Get Started with Docker Part 4

Cheat sheet copied from docker docs
# Create a VM (Mac, Win7, Linux)
$ docker-machine create --driver virtualbox myvm1

# Win10
$ docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm1

# View basic information about your node
$ docker-machine env myvm1

# List the nodes in your swarm
$ docker-machine ssh myvm1 "docker node ls"

# Inspect a node
$ docker-machine ssh myvm1 "docker node inspect <node ID>"

# View join token
$ docker-machine ssh myvm1 "docker swarm join-token -q worker"

# Open an SSH session with the VM; type "exit" to end
$ docker-machine ssh myvm1

# View nodes in swarm (while logged on to manager)
$ docker node ls

# Make the worker leave the swarm
$ docker-machine ssh myvm2 "docker swarm leave"

# Make master leave, kill swarm
$ docker-machine ssh myvm1 "docker swarm leave -f"

# list VMs, asterisk shows which VM this shell is talking to
$ docker-machine ls

# Start a VM that is currently not running
$ docker-machine start myvm1

# show environment variables and command for myvm1
$ docker-machine env myvm1

# Mac command to connect shell to myvm1
$ eval $(docker-machine env myvm1)

# Windows command to connect shell to myvm1
& "C:\Program Files\Docker\Docker\Resources\bin\docker-machine.exe" env myvm1 | Invoke-Expression

# Deploy an app; command shell must be set to talk to manager (myvm1), uses local Compose file
$ docker stack deploy -c <file> <app>

# Copy file to node's home dir (only required if you use ssh to connect to manager and deploy the app)
$ docker-machine scp docker-compose.yml myvm1:~

# Deploy an app using ssh (you must have first copied the Compose file to myvm1)
$ docker-machine ssh myvm1 "docker stack deploy -c <file> <app>"

# Disconnect shell from VMs, use native docker
$ eval $(docker-machine env -u)

# Stop all running VMs
$ docker-machine stop $(docker-machine ls -q)

# Delete all VMs and their disk images
$ docker-machine rm $(docker-machine ls -q)
