List of useful docker commands

If you are a complete beginner, then I recommend this website.

Note: First go through the article above, it will make these commands more understandable

  • docker pull busybox: The pull command fetches the busybox image from the Docker registry and saves it to our system.

  • docker images: See a list of all docker images on your system.

  • docker run busybox: Run a Docker container based on the image.

  • docker ps: Shows you all containers that are currently running.

  • docker ps -a:List of all containers that we ran.

  • docker run -it busybox sh: Attaches us to an interactive tty in the container.

  • docker run --help: See a list of all flags run command supports.

  • docker rmi <image_id>: Remove a docker image.

  • docker rm $(docker ps -a -q -f status=exited): Deleting a bunch of stoped containers.

  • docker container prune:Deleting bunch of stopped containers (Similar to above - Supports later versions).

  • docker run -d -P --name static-site prakhar1989/static-site: -d will detach our terminal, -P will publish all exposed ports to random ports, and finally --name corresponds to a name we want to give.

  • docker port static-site: List the ports of static-site container.

  • docker run -p 8888:80 prakhar1989/static-site: Specify a custom port to which the client will forward connections to the container. You can access it at localhost:8888 on your browser.

  • docker stop static-site: Stop a detached container.

  • docker pull ubuntu:18.04: You can pull a specific version of the ubuntu image.

  • docker build -t yourusername/catnip .: The docker build command does the heavy lifting of creating a Docker image from a Dockerfile. It is quite simple - it takes an optional tag name with -t and a location of the directory containing the Dockerfile.

  • docker login: Provide the same credentials that you used for logging into Docker Hub.

  • docker push yourusername/catnip:To publish, just type the below command remembering to replace the name of the image tag above with yours. It is important to have the format of yourusername/image_name so that the client knows where to publish.

  • docker search elasticsearch: Search for an image.

  • docker container ls: Similar to docker ps.

  • docker network ls: List of networks in docker.

  • docker network inspect bridge: To inspect the network.

  • docker network create foodtrucks-net: The network create command creates a new bridge network, which is what we need at the moment. In terms of Docker, a bridge network uses a software bridge which allows containers connected to the same bridge network to communicate, while providing isolation from containers that are not connected to that bridge network.

  • docker container stop es: Stop a container.

  • docker container rm es: Remove a container.

  • docker run -d --net foodtrucks-net -p 5000:5000 --name foodtrucks-web prakhar1989/foodtrucks-web: We can launch our containers inside the custom network using the --net flag.

  • docker-compose up: Compose is a tool that is used for defining and running multi-container Docker apps in an easy way. It provides a configuration file called docker-compose.yml that can be used to bring up an application and the suite of services it depends on with just one command.

  • docker-compose down -v: To destroy the cluster and the data volumes. Otherwise, you would have used: docker stop and docker rm.

  • docker-compose up -d: docker-compose up in detached mode.

  • docker-compose run web bash: Opens the shell inside the web service.
