Runtime created step-export can't find Dockerfile when using private repository

At e.g. Python 3.7 runtime Dockerfile is written to /workspace/workspace/$(inputs.params.DIRECTORY) at dockerfilestep, and referred just as --dockerfile=Dockerfile at export step.

This causes Kaniko to look Dockerfile from /kaniko/Dockerfile when registry-secret argument is defined. This produces error:

Error: error resolving dockerfile path: copying dockerfile: creating file: open /kaniko/Dockerfile: permission denied

to logs.

Workaround seems to be to use - --dockerfile=/workspace/workspace/$(inputs.params.DIRECTORY)/Dockerfile in export step. According to Kaniko documentation Dockerfile should be using context as a base, but apparently that's not the case (even with Kaniko 1.2.0) when registry-secret is defined.

@Hi-Fi hi and thanks for the report. I walked through all deployment examples from our readme and they worked perfectly fine for me - kaniko's context parameter does its job (at least at v0.8.0). Could you share some information about your environment, such as which kubernetes platform and version, knative version, and if you're using tm CLI. Also would be helpful if you run python example commands with debugging enabled (tm -d ...) and dump the output here in a comment. Thanks!

@Hi-Fi one more important bit - if you use tm CLI, please make sure that you're on the latest stable version
https://github.com/triggermesh/tm/releases/latest

Just noticed that it happens only if I define registry-secret to command.

Error: error resolving dockerfile path: copying dockerfile: open /kaniko/Dockerfile: permission denied

I'd say that it's kaniko permission issue (missing root privileges) if it happens not only when registry-secret is set.

Just noticed that it happens only if I define registry-secret to command

Could you elaborate on what happens without the registry-secret parameter?

I run Kaniko as privileged and as UID 0, so I don't think it's permission issue. The Dockerfile is never written to /kaniko, so I don't see how it can be ever found from there. And as said, if that registry-secret is not set, things work as you also mentioned.

Task tries to push to that default knative.registry.svc.cluster.local, and fails as it's not found. So task works fine against default registry at least.

I still don't see how setting the registry secret could break the export step in such an uninformative way. Could you show what taskrun pod looks like?

Tested this a bit more, and it got interesting:
When auth is created with single word in project, it works:
tm set registry-auth --registry private.interlnal.registry --project demo test

But when project has slashes, that error with Dockerfile comes (and things only work when Dockerfile if given with full path):
tm set registry-auth --registry private.interlnal.registry --project demo/with/paths test2

Edit:
When I generate secret with backslashes
tm set registry-auth --registry private.interlnal.registry --project demo\/with\/paths test3 things seem to be working fine, even the secrets are equal.

Probably this is Kaniko issue, as that command just generates the secret?

set registry-auth command creates dockerconfigjson type of secret, mounts it into the taskrun build pod, sets DOCKER_CONFIG env variable, and updates SA's image pull secret. Also, the registry and the project is used in kaniko's destination parameter, and according to the describe pod output slashes are all fine:

--destination=PRIVATE.SERVER.URL/klr-poc/images/python-test:furPRD

I still cannot reproduce the issue even if I use project value with the slashes but I noticed that my test environment is few versions behind (tekton, k8s), so maybe there were some changes in related components. I'll update the cluster, run some more tests and get back to you.

Just figured this out, and it was my own fault. We have runasuser-admission-controller in use, and it puts securityContext to pod level, which prevents Kaniko to work. Maybe backslashed version worked because that controller pod was down or something.

But disabling the controller for namespace made things work. Sorry for extra work caused.

I'm glad we figured it out, because updating the cluster components didn't change anything, and I had no other ideas.
