Cannot build Mariner 2 iso with Ubuntu 18.04/arm64v8 container

[cwyborny]

Trying to build basic arm iso. Build fails with "ERRO[0000] env variable CHROOT_DIR not defined" after packages are added to chroot. Full build output attached.

From the logs I could notice Host rpm version 4.14.1 while Guest has 4.18.0.
Can you try to please update rpm tools.
Also, I would request you to once run a sudo make clean.

[cwyborny]

I was unable to update the rpm tools as the latest version in the container version, Ubuntu 18.04 is 4.14.1. I saw that error and it seems related to sqlite but I'm not sure exactly what it means. Attached is another build output after make clean. Failure looks slightly different but still about $CHROOT.

Investigating further seems like this is a test that is breaking and thus preventing forward progress.
Could you please give complete details of how are you running this:

• Are you trying in a VM or docker conntainer ?

Reference:
[exibit - a]: This is getting called from a test

[exibit - b]: This specific test fails IMO

[cwyborny]

Yes, the container mentioned in the title (arm64v8/ubuntu:18.04) is a Docker container. I tried manually creating that env variable with what it looked like the location should be in the Makefile - $BUILD_DIR/worker/chroot, but there was another failure that wasn't as obvious and I thought there was more broken than just a missing variable. I can provide that output if it would be helpful.

What additional info can I provide or what do you suggest I try?

[cwyborny]

As an additional note, I'm also building Mariner in a Docker Ubuntu 18.04 x86 container and have the same issue. Any info on what might need to be configured or changed in my enviroment is much appreciated.

[cwyborny]

Also, I'm using regular build commands in my Docker container, not anything special for "Docker based pipeline." If the build commands or process is different from a regular native build, that may be the issue. I will investigate the build documentation for Docker specific information.

[mfrw]

I think the commands that you are using are specific for a VM build.
Can you please try to build in a VM instead of a container.

The container has a slightly different handling of the chroots. The docs are w.r.t to a build in the VM.

I need to cross build arm64 on a x86 system. Rachel Menge provided a document for this using a Docker container on Mariner 1.0, but I need to generate a Mariner 2.0 image. https://github.com/rlmenge/cblmarinerdemo-cross-build I have been using this document but adjusting for 2.0, maybe I missed something. Can I get assistance with building in a container?

[cwyborny]

Also, I don't believe the documents clearly state that the commands are only for building in a VM.

/cc @rlmenge

[cwyborny]

I see the container link above has been updated since the document I was provided. I will try these steps and report the results.

[cwyborny]

Unfortunately this fails too on add-apt-repo RUN command in the Dockerfile. Although even if it worked, its still creating an environment for Mariner 1.0 and I need to build a Mariner 2.0 image. I will see if I can make some minor mods to get it working.

[cwyborny]

So, I updated the files in the link above for 2.0-stable and it fails in the same place eventually with the same test failures and CHROOT_DIR error. Although the changes I made are the same ones I made doing a manual container build for 2.0, so I may have made the same configuration errors or omissions.

Just some context here, this repo was created in to spin up an ARM container on x86 machines to enable building ARM images locally because CBL-Mariner only builds on native architecture. It is designed to work on 18.04 Ubuntu for CBL-Mariner 1.0 and is not officially supported.

That being said, all it does is

1. Dockerfile installs the latest set of prereqs
2. The configure_buildenv runs the tutorial steps to prepare the environment to build Mariner. (Note there was a name change from CBL-MarinerDemo to CBL-MarinerTutorials)
