Also, i double checked, chartmuseum-endpoint works correctly and available from concourse container

[headcr4sh]

I think, I encountered a similar error in the past if the URL of my ChartMuseum instance pointed to a wrong / misconfigured host. Just to rule that one out: could you please check if "http://chartmuseum-chartmuseum.infra:8080/" reachable from your Concourse CI worker instance?

# Step 1

yep, Chartmuseum endpoint looks good

Ok. So it's most definitely a bug within the resource. :-( Thanks for veryfying.

[metacoma]

BTW, i tested against

/chartmuseum --version
ChartMuseum version 0.2.7 (build 3650311)

[headcr4sh]

Mh. Latest version of ChartMuseum is 0.7.1... maybe you try upgrading? ;-) (but I doubt that's gonna change anything)

[metacoma]

I updated ChartMuseum up to 0.7.1 and got a strange behavior

for now, my pipeline fails with:

An error occured while uploading the chart: "not found".

ChartMuseum logs:

Sorry, it's my first experience with ChartMuseum, maybe i miss some steps to initialize or something like that?

[metacoma]

Hey @headcr4sh

I installed ChartMuseum from stable/chartmuseum helm chart By default (sic!), this chart installs ChartMuseum with disabled API! https://github.com/helm/charts/blob/master/stable/chartmuseum/values.yaml#L64

After enabling API, cocnourse-chartmuseum-resource works fine

Thanks for the support!

[headcr4sh]

Oh man... ... the error message of the resource is really misleading, then. I'll have to improve on that.

[Sluggerman]

For us, it was force keyword since allow-overwrite was disabled in Chartmuseum.
