Pre-seed jsonnet terraform provider in grafana image - #1301
Error: Failed to install provider
Error while installing alxrem/jsonnet v2.5.0: could not query provider registry for
registry.terraform.io/alxrem/jsonnet: failed to retrieve authentication checksums for
provider: the request failed after 2 attempts
...
Error: Inconsistent dependency lock file
- provider registry.terraform.io/alxrem/jsonnet: required by this configuration but no version is selected
...
ValueError: Dashboard JSON content not found
The container runs terraform init; make; ... at runtime. When the registry lookup fails, init aborts, the lock file keeps no provider version, terraform apply fails, and extract_dashboard.py reports the misleading Dashboard JSON content not found because the ; in the CMD hid the original error.
Change
benchmark_runner/grafana/Dockerfile
Warm alxrem/jsonnet 2.5.0 into /terraform-plugins at image build time.
Runtime uses terraform init -backend=false -plugin-dir=${TF_PLUGIN_DIR}, so registry.terraform.io is no longer needed at run time.
CMD is now sh -ec with && chaining, so an init failure fails the run with its real error.
benchmark_runner/grafana/perf/dashboard.tf
Pin the provider to 2.5.0 (was >= 2.2.0) so the bundled version and the runtime selection always agree.
No lock file is committed: .terraform.lock.hcl stays ignored, so the runtime lock is generated from the provider bundled in the image.
Testing
Verified with terraform 1.5.4: with -plugin-dir and the provider registry made unreachable (HTTPS_PROXY pointing at a closed port), terraform init -backend=false -plugin-dir=... and terraform apply -auto-approve both succeed and the lock file is written from the local package.
Rebuild and push quay.io/ebattat/run_grafonnet with this Dockerfile — the fix only takes effect once the image is updated.
Consider pinning the image tag instead of :latest in the three call sites.

Bug Fixes
Improved reliability of Grafana performance dashboard setup. Initialization now uses a consistent provider version, and subsequent setup and cleanup steps run only when initialization succeeds. This prevents later steps from continuing after a failed initialization.
terraform init runs inside the run_grafonnet container on every CI run and
queries registry.terraform.io for the alxrem/jsonnet provider and its signed
checksums. When that lookup fails the init aborts, leaving no provider version
in the lock file, so the subsequent terraform apply dies with 'Inconsistent
dependency lock file' and extract_dashboard.py reports the misleading
'Dashboard JSON content not found'.
Warm the provider into a plugin directory at image build time and use
terraform init -plugin-dir at runtime so the registry is not needed. Also
switch the CMD to 'sh -e' with && chaining so an init failure surfaces its
real error, and stop ignoring .terraform.lock.hcl so the provider can be
pinned.

Walkthrough
The Grafana Docker image now seeds Jsonnet provider version 2.5.0 for Terraform runtime use. Runtime initialization uses the seeded provider directory and stops subsequent commands if initialization fails.
Changes: Grafana Terraform provider setup
Layer / File(s)
Summary
Pin and seed Jsonnet provider benchmark_runner/grafana/perf/dashboard.tf, benchmark_runner/grafana/Dockerfile
The Terraform configuration requires Jsonnet provider version 2.5.0. The Docker build initializes the provider and copies it into /terraform-plugins.
Use seeded provider at runtime benchmark_runner/grafana/Dockerfile
Runtime initialization uses /terraform-plugins. If initialization fails, make and terraform destroy do not run.
The change pre-seeds the pinned Jsonnet provider so the Grafana job no longer depends on the registry, and it stops on init failure. A reused local workspace with an old ignored lock file may need that lock removed. No merge-blocking risk remains.

Explanation
The title "Pre-seed jsonnet terraform provider in grafana image" matches the main change. The raw summary shows the Grafana Dockerfile now bundles the alxrem/jsonnet provider at build time into /terraform-plugins, and dashboard.tf pins the provider to 2.5.0. The title is specific, short, and free of file lists or vague wording. It does not mention the runtime init and error-handling changes, but the title does not need to cover every detail.

- Line 22: Update the Terraform provider configuration in the image build so the
bundled alxrem/jsonnet version exactly matches the version selected in
.terraform.lock.hcl; establish that selection before committing the lock file,
and keep runtime initialization and the bundled plugin aligned.

Bundling a provider range in the image can select a different version than a
committed lock file, which would break 'terraform init -plugin-dir' at runtime.
Pin the exact version in both the image build and dashboard.tf, and keep
.terraform.lock.hcl ignored so the runtime lock is always generated from the
bundled provider.
