[Migration] chart: timescaledb-single. Migrating secrets as per v0.10.0 upgrade guide fails: templates/secret-certificate.yaml: unable to parse YAML: error converting YAML to JSON: yaml: line 2: did not find expected node content

Have a look at Troubleshooting or some Common Issues

Describe the bug

Empty secret templates such as service-patroni.yaml prevent helm from successfully completing the templates rendering when following k8s secrets migration from v0.10.0 upgrade guide.

Changes:

• Deleted: Secrets provided via Kustomize.
• Added: secrets.credentialsSecretName: "foobar-credentials" (+ 2 credentials params)

To Reproduce Both commands fail with the same error (the 1st command being the most important as it prevents proper chart deployment: we do helm template ... and then kubectl apply ...)

Note: foobar-timescaledb-timescaledb-single-original is simply the original chart folder name being renamed by a script on my end.

Command 1:

helm template foobar-timescaledb-timescaledb-single-original --values foobar-timescaledb-timescaledb-single-custom/values.yaml --name-template foobar --output-dir foobar-timescaledb-timescaledb-single-final/

Command 2:

helm lint foobar-timescaledb-timescaledb-single-original --values foobar-timescaledb-timescaledb-single-custom/values.yaml

Expected behavior Template rendering to not fail for this configuration.

Deployment

• Chart: timescaledb-single
• values.yaml: See bug description section.
• Chart: 0.10.0
• k8s: 1.20.x

Deployment None, the template rendering fails on a local machine, without ever needing to talk to the k8s cluster.

@feikesteenbergen @thedodd Pinging you guys :-)

This should've been fixed in latest helm chart release after https://github.com/timescale/helm-charts/pull/327 was merged. If you find that the problem is still happening in your environment, please reopen this ticket.
