I have a problem with a debian container in a cluster model. I'm starting a process in 3 containers that needs to communicate each other but during the process of initial communication an exception associated to the TCP buffer size its generated.
Following this post https://developer.ibm.com/answers/questions/236787/getting-warning-message-dcsv9413w-failed-to-set-bu/ I tried to change the settings net.ipv4.tcp_rmem
and net.ipv4.tcp_wmem
but they does not exist in the container, and reading another posts, it looks docker does not allow to change this kind of setting. Can anyone help?
