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).

Source: comment by user Rub21.

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.

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.

I had apache running on my ubuntu machine. I used this command to kill it!

sudo /etc/init.d/apache2 stop

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;

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

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 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

[[email protected] (aws_main) ~]# netstat -tulnp | grep 8080 tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN **12749**/java [[email protected] (aws_main) ~]#

run

kill -9 12749

Then try to relaunch the container it should work

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"

Here’s yet another answer because it’s the only thing that worked for me.

REFERNENCE: /a/61888620/2027793

I ran this and kept seeing 3 php-fpm services running and listening on port 9000

sudo lsof -i -P -n | grep 9000

If then tried killing all the services, which kept restarting themselves automatically…

sudo kill -9 <process_id>
sudo pkill <process_name>

I decided that since I couldn’t kill the beast, I might as well play along with it and figure out how to change the port it was using, which is where I stumbled on the answer referenced above. You find the directory where your php is running.

cd /usr/local/etc/php/<php_version#>/php-fpm.d/

Edit the config file

vi www.conf

Find the line with this and change the port number

listen = 127.0.0.1:9000

Now repeat the find and kill actions above and then proceed to get your docker containers starting up again like they should.

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.

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.)

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"

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.

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.

It makes more sense to change the port of the docker update instead of shutting down other services that use port 80.

In my case, the issue was that I was running the MongoDB as a root user, and stopping that did the trick.

sudo brew services stop mongodb-community

For Windows users. This advice from official docker GitHub helped me.

net stop winnat
docker-compose up ...
net start winnat

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
