Tekton Pipelines for Instana Go Tracer

Tekton Setup on a Cluster

  • You need access to a cluster with full admin privileges.
  • Allocate enough RAM and CPU so that all the pods, including sidecar pods, will run smoothly on a single node.
  • Add multiple nodes to increase parallel pipeline runs.

Tekton Setup

# Install Tekton pipelines
kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

# Install Tekton triggers
kubectl apply --filename https://storage.googleapis.com/tekton-releases/triggers/latest/release.yaml

# Install Tekton interceptors
kubectl apply --filename https://storage.googleapis.com/tekton-releases/triggers/latest/interceptors.yaml

# Install Tekton dashboard - full installation is needed for read/write capabilities. eg: to make changes in the pipeline, such as re-running a pipeline run or deleting a pipeline run.
kubectl apply --filename https://storage.googleapis.com/tekton-releases/dashboard/latest/release-full.yaml

# Make sure all pods are in the ready state before proceeding further by issuing the following command.
kubectl get pods --namespace tekton-pipelines --watch

# To access the dashboard in localhost
kubectl proxy
  • If you have successfully completed the above mentioned steps, you should be able to access the Tekton Dashboard from here

Pipelines present in Go Tracer

  • Individual pipelines can be found in their respective directories here. You will find detailed usage instructions in a README file within each directory.

    1. CI Build
    2. Tracer Reports

Deleting old pipeline run resources

  • Deletion of old pipeline run resources will be automatically handled by a cron job by default. You can review the configuration in cleanup-cron-job.yaml. Feel free to edit the NUM_TO_KEEP variable to specify the number of old pipeline runs you wish to retain. The default value is 50.
