Finally 🎉
We have completed✅ the Docker hands-on and I hope you have learned something interesting from it.🙌 It's time to take docker to the next level. This cheat sheet will help you to remember everything you learned. This cheat sheet includes commands for both Docker and Docker-Compose, as well as describes the usage of each command.
Here's the Cheat Sheet for docker and docker-compose:
Run a new Container
docker run IMAGE | run a container from the image |
docker run --name CONTAINER IMAGE | assign it a name |
docker run -p 80:80 | assign it a port |
docker run -p IMAGE | to map all ports |
docker run -d IMAGE | run a container in the background |
docker run --hostname | to assign hostname |
Manage Containers
docker ps | show a list of running containers |
docker ps -a | show a list of all containers |
docker rm | to delete a container |
docker rm -f | delete a running container |
docker container prune | delete the stopped containers |
docker stop | stop a running container |
docker start | start a stopped container |
docker cp CONTAINER:SOURCE TARGET | copy a file from the container to the host |
docker cp TARGET CONTAINER:SOURCE | copy a file from the host to a container |
docker exec -it | starts a shell inside a container |
docker rename | rename the container |
docker commit CONTAINER | create an image out of the container |
Manage Images
docker pull IMAGE:TAG | download an image |
docker push IMAGE | upload an image to the repository |
docker rmi | to delete an image |
docker images | show a list of images |
docker image prune | to delete dangling images |
docker image prune -a | delete all the unused images |
docker build | build an image from the Dockerfile |
docker tag IMAGE NEWIMAGE | tag an image |
docker build -t IMAGE DIR | build and tag an image from the docker file |
docker save IMAGE > FILE | save an image to a .tar file |
docker load -i TARFILE | to load the image from a .tar file |
Info & Stats
docker logs CONTAINER | show the logs of a container |
docker stats | show stats of running container |
docker top CONTAINER | show processes of a container |
docker --version | show the version of the docker |
docker inspect NAME | show the detailed info about an object |
docker diff CONTAINER | show all modified files in the container |
docker port CONTAINER | show the mapped port of a container |
Docker-Compose Commands
docker-compose build | to build a docker-compose file |
docker-compose up | to run a docker-compose file |
docker-compose up -d | run a docker-compose file in the background |
docker-compose ls | to list the images inside the docker-compose |
docker-compose start | start a docker-compose container |
docker-compose run | run application of docker-compose file |
docker-compose rm | remove the docker container from the docker-compose |
docker-compose ps | check container status from docker-compose |
