I was wondering whether there is a way to automatically limit the number of CPUs all docker container can use when running as by default, each container uses all the available resources.

When running the docker run command, I know I can specify the number of CPUs (--cpus=) but in my current case, the containers are started using another application (ShinyProxy) which does not allow me to specify this option.

I already spent a lot of time on this issue (e.g. using cgroups) but I haven't been able to set up anything working.

E.g, I tried to implement the solution proposed hereafter but I was not able to achieve any result. https://stackoverflow.com/a/46557336/8939750

Many thanks for your help,

  • have a look at the options and set whats needed https://docs.docker.com/engine/reference/commandline/run/#options – Pork Chop Feb 27 '19 at 09:52
  • Thank you for your fast answer... unfortunately, this won't be working for me as I cannot use docker run (see the original post) because those are run using another software (shinyproxy). – Sylvain Brohee Feb 27 '19 at 09:56
