As discussed during standup, you could move the commands into the parent declaration, so they will override the parent's ones

@thepetk I think we discussed this a bit on the call, but do we want to also merge the port update changes with your branch? #26 will help with https://issues.redhat.com/browse/DEVHAS-423

@maysunfaisal I've added the update of the port from 8081 to 8080

Has this change be tested on ODC, odo and HAS to ensure the port update won't cause any regression?

@yangcao77 I think is a good idea to test all new versions on those consumers :)

@thepetk Since we only have one version for all samples currently, any change to samples will directly affect all consumers. plus no ci tests running for samples neither. so it's a requirement to test out before any sample update.

@yangcao77 yup totally agree. One question I have is if we need to update the contributing here https://github.com/devfile/registry/blob/main/CONTRIBUTING.md#samples to include those checks too?

Finally just to clarify, atm all the new version PRs will be merged on different branches than main not known to our consumers. This ofc will change once we update registry's extraDevfileEntries.yaml to support multiple sample versions.

@maysunfaisal port is now 8080 for the new sample version. Feel free to review!
