# Deploy the Hub to a host: rsync the repo, install deps, build, restart service.
|
|
#
|
|
# Configure these env vars (e.g. in CI secrets):
|
|
# PLATFORM_DEPLOY_HOST required
|
|
# PLATFORM_DEPLOY_SSH_KEY required (private key for the deploy user)
|
|
# PLATFORM_DEPLOY_USER optional, defaults to deploy
|
|
# PLATFORM_DEPLOY_PORT optional SSH port, defaults to 22
|
|
# PLATFORM_DEPLOY_HUB_PORT required Silo listener port
|
|
# PLATFORM_DEPLOY_BASE optional, defaults to /srv/curriculum-project-hub
|
|
# PLATFORM_DEPLOY_RELEASE optional immutable release id, defaults to git HEAD
|
|
# PLATFORM_DEPLOY_INSTANCE required, Silo instance id
|
|
# PLATFORM_DEPLOY_MEMORY_MAX / CPU_QUOTA / TASKS_MAX required ceilings
|
|
# PLATFORM_DEPLOY_HEALTH_URL optional, defaults to http://127.0.0.1:8788/api/healthz
|
|
# The target host must have Node.js 24+, npm, rsync, PostgreSQL client tools
|
|
# (`pg_isready`), systemd, bubblewrap (`bwrap`) and `socat` (for the ADR-0018 agent sandbox),
|
|
# and a compatible `cph` binary named by platform.env. The service installer
|
|
# provisions the dedicated non-root identity and persistent directories.
|
|
# Use a dedicated `deploy` user that has passwordless sudo for systemctl and
|
|
# writing the named /etc/systemd/system/cph-hub-<instance>.service through the installer.
