Namespaces

A namespace is a logical scope for resources. Two services can share a name as long as they're in different namespaces. Tokens, policies, and namespaces themselves live in the special system namespace.

Built-in namespaces

Both are seeded automatically on first server start.

Creating a namespace

rune create namespace prod
rune create namespace staging

Or declaratively:

namespace:
  name: prod
  description: Production workloads

rune cast prod-ns.yaml

Using a namespace

Most commands take -n / --namespace:

rune get services -n prod
rune cast api.yaml -n prod
rune scale api 5 -n prod

Or set a default per context:

rune login prod \
  --server runed.example.com:7863 \
  --token-file ./prod.token \
  --namespace prod

Now rune defaults to prod for that context.

The service.namespace: field in your YAML wins over -n if both are set, so prefer one approach per environment.

Cross-namespace references

Most things are scoped to a single namespace. The exceptions:

• Tokens, users, policies live in system and are global.
• Service dependencies can target other namespaces explicitly:

  dependencies:
    - service: postgres
      namespace: data

Secrets and configmaps cannot be referenced across namespaces. Copy them or use a runeset.

Listing across namespaces

rune get services --all-namespaces

This requires a policy that allows the verb in * namespace.

Listing namespaces

rune get namespaces

Deleting a namespace

rune delete namespace staging

Refuses if the namespace contains resources unless you pass --force (cascade delete).
