We have completed✅ the Docker hands-on and I hope you have learned something interesting from it.🙌
Now it's time to take your Docker skills to the next level by creating a comprehensive cheat-sheet of all the commands you've learned so far. This cheat-sheet should include commands for both Docker and Docker-Compose, as well as brief explanations of their usage. This cheat-sheet will not only help you in the future but also contribute to the DevOps community by providing a useful resource for others.
Here's a comprehensive Docker cheat sheet that covers various Docker commands and concepts
Docker Basics:
Images: Templates that contain the filesystem and configuration needed to run a container.
docker images: List all available images.docker pull <image_name>:<tag>: Download an image from a repository.docker rmi <image_name>:<tag>: Remove an image.
Containers: Instances of Docker images running as isolated processes.
docker ps: List running containers.docker ps -a: List all containers (including stopped ones).docker run <image_name>:<tag>: Create and start a new container.docker start <container_id>: Start a stopped container.docker stop <container_id>: Stop a running container.docker rm <container_id>: Remove a container.
Dockerfile: Text file with instructions to build a Docker image.
FROM <base_image>
RUN <command>
COPY <src> <dest>
WORKDIR <directory>
EXPOSE <port>
CMD <command>
Docker Compose: Tool for defining and running multi-container applications.
docker-compose up: Start containers defined indocker-compose.yml.docker-compose down: Stop and remove containers.docker-compose up -d: Start the container in detach modedocker-compose stop:Stop container started by docker-compose updocker-compose ps:List container defined in a docker-compose.ymldocker-compose logs:View all logs defined in a docker-compose.yml
Docker Networking:
docker network ls: List all networks.docker network create <network_name>: Create a new network.docker network connect <network_name> <container_name>: Connect a container to a network.docker network disconnect <network_name> <container_name>: Disconnect a container from a network.
Docker Volumes:
Volumes: Persistent data storage that can be shared between containers and the host.
docker volume ls: List all volumes.docker volume create <volume_name>: Create a new volume.docker run -v <volume_name>:<container_path>: Mount a volume into a container.
Docker Registry:
Docker Hub: A public registry for Docker images.
docker login: Log in to a Docker registry.docker push <image_name>:<tag>: Upload an image to a registry.
Docker Management:
docker logs <container_id>: View logs of a container.docker exec -it <container_id> <command>: Execute a command inside a running container.docker inspect <container_id>: View detailed information about a container.docker stats: Display live performance data for all containers.
Docker Cleanup:
docker system prune: Remove all unused images, containers, networks, and volumes.docker system prune -a: Remove all images, containers, networks, and volumes.
Remember that this cheat sheet provides only a quick overview of Docker commands and concepts. For more in-depth information and usage details, refer to the official Docker documentation.
Happy Learning!
