Docker Cheat sheet

We have completed the Docker and Docker-compose hands-on and we have learned something interesting from it.

Now it's time to take our Docker skills to the next level by creating a comprehensive cheat sheet of all the commands we've learned so far.

So let's make a cheat sheet that will include commands for both Docker and Docker-Compose, as well as brief explanations of their usage.

Docker Commands

Build an image

• Build an image using a file named Dockerfile -

  docker build .

• Build an image using a file named Dockerfile -

  docker build -f "Dockerfile_client" .

• Give a name to the image

  docker build -t "any_name" .

Manage images

• List images

  docker image ls

• Remove an image

  docker image rm <img_name>

• Tag an image

  docker tag <img_name>:tag

• Display the image history

  docker history <img_name>

• Display low-level information about an image

  docker inspect <img_name>

• Save an image to a tar file

  docker save <image_name> --output <filename.tar>

• Load an image from a tar archive

  docker load --input <filename.tar>

Create container

• Create a container from an image

  docker create <img_name>

• Create and run a container from an image

  docker run <img_name>

• Create and run a container and give a name to it

  docker run --name <container_name> <img_name>

• Create and run a container and run it in detached mode.

  docker run -d <img_name>

  docker run --detach <img_name>

• Create and run a container and set environment variables.

  docker run -e VAR_NAME=VALUE <img_name>

  docker run --env VAR_NAME=VALUE <img_name>

• Create and run a container and specify a network,

  docker run --network="<any_network>" <img_name>

• Create and run a container and map the host's port number to the container's port number.

  docker run -p <host_port_no:cntnr_port_no> <img_name>

  docker run -p 8080:8080 <img_name>

• Create and run a container and remove it when it stops

  docker run --rm <img_name>

• Create and run a container and mount a shared directory

  docker run -v C:/Downloads/:/home/ubuntu/work <img_name>

• Create and run a container and go in it

  docker run -it <img_name>

Manage containers

• Stop a container

  docker stop <container>

• Start a stopped container

  docker start <container>

• Pause a container

  docker pause <container>

• Unause a container

  docker unpause <container>

• Restart a running or stopped container

  docker restart <container>

• Export a container to a tar file

  docker export <container> > <filename>.tar

  docker export --output="<filename>.tar" <container>

• Execute some commands in a running container

  docker exec -it <container> bash

• Create a new image from a container

  docker commit <container> <img_name>

• List all running containers

  docker ps

• List all running and stopped containers

  docker -ps -a

• Display low-level information about a container

  docker inspect <container>

• Gather the logs for a container

  docker logs <container>

• Show container resource usage statistics

  docker stats <container>

Registry Commands

• Log in to a registry

  docker login

• Log out from a registry

  docker logout

• Pull an image from a registry

  docker pull <img_name>

• Push an image to a registry

  docker push <repo/img_name>:<tag>

Network Commands

• Create a new network

  docker network create <networkname>

• Remove a specified network

  docker network rm <networkname>

• List all networks

  docker network ls

• Connect a container to a network

  docker network connect <networkname> <container>

• Disconnect a container from a network

  docker network disconnect <networkname> <container>

• Display detailed information about a network

  docker network inspect <networkname

Docker-Compose Commands

• To build images for services

  docker-compose build - Build all services

  docker-compose build <web> - Build a single service named web

• To create docker containers

  docker-compose up -d - Create all containers

  docker-compose up -d <web> - Create a single container named web

• To stop and delete all containers, network and associated images

  docker-compose down - Stop and delete all containers

  docker-compose down <web> - Stop and delete a single container named web

• To list all containers created with their status, port bindings and command.

  docker-compose ps

• To execute a command to the running container.

  docker-compose exec <container> ls -l

• To start a stopped container.

  docker-compose start - Start all containers

  docker-compose start <web> - Start single container named web

• To stop running containers

  docker-compose stop - Stop all containers

  docker-compose stop <web> - Stop single container named web

• To restart containers

  docker-compose restart - Restart all containers

  docker-compose restart <web> - Restart single container named web

• To pause running containers

  docker-compose pause - Pause all containers

  docker-compose pause <web> - Pause single container named web

• To start paused containers

  docker-compose unpause - Start all paused containers

  docker-compose unpause <web> - Start a single paused container named web

• To remove stopped containers

  docker-compose rm - Remove all stopped containers

  docker-compose rm <web> - Remove a single stopped container named web

That's all for docker and docker-compose. We can use this cheatsheet anytime we work docker and docker-compose
