When I run docker-compose up in my Docker project it fails with the following message:
Error starting userland proxy: listen tcp 0.0.0.0:3000: bind: address already in use
netstat -pna | grep 3000
shows this:
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN -
I've already tried docker-compose down, but it doesn't help.
In your case it was some other process that was using the port and as indicated in the comments, sudo netstat -pna | grep 3000 helped you in solving the problem.
While in other cases (I myself encountered it many times) it mostly is the same container running at some other instance. In that case docker ps was very helpful as often I left the same containers running in other directories and then tried running again at other places, where same container names were used.
How docker ps helped me:
docker rm -f $(docker ps -aq) is a short command which I use to remove all containers.
Edit: Added how docker ps helped me.
This helped me:
docker-compose down # Stop container on current dir if there is a docker-compose.yml
docker rm -fv $(docker ps -aq) # Remove all containers
sudo lsof -i -P -n | grep <port number> # List who's using the port
and then:
kill -9 <process id> (macOS) or sudo kill <process id> (Linux).

I had the same problem. I fixed this by stopping the Apache2 service on my host.
You can kill the process listening on that port easily with one command below :
kill -9 $(lsof -t -i tcp:<port#>)
ex :
kill -9 $(lsof -t -i tcp:<port#>)
or for ubuntu:
sudo kill -9 `sudo lsof -t -i:8000`
Man page for lsof : https://man7.org/linux/man-pages/man8/lsof.8.html
-9 is for hard kill without checking any deps.
(Not related, but might be useful if its PORT 5000 mystery) - the culprit process is due to Mac OS monterery.
The port 5000 is commonly used to serve local development servers. When updating to the latest macOS operating system, I was unable the docker to bind to port 5000, because it was already in use. (You may find a message along the lines of Port 5000 already in use.)
By running lsof -i :5000, I found out the process using the port was named ControlCenter, which is a native macOS application. If this is happening to you, even if you use brute force (and kill) the application, it will restart itself. In my laptop, lsof -i :5000 returns that Control Center is being used by process id 433. I could do killall -p 433, but macOS keeps restarting the process.
The process running on this port turns out to be an AirPlay server. You can deactivate it in
System Preferences › Sharing, and unchecking AirPlay Receiver to release port 5000.
I had same problem,
docker-compose down --rmi all (in the same directory where you run docker-compose up)
helps
UPD: CAUTION - this will also delete the local docker images you've pulled (from comment)
For Linux/Unix:
Simple search for linux utility using following command
netstat -nlp | grep 8888
It'll show processing running at this port, then kill that process using PID (look for a PID in row) of that process.
kill PID
In some cases it is critical to perform a more in-depth debugging to the problem before stopping a container or killing a process.
Consider following the checklist below:
1) Check you current docker compose environment
Run docker-compose ps. If port is in use by another container, stop it with docker-compose stop <service-name-in-compose-file> or remove it by replacing stop with rm.
2) Check the containers running outside your current workspace
Run docker ps to see list of all containers running under your host.
If you find the port is in use by another container, you can stop it with docker stop <container-id>.
(*) Because you're not under the scope of the origin compose environment - it is a good practice first to use docker inspect to gather more information about the container that you're about to stop.
3) Check if port is used by other processes running on the host
For example if the port is 6379 run:
$ sudo netstat -ltnp | grep ':6379'
tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 915/redis-server 12
tcp6 0 0 ::1:6379 :::* LISTEN 915/redis-server 12
(*) You can also use the lsof command which is mainly used to retrieve information about files that are opened by various processes (I suggest running netstat before that).
So, In case of the output above the PID is 915. Now you can run:
$ ps j 915
PPID PID PGID SID TTY TPGID STAT UID TIME COMMAND
1 915 915 915 ? -1 Ssl 123 0:11 /usr/bin/redis-server 127.0.0.1:6379
And see the ID of the parent process (PPID) and the execution command.
You can also run: $ pstree -s <PID> to a visual display of the process and its related processes.
