Configuration of the minio PVC size from the global values.yaml

[bouleq]

Hi everyone, I am using Magda as a data catalog, and I encountered this issue:

I am storing my data directly in Magda (not in an external storage), but the minio's PVC size is only 10Go by default.
I thought I could configure it from the global values.yaml but it doesn't seem to be possible, so I had to change the value in the packaged chart in magda/charts/magda-core/charts/storage-api/values.yaml.

I think it could be nice to add the possibility to configure this parameter directly in the global values.yaml

Helm allows you to pass down the values to sub chart (and sub chart's subchart) with
Therefore, you don't have to modify the storage API default value file --- storage-api/values.yaml file to overwrite the minio config (the document is here: https://github.com/magda-io/magda/blob/master/deploy/helm/internal-charts/storage-api/README.md).

Instead, you can (depends on your chart hierarchy):

• if you deploy magda chart directly, you can put the following in the values file that you supply via helm upgrade / install -f switch:

magda-core:
  storage-api:
    minio:
      persistence:
        size: 123G

• if you use a deployment wrapper chart and declare magda chart as one of the dependencies, you can put the following in the values file that you supply via helm upgrade / install -f switch:

magda:
  magda-core:
    storage-api:
      minio:
        persistence:
          size: 123G

• if you use a deployment wrapper chart and declare magda-core chart as one of the dependencies, you can put the following in the values file that you supply via helm upgrade / install -f switch:

magda-core:
  storage-api:
    minio:
      persistence:
        size: 123G

If you have troubles of making values flowing through, you can use --debug to print out helm runtime computation values for debug:

helm upgrade --debug --dry-run --install --timeout 9999s -f [my config value files] [deployment name] [chart name] > output.yaml
