Comment on Adding services to an existing Docker nginx container
bjorney@lemmy.ca 1 year agoTo elaborate a bit more, there is the MySQL resource usage and the docker overhead. If you run two containers that are the same, the docker overhead will only ding you once, but the actual MySQL process will consume its own CPU and memory inside each container.
So by running two containers you are going to be using an extra couple hundred MB of RAM (whatever MySQL’s minimum memory footprint is)
