|
+# Pulls the latest code from master, redeploys the app, and restarts the
|
|
|
+# service. Runs INSIDE the Alpine LXC container as root. Does not touch the
|
|
|
+# Proxmox host.
|
|
|
+#
|
|
|
+# Usage (inside the container):
|
|
|
+# sh /opt/yaar/update.sh # update code + restart service
|
|
|
+# sh /opt/yaar/update.sh --deps # also upgrade yt-dlp / Flask / Gunicorn
|
|
|
+# sh /opt/yaar/update.sh --reboot # reboot the whole container after update
|
|
|
+# yaar-update # convenience alias (installed by setup.sh)
|
|
|
+#
|
|
|
+# One-liner (always fetches the newest update logic too):
|
|
|
+# curl -fsSL https://gogs.av2x.dev/av2x/yaar/raw/master/update.sh | sh
|
|
|
+#
|
|
|
+# Safety: the current app.py and index.html are backed up before overwriting.
|
|
|
+# If the service fails to start on the new code, the previous version is
|
|
|
+# automatically restored and the service restarted, so YAAR is never left down.
