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?
There is official docker image on dockerhub for docker-compose, just use that.
Follow these steps:
mkdir /root/testdocker-compose.yaml file with following contents:version: '2'
services:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
redis:
image: redis
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.
Add docker-compose installation to your Dockerfile before executing docker run.
For example, if you have an Ubuntu docker, add to your Dockerfile:
RUN aptitude -y install docker-compose
RUN ln -s /usr/local/bin/docker-compose /compose/docker-compose
Because it looks like if your entry-point looks up docker compose in /compose folder, while docker-compose is installed in /usr/local/bin by default.
If you want a concrete docker-compose version (for example 1.20.0-rc2):
RUN curl -L https://github.com/docker/compose/releases/download/1.20.0-rc2/docker-compose-`uname -s`-`uname -m` -o /compose/docker-compose
RUN chmod +x /compose/docker-compose
RUN curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose RUN chmod +x /usr/local/bin/docker-composehere is a full dockerfile to run docker-compose inside docker
FROM ubuntu:21.04
RUN apt-get update
RUN apt-get upgrade -y
RUN apt-get install -y python3
RUN apt-get install -y pip
RUN apt-get install -y curl
RUN curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
RUN chmod +x /usr/local/bin/docker-compose
dindis a must, it is used to build and test images and keep the host docker clean, nevertheless the one which is hosted on docker hub is based on busybox and for some reason it seems not to be able to find the binary, but if you build the image from original repo, as it has a proper bash (not ash like in busybox) it find it. I must be something to do with how busybox mounts the filesystem and I am quite confused here.
