Increasing the size of /dev/shm for the Docker driver
#20837

I found a workaround. It's good enough for me. $ minikube ssh
docker@minikube:~$ sudo mount -o remount,size=32G /dev/shm
docker@minikube:~$ df -h

What Happened?
I'm trying to run a fairly complicated system inside Minikube (driver and container runtime Docker with NVIDIA GPUs). The pods use
/dev/shmheavily for IPC -- we need gigabytes -- and our pods havehostIPC: true. However, I see that the default size of/dev/shminside the Minikube Docker container is64Mand I can't find a way to increase its size. Ideally, I'd like to either be able to pass--ipc hostor--shm-size 50gto thedocker runcommand that spins up the Minikube Docker container.Attach the log file
