Howto handle infinispan cache creating and deployment

[barash]

We have a infinispan cluster serving as cache server for our applications. Every time we need a new cache, we have to edit the config files, and redeploy the cluster, which is problematic. For obvious reasons, we don't want to redeploy the cache cluster. We can add the new cache definition through web interface, or cli. But it has downside of not recording this configuration in a repo. Ideally I want to be able to add cache definitions in a way that is persistent in my code repo. So that in case of a disaster, I can simply redeploy the cache cluster.

We looked into creating cache definition through the source code, at application startup, but that doesn't seems to be possible.

Does anyone has an idea about the best practises for this issue?

When you make changes through the CLI / Console, they are persisted to the standalone.xml/domain.xml, so you could version that.

Yes, but how? It is not easy to create a straight forward workflow. Either I have to tell developers to *remember* to do that, which we know how that goes. Or I have to setup a watch to commit the  changes to git, which is going to create a snowflake server. I cannot think of a good way of doing that.

Ideally, I want to be able to do cache creation through Ansible, for example. Or maybe programmatically at app boot time, a bash script to be called by Ansible. I want to know if there are any options around these lines.

I was hoping to be able to do it via a rest call to the console, but it seems it doesn't exist either.

So why not use the CLI ?

/subsystem=datagrid-infinispan/cache-container=clustered/distributed-cache=mynewcache:add(configuration=dist-cache-template)

That is nice actually, still I would love to see ansible integration

Just as a reference for the CLI (which we inherit from the WildFly server base) look at some recipes:

The DMR (the server internal configuration model) can also be configured over HTTP:
