Is this feature request related to a problem?

None

Problem Description

I want to create a proper instance of gitlab with both data and db volumes besides the default, at least on db I did find the config to dry that one.

spec:
  database: 
    storage: 
      size: 21Gi

but checking the code for the operator/src/main/kotlin/eu/glasskube/operator/apps/gitlab/dependent/GitlabVolume.kt
,seems to be picking default without allowing change,

            resources {
                requests = mapOf(
                    "storage" to Quantity("20", "Gi")
                )

I did find some similar feature covered over : https://github.com/glasskube/operator/pull/510

i will check to try to make the changes but I not a kotlin guy whatsoever so I will appreciated if someone can take a look after some PR.

Solution Description

We need to create the changes to this files I imagine:

• operator/src/main/kotlin/eu/glasskube/operator/apps/gitlab/dependent/GitlabVolume.kt
• operator/src/main/kotlin/eu/glasskube/operator/apps/gitlab/GitlabSpec.kt

Benefits
