[bitnami/mlflow] Request -> support for MySQL in MLFlow about charts

[javsalgar]

Hi!

Thank you so much for the feature request. I will forward this to the team for evaluation.

For the time being, it is possible for you to integrate it with an existing mysql installation by setting postgresql.enabled=false and overriding the command and args sections (see command and args under tracking) to set the configuration to use your own mysql database.

Thanks for the suggestion and I will use the custom command to setup MySQL for now.

I tried this and got pretty far by hacking on the helm chart.
For example the helpers are very opinionated about postgres and I had to modify the URIs to be able to change the driver/protocol:
https://github.com/bitnami/charts/blob/main/bitnami/mlflow/templates/_helpers.tpl#L495

- {{- printf "postgresql://%s:$(MLFLOW_DATABASE_PASSWORD)@%s:%v/%s" (include "mlflow.v0.database.user" .) (include "mlflow.v0.database.host" .) (include "mlflow.v0.database.port" .) (include "mlflow.v0.database-auth.name" .) -}}
+ {{- printf "%s://%s:$(MLFLOW_DATABASE_PASSWORD)@%s:%v/%s" (include "mlflow.v0.database.protocol" .) (include "mlflow.v0.database.user" .) (include "mlflow.v0.database.host" .) (include "mlflow.v0.database.port" .) (include "mlflow.v0.database-auth.name" .) -}}

However, the base image for mlflow would need to have additional system and/or pip dependencies installed to support this.

For example: I set protocol to mysql+pymysql trying to deal with an error similar to ImportError: No module named MySQLdb. https://stackoverflow.com/questions/22252397/importerror-no-module-named-mysqldb. Any chance of there being an image we can use with those dependencies installed? I'd be happy to make a PR if so. https://bitnami.com/stack/mlflow/containers says I'd probably need to add that here? a PR to here https://github.com/bitnami/containers/blob/main/bitnami/mlflow/2/debian-12/Dockerfile ?

Hi!

I forwarded this to the team to see if we can add the module to the container.
