Installation Recommendation on Kubernetes

[Ahmed Attya]

If I need to install Jira and Confluence in Kubernetes, 
should I have to install them in different namespaces, or I can do it in single namespace

and what is best practice or mandatory for this 

and if I install in one namespace, any consequences or issues?

Hello @Nikola Perisic 

thanks but my questions is not how to install on kubernetes.

I am asking must i install Jira and Confluence in separate namespaces like attlassian-jira and attlassian-confluence or I can install both of them in a single namespace called attlassian for example ?

Hello @Ahmed Attya 

Since namespaces are for segregating resources in the same cluster, are you saying you intend to install Jira DC and Confluence DC in the same cluster?

[Ahmed Attya]

Hello @David Bakkers 

No same cluster but different namespaces, but for some constrains I have to install them on same namespace, so is it applicable or it will create issues in the future ?

[David Bakkers]

Sorry, but can I just double-check what you are saying.

So, irrespective of whether they are in the same namespace or different namespaces, you intend to run Jira DC in one node in a cluster and Confluence DC in another node in the same cluster?

Is that correct?

[Ahmed Attya]

yes different nodes but this is not the problem,  the problem in different namespaces in the same cluster.
as you know Jira and Confluence needs shared-home between them. but for our constrains in our environment we cannot do this if we install jira in namespace-1 and confluence in namespace-2 because pvc is namespaced scope and cannot use same pvc in different namespaces in cluster. and we cannot use NFS for example

so can i install both of them in a single namespace in same cluster ?

[David Bakkers]

Sorry, I can be of no further assistance, as I've never heard of anyone actually doing what you say you are intending to do.

Good luck on your quest.

[Ahmed Attya]

thanks, but you mean that it is recommended to be on different namespaces on cluster?

That is not true.

Deploying each datacenter product to a different namespace is a common practice but not a requirement, so it's up to you.
