Split the raggr service into raggr-blue (8080) and raggr-green (8081) behind compose profiles, add a /api/health endpoint and container healthcheck, and add scripts/deploy.sh to build the inactive color, wait for it to become healthy, then gracefully stop the old one. Makefile targets resolve the active color automatically. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# Zero-downtime blue-green deploy.
|
|
#
|
|
# Builds the inactive color, starts it, waits for its healthcheck to pass,
|
|
# then gracefully stops the old color. Caddy health-checks both ports
|
|
# (8080 = blue, 8081 = green) and routes traffic to whichever is healthy,
|
|
# so the swap is invisible to clients.
|
|
#
|
|
# Caveats:
|
|
# - Migrations run on the new container's startup while the old one still
|
|
# serves, so they must be backward-compatible (additive changes only;
|
|
# destructive changes need a two-step deploy).
|
|
# - During the brief overlap both containers run pull-only Obsidian sync
|
|
# against the shared ./obvault mount.
