Upgrading a Mattermost Server
is not complicated, but requires some steps that can be mostly automated. I’m watching ‘Releases only’ on the GitHub repository
to get a notification when a new version is available and start the script manually.
Below script assumes, that Mattermost is installed at the default location /opt/mattermost. The script first greps the current download link from the official Mattermost Download page
, displays the found link and asks if it should continue. Rest should be self-explanatory (see echo messages).
October 15, 2021: Updated the script to work with the new Mattermost download page
