Knoci

Knoci (/'nəʊki/ Know-Key) is an operator that adds a test resource to kubernetes clusters. This allows you to turn build && test && deploy into build && deploy, with your pods only coming online after their relevant tests have passed.

Benefits

1. You can run your tests anywhere you could run a cluster. This makes it possible to exactly reproduce what happens in a CI pipeline locally
2. Tests can be completely parallelized, using the same autoscaling logic you'd use for pods (see example/parallelism)
3. Knoci checksums your tests, and only runs ones whose files or dependencies have changed

Usage

Installing the Operator

See deploy/in/knoci.yaml.tmpl for an RBAC example
