In-Place Upgrade Possible ?

[beadon]

After going through this upgrade path, I thought it might be nice to have an "upgrade" button on the UI to handle the quick upgrade when the user has a git-managed install running.

The commands are straightforward, as you know - they're just not chained together where $tag is the latest available version.

git pull
git checkout $tag
rm package-lock.json
rm -rf node_modules
npm install
npm run build

If the user is using systemd, and maps the install with something like this in /etc/systemd/system/flood.service , or opt to install it for the user --

[Service]
WorkingDirectory=/opt/flood
ExecStart=/usr/bin/env PATH=/home/flood/.nvm/versions/node/v18.3.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin /home/flood/.nvm/versions/node/v18.3.0/bin/npm start
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=notell
User=flood
Group=flood
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target

For this, the process just needs to exit, and will be restarted by the monitoring systemd script, the user can check the about details to see the version has upgraded (or not).

Alternately - but this requires sudoers permissions to manage the process

systemctl restart flood
