fleet

Leveraging Docker Engine's built-in Swarm Mode on Ubuntu Server LTS Virtual Machines. This is the first piece of code that should be executed against a fresh host on the diesel.net domain

Checking-In New Hosts

To add a new host (or set of hosts) create a new local branch name with the pattern check-in/*, add the new hosts and their configuration to the inventory, then push. Please delete your check-in/* branch after merging.

Bootstrapping Hosts

Pushes to stable branches will trigger the entire fleet to be bootstrapped.

Updating Hosts

You will need the following installed:

Python 3.11+
