AppCat Service PostgreSQL

This service provider installs PostgreSQL instances of various architecture types using the AppCat and Crossplane frameworks.

Local Development

Requirements

• docker
• go
• helm
• kubectl
• yq
• sed (or gsed for Mac)

Some other requirements (e.g. kind) will be compiled on-the-fly and put in the local cache dir .kind as needed.

Common make targets

• make build to build the binary and docker image
• make generate to (re)generate additional code artifacts
• make test run test suite
• make local-install to install the operator in local cluster
• make install-samples to run the provider in local cluster and apply a sample instance
• make run-operator to run the code in operator mode against local cluster

See all targets with make help

QuickStart Demonstration

TL;DR: make local-install install-samples s3-credentials

Running Operator without Webhook server

make local-install -e "local_install_args=--set webhook.enabled=false"

Kubernetes Webhook Troubleshooting

The provider comes with mutating and validation admission webhook server. However, in this setup this currently only works in the kind cluster when installed as package using make package-install.

To test and troubleshoot the webhooks, do a port-forward and send an admission request sample of the spec:

# port-forward webhook server
kubectl -n crossplane-system port-forward $(kubectl -n crossplane-system get pods -o name -l pkg.crossplane.io/provider=appcat-service-postgresql) 9443:9443

# send an admission request
curl -k -v -H "Content-Type: application/json" --data @package/samples/admission.k8s.io_admissionreview.json https://localhost:9443/validate-postgresql-appcat-vshn-io-v1alpha1-postgresqlstandalone
