Exit Code 255 on all Docker exec commands

Build Environment
1

We’re trying to get a Docker based build environment up and running, but I’m having trouble running anything via docker exec, as I’m just getting exit code 255 on all commands, and an error message that I don’t really understand:

open /proc/self/oom_score_adj: no such file or directory

We’re running Docker 1.10.0 and Docker Compose 1.6.2. My circle.yml file is pretty simple:

machine:
  pre:
    - curl -sSL https://s3.amazonaws.com/circle-downloads/install-circleci-docker.sh | bash -s -- 1.10.0
  services:
    - docker

dependencies:
  override:
    - sudo pip install docker-compose
    - sudo service mysql stop
    - docker-compose -p rwb -f docker/docker-compose.yml up -d
    - docker exec rwb_db_1 apt-cache policy mysql-server

And the docker-compose.yml file is pretty simple too:

version: '2'

services:
  db:
    image: mysql:5.7.10
    ports:
      - 3306:3306
    volumes:
      - ..:/data
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: my_database
      MYSQL_USER: admin
      MYSQL_PASSWORD: password

I know that the support for these versions of Docker and Docker Compose is not yet official, but I’m hoping that someone can help me get it working. Does anyone have any insights as to why I’m getting this error?

Thanks!

Well, it looks like this is related to LXC issues as mentioned here: Docker 1.10.0 is available (Beta)
