## Profiles
|
||||
|
||||
A profile is the shape of the cluster: how many nodes, which addons, whether the
|
||||
apiserver audits. They live in `ctrl/env.d/`, and the active one is `PROFILE`.
|
||||
**rig needs no profile.** With none named it runs on built-in defaults: one node,
|
||||
no addons, a local registry, the newest Kubernetes version it pins. A profile is
|
||||
an optional overlay — a file in `ctrl/env.d/`, named by `PROFILE` — for when you
|
||||
want a different shape.

rig ships **examples**, not active profiles, because each one is a use case rather
|

than something every rig needs. Copy one to use it:

| `minimal` | the default. One node, no addons, boots fast. |
|

| `client` | the regulated-estate shape — multi-node, audit on, registry mirror. |
|
||||
| `offline` | air-gapped: everything from a preloaded local registry. |
|
||||
| `data` | the cabinets an environment asks for. |

| `client.env.example` | multi-node, audit on, images through a mirror of a corporate registry |
|

| `offline.env.example` | air-gapped: everything from a preloaded local registry |

| `data.env.example` | databases and a scheduler: postgres, redis, airflow |
