provider-grafana

provider-grafana is an alternative to the official grafana provider. We encountered scalability issues with the terraform based provider and decided to create a custom provider using the grafana go api client. While we aim to be compatible with the official one, there are some differences in the resources we support:

ProviderConfig differs, as we don't use a json inside a secret but instead fields inside the CRD
Currently only Organization, DataSource, Folder, and Dashboard are supported
Only the oss.grafana.crossplane.io API group is supported

Use this at your own risk!

Migrating from the official provider

Make sure to follow these steps in order, as diverging from them may result in data loss.

Ensure you have backups of your Kubernetes resources and your Grafana database
kubectl delete --wait=false providerconfig.grafana.crossplane.io <name-of-your-provider-config>
kubectl patch providerconfig.grafana.crossplane.io <name-of-your-provider-config> -p '{"metadata":{"finalizers":[]}}' --type=merge
kubectl patch provider.pkg.crossplane.io <name-of-your-provider> -p '{"spec":{"package":"xpkg.upbound.io/argannor-oss/provider-grafana:v0.0.1-9.g4866768"}}' --type=merge
Wait until the provider is up and running before applying the new ProviderConfig (check the example)
Verify that the resources are still there and working as expected

Build

Initially follow these steps:

Run make submodules
Run make reviewable dev

For subsequent builds, just run make dev-redeploy.

Developing

Use this repository as a grafana to create a new one.
Run make submodules to initialize the "build" Make submodule we use for CI/CD.

Rename the provider by running the following command:

  export provider_name=MyProvider # Camel case, e.g. GitHub
  make provider.prepare provider=${provider_name}

Add your new type by running the following command:

  export group=sample # lower case e.g. core, cache, database, storage, etc.
  export type=MyType # Camel casee.g. Bucket, Database, CacheCluster, etc.
  make provider.addtype provider=${provider_name} group=${group} kind=${type}

Replace the sample group with your new group in apis/{provider}.go
Replace the mytype type with your new type in internal/controller/{provider}.go
Replace the default controller and ProviderConfig implementations with your own
Run make reviewable to run code generation, linters, and tests.
Run make build to build the provider.
