Helm

Infrastructure integration · 12 node(s).

00Overview

Install, upgrade, roll back and uninstall Helm releases on your cluster from a flow, and inspect what is already deployed — list releases, read their status and history, and render or lint a chart before it goes anywhere near the cluster. Pair it with the Kubernetes nodes to build a full release pipeline.

Every field below is exactly what you see in the Flomation editor. Fields marked ● live picker let you choose from a list pulled live from your account — no IDs to look up.

01Connecting Helm

  1. Helm talks to the same cluster as the Kubernetes nodes and takes the same credentials — set up the API Server URL and Authentication exactly as described on the Kubernetes page. The service account will need permission to manage the resources the chart creates, and to read and write secrets in the release's namespace (that is where Helm records its release history).
  2. The nodes that change or render a release — Install, Upgrade, Rollback, Uninstall, Test, Template, Lint and Show — run the helm command, so it has to be available to the Flomation runner. The runner takes it from Helm Binary Path if you set one, otherwise from the helm on its PATH; failing both it downloads a pinned release and verifies its checksum before running it (set Helm Version to pin a different one). On a locked-down or air-gapped runner your administrator can pre-install helm on the host instead — see the installation guide. The read-only nodes — List Releases, Get Release, Release Status and Release History — talk to the cluster directly and need no helm command at all.
  3. For a chart from a public repository, put the repository in Repository URL (e.g. https://charts.bitnami.com/bitnami) and the chart's name in Chart. You can also give Chart an OCI reference (oci://ghcr.io/org/chart) or a direct .tgz URL and leave the repository blank.
  4. For a private chart repository, fill in Repository Username and Repository Password, storing the password as an environment secret. If the repository sits behind an internal certificate authority, paste that CA into Repository CA Certificate (PEM).
  5. Pin Chart Version on anything you care about — left blank, an install picks up whatever the repository currently calls latest, which is rarely what you want in a repeatable flow.

Pick an Environment on your flow (Flow Settings → Environment) so the secret resolves. Secret fields never show the value — they reference ${secrets.your_secret}.
