Resolver Template

This directory contains a working Resolver based on the instructions from the developer howto in the docs.

This Resolver responds to type demo.

Parameters

Name Desccription Example Value
url The repository url. https://example.com/repo/

Using the template to start a new Resolver

You can use this as a template to quickly get a new Resolver up and running with your own preferred storage backend.

To reuse the template, simply copy this entire subdirectory to a new directory. The entire program is defined in ./cmd/demoresolver/main.go and provides stub implementations of all the methods defined by the framework.Resolver interface.

Once copied you'll need to run go mod init and go mod tidy at the root of your project. We don't need this in tektoncd/resolution because this submodule relies on the go.mod and go.sum defined at the root of the repo.

After your go module is initialized and dependencies tidied, update config/demo-resolver-deployment.yaml. The image field of the container will need to point to your new go module's name, with a ko:// prefix.

Deploying the Resolver

Requirements
Install
  1. Install the "demo" Resolver:
$ ko apply -f ./config/demo-resolver-deployment.yaml
Testing

Try creating a ResolutionRequest targeting "demo" with no parameters:

$ cat <<EOF > rrtest.yaml
apiVersion: resolution.tekton.dev/v1beta1
kind: ResolutionRequest
metadata:
  name: test-resolver-template
  labels:
    resolution.tekton.dev/type: demo
EOF

$ kubectl apply -f ./rrtest.yaml

$ kubectl get resolutionrequest -w test-resolver-template

You should shortly see the ResolutionRequest succeed and the content of a hello-world Pipeline base64-encoded in the object's status.data field.

Example PipelineRun

Here's an example PipelineRun that uses the hard-coded demo Pipeline:

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: resolver-demo
spec:
  pipelineRef:
    resolver: demo

What's Supported?

  • Just one hard-coded Pipeline for demonstration purposes.
