  • Restores the Yarn Berry v4 migration that was previously reverted
  • Updates project to use Yarn 3.6.4 instead of Yarn Classic v1.22.22
  • Addresses Red Hat policy requirements for phasing out Yarn Classic
  • Enables hermetic builds with Konflux Hermetic support

Changes Made:

  • Restored .yarn/releases/yarn-3.6.4.cjs - Yarn Berry executable
  • Restored .yarnrc.yml - Yarn Berry configuration with hermetic settings
  • Updated .gitignore - Added Yarn Berry patterns (.pnp.*, .yarn/cache, etc.)
  • Updated Dockerfile - Modified build process for Yarn Berry (Node.js 18)
  • Regenerated yarn.lock - Converted from Classic to Berry format
  • Fixed webpack configuration conflicts

Testing:

  • yarn install - Dependencies install successfully
  • yarn build - Build completes successfully with same warnings as v1
  • All existing functionality preserved

Context:
This un-reverts the changes from PR #1543, which previously reverted the Yarn Berry migration from PR #1538. This migration was completed before but reverted due to temporary issues that may now be resolved.

Policy Compliance:
Addresses Red Hat policy requirements:

  • PSS.SBR.02.03 - Hermetic builds
  • PSS.SBR.02.04 - Central Artifact Registry support
  • End of Q1 2026 deadline for Yarn Classic migration
