kustom-spilo-postgres

Kustomize-enabled manifests for deploying zalando/spilo HA PostgreSQL clusters into Kubernetes.

Usage

Create a kustomization.yaml file in your own repo. Here's an example:

bases:
  - git::ssh://[email protected]/hagmonk/kustom-spilo-postgres
  
commonLabels:
  cluster-name: mini

Ensure that environment variables SUPERUSER_PASSWORD and REPLICATION_PASSWORD are set when running the kustomize build command:

env SUPERUSER_PASSWORD=hovercraft REPLICATION_PASSWORD=eels kustomize build

This should product valid YAML that can be piped directly to kubectl apply -f -

Configuration

Kustomize has excellent documentation and examples, but here are some ideas to get you started for overriding config.

The underlying Spilo image is configured through environment variables, which are documented here for Patroni and here for Spilo.

kustomization.yaml

bases:
  - git::ssh://[email protected]/hagmonk/kustom-spilo-postgres

commonLabels:

# Prefix all resource names with this
namePrefix: production-

# Merge new environment variables in
configMapGenerator:
- name: postgres
  behavior: merge
  literals: 
    - PGUSER_ADMIN=lord-foobar

# Tweak the statefulset for replicas and storage
