I am trying to use nginx on docker for windows using
docker container run --publish 80:80 nginx
it is getting the error like below:
C:\Program Files\Docker\Docker\resources\bin\docker.exe: Error response from daemon: Ports are not available: listen tcp 0.0.0.0:80: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
can anyone give me the solution......
As you can see the error is clear Ports are not available: listen tcp 0.0.0.0:80: because the port is occupied. you have two option
Kill the process the occupied the port and then run the container
Publish different port then 80 for the Nginx contianer
container run --publish 81:80 nginx then localhost:81
Now open http://localhost:81 should work.

I try to deploy self hosted Bitwarden service: https://bitwarden.com/help/article/install-on-premise/
When I run install script I get the following error:
docker: Error response from daemon: driver failed programming external connectivity
on endpoint certbot
(393789b88f2a15db0ae5fb0d3fdce83e14bd4d4eb890ffff0f946dc607953815): Error starting
userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use.
ERRO[0000] error waiting for container: context canceled
Which is expected because I already have NGINX on this VM with a couple of websites and port 80 is being used by the host.
I heard that is is possible to make docker container use another host port, instead of 80. That is container will have port 80, but it will be something else externally on the host. I tried to change the mapping in the install script like 5000:80 instead of 80:80 but I keep getting the same error.
Am I doing something wrong, or what I am trying to do is not possible?
You can add range to the command and it will use the first available port.
so -p 80-100:80.
TO get the port that your actually mapping to use docker ps and it will show you what port it's mapped to.
docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/runtime:3.1
docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/sdk:3.1
docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/aspnet:3.1
When I run any of the above docker commands to create a container, I get the following error. And I get this for both for linux as well as windows.
C:\Program Files\Docker\Docker\resources\bin\docker.exe: Error response from daemon: Ports are not available: listen tcp 0.0.0.0:8080: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
time="2020-03-24T17:20:44+05:30" level=error msg="error waiting for container: context canceled"
I tried the suggestion given in this SO ans to find the process Id and kill it.
Further I got the process hacker as suggested here to observe whats that process. Looks like its a system process.
Can anybody suggest what can be done?
-p 8080:80 says "forward port 8080 on the host to port 80 in the container". Port 80 is determined by the container image. Port 8080 is arbitrary—it's a port you're choosing.
So instead do -p 8081:80, and now you point your browser at localhost:8081 instead of localhost:8080.
If that doesn't work then maybe it's your firewall?
(See https://pythonspeed.com/articles/docker-connection-refused/ for diagrams of how port forwarding works).
You assign the same host port 8080 multiple times, which is not allowed - on any operating system.
After running this command
docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/runtime:3.1
the first container gets immediately the port 8080 assigned on the host machine, what we can also see in the console screenshot that you provided. And others fail, because they simply don't get the port they want. So that all containers can be started, you should use a different port for each container, a la
docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/runtime:3.1
docker run --rm -it -p 8081:80 mcr.microsoft.com/dotnet/core/sdk:3.1
docker run --rm -it -p 8082:80 mcr.microsoft.com/dotnet/core/aspnet:3.1
You should then be able to access those containers via the respective ports 8080, 8081, and 8082 (on localhost or local network IP of ur machine, e.g. 192.168.1.20).
This answer solves two errors I believe.
Error 1 (if the wrong port is specified in the Windows Defender Firewall for an existing rule for Docker):
Unable to find image 'docker102tutorial:latest' locally docker: Error
response from daemon: pull access denied for docker102tutorial,
repository does not exist or may require 'docker login': denied:
requested access to the resource is denied.
Error 2 (if no Windows Defender Firewall rule at all and #:8080 is specified in docker run command in the -p parameter):
Error response from daemon: Ports are not available: listen tcp
0.0.0.0:8080: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
In Windows 10, you will need to allow this through the Windows Defender Firewall. You'll get this dialog. You might be able to restrict the port for either the TCP by default (or UDP) line in the Windows Defender Firewall. The table screen shot of rules was taken before the port was modified and the last error was corrected. I believe the client in this case is WSL 2 and the server is Windows which means the incoming port needs to be opened on the server.