In our case we can see that the process probably is a daemon (PPID is 1) - In that case consider running: A) $ cat /proc/<PID>/status in order to get a more in-depth information about the process like the number of threads spawned by the process, its capabilities, etc'.
B) $ systemctl status <PID> in order to see the systemd unit that caused the creation of a specific process. If the service is not critical - you can stop and disable the service.
4) Restart Docker service
Run: sudo service docker restart.
5) You reached this point and..
Only if its not placing your system at risk - consider restarting the server.
In my case it was
Error starting userland proxy: listen tcp 0.0.0.0:9000: bind: address already in use
And all that I need is turn off debug listening in php storm
Most probably this is because you are already running a web server on your host OS, so it conflicts with the web server that Docker is attempting to start.
So try this one-liner before trying anything else:
sudo service apache2 stop; sudo service nginx stop; sudo nginx -s stop;
I had apache running on my ubuntu machine. I used this command to kill it!
sudo /etc/init.d/apache2 stop
I was getting the below error when i was trying to launch a new container -
listen tcp 0.0.0.0:8080: bind: address already in use.
To check which process is running on port 8080, run below command:
netstat -tulnp | grep 8080
i got the output below
[root#ip-112-x6x-2x-xxx.xxxxx.compute.internal (aws_main) ~]# netstat -tulnp | grep 8080 tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN **12749**/java [root#ip-112-x6x-2x-xxx.xxxxx.compute.internal (aws_main) ~]#
run
kill -9 12749
Then try to relaunch the container it should work
If redis server is started as a service, it will restart itself when you using kill -9 <process_id> or sudo kill -9 `sudo lsof -t -i:<port_number>` . In that case you will need to stop the redis service using following command.
sudo service redis-server stop
I upgraded my docker this afternoon and ran into the same problem. I tried restarting docker but no luck.
Finally, I had to restart my computer and it worked. Definitely a bug.
Check docker-compose.yml, it might be the case that the port is specified twice.
version: '3'
services:
registry:
image: mysql:5.7
ports:
- "3306:3306" <--- remove either this line or next
- "127.0.0.1:3306:3306"
Changing network_mode: "bridge" to "host" did it for me.
This with
version: '2.2'
services:
bind:
image: sameersbn/bind:latest
dns: 127.0.0.1
ports:
- 172.17.42.1:53:53/udp
- 172.17.42.1:10000:10000
volumes:
- "/srv/docker/bind:/data"
environment:
- 'ROOT_PASSWORD=secret'
network_mode: "host"
I ran into the same issue several times. Restarting docker seems to do the trick
A variation of #DmitrySandalov's answer: I had tomcat/java running on 8080, which needed to keep going. Looked at the docker-compose.yml file and altered the entry for 8080 to another of my choosing.
nginx:
build: nginx
ports:
#- '8080:80' <-- original entry
- '8880:80'
- '8443:443'
Worked perfectly. (The only wrinkle is the change will be wiped if I ever update the project, since it's coming from an external repo.)
At first, make sure which service you are running in your specific port. In your case, you are already using port number 3000.
netstat -aof | findstr :3000
now stop that process which is running on specific port
lsof -i tcp:3000
I resolve the issue by restarting Docker.
It makes more sense to change the port of the docker update instead of shutting down other services that use port 80.
Just a side note if you have the same issue and is with Windows:
In my case the process in my way is just grafana-server.exe. Because I first downloaded the binary version and double click the executable, and it now starts as a service by user SYSTEM which I cannot taskkill (no permission)
I have to go to "Service manager" of Windows and search for service "Grafana", and stop it. After that port 3000 is no longer occupied.
Hope that helps.
The one that was using the port 8888 was Jupiter and I had to change the configuration file of Jupiter notebook to run on another port.
to list who is using that specific port.
sudo lsof -i -P -n | grep 9
You can specify the port you want Jupyter to run uncommenting/editing the following line in ~/.jupyter/jupyter_notebook_config.py:
c.NotebookApp.port = 9999
In case you don't have a jupyter_notebook_config.py try running jupyter notebook --generate-config. See this for further details on Jupyter configuration.
