Docker 学习记录笔记（一）

Docker 一些简单的命令列表
docker build -t friendlyhello . # Create image using this directory's Dockerfile
docker run -p 4000:80 friendlyhello # Run "friendlyname" mapping port 4000 to 80
docker run -d -p 4000:80 friendlyhello # Same thing, but in detached mode
docker container ls # List all running containers
docker run -d --net=my_bridge --name db training/postgres（image名称） #运行一个容器并绑定到my_bridge网络，若没有指定网络则为默认bridge网络 名字为db，
docker container ls -a # List all containers, even those not running
docker container stop <hash> # Gracefully stop the specified container
docker container kill <hash> # Force shutdown of the specified container
docker container rm <hash> # Remove specified container from this machine
docker container rm $(docker container ls -a -q) # Remove all containers
docker image ls -a # List all images on this machine
docker image rm <image id> # Remove specified image from this machine
docker image rm $(docker image ls -a -q) # Remove all images from this machine
docker login # Log in this CLI session using your Docker credentials
docker tag <image> username/repository:tag # Tag <image> for upload to registry
docker push username/repository:tag # Upload tagged image to registry
docker run username/repository:tag # Run image from a registry

docker stack ls # List stacks or apps
docker stack deploy -c <composefile> <appname> # Run the specified Compose file
docker service ls # List running services associated with an app
docker service ps <service> # List tasks associated with an app
docker inspect <task or container> # Inspect task or container
docker container ls -q # List container IDs
docker stack rm <appname> # Tear down an application
docker swarm leave --force # Take down a single node swarm from the manager

docker-machine create --driver virtualbox myvm1 # Create a VM (Mac, Win7, Linux)
docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm1 # Win10
docker-machine env myvm1 # View basic information about your node
docker-machine ssh myvm1 "docker node ls" # List the nodes in your swarm
docker-machine ssh myvm1 "docker node inspect <node ID>" # Inspect a node
docker-machine ssh myvm1 "docker swarm join-token -q worker" # View join token
docker-machine ssh myvm1 # Open an SSH session with the VM; type "exit" to end
docker node ls # View nodes in swarm (while logged on to manager)
docker-machine ssh myvm2 "docker swarm leave" # Make the worker leave the swarm
docker-machine ssh myvm1 "docker swarm leave -f" # Make master leave, kill swarm
docker-machine ls # list VMs, asterisk shows which VM this shell is talking to
docker-machine start myvm1 # Start a VM that is currently not running
docker-machine env myvm1 # show environment variables and command for myvm1
eval $(docker-machine env myvm1) # Mac command to connect shell to myvm1
& "C:\Program Files\Docker\Docker\Resources\bin\docker-machine.exe" env myvm1 | Invoke-Expression # Windows command to connect shell to myvm1
docker stack deploy -c <file> <app> # Deploy an app; command shell must be set to talk to manager (myvm1), uses local Compose file
docker-machine scp docker-compose.yml myvm1:~ # Copy file to node's home dir (only required if you use ssh to connect to manager and deploy the app)
docker-machine ssh myvm1 "docker stack deploy -c <file> <app>" # Deploy an app using ssh (you must have first copied the Compose file to myvm1)
eval $(docker-machine env -u) # Disconnect shell from VMs, use native docker
docker-machine stop $(docker-machine ls -q) # Stop all running VMs
docker-machine rm $(docker-machine ls -q) # Delete all VMs and their disk images

docker network ls #查看网络
NETWORK ID NAME DRIVER
18a2866682b8 none null
c288470c46f6 host host
7b369448dccb bridge bridge
#三个默认网络

docker network inspect bridge（网络名称） #检查网络，可以看到所包含的容器
docker network disconnect bridge networktest #断开网络，可以通过断开容器从网络中移除容器。为此，提供网络名称和容器名称。也可以使用容器ID。

docker network create -d bridge（驱动为默认bridge） my_bridge（网络名称） #创建网络

docker inspect --format='{{json .NetworkSettings.Networks}}' db # 查看容器db的网络信息
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' web #查看容器web的IP地址
docker exec -it db bash #链接容器进入shell，ping web(容器名称而不是容器ip)
docker network connect my_bridge web #将web容器连入my_bridge网络，以便可更网络内其他容器通信，

使用docker-compose 时，注意一下版本对应，不然会报错
