NixOS Docker Swarm Node Configuration

WIP

Personnal NixOS configuration for a docker swarm node

Configures:

• Users
• GlusterFS
• Docker
• Auto-upgrades

Steps:

1. Create a CA certificate/key pair for your GlusterFS cluster, place the certificate as ./certs/glusterfs.ca in each node.
2. Use the CA to create certficates for each node, and add them as ./certs/glusterfs.pem and ./certs/glusterfs.key in the corresponding nodes.
3. Edit the node-config.nix files with your values.
4. Apply the nix configuration
5. Setup the GlusterFS pools and volumes (see https://docs.gluster.org/en/latest/)
6. Setup Docker Swarm
