mariadb-operator VS vault-secrets-operator

Once you have learnt the basics I would recommend you to contribute to an open source operator like mariadb-operator: https://github.com/mariadb-operator/mariadb-operator

In this blog, we discuss the effective utilization of mariadb-operator to manage MariaDB instances in Kubernetes using CRDS, promoting a declarative approach instead of relying on imperative commands.

v0.0.16 release: https://github.com/mariadb-operator/mariadb-operator/releases/tag/v0.0.16

Refer to the documentation for further detail: https://github.com/mariadb-operator/mariadb-operator/blob/main/docs/GALERA.md

I think I've managed to reproduce your issue using podman rootless KIND, but it does not have to do with Podman at all. It was some RBAC misconfiguration in the last version of the Helm chart that caused the controller to be unable to watch some resources on the Kubernetes API. I've released a v0.0.3 to fix this.

I'm quite happy to announce that, after months of work, I'm releasing today the second alpha version of mariadb-operator, a Kubernetes operator written in Go that enables you to run and operate MariaDB in a cloud native way. Forget about imperative commands, do everything declaratively using CRDs.

I've created an issue for this: https://github.com/mmontes11/mariadb-operator/issues/10

For home use, I wouldn't bother with Vault unless that's really what you want to learn. Then it's worth looking into setting something up where you could use vault secrets, using one of the available options (I haven't seen the vault-secrets-operator being mentioned).

It is but it affects vault-secrets-operator too, see https://github.com/ricoberger/vault-secrets-operator/issues/104 (and no, I’ve only use vault-secrets-operator)

If you are using an external KMS in any case, then there are other options, such as the kubernetes-external-secrets operator that was originally started by GoDaddy and the externalsecret-operator from Container Solutions. If you use HashiCorp Vault, you also have the option of using the Vault Secrets operator. This works similarly to the Sealed Secrets Operator, but instead of managing its own key material, it retrieves the secrets from Vault. The CNCF Technology Radar from January 2021 provides an overview of the types of tools that are available for secrets management.
