It does the same as haproxy but haproxy is better

I prefer to be there when container ar updated so that I can promptly fix anything that breaks.

I have 2 watchtower instances in a docker-compose, the first container ‘watchtower-monitor’ uses command: --monitor-only and warns me over gotify about the availability of updates but does not modify anything, the second ‘watchtower-once’ uses command: --run-once and it is usually inactive since it performs all updates once and than exits. When i am ready to update everything I just docker-compose start watchtower-once container to start the updates.

4gb ram is a bit low, mb that supports 16gb or 32gb of cheap RAM are ideal because it is possible to max the ram with little money. How much ram does it support?
