API: support search by repo URL

[brsolomon-deloitte]

I see that /repositories/search takes a name but not a url. Is it possible to search by URL to locate a repository and its metadata?

For example:

• I have https://charts.bitnami.com/bitnami as URL
• I want to be able to /repositories/search with url=https://charts.bitnami.com/bitnami and see in result that the repo is bitnami
• and then execute /packages/helm/bitnami/keycloak

Hi @brsolomon-deloitte 👋

This could be a nice addition, we'll look into it 👍

Thanks!

@tegioz is there any multi-step workaround you can think of, even it is a little messy? (Perhaps even with helm or something else?)

I am having a surprisingly tough time just doing a map-lookup of the repo name from its url.

[brsolomon-deloitte]

For some background, we are looking to create a "Helm Dependabot" that will periodically scan for possible Helm chart version updates. It currently has the repo URL and current version (and can easily grab it via yq) but not the repo name itself in Chart.yaml.

Maybe the endpoint below can be of help 🙂

https://artifacthub.io/docs/api/#/Integrations/getHelmExporterDump

It was created for a tool with a similar purpose actually. It'll give you a short summary of all repositories, that includes the url for a fast local lookup.

Hope it helps.

Nice, here's what I put together (could also just pipe curl to jq):

$ curl -fsSL \
  -o helm-export.json \
  'https://artifacthub.io/api/v1/helm-exporter' \
  -H 'accept: application/json'
$ jq -M '.[] | select(.repository.url == "https://charts.bitnami.com/bitnami" and .name == "keycloak")' helm-export.json 
{
  "name": "keycloak",
  "version": "6.1.4",
  "repository": {
    "name": "bitnami",
    "url": "https://charts.bitnami.com/bitnami"
  }
}
