exec user process caused: exec format error

[tekumara]

Expected Behavior

Automatically detect my cluster's arch and build the correct image for it.

Current Behavior

          api │ Attaching to existing pod (api-76dfc675cd-7zlcm). Only new logs will be streamed.
          api │ WARNING: Detected container restart. Pod: api-76dfc675cd-7zlcm. Container: deployer.
          api │ standard_init_linux.go:228: exec user process caused: exec format error

Steps to Reproduce

1. Run tilt up on a mac m1 arm64 against an amd64 cluster

About Your Use Case

For some reason tilt is building the arm64 image rather than detecting my cluster arch and building an amd64 image.

[tekumara]

For now I'm using docker_build( ..., platform='linux/amd64') and it works!

The Container Runtime: read-failure is suspicious. That usually means that your cluster admin is denying you permission to read info about the cluster nodes (which includes both container runtime and processor arch).

Can you run tilt get clusters -o yaml against a running tilt session and post the output?

[nicks]

But yeah, setting the platform manually is the best workaround if your admin is denying permission to read the arch off the cluster.

[tekumara]

Sure!
