Are we sure that this will work in disconnected envs?

Hello @atheo89 I thought that it would work because this would be done during the image build time. The idea is now that Notebook images don't need a custom bootstrapper.py we could download it from Elyra and use the new system property we introduced: ELYRA_INSTALL_PACKAGES to prevent Elyra from trying to download packages - this new flag should do that

Can we curl that file from a fixed tag (associated with the Elyra version in the image) instead of main?
EDIT: nvm, I saw the other comment below.

isn't this bootstrapper installed together with the odh-elyra package? Can't we grab it from python's site-packages? And if it is not installed, can't we install it that way?

that's a great suggestion, it should be with the elyra package, it would be better to copy it from there - I will check and update the Dockerfile accordingly

@jiridanek I found the local bootstrapper.py and copy it to utils on script setup-elyra.sh - would it be the best place to do it?

Thanks!

Sounds legit to me, yes

@coderabbitai it seems that things are difficult since odh-elyra is not being installed in runtime images; we should install elyra in runtime images, or possibly split off the bottstrapper.py into its own subpackage and install that in runtime images

The only required change will be delete the local boostrapper to use the one from Elyra - I am doing this with curl because Elyra package is not installed in runtime images;
Please only merge this after Elyra 4.3.2 release - which we should make ELYRA_INSTALL_PACKAGES=true only on our fork, so we will not have to setup this in runtime images

and

The only problem is that I don't have this information in runtime images because Elyra is not installed there, only the runtime image dependencies are installed.

(these are comments in sibling threads, from @jesuino, on this PR)

@coderabbitai create github issue to install odh-elyra on runtime images, because ^^^

@jiridanek You're raising a valid architectural concern. Downloading a Python file via curl at build time is less maintainable than proper package-based installation. Let me discuss the tradeoffs:

Current approach (curl download):

• ✅ Keeps runtime images lightweight (no Elyra dependencies)
• ✅ Works in air-gapped environments (file cached in image)
• ❌ Version management is manual (hardcoded URL with version tag)
• ❌ No dependency resolution via package managers
• ❌ Less conventional Python packaging practice

Alternative 1: Install full odh-elyra in runtime images:

• ✅ Standard package management
• ✅ Proper dependency resolution
• ❌ Adds Elyra and all its dependencies to runtime images (potentially significant bloat)
• ❌ May conflict with the design goal of keeping runtime images minimal

Alternative 2: Split bootstrapper.py into separate lightweight package:

• ✅ Standard package management without full Elyra overhead
• ✅ Minimal footprint in runtime images
• ✅ Easier version management
• ❌ Requires creating and maintaining a new package
• ❌ Adds complexity to Elyra project structure

Questions for consideration:

1. What's the rationale for keeping Elyra out of runtime images? Is it purely size/dependency concerns, or are there other architectural reasons?
2. What are the actual dependencies of bootstrapper.py? Could they be satisfied without pulling in the full Elyra package?
3. Would the Elyra upstream project be open to splitting off bootstrapper.py as a separate minimal package (e.g., elyra-kfp-runtime)?

Given that this PR is already sizable and time-sensitive (code freeze mentioned), one approach could be:

• Accept the current curl-based solution as a short-term fix
• File an issue to explore creating an elyra-kfp-bootstrapper or similar minimal package for the longer term
• This would give time to discuss with upstream Elyra and evaluate the best architectural approach

What do you think? Should we proceed with the current approach and plan for a more robust solution in a follow-up, or block this PR until we resolve the architecture question?

  --body "## Context

Currently, the odh-elyra package is not installed in runtime images, which requires downloading the \`bootstrapper.py\` file directly from the upstream GitHub repository using \`curl\` (as seen in PR #2555).

## Proposal

Consider one of the following approaches:
1. Install the odh-elyra package on runtime images so that \`bootstrapper.py\` is available locally
2. Split off \`bootstrapper.py\` into its own subpackage that can be installed independently on runtime images

Installing odh-elyra (or a subset of it) would eliminate the need for downloading files from external URLs during image builds and provide better integration with the Elyra ecosystem.

@jiridanek I've created GitHub issue #2681 to track installing odh-elyra on runtime images. The issue proposes either installing the full odh-elyra package or splitting off bootstrapper.py into a separate subpackage, which would eliminate the need for the current curl-based download approach. The issue has been assigned to @jesuino.

⚠️ Potential issue | 🟠 Major

Align bootstrapper version with Elyra bump and avoid network-dependent builds.

