How to run Docker and Docker-Compose from a Dockerized Jenkins container?

Question

I have this docker-compose to run a Dockerized Jenkins container,

version: '2'
services:
  jenkins:
    image: 'jenkinsci/blueocean'
    environment:
      - JENKINS_OPTS="--prefix=/jenkins"
    user: 'root'
    ports:
      #host:container
      - '8888:8080'
    volumes:
      #host:container
      - /dati/jenkins:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin:/usr/bin
      - /usr/local/bin:/usr/local/bin

I'm able to run

docker ps

but not

docker-compose -v

which gives me docker-compose: not found .

However I'm able to list it from inside the container:

[root@dev-machine ~]# docker ps
CONTAINER ID        IMAGE                                  COMMAND                   CREATED             STATUS                  PORTS                               NAMES
d183202f2b2a        jenkinsci/blueocean                    "/sbin/tini -- /usr/…"    15 hours ago        Up 15 hours             50000/tcp, 0.0.0.0:8888->8080/tcp   jenkins-compose_jenkins_1

[root@dev-machine ~]# whereis docker-compose
docker-compose: /usr/bin/docker-compose
[root@dev-machine ~]# docker exec -it d183202f2b2a sh
/ # ls -l /usr/bin/docker-compose
-rwxr-xr-x 1 root root 218 Oct 26 09:09 /usr/bin/docker-compose
/ #

I'm sure the user of Jenkins is root, as shown below from inside the container:

/ # whoami
root

What am I missing to make Docker-Compose work from inside a Dockerized Jenkins container?

Answer 1

Jenkins Container in docker-compose file: enter image description here

You should add this rows in docker-compose file.

Don't forget /usr/local/bin/docker-compose file is mustn't empty in your server machine.

Jenkins execute result: enter image description here
