Limit RAM usage of docker on linux

Question

In windows we can specify the RAM limit for WSL thus limiting the RAM usage of docker as a whole .

Can i do something similar in linux ?

Google search only shows way to limit the usage of induvudual containers.

Thanks in advance..

Answer 1

As explained by theDocker Official Guide you can set limits on memory and cpu (this one only for swarms ).

Answer 2

You can limit memory and CPU on docker daemon with help of systemd unit:
