Repo tool package_container is not working

[DiegoTorresBZS]

Description

I have transitioned to using IsaacSim because the omni.replicator.core extension in Kit App 109.0.3 requires omni.pip.cloud, a dependency that appears to be exclusive to the IsaacSim bundle.

Since I need the latest version of Replicator (available only in current IsaacSim 6.0.0-dev), I am encountering an issue while building my Docker image. It appears the previous repo tool package no longer supports the --container flag. I am receiving the following error after following this steps:

# Clone the repository with v6.0.0-dev branch
git clone -b v6.0.0-dev https://github.com/isaac-sim/IsaacSim.git IsaacSim-v6.0.0-dev
cd IsaacSim-v6.0.0-dev
git lfs install
git lfs pull

# Build IsaacSim
./build.sh

After those commands, the issues start when trying to build the Docker image:

• Try 1 command and output:

./repo.sh package_container

Script dir: /home/omniverse/workspace/IsaacSim-v6.0.0-dev
No kit apps found in the config. Define one in your repo.toml configuration file. You can use the '--generate' argument to generate default container template files into the destination folder. 

You can also enable the 'gui_cli' option in your repo.toml configuration file to use a Curses-based interface to select a kit app.

It seems I have to generate one like in --help described (but only available when clonning the branch v6.0.0-dev not the main one):

• Try 2 command and output:

./repo.sh package_container --app isaacsim.exp.full.kit --generate /home/omniverse/workspace/IsaacSim-v6.0.0-dev/isaacsim-full

I guess since fat_package step is skipping there is no way to continue the building process.

I would need help here fixing this. I would appreciate an example in case I have missing something crucial but not trivial.

Thanks in advance for any help

Thanks for reporting this. We're checking with the engineering team regarding the package_container behavior in 6.0.0-dev and will get back to you here as soon as we have an update.

Hi @DiegoTorresBZS,

For building a Docker image of Isaac Sim 6.0.0-dev, the supported flow is the Docker build tools under tools/docker/, not repo.sh package_container. The package_container command comes from the shared Kit SDK repo tooling and expects a fat_package (and related config) that the Isaac Sim repo does not define, so that path currently fails here.
Recommended approach: use the steps in the Docker README:
Docker Build Tools – README

I understand. Thank you for the clarification; I was under the impression that the tools available in the Kit application would also be applicable here. Sorry for the inconvenience.
