Helm Install

Installation

The Pipekit Agent must be installed onto each cluster where your Argo Workflow controller runs.

Helm Install

When you choose to connect a cluster in Pipekit, you will be provided with a Secret Access Key for the cluster and a unique Cluster ID. These need to be passed to the helm chart when installing the Pipekit Agent. You should store the Secret Access Key securely in a password manager or similar.

kubectl create ns argo
helm repo add pipekit https://helm.pipekit.io

helm upgrade -i -n argo \
pipekit-agent pipekit/pipekit-agent \
--set secrets.pipekitSecretAccessKey="[provided Secret Access Key]" \
--set secrets.pipekitClusterId="[provided Cluster ID]"

Argo CD

If you are using Argo CD, you can install the Pipekit Agent using the following steps:

Create and push a secret to your cluster containing your pipekitSecretAccessKey and pipekitClusterId
Create a new Argo CD Application Manifest, referencing that secret:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: pipekit-agent
namespace: argocd
finalizers:
    - resources-finalizer.argocd.argoproj.io
spec:
destination:
    namespace: argo
    server: 'https://kubernetes.default.svc'
  source:
    repoURL: 'https://helm.pipekit.io'
    chart: pipekit-agent
    targetRevision: HEAD
    helm:
      parameters:
        - name: secrets.existingSecret
          value: "pipekit-agent"
project: default
syncPolicy:
    automated:
    prune: true
    selfHeal: true
    syncOptions:
    - PrunePropagationPolicy=background
    - CreateNamespace=true

Argo CD offers other secrets management alternatives to ensure that your secrets are not stored in plaintext in your git repository. You can read more about them here.

kubectl -n argo create secret generic pipekit-agent \
    --from-literal=PIPEKIT_SECRET_ACCESS_KEY='abc123' \
    --from-literal=PIPEKIT_CLUSTER_ID='123abc'

You must use single quotes '' to escape special characters such as $, , *, =, and ! in your strings. If you don't, your shell will interpret these characters.

Enabling Externally Triggered Workflows

If you wish to enable externally triggered workflows, you can set the following values in your Helm install command:

kubectl create ns argo
helm repo add pipekit https://helm.pipekit.io

helm upgrade -i -n argo \
pipekit-agent pipekit/pipekit-agent \
--set secrets.pipekitSecretAccessKey="[provided Secret Access Key]" \
--set secrets.pipekitClusterId="[provided Cluster ID]" \
--set configMap.allowExternalWorkflows=true

You can additionally set configMap.externalWorkflowsCheckPeriod, configMap.externalWorkflowsNamespace and configMap.shouldDeleteExternalWorkflows. Refer to the values table above for more information.

Pipekit Agent Cluster Permissions

The Pipekit Agent needs to interact with Argo Workflows on your cluster. In order to do this, we create a ServiceAccount and ClusterRole for the Pipekit Agent. If you wish to manually manage this ServiceAccount and ClusterRole, you can set serviceAccount.create to false and provide the name of an existing ServiceAccount to use.

The required minimum permissions are:

  - apiGroups:
      - argoproj.io
    resources:
      - clusterworkflowtemplates
      - workflows
      - cronworkflows
      - workflowtemplates
    verbs:
      - create
      - delete
      - get
      - list
      - patch
      - update
      - watch

Upgrading Pipekit Agent

Checking the latest version

Pipekit Agent is automatically published to Artifact Hub. You can use this service to configure automatic notifications of new versions, either via an RSS feed or a webhook.

Alternatively, you can search the helm repo for the latest version of the Pipekit Agent using the following command:

# Add the repo if you don't already have it.
helm repo add pipekit https://helm.pipekit.io
helm repo update
helm search repo pipekit/pipekit-agent --versions

For further information on the helm search repo command, please refer to the official Helm documentation.

Changes to the default values.yaml

Prior to upgrading, you should ensure that you understand any changes to the default values.yaml and the impact those changes may have on your installation. This page is always updated with the latest available helm chart values for the Pipekit Agent.

If you wish to upgrade to an older version of the Pipekit Agent helm chart, you can extract the default values for that version using the following command:

helm show values pipekit/pipekit-agent --version [version]

The Pipekit-Agent values file is commented so you can see what each value does.

You can extract your existing values from your current installation using the following command:

helm get values pipekit-agent -n argo

For further information the helm commands used above, please refer to the official Helm documentation.

Upgrading the Pipekit Agent

To upgrade the Pipekit Agent, you can use the following command:

helm upgrade pipekit-agent pipekit/pipekit-agent \
--set secrets.pipekitSecretAccessKey="[provided Secret Access Key]" \
--set secrets.pipekitClusterId="[provided Cluster ID]" \
-n argo

For more information on using Helm to perform upgrades, please check the official Helm documentation.

Automating the upgrades using Gitops

If you use a Gitops tool such as Argo CD, you can simply commit your changes to your git repository and the tool will handle the Helm upgrade for you.

If you wish to automate the upgrade process, we recommend a third party tool called Renovate Bot that can be configured to automatically raise pull requests for you when a new version of the Pipekit Agent is released.

Upgrade Support

If you have an issue upgrading your Pipekit Agent that isn't addressed here, please contact us over Slack, or by email at support@pipekit.io.