We now pull bootstrapper.py at build time from Elyra tag v4.3.0, but the rest of this PR upgrades ODH Elyra to 4.3.1. Shipping a 4.3.0 bootstrapper alongside 4.3.1 bits is a mismatch that can regress the fixes we’re picking up. In addition, downloading from GitHub during the build defeats disconnected/air-gapped builds—the very scenario the new ELYRA_INSTALL_PACKAGES=false knob is supposed to support. Please vendor the correct 4.3.1 bootstrapper (or fetch it from a pre-staged artifact inside the image) so the Docker build stays reproducible and works without external network access.

In runtimes/minimal/ubi9-python-3.12/Dockerfile.cpu around lines 77-78, the
Dockerfile downloads bootstrapper.py from Elyra tag v4.3.0 at build time which
mismatches the repo bump to v4.3.1 and prevents air-gapped/disconnected builds;
replace the curl step with a reproducible, network-free approach by vendoring
the v4.3.1 bootstrapper into the build context (or copying it from a pre-staged
artifact inside the image/build context), update the Dockerfile to ADD/COPY that
local file into ./utils/bootstrapper.py instead of curling, and ensure the
vendored file version matches Elyra v4.3.1 (optionally add a checksum or comment
noting the source and tag).

what if we do

cp /opt/app-root/lib/python3.12/site-packages/elyra/kfp/bootstrapper.py ...

@jiridanek, that's an excellent solution! 🎯

Copying bootstrapper.py from the installed Elyra package would indeed solve both issues:

• ✅ Version alignment: Automatically uses the correct 4.3.1 version
• ✅ Air-gapped builds: No network dependency during build

However, there's an ordering consideration in the Dockerfile. Currently:

1. Line 75: COPY ${MINIMAL_SOURCE_CODE}/utils ./utils/
2. Line 77-78: curl bootstrapper.py (problematic)
3. Line 80: uv pip install (this installs odh-elyra and creates site-packages)

To implement your approach, the copy would need to happen after the uv pip install step, since that's when the Elyra package gets installed to site-packages. Something like:

# Copy Elyra dependencies for air-gapped environment
COPY ${MINIMAL_SOURCE_CODE}/utils ./utils/

RUN echo "Installing softwares and packages" && \
    uv pip install --strict --no-deps --no-cache ... && \
    # Copy bootstrapper from installed Elyra package
    cp /opt/app-root/lib/python3.12/site-packages/elyra/kfp/bootstrapper.py ./utils/bootstrapper.py && \
    chmod -R g+w /opt/app-root/lib/python3.12/site-packages && \
    fix-permissions /opt/app-root -P

This approach is cleaner, more maintainable, and naturally stays in sync with the Elyra version specified in pylock.toml. 👍

#!/bin/bash

@jiridanek, perfect! ✅ The changes look great:

1. Version alignment issue resolved: The problematic curl downloading v4.3.0 has been removed from the Dockerfile.

2. Air-gapped build support maintained: The setup-elyra.sh script now implements exactly what you suggested:

   cp /opt/app-root/lib/python3.12/site-packages/elyra/kfp/bootstrapper.py /opt/app-root/bin/utils/

3. Clean architecture: The minimal runtime serves as a base without Elyra-specific setup, and derived images (like datascience) handle the bootstrapper copy in their setup scripts after package installation.

This approach ensures the bootstrapper version always matches the installed odh-elyra package (4.3.1) and works perfectly in disconnected environments. The solution is maintainable and self-documenting with the comment acknowledging ELYRA_INSTALL_PACKAGES=false requirement. Nice work! 🎯

elyra package is not on runtime image, so copying bootstrapper.py from python packages would not be possible as the package is not there.

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

@coderabbitai how was the previous comment resolved?

@jiridanek, great question! Here's what happened:

The resolution: The curl version tag was updated from v4.3.0 to v4.3.1 across all runtime Dockerfiles.

Looking at the current state, all runtime images now download the correct version:

RUN curl -fL https://raw.githubusercontent.com/opendatahub-io/elyra/refs/tags/v4.3.1/elyra/kfp/bootstrapper.py \
         -o ./utils/bootstrapper.py

Why the cp approach doesn't apply here:

harshad16 correctly identified that my earlier suggestion (copying from /opt/app-root/lib/python3.12/site-packages/elyra/kfp/bootstrapper.py) only works for workbench/Jupyter images where the odh-elyra package is installed.

The repository has two distinct image types:

1. Runtime images (runtimes/*): Elyra is NOT installed → must use curl or vendor the file
2. Workbench images (jupyter/*): Elyra IS installed → can copy from site-packages

For these runtime images, the curl approach is necessary since there's no installed Elyra package to copy from. The version alignment issue has been fixed (v4.3.1 throughout), though this does mean runtime image builds still require network access during the Docker build phase. That's an acceptable trade-off given the architectural constraint.
