DOCKER-COMPOSE-PORT(1)

📦 version 2.26.1, in debian trixie

💖 docker-compose-port 💖

okay bestie, welcome to the docker-compose-port page, aka the little glow-up that tells you which public port your container is actually wearing ✨ it lives inside the docker-compose manual family, so if you ever get lost just yell for its parent 🫶

✨ NAME ✨

docker-compose-port — print the public port for a port binding 💅

no cap, that's literally the whole job. it looks at a port binding and tells you the public side of it. iconic behaviour honestly.

🌸 SYNOPSIS 🌸

docker compose port [OPTIONS] SERVICE PRIVATE_PORT

so you give it a SERVICE, you give it a PRIVATE_PORT, and it hands you back the public port. the way that it just works 😭💖

🦋 DESCRIPTION 🦋

Prints the public port for a port binding 🎀

that's it. that's the vibe. you ask, it answers, everyone moves on with their day. main character energy fr fr.

💅 OPTIONS 💅

  • -h, --help[=false] — help for port 🙋‍♀️ when you need the manual to explain the manual. set it to false (the default) and it just chills.
  • --index=0 — Index of the container if service has multiple replicas 👯‍♀️ because sometimes your service is not one (1) singular container, it's a whole friend group, and you gotta say which one. default is 0.
  • --protocol="tcp" — tcp or udp 🌐 pick your transport, bestie. default is "tcp".

👑 OPTIONS INHERITED FROM PARENT COMMANDS 👑

  • --dry-run[=false] — Execute command in dry run mode 🧚 pretend you did the thing without actually doing the thing. rehearsal era. default is false.

🌈 SEE ALSO 🌈

⚠️ real talk: these are inherited options, so they're coming from the parent command, not from port itself. don't be confused, be informed 💖

okay and that's the whole page!! this gorgeous little number is from the Mar 2025 release of the DOCKER-COMPOSE-PORT(1) manual — go forth, find your public ports, and slay 💅✨🎀
