Hub Resolver

Use resolver type hub.

Parameters

Param Name	Description	Example Value
catalog	The catalog from where to pull the resource (Optional)	Default: Tekton
kind	Either task or pipeline	task
name	The name of the task or pipeline to fetch from the hub	golang-build
version	Version of task or pipeline to pull in from hub. Wrap the number in quotes!	"0.5"

Getting Started

Requirements

See the getting started instructions in the Tekton Resolution repo.

Install

1. Install the Hub resolver:

$ ko apply -f ./config

Configuring the Hub API endpoint

By default this resolver will hit the public hub api at https://hub.tekton.dev/ but you can configure your own (for example to use a private hub instance) by setting the HUB_API environment variable in config/hubresolver-deployment.yaml. Example:

env
- name: HUB_API
  value: "https://api.hub.tekton.dev/"

Testing it out

Try creating a ResolutionRequest for a hub entry:

$ cat <<EOF > rrtest.yaml
apiVersion: resolution.tekton.dev/v1alpha1
kind: ResolutionRequest
metadata:
  name: fetch-hub-entry
  labels:
    resolution.tekton.dev/type: hub
spec:
  params:
    kind: task
    name: git-clone
    version: "0.5"
    kind: task
EOF

$ kubectl apply -f ./rrtest.yaml

$ kubectl get resolutionrequest -w fetch-hub-entry

You should shortly see the ResolutionRequest succeed and the content of the git-clone yaml base64-encoded in the object's status.data field.

Example PipelineRun

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: hub-demo
spec:
  pipelineRef:
    resolver: hub
    resource:
    - name: catalog # optional
      value: Tekton 
    - name: kind
      value: pipeline
    - name: name
      value: buildpacks
    - name: version
      value: "0.1"
  # Note: the buildpacks pipeline requires parameters.
  # Resolution of the pipeline will succeed but the PipelineRun
  # overall will not succeed without those parameters.
