Error when trying to Install Argo Events on OpenShift (cannot use port 443)

[stratus-ss]

Describe the bug
This bug report is exactly the same as #1726

The user closed the bug without specifying a solution. Myself and a second user are interested in this fix/solution as well but I fear bumping a closed ticket will not receive any attention and I cannot reopen the old ticket.

How do we get the webhook to listen on a different port? Do we have to recompile the application? The namespace is an env variable but the port is not. Ideally this would be set to 8443 as an alternative

Thanks!

The error for reference is

how are you isntalling argo events? we are using it on openshift and installed it via the community helm-chart. the option "openshift: true" it should work out of the box.

Anybody wants to submit a PR to make the port configurable (e.g. in the args)?

[nirsht]

Hi @whynowy, I can do it

I might have missed the helm chart option. Looking back in my history I see I definitely used the kubectl apply method.
I want to say that I also tried the helm installation as well but this box's history has rolled over since then but if I did, I missed the option that I see is present (when I know to look for it)

@nirsht thank you for volunteering to make a PR. I am sure I won't be the last person to focus on applying the yamls instead of using the helm chart!

Hi @stratus-ss, the port is indeed not configurable either way, if only the port would be configurable it would help. I made PR #2215 with option to configure the port, while setting the default to 443. If the PR looks good to you, I will update the docs also.

[stratus-ss]

@nirsht this was exactly the direction I thought would be available. I found the environment variable for namespace while i was trying to see if there was a setting for the port.

much appreciated

@nirsht - thank you! PR merged, will be available in next release.
