Install Tekton Pipelines

[Zzt1993]

How do I install on an Aarh (ARM) architecture server

[AlanGreene]

Tekton Pipelines is built for a number of platforms, including linux/arm and linux/arm64, so you should be able to install it the same way as on any other platform by following the installation instructions: https://tekton.dev/docs/pipelines/install/

Are you having a particular problem installing it?

Can you share more details about the environment, the steps you're following, etc.?

My underlying architecture is ARM
K8s is version 1.23.13
I encountered the following error while installing version 0.44.4, which I believe is due to the lack of support for ARM

I tried deploying the latest version again, but the error still persists

In case you're not already aware, v0.44 has been end of life (i.e. no longer supported) since January: https://github.com/tektoncd/pipeline/blob/main/releases.md#v044-lts

Also the latest release (currently v0.62) requires k8s 1.28 or later: https://github.com/tektoncd/pipeline/tree/main?tab=readme-ov-file#required-kubernetes-version

I took a look at the controller image for the latest release and confirmed it was published for the following platforms:

• linux/amd64
• linux/arm/v6
• linux/arm/v7
• linux/arm64
• linux/ppc64le
• linux/s390x

See details

I also confirmed v0.44.4 has published images for the same list of platforms.

@tektoncd/core-maintainers Can you transfer this issue to tektoncd/pipeline please?

@Zzt1993 hopefully the Pipelines maintainers will be able to guide you further in debugging this.

You can stand up a version of Tekton using your local clone's code to the currently configured K8s context (i.e., kubectl config current-context):

ko apply -R -f config/

If you are just want to try out and have fun, check https://github.com/tektoncd/pipeline/blob/main/DEVELOPMENT.md#managing-tekton-objects-using-ko for detail.

This way image will built from source after configuring ko, go...

I tried deploying the latest version again, but the error still persists

But wondring what arm architecture you have. The latest versions with linux/arm/v6, linux/arm/v7, and linux/arm64 should support a wide range of ARM devices.
