Testing

1. Run Capact from main branch:

   make dev-cluster

2. Populate Hub manifests from main branch:

   kubectl -n capact-system port-forward svc/neo4j-neo4j 7687:7687
   APP_JSONPUBLISHADDR=http://$(ipconfig getifaddr en0) go run cmd/populator/main.go register ocf-manifests ../hub-manifests

3. Log in to Capact CLI: https://capact.io/docs/cli/getting-started#first-use

4. Run the following command against cloned hub-manifests in main branch:

   go run cmd/cli/main.go manifest validate --server-side -v ../hub-manifests/**/*.yaml

   • check the output with and without -v / --verbose flag
   • check the output with and without --server-side flag
   • press CTRL+C in the middle of validation to see how it behaves

5. Check out the fixed manifests from PR: Fix manifest lint errors detected by CLI hub-manifests#16

6. Run the populator:

   kubectl -n capact-system port-forward svc/neo4j-neo4j 7687:7687
   APP_JSONPUBLISHADDR=http://$(ipconfig getifaddr en0) go run cmd/populator/main.go register ocf-manifests ../hub-manifests

7. Follow the 3rd step again. Observe no errors in manifests.
