Custom Workload Profile Charts
What are Custom Workload Profile Charts?
This article is about how to create and register Workload Profile Charts to make them available for use in Custom Workload Profiles .
Prepare a Helm Chart
A chart version represents a specific version of a Helm chart and can be created by either uploading a locally packaged chart tar -czf "example-profile.tgz" ./example-profile or a chart downloaded from a Helm chart registry helm pull chart.
Humanitec will extract the following properties from the Chart.yaml:
namewill become theidof your Workload Profile chart version.versionwill become theversionof the Workload Profile chart version. Each version needs to be a valid semver identifier and can only be used once. If you add another version, the new version needs to be >= all existing versions.
Visit the api-docs for the complete schema.
Internally the provided charts will be used with a mechanism comparable to helm template and the same restrictions apply:
Any values that would normally be looked up or retrieved in-cluster will be faked locally. Additionally, none of the server-side testing of chart validity (e.g. whether an API is supported) is done.
Register the Chart
You can create a Workload Profile chart version as follows:
Assuming you have a chart archive file chart.tgz inside the current directory:
curl "https://api.humanitec.io/orgs/${HUMANITEC_ORG}/workload-profile-chart-versions" \
-X POST \
-H "Authorization: Bearer $HUMANITEC_TOKEN" \
-F "[email protected]"
Where the following environment variables are set:
| Variable | Example | Description |
