How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Renovate 37.326.3 using npx in a AzureDevOps build agent

Please tell us more about your question or problem

I'm trying to have renovate manage a dependency which is a versioned .zip file that I retrieve using curl in a Dockerfile:

# renovate: depName=glowroot
ENV GLOWROOT_VERSION=0.10.12

RUN curl -kLO https://github.com/glowroot/glowroot/releases/download/v${GLOWROOT_VERSION}/glowroot-${GLOWROOT_VERSION}-dist.zip

I'm using the following regex config to retrieve versioning information via a custom datasource using the Github API and let renovate use that:

"customManagers": [
        {
            "customType": "regex",
            "fileMatch": ["^Dockerfile$"],
            "matchStrings": ["depName=(?<depName>.*?)\\sENV .*?_VERSION=(?<currentValue>.*)\\s"],
            "versioningTemplate": "semver-coerced",
            "datasourceTemplate": "custom.glowroot"
        }
],
"customDatasources": {
    "glowroot": {
        "defaultRegistryUrlTemplate": "https://api.github.com/repos/glowroot/glowroot/tags",
        "transformTemplates": ["{\"releases\":[{\"version\": ($.name)[0]}]"]
    }
}

However I get connection errors shown in the log below using custom.glowroot as the datasourceTemplate reference. Alternatively, when I'm using glowroot as datasourceTemplate reference I get invalid-config errors.

Logs (if relevant)

I'd recommend you use the github-tags or github-releases datasource as a custom one should not be necessary here.

That works! Thanks for the quick response.
