I think you missed updating the workflow that actually builds the containers for the target:

fluent-bit/.github/workflows/call-build-images.yaml

Lines 80 to 92 in 96a88df

	call-build-single-arch-container-images:
	# Allow us to continue to create a manifest if we want
	continue-on-error: true
	permissions:
	contents: read
	packages: write
	strategy:
	fail-fast: false
	matrix:
	platform:
	- amd64
	- arm64
	- arm/v7

It also looks like some Monkey changes which I think need to go via the upstream project @leonardo-albertovich ?

@patrick-stephens The (new) custom_calyptia.sh test is crashing after appearing hanged for a few minutes. Is there something I am missing, or do I need to debug it?

The test is this one I think you mean: https://github.com/fluent/fluent-bit/blob/master/tests/runtime_shell/custom_calyptia.sh

It is using YAML config as well so make sure that's enabled but it should be.

If CALYPTIA_FLEET_TOKEN is not set it will skip (or should do) if that's what you mean.

If I set CALYPTIA_FLEET_TOKEN to a random value the test fails, and if I set it to blank the test hangs and eventually crashes. The test passes on an Intel VM.

@patrick-stephens This is what the test prints on Intel. Is it expected, or is it a bug:

[patrick-stephens]

It looks like it is not skipping it for some reason when the variable is not set, or have you set it to the empty value?
