Commands

docker

A list of commands | FreeCodeCamp

docker ps : list all running containers on the system.

docker info : give general info about docker.

docker images : displays all images of docker.

docker inspect [IMAGE_NAME] : get more about a specific image.

docker inspect [IMAGE_ID] : get more about a specific image.

docker image rm [IMAGE_ID] -f : remove the image directly. Here -f forces the execution, because otherwise you would get an error if the image is referenced by more than 1 tag.

docker push ??? : command used to push (upload) a docker container to a container registry somewhere (docker hub, Amazon ECR...)

docker-compose

A docker-compose.yml file is requiered to use, but is very easy to build. It make possible to set rules for multiple container sharing using volumes. It also make it possible communication between containers with service. See the Fireship video on the topic for a quick recap.

docker-compose build : build a container from the docker-compose.yml file.

docker-compose up [CONTAINER_NAME] : run the specified container.

docker-compose down : shut down all containers.

what is docker-compose for ?

See on StackOverflow.

Docker Compose (herein referred to as compose) will use the Dockerfile if you add the build command to your project's docker-compose.yml.

Your Docker workflow should be to build a suitable Dockerfile for each image you wish to create, then use compose to assemble the images using the build command.

Notes

@Cyril RICHARD

1/ Solution pour un dev seul : Docker c'est souvent un peu overkill, et ça dépend des habitudes de chacun mais ça reste exploitable. Pour la gestion des multiples services, un docker compose fait l'affaire. Pour centraliser la gestion des container: Portainer.

Installation process of Docker

Install Docker Engine
Modify user rights
Install Docker compose

check installation :

 ❮ onyr ★  kenzae❯ ❮ ~❯❯ docker --version
Docker version 19.03.13, build 4484c46d9d
 ❮ onyr ★  kenzae❯ ❮ ~❯❯ docker-compose --version
docker-compose version 1.27.4, build 40524192

Uninstallation

docker

Uninstall the Docker Engine, CLI, and Containerd packages:

$ sudo apt-get purge docker-ce docker-ce-cli containerd.io

Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:
```
$ sudo rm -rf /var/lib/docker
```

docker-compose

To uninstall Docker Compose if you installed using curl:

sudo rm /usr/local/bin/docker-compose

What is Portainer :

Portainer allows you to easily build, manage and maintain containerized environments without the need to know CLI, YAML or any other complex syntax. It makes life simple, but not at the expense of functionality or capability. In fact, quite the opposite

Errors

group permissions not loaded

Got permission denied while trying to connect to the Docker daemon socket

Solution available here.

newgrp docker : load new groups policy (allows to skip reboot. Need to be used on every terminal where the docker command will run.
