Tekton PipelineRun workspace not found

What is Tekton PipelineRun workspace not found

Understanding Tekton and Its Purpose

Tekton is an open-source framework for creating CI/CD systems. It provides Kubernetes-style resources for declaring CI/CD-style pipelines. Tekton allows developers to build, test, and deploy across cloud providers and on-premise systems. By leveraging Kubernetes, Tekton offers a cloud-native way to manage and execute pipelines.

Identifying the Symptom: PipelineRun Workspace Not Found

When working with Tekton, you might encounter an error message stating: PipelineRun workspace not found. This error typically occurs when a workspace specified in a PipelineRun is not properly defined or bound, leading to execution failures.

Common Observations

The PipelineRun fails to start or execute. Error logs indicate missing workspace bindings. Tasks within the pipeline cannot access necessary resources.

Exploring the Issue: Missing Workspace in PipelineRun

The error arises when a PipelineRun is configured to use a workspace that hasn't been defined or bound correctly. Workspaces in Tekton are used to share data between tasks and persist data across pipeline executions. If a workspace is not properly set up, tasks that rely on it will fail to execute.

Root Cause Analysis

The root cause of this issue is typically a misconfiguration in the PipelineRun specification. This can happen if:

The workspace is not declared in the Pipeline or PipelineRun spec. The workspace is declared but not bound to a volume or PVC (Persistent Volume Claim). There is a typo or mismatch in the workspace name between the Pipeline and PipelineRun.

Steps to Resolve the PipelineRun Workspace Issue

To resolve the PipelineRun workspace not found error, follow these steps:

Step 1: Verify Workspace Declaration

Ensure that the workspace is declared in both the Pipeline and PipelineRun specifications. Check for any typos or mismatches in the workspace names.

apiVersion: tekton.dev/v1beta1kind: Pipelinemetadata: name: example-pipelinespec: workspaces: - name: shared-workspace tasks: - name: example-task workspaces: - name: shared-workspace

Step 2: Bind the Workspace in PipelineRun

Ensure that the PipelineRun binds the workspace to a valid volume or PVC. This binding allows the workspace to be used during the pipeline execution.

apiVersion: tekton.dev/v1beta1kind: PipelineRunmetadata: name: example-pipelinerunspec: pipelineRef: name: example-pipeline workspaces: - name: shared-workspace persistentVolumeClaim: claimName: my-pvc

Step 3: Validate the Configuration

After making changes, validate your configuration by applying the updated Pipeline and PipelineRun resources. Use the following command:

kubectl apply -f pipeline.yamlkubectl apply -f pipelinerun.yaml
