# Docker Compose for Local Development
# Next.js + Neon Stack
#
# One compose project per worktree. The harness sets
# COMPOSE_PROJECT_NAME=morph-{feature}, which prefixes every container, network
# and volume — so two features running side by side never share a resource.
# Explicit `container_name:` entries are NOT prefixed, which is why this file
# declares none: a named container is a collision waiting for the second
# worktree.
#
# Host ports come from the feature's port block (see env-allocator.js):
#   PORT          block + 0   (web)
#   API_PORT      block + 1   (api)
#   POSTGRES_PORT block + 2   (postgres)
#   REDIS_PORT    block + 3   (redis)
# Every published port reads one of those variables with a single-stack
# default. A fixed host port here would defeat the block no matter what the
# harness injects — `morph-spec e2e up` and the verify e2e node refuse such a
# compose inside a worktree (`compose-not-isolable`).
#
# Named volumes are reclaimed by `morph-spec finish` when the feature closes
# (`--keep-volumes` opts out). Healthchecks are what make `up --wait`
# meaningful: without them Compose reports "started" the moment the process
# launches, and the e2e node would navigate an application not serving yet.
#
# The harness also exports PLAYWRIGHT_BASE_URL for the allocated port, so
# `playwright.config.ts` must read it instead of hardcoding a URL:
#   baseURL: process.env.PLAYWRIGHT_BASE_URL ?? `http://localhost:${process.env.PORT ?? 3000}`
