Docker

I am trying to start databse by docker but it fails by saying that that port is already in use "Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:5432 -> 0.0.0.0:0: listen tcp 0.0.0.0:5432: bind: address already in use" But then i run - lsof -i :5432 It shows nothing. No other docker image or container is running.

does whatever you're doing work when you use another port?

DachiOP•2mo ago

i am just starting to learn all of these stuff and was following a tutorial and since i had this error was curious what was the reason and what can cause it

surf68•2mo ago

so what command are you using to start the container?

DachiOP•2mo ago

docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d

surf68•2mo ago

can you pastebin the contents of your compose files?

JohnStoober•2mo ago

Show your docker-compose.yml file

DachiOP•2mo ago

do what?

JohnStoober•2mo ago

Ok so You know that file

JohnStoober•2mo ago

Docker-compose.yml Yes Ok do you have any other files? Maybe a Dockerfile?

DachiOP•2mo ago

this is override

JohnStoober•2mo ago

Ok so try running docker ps Let us know the output

DachiOP•2mo ago

its empty

JohnStoober•2mo ago

Ehat command are you running to start the containers?

DachiOP•2mo ago

docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d

JohnStoober•2mo ago

And you arent running anything on your actual machine thats using port 5432?

DachiOP•2mo ago

no i checked it via lsof -i :5432 and it outputed nothing that's why i was confused

JohnStoober•2mo ago

DachiOP•2mo ago

we can call if it is better for you

JohnStoober•2mo ago

That is strange Unfortunately im at work

DachiOP•2mo ago

sure i am using mac if that changes anything

JohnStoober•2mo ago

Oh wait How are you running this? Vm?

DachiOP•2mo ago

rider

JohnStoober•2mo ago

Docker desktop?

DachiOP•2mo ago

rider has built in docker executor

JohnStoober•2mo ago

Brb

DachiOP•2mo ago

no, now i am trying to run it thru terminal by this command docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d

surf68•2mo ago

Does this work? docker run --rm -p 5432:80 nginx

DachiOP•2mo ago

surf68•2mo ago

alright, something on your machine is definitely already running on port 5432

DachiOP•2mo ago

yeah i guess it is jjust a waste of time. i've been debugging it for 2 days anyways thanks for the time

surf68•2mo ago

netstat -tuln | grep 5432 Does that highlight anything?

DachiOP•2mo ago

damn i hting you found it

surf68•2mo ago

that looks like it's a bit of a red herring

DachiOP•2mo ago

i will literally never forget that command thanks a lot ❤️

surf68•2mo ago

wait, you've fixed it? i think that's just a red herring. do you get any different output with lsof run as root? it could be another user has the port in use.

DachiOP•2mo ago

yeah i could fix it no i get nothing by running lsof

surf68•2mo ago

ok well if you've fixed it then all good 👍

DachiOP•2mo ago

my bad i could not fix it i think it is with the docker

surf68•2mo ago

try docker run --rm -p 17839:80 nginx i.e. some other random port that's very unlikely to be in use

DachiOP•2mo ago

is it suppose to take long?

surf68•2mo ago

the container should start up pretty quickly? visit http://localhost:17839 in your browser when it's started and you should see the nginx hello world

DachiOP•2mo ago

Dachis-MacBook-Pro:~ dachilekborashvili$ docker run --rm -p 17839:80 nginx docker: Error response from daemon: driver failed programming external connectivity on endpoint hopeful_gates (e777ca74d2296c695662ac9d30b4ae3d94d84b63040451a41508494bd9b27ead): Bind for 0.0.0.0:17839 failed: port is already allocated.

surf68•2mo ago

and you just ran that command the once?

DachiOP•2mo ago

i terminated the first one and ran again

surf68•2mo ago

do you get any output from docker ps?

DachiOP•2mo ago

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 62d69a2a3132 nginx "/docker-entrypoint.…" 5 minutes ago Up 5 minutes 0.0.0.0:17839->80/tcp hopeful_galileo

surf68•2mo ago

ok so the container is already running and bound to that port presumably that link i sent you works on your machine and shows you the nginx hello world page?

DachiOP•2mo ago

yes

surf68•2mo ago

okay, so you can kill and remove that container (docker rm -f 62d69a2a3132)

DachiOP•2mo ago

done i checked its killed

surf68•2mo ago

so your docker install seems to be working fine, you can spin up and bind ports for containers, it's just convinced that something else is already using port 5432

DachiOP•2mo ago

so i should just use another port cuz for some reason something is running on that port

surf68•2mo ago

if you can't find the culprit then yeah, i'd just use another port to get you going you could always restart your machine and see whether that frees up the port too if you haven't already tried that

DachiOP•2mo ago

i just simply changed port it is running @surf68@JohnStooberthanks both of you for your time and help
