Building on top of the answer by Joepreludian, focusing on docker-compose: You can use the user: and volumes: options in the compose file. For example: my-service: image: ubuntu:latest user: ${MY_UID}:${MY_GID} volumes: – /etc/passwd:/etc/passwd:ro – /etc/group:/etc/group:ro and define these variables where you are starting your compose: MY_UID=”$(id -u)” MY_GID=”$(id -g)” docker-compose up

Use -f option to specify the file name. Example: docker-compose -f docker-compose.test.yml up
The env_file optin will only set environment variables in the docker container itself. Not on the host which is used during the compose ‘build’. To define your port as env var you should use the .env file as described here In your case create a .env file which contains:: PORT=5000 and the docker-compose.yml: version: ‘3’ … Read more
There is an apposite parameter to use: web: image: an_image-image:1.0 container_name: my-container privileged: true entrypoint: [“/usr/sbin/init”] ports: – “8280:8280”
