Update Databricks CLI to v1.20.0 and remove Terraform bundling by rugpanov · Pull Request #2243 · databricks/databricks-vscode

rugpanov · 2026-10-08T13:32:25Z

Changes

Databricks CLI v1.20.0 removes the Terraform deployment engine and the hidden bundle debug terraform command. Packaging called that command to download Terraform and the Databricks provider. Thus #2241, the plain version bump, fails packaging, and all e2e jobs fail with it. This PR replaces #2241.

Fixes #2166: the VSIX no longer ships the Terraform v1.5.5 binary that security scans flag.

Bump the bundled CLI to v1.20.0.
Stop bundling Terraform. The VSIX now contains only bin/databricks. The setupCLIDependencies.ts packaging step and its host-CLI download are gone.
Stop setting the DATABRICKS_TF_* variables for CLI processes and integrated terminals, and stop writing the Terraform CLI config on activation. The extension clears its terminal variables on each activation, so old values do not stay.
Remove the Terraform-engine deprecation warning, its bundleTerraformEngineWarning telemetry event, and its databricks.bundle.hideTerraformEngineWarning state key. CLI v1.20.0 rejects engine: terraform in validate, so the warning cannot show.

Backward compatibility

A bundle on the Terraform engine fails validate and deploy with the CLI error. The CLI error tells the user to remove bundle.engine, links the migration guide, and migrates existing Terraform state automatically.
A user can pin CLI v1.19.x or lower with databricks.cli.path, or put an older databricks first on PATH in a terminal. That CLI no longer gets the bundled Terraform. It downloads Terraform at runtime, and this fails on restricted networks. We accept this, because the extension moves to the direct engine.

Tests

Unit tests with the bundled CLI v1.20.0: 1290 pass, 0 fail.
yarn run build and yarn run test:lint pass.
./scripts/package-vsix.sh darwin-arm64: the VSIX builds. extension/bin/ contains only databricks, and the packaged package.json has no terraformMetadata.
CI integration tests (full e2e suite on the packaged VSIX, Linux and Windows): all 46 jobs pass. On the first attempt, deploy_and_run_job on Linux timed out while it waited for the job run status. The deploy step had already passed. The re-run of that job passed.

*Why*: * CLI v1.20.0 removes the Terraform deployment engine and the hidden `bundle debug terraform` command. * Packaging called that command to download Terraform and the provider, so the VSIX build failed and every e2e job failed with it. * With the engine gone, the bundled Terraform binary, the `DATABRICKS_TF_*` env vars, and the Terraform-engine warning are dead code. *What:* * Bump `cli.version` to 1.20.0. * Stop bundling Terraform: delete `setupCLIDependencies.ts` and its step (plus the host-CLI download it needed) in `package-vsix.sh`, and the now-unused `BUILD_PLATFORM_ARCH`. * Remove `terraformUtils.ts`, the `DATABRICKS_TF_*` env vars from CLI and terminal environments, and the Terraform CLI config write on activation. The terminal env collection is already cleared on each activation, so old values do not stay. * Remove the Terraform-engine warning (`BundleEngineManager`), its telemetry event, its state key, and the `engine` field it read from validate output. CLI v1.20.0 rejects `engine: terraform`, so the warning can no longer show. * Drop the now-unused `extract-zip` dev dependency and fix Terraform mentions in comments. *Verification:* * `yarn install --immutable`, `yarn run build`, `yarn run test:lint`: pass. * Unit tests against the bundled CLI v1.20.0: 1290 passing, 0 failing. * `./scripts/package-vsix.sh darwin-arm64`: VSIX builds; `extension/bin/` has only `databricks`, and the packaged `package.json` has no `terraformMetadata`.

## packages/databricks-vscode ## (2026-10-12) * Remove the Terraform deployment engine, as part of the update to Databricks CLI v1.20.0 (#2243) ([b087b77](b087b77)). Bundles now always deploy with the direct engine: setting `bundle.engine: terraform` or `DATABRICKS_BUNDLE_ENGINE=terraform` is an error, and if existing Terraform state can't be migrated, the deploy fails instead of falling back to Terraform. If you still need Terraform, stay on extension v2.20.0. The extension also no longer ships the Terraform binary that security scans flagged (#2166). See the [CLI release notes](https://github.com/databricks/cli/releases/tag/v1.20.0) for details * Verify TLS certificates for SDK calls again by default: an unset `databricks.proxy.strictSSL` now falls back to `http.proxyStrictSSL` (verification was skipped since v2.19.0), and honor `http.systemCertificates` (#2244) ([8654191](8654191)) * Sort folders alphabetically in the Workspace File System view (#2233) ([9b26c33](9b26c33)), see #2231 ## packages/databricks-vscode-types ## (2026-10-12) No user-facing changes. ## Curation notes * Minor bump (not patch): the bundled CLI moves to v1.20.0, which removes the Terraform deployment engine. Bundles that still deploy with Terraform break. The 3 `[under feature flag]` `feat` commits below would also need a minor bump. * The VSIX sizes drop a lot against v2.20.0, because the CLI v1.20.0 bump removes Terraform from the VSIX (#2166). This is expected. * Left out of the changelog: * [under feature flag] #2230: Unity Gateway sign-in. It is gated on the `chat.unityGateway` experiment. * [under feature flag] #2238: Unity Gateway model discovery. Chat does not use it yet. * [under feature flag] #2237: Unity Gateway connection row in the Configuration view. * #2240: dependency-only bump of `shell-quote`. * Stripped the generated issue refs and the `closes` keywords, so merging does not auto-close issues.
