GOMAXPROCS should be set to the number of CPU cores that the container is allowed to use, if you’re allocating fractional CPU round down, unless you’re allocating less than 1 CPU core in which case round up. GOMAXPROCS=max(1, floor(CPUs)) can be used to calculate the value. If you find it easier Uber has open sourced a library automaxprocs to calculate this value for you from your container’s cgroups automatically.
