I am pretty new to docker and was following the documentation found here, trying deploy several containers inside dind using docker-compose 1.14.0 I get the following 

docker run -v /home/dudarev/compose/:/compose/ --privileged docker:dind /compose/docker-compose
/usr/local/bin/dockerd-entrypoint.sh: exec: line 21: /compose/docker-compose: not found

Did I miss something?

docker-compose docker

There is official docker image on dockerhub for docker-compose, just use that.

Follow these steps:

  • Create a directory on host mkdir /root/test
  • Create docker-compose.yaml file with following contents:
version: '2'

services:
  web:
    build: .
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  redis:
    image: redis
  • Run docker run command to run docker-compose inside the container.
docker run -itd -v /var/run/docker.sock:/var/run/docker.sock -v /root/test/:/var/tmp/ docker/compose:1.24.1  -f /var/tmp/docker-compose.yaml up -d

NOTE: Here /var/tmp directory inside the container will contain docker-compose.yaml file so I have used -f option to specify complete path of the yaml file. Also docker.sock is mounted from host onto the container.

Hope this helps.
