Standalone — supports landscaping-assistant#187 pipeline optimization.

User Story

As a CI pipeline, I need access to a persistent gem cache so bundle-install runs in ~10s instead of ~90s.

Context

landscaping-assistant PR #188 added PVC-backed gem caching to .woodpecker.yaml. The PVC woodpecker-bundle-cache has been created in the cluster. The Woodpecker agent needs WOODPECKER_BACKEND_K8S_VOLUMES set so pipeline pods can mount it.

Description

Add one env var to the Woodpecker agent in terraform/modules/ci/main.tf:

WOODPECKER_BACKEND_K8S_VOLUMES = "[{\"name\":\"bundle-cache\",\"persistentVolumeClaim\":{\"claimName\":\"woodpecker-bundle-cache\"}}]"

File Targets

terraform/modules/ci/main.tf (1 line added)

Feature Flag

None.

Acceptance Criteria

Agent env var set via Terraform
terraform apply rolls the agent with the new config
landscaping-assistant pipeline can mount /cache/bundle

Test Expectations

After terraform apply, next landscaping-assistant pipeline should populate the gem cache on first run and use it on subsequent runs.

Constraints

PVC already created manually (kubectl apply). Future: manage via Terraform resource.
ReadWriteOnce means only one pipeline pod can mount it at a time (fine for single-agent setup).

Checklist

PVC created in woodpecker namespace
Agent env var added to Terraform
terraform apply run on infra host
