I am using docker for the first time and I was trying to implement this - https://docs.docker.com/get-started/part2/#tag-the-image

At one stage I was trying to connect with localhost by this command -

$ curl http://localhost:4000

which showed this error-

curl: (7) Failed to connect to localhost port 4000: Connection refused

However, I have solved this by following code -

$ docker-machine ip default
$ curl http://192.168.99.100:4000

After that everything was going fine, but in the last part, I was trying to run the app by using following line according to the tutorial...

$ docker run -p 4000:80 anibar/get-started:part1

But, I got this error

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint goofy_bohr (63f5691ef18ad6d6389ef52c56198389c7a627e5fa4a79133d6bbf13953a7c98): Bind for 0.0.0.0:4000 failed: port is already allocated.

It seems the port is allocated, so can you please help me by informing how I can solve this.. Thanks a lot :)

You need to make sure that the previous container you launched is killed, before launching a new one that uses the same port.

docker container ls
docker rm -f <container-name>

port is already allocated without running containers · Issue #205 , Cannot start containers: port is already allocated moby/moby#20486 Port 8080 conflict after recent update of Docker #670 The only way I can get around this is using a different port: "-p 0.0.0.0:4000:3000 -p 0.0.0.0:4001:3001". userland proxy: Bind for 0.0.0.0:8091 failed: port is already allocated. This doesn’t seem to agree with the way Docker works. a fast startup simply loads the hibernation file (Hiberfil.sys) into memory to restore the previously saved image of the Windows kernel and

Paying tribute to IgorBeaz, you need to stop running the current container. For that you are going to know current CONTAINER ID:

$ docker container ls

You get something like:

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                  NAMES
12a32e8928ef        friendlyhello       "python app.py"     51 seconds ago      Up 50 seconds       0.0.0.0:4000->80/tcp   romantic_tesla   

Then you stop the container by:

$ docker stop 12a32e8928ef

Finally you try to do what you wanted to do, for example:

$ docker run -p 4000:80 friendlyhello

Docker-compose up failing because "port is already allocated , I don't believe I have another container running so I'm confused by the message Bind for 0.0.0.0:5432 failed: port is already allocated  Under PORT you’ll see a mapping of the HOST PORT (0.0.0.0:8000) -> CONTAINER PORT (8000/tcp). The port from your failure will be on one of the containers. Make a note of the CONTAINER ID and run docker stop <CONTAINER ID>. If you no longer need the container, run docker rm <CONTAINER ID> to clean it up.

Above two answers are correct but didn't work for me.

  1. I kept on seeing blank like below for docker container ls
  2. then I tried, docker container ls -a and after that it showed all the process previously exited and running.
  3. Then docker stop <container id> or docker container stop <container id> didn't work
  4. then I tried docker rm -f <container id> and it worked.
  5. Now at this I tried docker container ls -a and this process wasn't present.

How to Use Docker Compose to Run Multiple Instances of a Service , Because the host machine can only bind an unallocated port to the container, we will get the Bind for 0.0.0.0:5000 failed: port is already allocated error for each  Hello, I have followed step bu step the "README.md", i ran the docker image in this way: sudo docker run -i -t -d -p 8080:80 onlyoffice/documentserver But when i get to "Configuring Docker Image" part: sudo docker run -i -t -d -p 8080:80

I solved it this way:

First, I stopped all running containers:

docker-compose down

Then I executed a lsof command to find the process using the port (for me it was port 9000)

sudo lsof -i -P -n | grep 9000

Finally, I "killed" the process (in my case, it was a VSCode extension):

kill -9 <process id>

I had a slightly different situation, posting here to record another case of this happening. When using a docker-compose.yml and docker-compose.override.yml file, which both contain a port mapping, where the host port is the same for both mappings, but the container port differs, then this causes docker to try and allocate the host port twice.

Stopping the container didn't work for me either. I changed the port in docker-compose.yml.

  • Even after removing all the dockers from archive (-a) option , I still get this error Error starting userland proxy: Bind for 0.0.0.0:8080 failed: port is already allocated.
  • Perhaps something else is occupying this port. Find out and if not necessary kill the process and your port will be free.
  • Following the advice of yamenk's accepted answer showed no containers in use. This answer helped me to track down the process using the port. If this answer contained information for checking active docker contains as well then it should be the accepted answer. "port is already allocated" does not always mean "docker container is already running"
  • This did it! Thanks for the tip!
