|
|
# Down
|
||
|
|
# Stops containers and removes containers, networks, volumes, and images created by up.
|
||
|
|
docker compose [-p <my_project>] down
|
||
|
|
```