Before it was running on :docker run -d --name oracle -p 1521:1521 -p 5500:5500 qa/oracle
I just changed the port to docker run -d --name oracle -p 1522:1522 -p 5500:5500 qa/oracle
it worked fine for me !
On my machine a PID was not being shown from this command netstat -tulpn for the in-use port (8080), so i could not kill it, killing the containers and restarting the computer did not work. So service docker restart command restarted docker for me (ubuntu) and the port was no longer in use and i am a happy chap and off to lunch.
maybe it is too rude, but works for me. restart docker service itself
sudo service docker restart
hope it works for you also!
I have run the container with another port, like... 8082 :-)
I came across this problem. My simple solution is to remove the mongodb from the system
Commands to remove mongodb in Ubuntu:
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev
sudo apt-get purge mongodb-10gen
sudo apt-get autoremove
Let me add one more case, because I had the same error and none of the solutions listed so far works:
serv1:
...
networks:
privnet:
ipv4_address: 10.10.100.2
...
serv2:
...
# no IP assignment, no dependencies
networks:
privnet:
ipam:
driver: default
config:
- subnet: 10.10.100.0/24
depending on the init order, serv2 may get assigned the IP 10.10.100.2 before serv1 is started, so I just assign IPs manually for all containers to avoid the error. Maybe there are other more elegant ways.
I have the same problem and by stopping docker container it was resolved.
sudo docker container stop <container-name>
i solved with this sudo service redis-server stop

I'm on a Windows Ten Box, running Docker Version 17.09.0-ce-win33 (13620).
I do something like this. docker run --rm -p 1001:8787 rocker/rstudio
however if quit the docker, and try to rerun it with the same port it fails because its still open. Running netstat its still "listening" on the same port.
[vpnkit.exe]
TCP [::1]:1001 WN-10DT:0 LISTENING
My question is can I reuse the port without having to restart?
thanks in advance.
I use following commands to run my project.
docker run -it -p 8080:80 --rm -v "d:\project1:/var/www/html" myimage....
This was running fine till yesterday. But when I tried the same command, I am getting error
docker: Error response from daemon: failed to create endpoint loving_dubinsky on network nat: hnsCall failed in Win32: The specified port already exists. (0x803b0013).
I checked if 8080 port is being used or not using following command.
netstat -ano | findstr :8080
I could not see this port is being used.
How can I fix this issue?
Thank You.
Run "docker ps" command.
From "docker ps" output, you will come to know if there is any container which is listening to port 8080.
You can kill that container using "docker kill container_id".
Now your port 8080 will be free.
I have a server running on port 80, but I do not know what it is or where it came from. When I run
sudo lsof -i :80 | grep LISTEN
I get
httpd 80 root 5u IPv6 0x91f5a9de62859cfd 0t0 TCP *:http (LISTEN)
httpd 694 _www 5u IPv6 0x91f5a9de62859cfd 0t0 TCP *:http (LISTEN)
I have tried to enter get the process name using the PID, but all I ever get in return is "httpd" or "FOREGROUND".
When I kill the PID, the process simply restarts with a new PID. I assume I will have to stop it at launch.
How can I stop this server from running at startup?
If it helps any, I am trying to free up port 80 to use the apache server on MAMP.
This is just a guess, but it might be the built-in version of apache, being launched (& restarted) by launchd (OS X's daemon manager). It's disabled by default, but might've gotten enabled somehow. You can try disabling it with:
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
If that doesn't do it (it'll say something like "Could not find specified service"), you can check to see if it's some other launch daemon item by looking for the PID of the master process (the one running as root, not _www):
sudo launchctl list | grep <masterPID>
That won't necessarily tell you exactly what's going on, but might point you in the right direction.
Like Gordon suggested, that's the built-in version of the Apache web server.
You can stop it with
sudo apachectl stop
btw, the configuration for this webserver can be found in the /etc/apache2/httpd.conf directory.
This happens to me a lot.
As #Gordon Davisson explains it is most likely the launchdeamon process conflicting with the service you have set up.
