Seems a bug, although it's seems a rookie mistake. I will look up into ASAP. Sorry for your inconvenient

[hangyan]

Usually the url of a chart in the index yaml only contains the part path part, but according to helm doc, urls starts with https/http are also supported, this case is not in our test suite. I will add a fix very quickly today

[hangyan]

@bluven Can you try https://github.com/alauda/captain/releases/tag/v0.9.7 ? you can just edit the deploy yaml to update image

[bluven]

Got this problem:

Error from server (InternalError): error when creating "mysql-operator-release.yaml": Internal error occurred: failed calling webhook "mutate-helmrequest.app.alauda.io": Post https://captain-webhook.captain-system.svc:443/mutate?timeout=30s: x509: certificate signed by unknown authority

[hangyan]

Sorry for the later response. This seems a cluster issue. Some other users has also encountered this issue. One solution is to redeploy the cluster, but it obvious not a ideal solution. I will look up into it to find out why

[hangyan]

A temp solution is to delete the mutating and validating webook

Just tested today and relative URL's not supported at version v1.0.1 of Captain:

[hangyan]

Seems like your chart name is nginx-ingress:0.30.0, usally the name does not contains version. How do you generated you repo index.yaml?

[lewismarshall]

@hangyan I can confirm this works when I specify the version at a separate tag but only after building our chart repo with the full URL's in the url field.

If reletive URLs are not supported an error about that would be nice.
