Expected Behavior

I’m doing a test locally following the guide https://tekton.dev/docs/how-to-guides/clone-repository/

I have a git-server running inside a docker container. I’m trying to get tekton to pull the project and display it’s readme.

Actual Behavior

When I run the task this is the error that I see in the logs

task fetch-source has failed: "step-clone" exited with code 1 (image: "gcr.io/tekton-releases/github.com/tektoncd/pipeline/cmd/git-init@sha256:c0b0ed1cd81090ce8eecf60b936e9345089d9dfdb6ebdd2fd7b4a0341ef4f2b9"); for logs run: kubectl -n default logs clone-read-run-cr7dx-fetch-source-pod -c step-clone

Steps to Reproduce the Problem

The files pipeline.yaml and show-readme.yaml are identical to the files in the tutorial. I modified the pipelinerun.yaml slightly to put my repos git url in there

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  generateName: clone-read-run-
spec:
  pipelineRef:
    name: clone-read
  podTemplate:
    securityContext:
      fsGroup: 65532
  workspaces:
  - name: shared-data
    volumeClaimTemplate:
      spec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
  - name: git-credentials
    secret: 
      secretName: git-credentials      
  params:
  - name: repo-url
    value: git@172.17.0.1:apps/701d7256-a8df-44ce-9bc4-5f1cd61257f4.git

my ssh-secret.yaml is as follow ( with my ssh key redacted)

apiVersion: v1
kind: Secret
metadata:
  name: git-credentials
data:
  id_rsa: <REDACTED>
  known_hosts: 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

my ssh config is like this

Steps to reproduce

1. tkn hub install task git-clone
2. kubectl apply -f show-readme.yaml , kubectl apply -f pipeline.yaml and ssh-secret.yaml
3. k create -f pipelinerun.yaml

Then this problem occurs. I am really stumped with this problem can somebody please help me or give me some hints ? I also tried removing the config entirely from ssh-secret.yaml , same error.
