Still using docker so you can upgrade most of it on every deployment. As far as the host, modern Linux distros handle security updates automatically and unattended. I do recommend having a backup replica server in standby. If you need to upgrade the kernel on the host you just change the DNS to point to your backup, wait for some time for connections to finish on your primary then restart the primary, ensure it is stable, change DNS back. It’s standard A/B deployment. Nothing special about it. |
