docker pull hello-world
Run image
docker run hello-world
docker exec -it CONTAINER_NAME sh
# Now you can enter command in the container
List containers
docker ps
List image
docker image ls
# List all available images in your machine.
docker image ls -aq
# list image ids only
Build Image
docker image build -t IMAGE_NAME:BUILD_NUMBER .
# build image based on docker file in Current directory (.)
Stopping container
docker stop CONTAINER_ID
# copy container id from docker ps
docker stop $(docker ps -aq)
# stop all Running containers
Remove container
docker rm CONTAINER_ID
# Delete Specific container
docker rm $(docker ps -aq)
# Remove all container
Restart policy
–restart
no
Do not automatically restart the container. (the default)
on-failure
Restart the container if it exits due to an error, which manifests as a non-zero exit code.
always
Always restart the container if it stops. If it is manually stopped, it is restarted only when Docker daemon restarts or the container itself is manually restarted. (See the second bullet listed in restart policy details)
unless-stopped
Similar to always, except that when the container is stopped (manually or otherwise), it is not restarted even after Docker daemon restarts.
