issue #22 deployment config

[domiborges]

• Add additional helm commands to the install procedure
• Add description of the server configuration values
• Add a values file with the default configuration

@oraNod few questions A values file with all the configuration values or something lighter? WDYT? If the changes are OK I'd update the dowstream content in a similar way. I just wanted to check it with you first. I'm looking for a better place to include the reference module with the server configuration. Cache Manager TBD

@ryanemerson I've reworked this to copy the default server configuration for the deploy.infinispan section. This was the original plan and then point to the server guide for specific examples. I'd prefer to keep that approach as it will avoid us having too many config snippets in the helm chart docs repo, which presents a maintenance headache. Please take another look when you get a chance.

@dvagnero If the server configuration examples are OK, and they should be, I think all that is left with this PR is to make sure the procedure to disable authorization is correct. Ryan is going to make some changes tomorrow to enable security authz by default so users will need to know how to disable it. I did add a procedure but we should review it with Ryan after he makes the change tomorrow. We can then squash the commits and merge. :wind_chime:

@oraNod It turns out that I was telling you wrong ... Authorization is currently enabled by default. In order to disable authorization you need to set deploy.infinispan.cacheContainer.security=null whereas the default config sets ...security.authorization=null.

Even so, I will update values.yaml to use an empty element:

  infinispan:
    cacheContainer:
      security:
        authorization: {}

As that's slightly more intuitive than null.

It's looking good @oraNod @dvagnero!

Can you update the values.yaml in the repo to be the same as the ones in the docs with the [USER] comments?

Just a thought on structure. Should we move section 1.6 to be 2.0 and call this something like "Infinispan Server Configuration"? To me section 1.6 seems a separate topic to the other 1.x sections that are more related to chart lifecycle and initialisation. "Configuring authentication and authorization" could then be a subsection of the server configuration, WDYT?

Thanks @dvagnero and @oraNod