Allow Local Port 8080 in the Windows Defender Firewall so it matches the port after the ":" in the run command:
You will then get this error.
To correct, change from "Defer to user" to "Defer to application"
You can assign external port in the following ways:
Add an EXPOSE instruction in the Dockerfile such as EXPOSE 8080
Use the –expose flag at runtime to expose a port like the following: docker -expose=8080 test
Use the -p flag or -P flag in the Docker run string to publish a port as mentioned above, i.e. docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/core/runtime:3.1
But you are allowed to do it only ONCE
Open PowerShell in administrator mode and enter the command
net stop http
The command lists (and gives you the option to stop) all services currently using port 80.
You can now start your docker container with port 80.
I have a Zookeeper running on port 2181 (default) and a Kafka server listening on port 9090 on my local machine.
When I run kafka CLI locally, or consumer/producer apps locally, I have no problem connecting.
I then try to bundle a Kafka consumer into a Docker container, and run that Docker container locally, e.g.:
docker run -p 9092:9092 --rm <DOCKER_IMAGE>
This gives the error:
(Error starting userland proxy: Bind for 0.0.0.0:9090 failed: port is already allocated.)
This makes sense since Kafka Server is bound to 9092, as shown in nmap -p 9092 localhost:
PORT STATE SERVICE
9092/tcp open XmlIpcRegSvc
I'd have no problem mapping the Docker container to a different port via -p XXX:9090, but how do I get the local Kafka server to listen on that new port without binding to it?
So after some digging I found a few options. (Note: I'm on a mac so #2 may not be applicable to everyone).
Include --network=host in the docker run command (as seen here).
Don't change the docker run command at all, and instead connect to broker at host.docker.internal:9092 inside the container consumer/publisher code. As seen here.
I wasn't able to get #1 to work out for me (I'm sure it's user error). However #2 worked perfectly and just required a config change inside the container.
I have a websocket server running in my host, listening to port 8080.
In a docker container, I deployed a websocket client listening to the said server using this snippet:
connect_url="ws://0.0.0.0:80/"
and, exposing/mapping port 80 of the container to port 8080 of the host.
Dockerfile:
EXPOSE 80
When I ran the container:
docker run -p 8080:80 <name>
But I'm getting this error:
docker: Error response from daemon: driver failed programming external connectivity on endpoint : Error starting userland proxy: Bind for 0.0.0.0:8080 failed: port is already allocated.
Now I think this error is because the server in the host is already using port 8080, that's why it can't be mapped.
With these details given, I just wanted to know how can my websocket client inside the docker container connect to the websocket server in the host.
I think problem is port 80 inside your container already in use, not 8080 on your host machine. Try to use another port for connect socket inside your docker container instead 80 (for example 777 port). Then run docker run -p 8080:777 <name>
By the way, check your host machine port already in user or not:
sudo lsof -i tcp:8080
If not thing show up, that mean port 8080 not yet used. Incase already in use. Kill that process on port 8080:
sudo kill -9 your_PID_ID
Then try again
I tried to run an nginx server on my Mac with:
docker container run --publish 80:80 nginx
It is returning this error.
docker: Error response from daemon: driver failed programming external connectivity on endpoint hungry_shtern (88e68bd0a448ebe25a62c1c897d38a58e7cc581736ea55a0b764197d0416fce6): Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE).
How to fix this?
As other answers pointed, that port is already in use by some other service.
This service is the default apache installed on mac.
To confirm, try:
sudo lsof -i:80
And if you see the command httpd appearing there, the apache server is running, and using port 80.
You could also just try to access http://localhost:80 on your browser. If the apache server is running, you'll see something like "It works!".
To disable this service:
sudo apachectl -k stop
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
After the first command you will be able to bind that port with docker. After the second, you'll disable apachectl on startup.
Maybe port 80 is in use by another process, you need to kill that process or change bind port of docker container:
docker container run --publish 8080:80 nginx