Definitely stop the apachetl server.
sudo apachetl -k stop
Try to find all the httpd process, they should be the last ones
sudo lsof -i :80 // without grep
Then get the first process (most likely in the 1000s) should also be the lowest one.
sudo kill <firstHttpdPID>
This should kill ALL the processes running that httpd instance and then you get simply start back up your server.
Must stop it first though or it will continue running again.
Mac OSX comes bundled with Apache, however it is deactivated. You might have activated it somehow. In my case, I have previously install XAMPP and configured something in the /etc/apache2/httpd.conf that leads my port localhost:80 to leads to html page with It Works!.
TLDR, the solution is to deactivate the Apache2 server.
Go to your terminal, and type this
sudo apachetl -k stop
In my case, it returns the following:
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using Shafies-MacBook-Pro.local. Set the 'ServerName' directive globally to suppress this message
httpd (no pid file) not running
if you typed localhost on your browser, the port 80 is not active anymore and you will not see It Works! anymore.
For context, I have deleted XAMPP long time ago and not aware that my localhost:80 is still active. I am not able redirect dummy domain -- posts.com to my localhost port for my kubernetes YAML config files.
This is my ingress-srv.yaml file:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: ingress-srv
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: 'true'
spec:
rules:
- host: posts.com
http:
paths:
- path: /?(.*)
backend:
serviceName: client-srv
servicePort: 3000
and I have tricked the operating system to redirect my posts.com to localhost:80 by adding below line in the hosts file located at /etc/hosts
127.0.0.1 posts.com

In my current job we have development environment made with docker-compose.
One container is nginx, which provide routing to other containers.
Everything seems fine and work to my colleague on windows and osx. But on my system (osx El Capitan), there is problem with accessing nginx container on port 80.
There is setup of container from docker-compose.yml
nginx:
build: ./dockerbuild/nginx
ports:
- 80:80
links:
- php
volumes_from:
- app
... and more
In ./dockerbuild/nginx there is nothing special, just nginx config as we know it from everywhere.
When I run everyting with docker-compose create and docker-compose start. Then docker ps give me
3b296c1e4775 docker_nginx "nginx -g 'daemon off" About an hour ago Up 47 minutes 0.0.0.0:80->80/tcp, 443/tcp docker_nginx_1
But when I try to access it for example via curl I get error. curl: (7) Failed to connect to localhost port 80: Connection refused
I try to run container with port 81 and everything works fine.
Port is really binded to docker
22:47 $ sudo lsof -i -n -P | grep TCP
...
com.docke 14718 schovi 38u IPv4 0x6e9c93c51ec4b617 0t0 TCP *:80 (LISTEN)
...
Firewall in osx is turned off and I have no other security.
if you are using docker-for-mac:
Accessing by localhost:80 is correct, though you still have to ensure you do not have a local apache/nginx service running. Often leftovers from boxen/homebrew exist binding that port, because thats what developers did back then :)
if you are using dockertoolbox/virtualbox/whatever hypervisor
You will not be able to access it by localhost, by by the docker-machine ip, so write docker-machine ip default and the use http://$ip:80 in your browser
if that does not help
Ensure your nginx container actually does work, so connect to the container: docker exec -i -t <containerid> bash
and then run ps aux nginx or if telnet is installed try to connect to localhost
Solved!
Problem was, that long long time ago I installed pow (super simple automated rails server which run application on app_name.local domain). And this beast left LaunchAgent script which update pf to forward port 80 to pow port.
In my current job we have development environment made with docker-compose.
A privilege to use.
[W]hen I try to access [nginx on port 80] for example via curl I get error.
Given there's nothing from causing you from accessing docker on your host os you should look at the app running inside the container to ensure it's binding to the correct host, e.g. 0.0.0.0 and not localhost.
For example, if you're running Nuxt inside a container with nuxt-ts observe Nuxt will default to localhost thereby causing the container not to connect to the docker network whereas npx nuxt-ts -H 0.0.0.0 gets things squared away with the container's internal server connecting to the ip of the docker network used (verify ip like docker container inspect d8af01990363).
