Ginuudan

Comes to measure the containers of code, and cause it to dwindle

Etymology: Supposedly a spirit from local filipino mythology.

Kubernetes Jobs do not complete unless every container within the Pod has been terminated. In an attempt to solve this, Ginuudan observes Pods with the annotation ginuudan.nais.io/dwindle set to "true". When the Pod's main application completed, Ginuudan goes through each of the Pod's sidecars to shut them down.

Sidecars that Ginuudan can handle

• linkerd-proxy - runs in GCP
• cloudsql-proxy - runs if your app provisions databases through spec.gcp.sqlInstances
• secure-logs-fluentd - runs if your app has spec.secureLogs.enabled set to true
• secure-logs-configmap-reload - runs if your app has spec.secureLogs.enabled set to true
• vks-sidecar - runs if your app has spec.vault.sidecar set to true
