在docker-compose中添加docker run的参数

Question

I am running this command to start a selenium image and run my container:

sudo docker run -d -p 4445:4444 --shm-size 2g selenium/standalone-firefox:latest

I would like to integrate this command to my docker-compose file so I did the following which works:

  selenium:
    image: selenium/standalone-firefox:latest
    container_name: selenium
    restart: on-failure
    ports:
     - 4445:4444

But I need to pass on as well the following parameter: --shm-size 2g
How can I do that in my docker-compose.yml file ?
Thanks!

Answer 1

Use this docker-compose.yml :

version: '3'
services:
  selenium:
    image: selenium/standalone-firefox:latest
    container_name: selenium
    restart: on-failure
    ports:
     - 4445:4444
    shm_size: '2gb'

Run the compose:

docker-compose up

Check it:

docker inspect <container-id> | grep ShmSize
            "ShmSize": 2147483648
