Capistrano Redmine deployment

Usage

• Update the server entries for the relevant stage in config/deploy/staging.rb or config/deploy/production.rb
• Ensure the MYSQL_HOST and MYSQL_PASSWORD environmental variables are set. The Mysql host name should be a FQDN: dbs-xxxxx.gb1.brightbox.com
• Ensure the target application servers have podman installed. The deployment will error if podman is missing.
• Redmine will be exposed on port 3000 as usual.
• If there is more than one application server, then the container storage areas at .local/share/containers/storage/volumes/redmine_data/_data/ will need syncing together.
• Redmine is run under the user-level systemd of the user specified in the stage file (fedora for Fedora, ubuntu for Ubuntu, etc.)
• cap <STAGE> deploy to install and activate the Redmine container
• cap <STAGE> quadlet:remove to deactivate and remove the Redmine container
• Automatic updates are on. Use a more specific tag, or image hash for redmine_container to lock versions.
