Docker Documentation. To learn what Docker is, the official Docker Overview is an excellent resource.
# list docker ps -a # list running docker ps --filter status=running # stop all docker stop $(docker ps -a -q) # remove all docker rm $(docker ps -a -q) # remove docker rm [CONTAINER ID] # remove associated data volumes docker rm -v [CONTAINER ID] # logs docker logs [CONTAINER ID] # bash docker exec -it [CONTAINER ID] /bin/bash # shell docker exec -it [CONTAINER ID] sh
You can substitute the container name for the id. e.g.,
docker logs determined_kapitsa
# list docker images # remove image docker rmi [IMAGE ID] # remove dangling images docker rmi $(docker images -q -f dangling=true) # remove all images docker rmi $(docker images -a -q) # save image docker save -o myimage.tar myimage:latest # load image into docker docker load -i myimage.tar
Docker save / load handy for deploying an image build to a server. e.g., copy the image
.tarfile to server using scp and then load it into Docker.
# list docker volume ls # remove volume docker volume rm [VOLUME NAME] # remove all volumes docker volume rm $(docker volume ls -q) # list dangling volumes docker volume ls -f dangling=true # remove dangling volumes (1.13+) docker volume prune
# docker disk usage docker system df # system-wide info docker system info # real time server events docker system events # removes # - all stopped containers # - all networks not used by at least one container # - all dangling images # - all build cache docker system prune
# builds, (re)creates, starts, # and attaches to containers for a service docker-compose up # use detached mode flag (--detach) docker-compose up -d # stops containers and removes containers, # networks, volumes, and images created by up docker-compose down # compose file removed or renamed containers # use --remove-orphans flag to clean it up docker-compose down --remove-orphans # shell access to any container docker-compose exec [SERVICE] sh # using user www-data (82) for Nginx and PHP containers docker-compose exec --user=82 php sh
To build an image, a text file that list instructions required to create the Docker image is needed. This file is called a Dockerfile. Here is an example of a simple Dockerfile for a Nginx web server. The first line,
FROM nginx is the base image that this image will be built upon. Each line containing the RUN, COPY, ADD instruction create a layer that is saved as a delta (to save space). For more info, docs.docker.com/develop/develop-images/dockerfile_best-practices.
# use official nginx image (https://hub.docker.com/_/nginx) # as base layer for the new image FROM nginx # copy files and folders from `website` directory # into `/usr/share/nginx/html/` directory COPY ./website/ /usr/share/nginx/html/ # copy `nginx.conf` file into `/etc/nginx/` directory COPY ./nginx.conf /etc/nginx/nginx.conf
