Docker Study Note

This post is mainly for my own study reference. Clap for me if you find it useful too!

• docker info
• docker rm $(docker ps -aq)
• docker rm -f $(docker ps -aq)
• docker rmi $(docker images -aq)
• docker run -d --name nginx1 nginx
• docker run -d --name nginx -p 80:80 nginx
• docker diff nginx

• docker container inspect -f “{{json .NetworkSettings.Networks.bridge.IPAddress}}” nginx
• docker container inspect -f “{{json .NetworkSettings.Networks.bridge}}” nginx | python -m json.tool
• docker inspect/start/stop/rm/kill nginx

• docker container/image/system/network prune

• docker run -itd --name php php
• docker run -itd --name alpine alpine
• docker attach alpine
• docker rename alpine newalpine
• docker exec alpine ls
• docker run --name alpine1 alpine ls
• docker run -it --name alpine2 alpine ls
• docker run -it --name alpine3 alpine /bin/sh
• docker ps -a / docker container ls -a
• docker ps / docker container ls
• docker diff nginx
• docker commit alpine alpine:v1
• docker tag <image_id> alpine:v1
• docker build -t hello:v1 .
• docker push hello:v1
• docker ps -af status=exited/running
• docker image history alpine
• docker image inspect — format “{{json .RootFS}}” alpine | python -m json.tool
• docker search centos
• docker run -dP -e Key=”value” --name webserver nginx
• docker exec webserver env
• docker port webserver
• docker run -d --name webserver1 -p 80:80 -v volume:/var/www/html php:7.2-apache
• volume is located at /var/lib/docker/volumes/
• docker plugin install vieux/sshfs --grant-all-permissions
• docker plugin ls
• docker create/inspect volume
• docker create network mynet
• docker network ls
• docker create --name myweb --network mynet -p 80:80 nginx
• docker start myweb
• docker run -d --name myweb1--network mynet -P nginx
• docker network connect/disconnect mynet centos
• docker run -itd --name mycentos --network mynet centos
• docker create network -d overlay mynet
• docker run -d --name myweb --network host nginx
• for host network, -p is ignore since container will use host server network. Port used by service running in container will map directly to host server port

• inspect network to see what containers are connected to the network

• docker swarm init
• docker swarm join --token SWXXXXX 172.31.4.84:2377
• docker swarm join-token manager
• docker node ls

• docker service inspect --pretty myswarm
• docker service ls
• docker service scale myswarm=5
• docker node ps
• docker service rm myswarm
• docker node update --availability drain manager
• docker node promote worker_node
• docker node rm node_name
• docker swarm leave
