[BUG] docker engine and desktop expose random ports differently #12846
Description
Description
exposing ports with a random mapping should be able to be described using docker compose language portably across docker engine and docker desktop environments. however, different options need to be supplied in order to achieve the goal.
services:
alpine:
image: nginx:alpine-slim
init: true
ports:
- '81'
- '82'
- target: 80
host_ip: 127.0.0.1
protocol: tcp
command:
- sh
- -c
- 'd=/etc/nginx/conf.d; echo "server { listen 81; location / { return 202; } }" > $$d/81.conf && echo "server { listen 82; location / { return 204; } }" > $$d/82.conf && nginx -g "daemon off;"'
alpine2:
image: nginx:alpine-slim
init: true
ports:
- target: 80
host_ip: 127.0.0.1
protocol: tcp
command:
- sh
- -c
- 'd=/etc/nginx/conf.d; echo "server { listen 81; location / { return 202; } }" > $$d/81.conf && echo "server { listen 82; location / { return 204; } }" > $$d/82.conf && nginx -g "daemon off;"'e.g. this works on mac but on linux i also have to add (next to both host_ip fields) a published field and give it a range.
Steps To Reproduce
- copy this
compose.yamlfile onto two computers, one linux (ubuntu 24/Docker version 28.0.4, build b8034c0), one mac (Docker version 27.5.1, build 9f9e405) - cd into the respective directories and
docker compose up -din both - observe linux not works (until adding
published) - observe mac works
