    I dont think there are any official step-by-step guides other than the installation and configuration guides.
    If there are it would be nice to know about.

    What environment are you running k8s on?

    Hi @IMEX Support / @Kasper Rasmussen ,

    We are trying to install Exstream CE 24.2. We are using below command

    helm install "exstream" "Path of exstream-24.2.16-55862.tgz" --wait --timeout 30m0s --set otds.bootstrap.license.enabled=true --set-file otds.bootstrap.license.nonprod="Path of lic file"  -f "Path of yaml file" --debug

    This installation is getting stopped after a 30 min timeout. Below are debug logs -

    Please suggest if anything is wrong here. We are trying to use Auto Schema Management

    My intuition would be to look at the database connection.
    If you are able to access and if you have permissions. Are you using the internal exstreamdb?
    If you are hard stuck, then try manual schema management.

    Thanks @Kasper Rasmussen for your prompt response! We have checked DB Connection, it is proper. Earlier we have tried using Internal ExstreamDB and no outside DB, that was also getting stucked at same step.

    The above error messages which we mentioned, are with 'No Internal DB' & 'Auto Manage 'true'

    Then we also tried 'No Internal DB' & 'Auto Manage' - 'false' (Manual Schema)

    Here, we are getting stucked with below line -

    ready.go:303: 2024-11-19 13:57:11.3639208 +0530 IST m=+1803.093365301 [debug] Deployment is not ready: default/exstream-batch. 0 out of 1 expected pods are ready

    (In Manual Schema, we have seen only 2 tables added - databasechangelog, databasechangeloglock - Is this normal?)

    The database should contain more than just those two tables.
    So the auto schema mgmt apparently isn't working. When running the Liquibase scripts it will say what it's adding to the database, and it will make a lot of changes :)

    I see you've called your dasdb.externalDb.schema = 'public'. The same for your orcdb.externalDb.schema. You should consider renaming those.

    You'd wanna run the liquibase scripts for each of your schemas (exd_system, exd_tenant, exo_system, exo_tenant)
    add your exd_system and exo_system in this values.yaml and the exd_tenant and exo_tenant in the bootstrap.

    hope that helps

    But also 24.2 has given me some issues, so be aware that the liquibase scripts are run correctly :)
