Feature

Lineage

Cross-repo from ldraney/landscaping-assistant#62

Repo

ldraney/pal-e-platform (Terraform CI module)

User Story

As a developer I want CI pipelines to run without queuing behind stale builds so that prod deploys are not blocked by already-merged branch pipelines.

Context

Woodpecker agent is configured with replicaCount = 1. Every merge triggers 2-3 pipelines (branch push, PR event, main push) that all compete for a single agent. Two fixes needed: scale agent replicas to 2 and enable auto-cancel for superseded pipelines.

File Targets

terraform/modules/ci/main.tf — bump agent replicaCount from 1 to 2, add WOODPECKER_PIPELINE_CANCEL_PREVIOUS server env var
terraform/modules/ci/variables.tf — add variable for agent replica count

Acceptance Criteria

Agent replicaCount = 2
Auto-cancel enabled for superseded pipelines via WOODPECKER_PIPELINE_CANCEL_PREVIOUS
tofu plan output reviewed before apply

Test Expectations

tofu plan shows replicaCount change from 1 to 2
tofu plan shows new WOODPECKER_PIPELINE_CANCEL_PREVIOUS env var
Push twice to same branch — first pipeline cancels automatically (post-apply)

Constraints

Terraform change requires tofu plan / tofu apply (Lucas approval)
Platform-wide change: replica scaling and auto-cancel affect all repos sharing this Woodpecker instance
Cluster runs on a single k3s node
