pack build fails on v0.2.0

[ngatti-tmm]

Hello, today I tried to build my app and failed. When running pack build on a php application I get the following error:

pack build --trust-builder -v ${IMAGE_NAME}:${BITBUCKET_COMMIT} --builder heroku/builder:24 \
    -t ${IMAGE_NAME}:latest --publish --cache-image ${CACHE_IMAGE_NAME}  \
    --buildpack heroku/php --default-process web

The same pack build command worked ok on v0.1.2.

I tried with heroku/builder:22 and heroku/builder:20, and removing --buildpack heroku/php parameter, same error.

Hi! I'm puzzled by this log line:

target distro name/version labels not found, reading /etc/os-release file

It should not be appearing, since:

1. Our images do have those labels set (https://github.com/heroku/base-images/blob/2323b38c808bb4eb555bf5965148f6882b987bd8/heroku-24/Dockerfile#L7-L8)
2. The upstream lifecycle bug that prevented them being picked up was fixed (CNB_TARGET_DISTRO_NAME and CNB_TARGET_DISTRO_VERSION not set correctly in buildpack env buildpacks/lifecycle#1324) and our images are using latest lifecycle that includes that fix

Could you paste the output of running pack report?

[ngatti-tmm]

Sure, here it is:

Pack:
  Version:  0.27.0
  OS/Arch:  linux/amd64
Default Lifecycle Version:  0.14.1
Supported Platform APIs:  0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9
Config:
(no config file found at /root/.pack/config.toml)

I am running pack from a bitbucket runner container.

Here is the full log output of the pack build with --builder heroku/builder:20:

@ngatti-tmm Thank you - that allowed me to reproduce.

The issue is that:

1. You are using a very old Pack CLI version (0.27.0 from June 2022, when 0.34.2 is the latest)
2. The old Pack CLI version doesn't support CNB Platform API 0.10, so runs the build using Platform API 0.9, and there appears to be a lifecycle bug when using that older API version, which I've just reported upstream: CNB_TARGET_ARCH and CNB_TARGET_OS not set correctly when using Platform API 0.9 buildpacks/lifecycle#1371

Once the upstream lifecycle bug is fixed and released in a new version, we will update our builder images to use that new release, eg here:
https://github.com/heroku/cnb-builder-images/blob/786bd787f190de30e8302cc64b4da121d98a4951/builder-24/builder.toml#L8-L9

In the meantime you'll need to update to a newer Pack CLI version - which is worth doing regardless to pick up new features and fixes in the Pack CLI :-)

[ngatti-tmm]

Thank you Ed. I wrongly asumed that the Pack CLI was installed on each pipeline. But it was installed on the base build image and as it wasn't updated.
I updated Pack CLI manually and now deployment worked ok.
Thank you very much for your help.

[edmorley]

No problem! Thank you for reporting the issue - it let me find an upstream bug which would be great to have fixed regardless :-)
