Not able to deploy 2 TC server in different namespaces #54

Closed thomas-2020 closed 4 months ago

thomas-2020 commented 4 months ago

I have created a TC server with Helm Chart terracottabigmemorymax in first namespace, e.g. tc-01. If I create a second TC server in namespace tc-02, the first in tc-01 is crashed.

@thomas-2020 : what do you mean by "namespaces" ? You mean the release namespace passed to helm instal or the overrides in the values.yaml file or --namespace ?

How our chars work:

These settings below have NO EFFECT except on defining config map names. Server names and hostnames ARE NOT dependent of any of that, because we want:

  1. the server names and hostnames to not change because security configs, keystores, etc depend on these names
  2. tc cluster, to be deployed ISOLATED in its OWN Release Namespace
# -- The namespace where the Terracotta cluster will be deployed.
namespaceOverride: ""
# -- Overwrites Chart name of release name in workload name. As default, the workload name is release name + '-' + Chart name. The workload name is at the end release name + '-' + value of `nameOverride`.
nameOverride: ""
# -- Overwrites full workload name. As default, the workload name is release name + '-' + Chart name.
fullnameOverride: ""

If I understand correctly you tried to deploy 2 clusters in the same release name but trying to override some of these settings to hopefully change the server names right ?

Why ?

K8s already provides a way to separate deployment units per release namespace.

Do you have a need to deploy in the same release namespace 2 tc clusters ? and if so, why ?

FYI:

Do ...

helm upgrade --install tc-default webmethods/terracottabigmemorymax -f tc-ahip.yaml -n dev
helm upgrade --install tc-default webmethods/terracottabigmemorymax -f tc-ahip.yaml -n qas

TC in namespace dev was successfully deployed. On installing TC in qas, devis crashed.

So it works.

I cannot test with the official images because I cannot login:
