@spartanns, there have been multiple inconsistencies across the app regarding the r/o mode. Are these all the changes we need?

[spartanns]

Basically, if a cluster is read only, then ALL the broker config edit functionality is disabled. Meaning nothing in broker config can be edited in cluster RO mode.

[Haarolean]

there have been issues across the app as I mentioned in #230, so the purpose of that issue is to fix these discrepancies across the whole app

[spartanns]

I tested my changes with 2 clusters in the app. One was read only the other one was not... You can take a look in this video:

In case I missed something, let me know and I'll fix it.

[Haarolean]

Once again -- the issue is not just about broker configs, it's about all the possible buttons in all the places.
For instance, in a r/o cluster restart/remove connectors options are available (they shouldn't be):

We have to check for all these things.

[spartanns]

Ahhh, okay, I didn't know that...I'll get right on it, and I'll let you know once I'm done.

[spartanns]

Okay, so I disabled the ActionsCell in connectors table in cluster RO mode:

Broker config edits are disabled as well as all topic configs. Connector creation is also disabled in RO mode.

If there's anything else, just let me know ;p

[Haarolean]

@spartanns sorry for the delay. I've left one comment and there's a merge conflict, once these are done we're good to merge!

[Haarolean]

@spartanns thanks for your first PR! Sorry for the delay.
