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 created a topic with replica=2 in kafka, and kafka is running in my docker machine.
Usually, I should be able to connect to docker with port 9092. but I can't
While, I am able to connect using 32783. Not sure what's the reason?
It's the Docker run command (which is not shown in the question). 9092 internally is being mapped out to 32783,32784,32785. I am guessing the three docker run commands were -p 32783:9092 etc.
You should run it with -p 9092:9092 if you want it to be 9092 on your local machine.
On my Mac, I run Kafka in a container like this (note ADVERTISED_HOST env var):
docker run --name st-kafka -p 2181:2181 -p 9092:9092 --add-host=dockerhost:`docker-machine ip dev-st` -e ADVERTISED_HOST=`docker-machine ip dev-st` -e ADVERTISED_PORT=9092 -d spotify/kafka
I like spotify/kafka because it contains both ZK and Kafka in the same container (nice for local dev environment). The latest version is 0.8.2 I think, so you should use a different image or make your own Dockerfile with version 0.9, if that's the one you need.
I've set up an Ubuntu 14.04 AWS instance. My security group has port 8888 open (tcp), and port 22 open for ssh.
I can ssh into the instance just fine, then in the instance I start a docker container:
docker run -it --name="test" -p 8888:9999 b.gcr.io/tensorflow/tensorflow:latest-devel
This container has jupyter notebook in it, then in the container I run jupyter notebook and I see the correct output:
[I 14:49:43.788 NotebookApp] The Jupyter Notebook is running at: http://[all ip addresses on your system]:8888/
[I 14:49:43.788 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
And if I run docker ps by opening another ssh, connection I see:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8414f19fcd5f b.gcr.io/tensorflow/tensorflow:latest-devel "/bin/bash" 38 minutes ago Up 23 minutes 6006/tcp, 8888/tcp, 0.0.0.0:8888->9999/tcp test
So everything seems correct, but I do not see jupyter notebook at: http://PUBLICIP:8888
Instead of:
docker run -it --name="test" -p 8888:9999 b.gcr.io/tensorflow/tensorflow:latest-devel
The trick was to use:
docker run -it --name="test" -p 8888:8888 b.gcr.io/tensorflow/tensorflow:latest-devel
Edit, thanks to DDW for the explanation:
"-p 8888:9999 doesn't stand for a range, it means port 9999 of your docker container is mapped to port 8888. 8888 is probably your standard notebook port, so it is logical that 8888:8888 works."
If you want to have two ports open then the command would be:
docker run -it --name="test" -p 8888:8888 -p 9999:9999 b.gcr.io/tensorflow/tensorflow:latest-devel
In my case the solution was to add --network="host" to docker run command
However it comes with some other effects be aware.
You can checkout from
https://docs.docker.com/network/host/#:~:text=If%20you%20use%20the%20host,its%20own%20IP%2Daddress%20allocated

Because I think , it is a docker network problem.
I think I am missing something obvious but I can't seem to crack this one. I am trying to map a port from a django application running uwsgi in a docker container to my local Macintosh host. Here is the setup.
Mac 10.11 running docker-machine 0.5.1 with virtualbox 5.0.10 and docker 1.9.1
I created a server with docker-machine setup my docker file and successfully built my docker container. In the container I have the following command
# Port to expose
EXPOSE 8000
Which maps to the port used via uwsgi inside the container. When I runt he container via
eval "$(docker-machine env dev)"
docker-machine ip dev
192.168.99.100
docker run -P launch
The container starts properly. If I enter the container and perform a
curl http://localhost:8000
I get my HTML as I would expect. On the outside a docker inspect container_id gets me a
"Ports": {
"8000/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "32768"
}
]
},
So i can see the mapping to 32768 on the docker-machine host of 192.168.99.100 as from the above commands. However whenever I try and curl http://192.168.99.100:32768
curl http://192.168.99.100:32768
curl: (7) Failed to connect to 192.168.99.100 port 32768: Connection refused
So any thoughts on this?? Everything should work as I understand docker.
Thanks
Craig
Since you are running through a VirtualBox VM, I would still recommend mapping the port on the VirtualBox level, as I mention in "How to connect mysql workbench to running mysql inside docker?"
VBoxManage controlvm "boot2docker-vm" --natpf1 "tcp-port8000 ,tcp,,8000,,8000"
VBoxManage controlvm "boot2docker-vm" --natpf1 "udp-port8000 ,udp,,8000,,8000"
And run the container with an explicit port mapping (instead of the random -P)
docker run -p 8000:8000 launch
I'm using boot2docker on OSX 10.10 to try to run the WSO2 governance registry. I cannot reach the app from the host machine (OSX).
Here's my Dockerfile:
FROM dockerfile/java:openjdk-7-jdk
MAINTAINER Andrew Matthews
COPY wso2greg-4.6.0.zip /opt/
RUN unzip /opt/wso2greg-4.6.0.zip -d /opt && \
rm /opt/wso2greg-4.6.0.zip
EXPOSE 9443
CMD ["/opt/wso2greg-4.6.0/bin/wso2server.sh"]
This follows a pattern used by others on docker.io for other wso2 apps.
I built it with:
docker build -t="usmsnp/wso2greg" .
and ran it with
docker run -i -t -P usmsnp/wso2greg
everything seems to proceed nicely - I get as far as the wso2 announcement:
Mgt Console URL : https://172.17.0.27:9443/carbon/
I have the boot2docker vm IP address aliased as dockerhost in my /etc/hosts file, and when I navigate to https://dockerhost:9443/carbon/ using curl I get connection refused.
Any ideas?
UPDATE: 2014-11-28
When I deploy the image to AWS using tutum, it works. So, mission accomplished, I suppose. But I'm still confused about why it doesn't work. I understand that boot2docker requires a different IP address, but I used that.
When you use docker run -P you're telling Docker to allocate a random port on the Docker daemon host - not to use 9443.
So in this case, you'll need to run docker ports <containerid> to find out what port its been mapped to.
alternativly, you need to use docker run -p 9443:9443 ... to tell Docker to map the external 9443 to the container's 9443
