Docker Container
Docker Basics
- To know currently Running docker version
docker --version
- To get detailed information about docker installation
docker info
Working with Containers
- to run a docker container
# docker run [options] image-name [command] [args]
# ex.
docker run -d nginx
- to list running containers
docker ps
- to list all the containers running or stopped
docker ps -a
- to stop a running stop
# docker stop [container_id/name]
docker stop nginx
- to start a stopped container
# docker start [container_id/name]
docker start nginx
- to restart a container
# docker restart [container_id/name]
docker restart nginx
- to remove a stopped container
# docker rm [container_id/name]
docker rm nginx
- to check logs of a container
# docker logs [container_id/name]
docker logs nginx
Docker images
- to list all the docker images
docker images
- to download an image from docker hub
# docker pull [image_name]
docker pull nginx
- to build an image from a docker file
# docker build -t [IMAGE_NAME:TAG]
docker build -t
- to remove an docker image
# docker rmi [IMAGE_NAME:TAG
docker rmi nignx
Docker volume
- to create a docker volumes
# docker volume create [VOLUME_NAME]
docker volume create [VOLUME_NAME]
- to list all the volumes
docker volume ls
- to remove a volume
docker volume rm [VOLUME_NAME]
Docker networking
- to list all the docker networks
docker network ls
- to create docker network
docker network create [NETWORK_NAME]
- to connect a container to a specific docker network
docker network connect [NETWORK_NAME]
- view details about specific docker network
docker network inspect [NETWORK_NAME]
Docker Compose
- start all the service defined in a yaml file
docker-compose up
- stop and remove all servies defined in the file
docker-compose down
- list all services managed by compose
docker-compose ps
Debugging and monitoring
- run a command inside a running container
docker exec -it [container_id/name]
- View detailed information about a container or image
docker inspect [container_id/name]
- monitor resource usage of container
docker stats
Clean up
- remove unused data(stopped container, images, networks)
docker system prune
- remove unwanted containers
docker container prune
- remove unused images
docker image prune
- remove unused volume
docker volume prune
