Issue

Because of not supporting to specify the following docker run parameter, containers in ECS cannot resize the shared memory.

--shm-size

Solution

Here is a workaround:

1. In order to operate devices with a container, execute docker run command with "--priviledge=true"

2. Run the following scripts with a contianer,

shm_dir=/dev/shm

umount $shm_dir

mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=<size, e.g. 500M, 1G> shm $shm_dir
