Difficulty pushing image to remote docker repo

[jspruance]

Hello! I am attempting to use the buildpacks Tekton task to clone a Github repo, build the image and then push it to my public repo on Docker Hub. Everything seems to be working until the last step.

The error info in the pod logs isn't super helpful:
State: Terminated
Reason: Error
Message: [{"key":"StartedAt","value":"2022-11-23T16:49:29.261Z","type":3}]
Exit Code: 1
Started: Wed, 23 Nov 2022 08:49:25 -0800
Finished: Wed, 23 Nov 2022 08:49:35 -0800

One thing I am questioning is whether I am setting the Docker Hub repo url correctly. After reading the documentation I believe that is what the 'APP_IMAGE' var should reflect. Is that correct?

From docs:
APP_IMAGE: The name of where to store the app image. (REQUIRED)

My Docker Hub repo:
https://hub.docker.com/repository/docker/jspruancedome/ocean-api

^^ This is the same value I am setting for 'APP_IMAGE'.

The repo doesn't currently contain any images - the one that buildpacks is pushing would be the first image.

Does all of this sound correct? I am pretty new to Tekton, Buildpacks and Kubernetes and trying to ramp up on all of these things but may have a few gaps in my knowledge still. Thanks for any help.

Hi @jspruance and welcome to the Buildpacks community. The docs for our Tekton task describe https://buildpacks.io/docs/tools/tekton/#43-pipeline as the pipeline definition. Which takes an input image name and passes it as APP_IMAGE to the Buildpacks task. The PipleineRun passes the image name as a parameter:

params:
    - name: image
      value: <REGISTRY/IMAGE NAME, eg gcr.io/test/image > 

Could you share your Pipeline and PipelineRun definitions?

Thanks for the reply.

I created a git repo for my working poc...

My PipelineRun definition is in the 'triggers.yaml' file here:
https://github.com/jspruance/build-pipeline-poc/blob/main/docs/getting-started/triggers.yaml

Pipeline definition is here:
https://github.com/tektoncd/triggers/blob/main/docs/getting-started/pipeline.yaml

I believe I have the image name passed in as you described but not sure if I have the format correct (was unsure if it should literally be the name or the repo url):

params: - name: image value: hub.docker.com/repository/docker/jspruancedome/ocean-api

Just to add - it is failing on the 'create' step. Is there any way to get more detailed error messaging so I can see what went wrong?

Update: I got this working after changing the 'image' value to just the image / tag instead of the URL of the image:

params:
          - name: image
            value: jspruancedome/ocean-api:dome

I think the documentation around this is a bit confusing as the example makes it seem like this should be a URL not an image name:

params:
    - name: image
      value: <REGISTRY/IMAGE NAME, eg gcr.io/test/image >
      

Thanks for the help.
