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 am beginner of spring boot. when i run the spring boot application i ran into the problem with The Tomcat connector configured to listen on port 8080 failed to start. Spring boot
i don't how to solve the problem. i have install mysql when i ran the mysql it port also 8080. so how to sort out the problm.
***************************
APPLICATION FAILED TO START
***************************
Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.
Seems like 8080 port is already used by some other process.
Change the port of spring-boot tomcat port by adding the server.port=8090 in application.properties.
Change 8090 to any port you want to use.
Your 8080 port is already used by some other process.
Change the port of spring-boot server.port=8090 in application.properties.
You can change your application run server port any port number to if that port number would not belong to any other process on your computer.
and another thing if you use IntelliJ idea to develop, accidentally close your IDE without proper way this error may have occurred {personal experience}.
It is not necessarily required to change the port, you can just end the process of it to release it in your spring application
Open cmd as administrator and enter the following commands:
netstat -year | findstr 9330
Once you find the process number, type it in the highlight of the following command:
taskkill /F /PID <Process ID>
The result should appear as follows:
SUCCESS: The process with PID < Process Id > has ended.
I have created a Google compute instance with Container-optimized-OS image.
I have configured the firewall to allow http and https.
I am using the docker image with spring boot application which connects to cloudsql. When I use run command on compute engine instance ssh, i.e. (docker run --rm name), the spring boot app is started successfully.
When I try to access the webservices through compute engine instance external ip, it is not working.
I went through a different question, and found that I should try using the sudo wget http://localhost command on the instance cli first and if it is good then everything should be good. But I am getting a connection refused message on 127.0.0.1:80.
I also tried the command to open port from Container optimized OS, I.E.
sudo iptables -w -A INPUT -p tcp --dport 80 -j ACCEPT , nothing is working.
The default port for Spring Boot is 8080 and not 80.
Run this command inside the instance container to see what ports are in LISTENING state:
sudo netstat -tulpn | grep LISTEN
You can redirect port 80 to port 8080 with this command:
sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
Note: This iptables command only redirects port 80 to 8080 on network interfaces. This has no effect for localhost or 127.0.0.1.
For Google Compute Engine instances you do not need to enable ports using iptables. This is done via Google VPC firewall rules. You can use both but make sure you understand exactly what you are configuring and the side effects.
Note: Your Spring Boot application needs to listen on 0.0.0.0 and not 127.0.0.1 nor localhost. The last two are internal only addresses. 0.0.0.0 means listen on all network interfaces.
Note: Do not use sudo in front of wget. This is not necessary.
First, confirm what port your springboot application uses - if it's 8080 or 80. This depends on what you have configured inside application.properties file. This port is referred to as ContainerPort in below steps.
Execute docker run <image-name>:<tag>. This will run the image and show container logs on the console. If there is something wrong with your spring-boot app, the logs will show that and the container will shutdown. Press Ctrl+C to stop the container and return to shell.
If there is no error in step 1 run docker run -d -p<HostPort>:<ContainerPort> <image-name>:<tag>. Here HostPort is any free port in your GCP host VM and ContainerPort is the port used by your spring boot application within the container. Option d starts your container in detached mode.
Run docker ps and make sure that the container started in step 2 is running. It may not run if there is an error - for example if the HostPort you specified is already in use.
If step 3 shows that the container is running, execute curl http://localhost:<HostPort>/<End-Point-Path>. Here End-Point-Path is a valid path to a working endpoint within the container. If the endpoint is correct you should see expected result from the spring-boot app in the console.
Navigate to Google Cloud Console -> VPC network -> Firewall rules and add a firewall rule to open HostPort on your GCP VM.
Access your endpoint via the VM's external IP with URL - http://<VM-External-IP>:<HostPort>/<End-Point-Path>
Unless there is an application issue with your spring-boot app these steps should get you going.
I was able to build the correct solution by your help (John Hanley and Cyac).
I am combining both solutions in order to help the next person facing this.
As told by John, by default Spring boot uses port 8080, not 80 and as specified by Cyac you need to specify the port as 80 explicitly in application.properties file using
server.port=80
Make sure you expose the port 80 in docker image
On GCP Contaier optimized OS make sure you have allowed traffic for HTTP and HTTPs
Run command:
sudo iptables -w -A INPUT -p tcp --dport 80 -j ACCEPT
Run docker using:
docker run -p 80:80 SPRING_IMAGE.
Where SPRING_IMAGE is the name of the docker image with spring boot build.
Test by using curl http://localhost/ENDPOINT_NAME , e.g. http://localhost/shops/all
Unable to run my project
I am just learning Springboot, following instruction from internet I set up a new project, I use Eclipse Oxygen + Maven (with Embedded Tomcat) + Springboot , I followed the instruction to run the project, but got following error message. I changed the port many times by revising "application.properties" file, but it didn't work. I checked all the ports, their states are "listening".
2019-07-03 04:04:16.256 ERROR 16132 --- [ main] org.apache.catalina.util.LifecycleBase : Failed to start component [Connector[HTTP/1.1-17500]]

APPLICATION FAILED TO START
Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
confirm To you can not use Same Port "8080" More Then One Application And also confirm to another application is not using same port
(Example:- you are going to run your application on Spring with Port 8080 and in Background Another application already was allocated port like XAMPP OR WAPP)
Check Listening Port
Make sure that new port you are going to set is not being used by
other processes. You can check the listening port as below
After Changing the port, Close and Reopen the Project and do Clean, Rebuild your
Project.
PowerShell
Get-Process -Id (Get-NetTCPConnection -LocalPort portNumber).OwningProcess
cmd
C:\> netstat -a -b
Solution
Kill Process on Port 8080 from cmd
netstat -ano | findstr :<yourPortNumber>
taskkill /PID <typeyourPIDhere> /F
OR Change the Port
Update via a properties file.
server.port=8888 # Server HTTP port.
Update via a yaml file.
server:
port: 8888
