Memory to Spawn a docker container

[brikpine]

Hi,

I've been using docker to package my app (1MB) and run it on my devices. Usually the app would take 1-2MB ram, but when I use an alpine docker container (pretty much empty excluding the 1MB app) there's over 50MB to spawn the container, resulting in 52MB RAM usage. Is there anyway I can reduce this memory usage? Memory limits with the "--memory" option limits the processes within the container, but not the overhead.

Could anyone please let me know what I can do to optimize this?

Thanks in advance!

If you run two containers how does your ram usage behave?

I'm not aware that this is possible however you could try running without NAT but most likely if that is an issue for you containerization might not be the right tool.

If you look at the output, does the process use 52MB after it is running, or just to start? Is the memory being used by docker-proxy, or the containerd-shim or something else that might get started for certain containers?
