Summary

Adds a Collector-specific image profile on top of the StackRox CI image PR.

  • Uses the latest quay.io/stackrox-io/collector-builder:master manifest, pinned to digest sha256:52a3cca5253abb0cd5c3606769d5fd5b8be4cdb4671396f38a792695f07d7696.
  • Retains the OpenShell sandbox contract and StackRox agent/tooling setup.
  • Publishes sandbox-collector-builder for linux/amd64 while third-party binary downloads remain amd64-only.
  • Documents the three selectable StackRox profiles.

Dependent on the NVIDIA/default and Apollo/rox-ci-image PRs.

Summary by CodeRabbit

  • New Features

    • Added a StackRox Collector Builder sandbox image for Linux amd64.
    • Included build tools, Go and Python environments, coding agents, GitHub REST integration, and read-only Atlassian and gopls MCP servers.
    • Added restricted sandbox execution, filesystem controls, controlled Go module networking, trusted paths, and non-privileged operation.
    • Added shell initialization and preconfigured agent settings for a ready-to-use development environment.
  • Documentation

    • Added setup, tooling, environment, integration, credential-handling, and OpenShell synchronization documentation.
    • Documented REST-based GitHub workflows and available sandbox capabilities.

Walkthrough

The pull request adds an amd64 StackRox collector-builder sandbox image. It installs development tools and coding integrations, applies OpenShell policies and settings, adds vendored GitHub skill assets, and registers the image in the build workflow.

Changes

Collector Builder Sandbox

Layer / File(s) Summary
Image build and runtime assembly
.github/workflows/images.yml, profiles/stackrox/README.md, profiles/stackrox/image/sandbox-collector-builder/Dockerfile
The workflow builds the image for linux/amd64. The Dockerfile installs pinned and checksum-verified tools, configures Python and Go environments, copies sandbox assets, and starts Bash as the unprivileged sandbox user.
Sandbox policy and runtime configuration
profiles/stackrox/image/sandbox-collector-builder/{policy.yaml,settings.json,claude.json}, profiles/stackrox/image/sandbox-collector-builder/openshell/{.bashrc,.profile}, profiles/stackrox/image/sandbox-collector-builder/CLAUDE.md
The image gains filesystem, process, and network controls, shell environment initialization, Claude settings, and sandbox usage documentation.
MCP integrations
profiles/stackrox/image/sandbox-collector-builder/{mcp.json,opencode.json}
Claude and OpenCode define read-only Atlassian and gopls MCP integrations.
Vendored OpenShell assets
profiles/stackrox/image/sandbox-collector-builder/openshell/{README.md,skills/github/SKILL.md}
The image includes metadata for the pinned OpenShell assets and a GitHub skill that uses REST-only gh api workflows.

Merge Risk: 🟡 Moderate · up to 43a94

A future build can consume changed uv content despite using the same version tag, weakening the image supply-chain boundary. Pin the source image digest before merging.

The go install command populates a build cache (typically in /root/.cache/go-build when run as root). This cache is not being cleaned in this step. Consider adding go clean -cache -modcache after installing gopls to reduce the final image size.

The base collector-builder image and surrounding documentation state that a Go toolchain is already included. This redundant go installation adds to the image size and may introduce version conflicts. Consider removing this installation and using the go provided by the base image.

This comment states that the base collector-builder image does not contain Go. This contradicts line 32 of this same Dockerfile and the associated README, both of which state that Go is already supplied by the base image. Re-installing the Go toolchain is unnecessary and could lead to version conflicts.

The uv version 0.10.8 is significantly outdated. As a fast-developing tool, using a more recent version is recommended to benefit from performance improvements, security updates, and bug fixes. Please consider updating to a newer release.

Skipped: this profile pins uv 0.10.8 for reproducible image builds and uses the same tested version as the StackRox CI profile. Updating it is a separate dependency-refresh change, not a correctness issue for this PR.

The Dockerfile for this image (line 136) states that the collector-builder base image does not include Go, and then proceeds to install it. This documentation contradicts the Dockerfile by stating that Go is available from the base image. Please clarify whether the base image includes Go and update the documentation to be consistent.

The go install command for gopls does not pin the version, which can lead to non-reproducible builds. It is recommended to use a specific version tag to ensure build consistency.
