[bitnami/neo4j 2.0] Unable to add single custom configuration in neo4j.conf

[rocketsciencenerd]

Name and Version

bitnami/neo4j 2.0

What architecture are you using?

amd64

What steps will reproduce the bug?

We are using the neo4j community edition which means we can have only one database at a time.

We initially were trying to use a custom db "custom-db" which is set by NEO4J_initial_dbms_default__database: '${NEO4J_DBNAME:-custom-db}' in our docker-compose file locally.

However, when trying to set this same default in the helm chart using terraform like this:

resource "helm_release" "neo4j_db" {
  name       = "neo4j"
  repository = "oci://registry-1.docker.io/bitnamicharts"
  chart      = "neo4j"
  version    = "0.2.0"
  namespace  = local.namespace_name
  
  ...other settings
  
  set {
      name  = "configuration.initial.dbms.default_database"
      value = "custom-db"
  }

Note: the configuration comes from the bitnami "configuration" property and the neo4j.conf configuration initial.dbms.default_database provided by neo4j

The helm chart did not interpret it correctly and gives the following error "No declared setting with name: default_database". Logs below:

It seems like the auto-population of the neo4j.conf file using the "configuration" value is populated using the common.tpvalues.render which is stripping out the "initial.dbms" part of "initial.dbms.default_database".

When investigating the /opt/bitnami/neo4j/conf/neo4j.conf file:

I have no name!@neo4j-develop-std-syqh-0:/opt/bitnami/neo4j/conf$ cat neo4j.conf
#*****************************************************************
# Neo4j configuration
#
# For more details and a complete list of settings, please see
# https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/
#*****************************************************************

# The name of the default database
#initial.dbms.default_database=neo4j

The "initial.dbms.default_database=neo4j" line is visible as part of the default conf file, further confirming that this is the correct configuration value, but there doesn't seem to be a way to set it using the "configuration" value in the helm chart.

Are you using any custom parameters or values?

configuration.initial.dbms.default_database="custom-db"

What is the expected behavior?

Be able to set configuration.initial.dbms.default_database in neo4j.conf file using a helm chart custom parameter.

What do you see instead?

The common.tpvalues.render function seems to be stripping out the "initial.dbms" portion of the configuration string "initial.dbms.default_database"

Which throws this error:

Error: Unrecognized setting. No declared setting with name: default_database. Cleanup the config or disable 'server.config.strict_validation.enabled' to continue.