Problem
I'm trying to start postgres in a docker container on my Mac, but I keep getting the following error message
docker: Error response from daemon: driver failed programming external connectivity on endpoint postgres (8392b9e5cfaa28f480fe1009dee461f97e82499726f4afc4e916358dd2d2f61e): Error starting userland proxy: Failed to bind tcp 0.0.0.0:5432 address already in use.
I have postgres installed locally, but I stopped it and running
pg_ctl status
returns
pg_ctl: no server running
I've ran the following to check what's running on 5432
lsof -i tcp:5432
&
netstat -anp tcp | grep 5432
and nothing is running on the port.
Versions
Mac - OS X El Capitan Version 10.11.2
PostgreSQL - 9.5
Docker - Docker version 1.12.0-rc2, build 906eacd, experimental
If lsof -i :5432 doesn't show you any output, you can use sudo ss -lptn 'sport = :5432' to see what process is bound to the port.
Proceed further with kill <pid>
If you execute lsof -i :5432 on the host you can see what process is bound to the port.
Some instance of Postgres is running. You can execute kill <pid> to kill it if you want. You can also use 5432 instead of 5432:5432 in your docker command or docker-compose file and let docker choose the host port automatically.
The first thing you should do is stop PostgreSQL service.
In most cases it fixed the issue.
sudo service postgresql stop
If above doesn't work. then add the following line to /etc/postgresql/12/main/postgresql.conf
sudo vim /etc/postgresql/12/main/postgresql.conf
## good if you add under CONNECTION AND AUTHENTICATION comments
listen_addresses = "*"
macOS Monterey
None of the above commands worked for me - need to do few changes. So, adding the complete working solution:
Identify what is running in port 5432: sudo lsof -i :5432
Kill all the processes that are running under this port: sudo kill -9 <pid>
Run the command again to verify no process is running now: sudo lsof -i :5432
it is worked for me, probably you should stop postgres :
sudo systemctl stop postgresql
In some cases it is critical to perform a more in-depth debugging to the problem before stopping or killing the container/process.
Consider following the checklist below:
1) Check you current docker compose environment
Run docker-compose ps. If port is in use by another container, stop it with docker-compose stop <service-name-in-compose-file> or remove it by replacing stop with rm.
2) Check the containers running outside your current workspace
Run docker ps to see list of all containers running under your host.
If you find the port is in use by another container, you can stop it with docker stop <container-id>.
(*) Because you're not under the scope of the origin compose environment - it is a good practice first to use docker inspect to gather more information about the container that you're about to stop.
3) Check if port is used by other processes running on the host
For example if the port is 6379 run:
$ sudo netstat -ltnp | grep ':6379'
tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 915/redis-server 12
tcp6 0 0 ::1:6379 :::* LISTEN 915/redis-server 12
(*) You can also use the lsof command which is mainly used to retrieve information about files that are opened by various processes (I suggest running netstat before that).
So, In case of the output above the PID is 915. Now you can run:
$ ps j 915
PPID PID PGID SID TTY TPGID STAT UID TIME COMMAND
1 915 915 915 ? -1 Ssl 123 0:11 /usr/bin/redis-server 127.0.0.1:6379
And see the ID of the parent process (PPID) and the execution command.
You can also run: $ pstree -s <PID> to a visual display of the process and its related processes (install with: brew install pstree).
In our case we can see that the process probably is a daemon (PPID is 1) - In that case consider running: A) $ cat /proc/<PID>/status in order to get a more in-depth information about the process like the number of threads spawned by the process, its capabilities, etc'.

4) Restart Docker service
Run sudo service docker restart.
5) You reached this point and..
Only if its not placing your system at risk - consider restarting the server.
None of these other answers worked for me. (For example, lsof and netstat just returned empty lines.) The following worked, though:
sudo -u postgres pg_ctl -D /Library/PostgreSQL/13/data stop
In case of mac,
if you are OK with uninstalling the POSTGRES for the time being:
brew uninstall postgres
Then check if the process still exists
sudo lsof -nP -i4TCP:5432 | grep LISTEN
If it exists, then kill it
kill -9 <pid>
Check again if the 5432 is being listened at, this time it should not be.
