如何增加 docker 容器中/dev/shm 的大小 [英] How to increase the size of the /dev/shm in docker container

问题描述

Currently When I create new docker container the size of the shared memory directory is limited to 64MB. But, I need to increase this size since my application depend on this shared memory. Is there any way to increase the size of /dev/shm in docker container? I heard that the 64MB is hard coded in the docker code, How to install docker from source and change the value of the /dev/shm?

解决方案

If you're using docker-compose, you can set the your_service.shm_size value if you want your container to use that /dev/shm size when running or your_service.build.shm_size when building.

Example:

version: '3.5'
services:
  your_service:
    build:
      context: .
      shm_size: '2gb' <-- this will set the size when BUILDING
    shm_size: '2gb' <-- when RUNNING
