Sometimes deploying Docker stacks can be a pain. What if they didn't have to be?

Reduce those really long commands into files you can make once and change easily. Be lazy.

With Lazy Docker, you only need to run ./DockerMachine.py --help or ./DockerContainer.py --help to see how to use it.

Lazy Docker is written for Python 3. This is usually not the default Python environment, so you'll need to be sure python3 is installed. Also, if you want to run these files directly, be sure and run chmod +x DockerMachine.py DockerContainer.py in this directory.

To start something like Consul, you could run something like:

./DockerContainer.py create consul_test consul:server

Say you want to run multiple Docker Machines with Consul on each one (with all of its slightly confusing configuration). First, let's set up a Docker Hub mirror.

./DockerMachine.py create --no-registry-mirror registry
./DockerContainer.py --machine registry registry_container registry:mirror

Done! Now we've got a mirror for when all of our other machines want to download something. Each of those --command type arguments have single letter aliases as well.

Now onto creating Consul's machines.

./DockerMachine.py create docker1
./DockerContainer.py -m docker1 create consul consul:first

Now in the config file (inside conf.d) called consul_server.json, change the command portion where it joins some kind of {{consul}} to the name of your machine we just made, in {{braces}}. (i.e. {{docker1}})

Now run these:

./DockerMachine.py create docker2
./DockerContainer.py -m docker1 create consul consul:server

Now you have two Consul machines with a Consul container on each.

The configurations and default arguments in this CLI are very opinionated but should be fairly easy to change. Take a look either in the config files or the respective Python file you're using (towards the bottom of the files).

If you're curious, devious, or all of the above, just run export UTILS_DEBUG=true in your command line. (To undo that, use unset UTILS_DEBUG)

Now run any command you want to test out! All of the commands should actually just print out the docker/docker-machine commands it would have run normally.

This is definitely in alpha. Feel free to use it, but don't expect it to work 100%!
