Servers

Servers are split into different roles, with each role having its own configuration.

For simpler deployments, though, where all servers are identical, you can just specify a list of servers. They will be implicitly assigned to the web role.

servers:
  - 172.0.0.1
  - 172.0.0.2
  - 172.0.0.3

Tagging servers

Servers can be tagged, with the tags used to add custom env variables (see Environment variables).

servers:
  - 172.0.0.1
  - 172.0.0.2: experiments
  - 172.0.0.3: [ experiments, three ]

Roles

For more complex deployments (e.g., if you are running job hosts), you can specify roles and configure each separately (see Roles):

servers:
  web:
    ...
  workers:
    ...
