Conversation
Documents how to keep downloaded modules and providers between jobs of the same workspace: the helm chart executor.cache block, the executor's TerraformDataDirCacheRoot setting, and the plain TF_DATA_DIR workspace environment variable that works with any version. Cross-links the provider cache page. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
New page Workspaces → Module Cache explaining why every job re-downloads modules and providers (throw-away clone) and the three ways to keep them between jobs of the same workspace:
executor.cacheblock (feat(executor): executor.cache block for provider + module caching (chart 4.8.0) terrakube-helm-chart#293),TerraformDataDirCacheRootsetting (feat(executor): per-workspace terraform data directory cache (TF_DATA_DIR) terrakube#3478),TF_DATA_DIRworkspace environment variable, which works with any version.Includes the caveats (pinned versions since
initruns without-upgrade, lock file vs.TF_PLUGIN_CACHE_MAY_BREAK_DEPENDENCY_LOCK_FILE, RWX volumes for several replicas, how to reset a workspace's cache) and a cross-link from the existing Provider Cache page.🤖 Generated with Claude Code
