Custom Configuration Section

As Nomad loads the configuration from files and directories in lexical order, typically merging on top of previously parsed configuration files, you may set custom configurations via nomad_config_custom, which will be expanded into a file named custom.json within your nomad_config_dir which will be loaded after all other configuration by default.

An example usage for enabling vault:

  vars:
    nomad_config_custom:
      vault:
        enabled          : true
        ca_path          : "/etc/certs/ca"
        cert_file        : "/var/certs/vault.crt"
        key_file         : "/var/certs/vault.key"
        address          : "https://vault.service.consul:8200"
        create_from_role : "nomad-cluster"

Dependencies

Ansible requires GNU tar and this role performs some local use of the unarchive module, so ensure that your system has gtar/unzip installed. Jinja2 templates use ipaddr filter that need netaddr python library.

Example Playbook

Basic nomad installation is possible using the included site.yml playbook:

ansible-playbook -i <hosts> site.yml

You can also simply pass variables in using the --extra-vars option to the ansible-playbook command:

ansible-playbook -i hosts site.yml --extra-vars "nomad_datacenter=maui"

Vagrant and VirtualBox

See examples/README_VAGRANT.md for details on quick Vagrant deployments under VirtualBox for testing, etc.
