Hi Dominik, I had same opinion as yours but turns out it won’t work. The configuration defined in sysctls won’t work because the net.core.wmem parameters cannot be exposed or modified within a Docker container. These settings are managed at the host level and aren’t adjustable from within the container environment. So these lines won’t work in docker compose/side car image:
sysctls:
- net.ipv6.ip6frag_time=3
- net.ipv6.ip6frag_high_thresh=134217728
- net.core.wmem_max=12582912
- net.core.rmem_max=12582912
- net.core.wmem_default=16384000
- net.core.rmem_default=16384000
Therefore I am stucked in here. I agree with you this is the right direction, just no idea about how to implement these. Really wish we can found a solution about it.
