Dealing with secrets in MongoDB helm chart

[eddy_turbox (Edgar H)]

Morning all, hope this is the right forum!

Currently dealing with the creation of several users and after checking the bitnami chart available options, just seen this two:

  #initdbScripts:
  #    initDB.js: |

  ## Existing ConfigMap with custom init scripts
  ##
  # initdbScriptsConfigMap:

However, I’m facing how to hide user passwords away from those scripts and serve them as an environment variable which is provided by a config map. How is that linkage?

      init_db_script.js: |
        use admin

        sample_user={
          user: "sample-user",
          pwd: ???, # How can I link this to a cm envvar incoming from a secret?
          roles: [
              {role: "readWriteAnyDatabase",db:"admin"}]
        }

Is there an easy way to do so? Thanks a lot!

Hello @eddy_turbox
Welcome to the community!!

There are ways when you can set the environment variable with the username and password and let the secrets apply the same variable. A reference for this is support for environment variables · Issue #944 · helm/helm · GitHub

However, would strongly recommend you to to visit Helm community for more assistance.

Let us know if you need any further assistance.

Thanks
