"driver failed programming external connectivity on endpoint" (1.7.0-rc1)

[jamshid]

I'm pretty sure this was working on docker-compose 1.7.0-rc1 before I installed the latest Docker for Mac beta, which upgraded to docker 1.11.0-rc3. I'm trying to get the socat service to run on port 172.17.0.1:8123, so that it's available to docker builds. My real yml uses an environment variable for the IP address, but it happens even when hardcoded.

ERROR: for socat_httpcache  driver failed programming external connectivity on endpoint test_socat_httpcache_1 (5d973ed559d63a5561b715248f797a336915a44960b5e32e622ac8349b16e5d2): Error starting userland proxy: failed to bind port: Unix.Unix_error(Unix.EADDRNOTAVAIL, "bind", "")

@jamshid
Can you post the o/p of sudo netstat -nlp | grep 8123. Thanks.

[jamshid]

My mac says -p requires an argument, so I think this is what you want:

$ sudo netstat -nl -p tcp  | grep 8123
(nothing)
$ sudo netstat -nl -p tcp  | head    # to confirm mac output is what you expect

[bezelga]

same thing happening to me.

[leeahoward]

I am getting the same issue when restarting using docker-compose up. In my case it's an nginx proxy service that fails to start. Must be related to the Docker for Mac beta. It started after I installed the beta and hasn't happened after switching back over to Virtualbox.

docker-compose version 1.7.0, build 0d7bf73
Docker version 1.11.0, build 4dc5990

[elghazal-a]

I encouner the same error when I try to start my stack using docker-compose. All the containers start correctly except one (consul). I'm getting this error

ERROR: for consul driver failed programming external connectivity on endpoint devas_consul_1 (6ceba32c51cb70b354f 2f4b68d173ca97a65d6a0bfd308d3137e2a7069abd1b6): Error starting userland proxy: Failed to bind: EADDRNOTAVAIL

I'm sure it has something to do with my docker version beta for mac.

docker-compose -v docker-compose version 1.7.0, build 0d7bf73

I'm using the last docker beta version for mac

Following the above message, I get Error starting userland proxy: Failed to bind: EADDRINUSE.
Confused as to where the conflict is where none existed before

[mattgi]

How does one "release" the port that is in use so that compose can bring up the container again? First time it happened, I waited for a minute or so and it worked on second attempt. Second time, its been about an hour. Docker compose kill, down, rm --all, etc. and something still has a hold of it.

[mattgi]

FYI, tracked in the beta @ https://forums.docker.com/t/port-mappings-are-not-released/10565/11

[elghazal-a]

I figure out what the problem is about, the container (consul) causing the issue has this binding port 172.17.0.1:53:8600/udp. I replaced it with 53:8600/udp and it's working now. I didn't understand yet why the first binding doesn't work. BTW, How can I know the bridge ip address?

I'm seeing this sporadically. Retrying the command after a minute usually "fixes" the problem.

[kausik93]

I've also been getting the same error as you guys. I believed it was because nginx was binding it ports that were already taken up but I don't think so now. Did anyone find any solutions to this? :)

[briankelleher]

+1 Same error on mac

[joemewes]

I had this happening after a move to Docker for Mac, but after stopping and removing All containers after the move, restarting docker, recreating container etc etc. It was fixed.

I had this again today after an update of Docker for Mac , but repeating the above scenario fixed. I assume the port (and "other" things) I'm assigning to particular containers is not being released until completely cleaned up.

eg:

ERROR: for nginx driver failed programming external connectivity on endpoint dev_nginx (4c340c55f7402c7b265803ea64541ebdf8613f4b43dfa816001d27bdc4f513b3): Error iptables FORWARD: Another app is currently holding the xtables lock; waiting (1s) for it to exit...

[miraage]

Found solution for people with same error as I shown above.
I was previously using Docker Toolbox, but I did not delete Virtualbox. It was using my ports so I can not start. After complete removing VirtualBox, docker-compose worked awesome.

@aanand @dnephin please, add to Getting Started a warning like explained above.

[FrenchBen]

@miraage happy to hear you solved your issue.
I didn't have your volume data+dump.sh but did a quick compose without issues:

Creating driverfailed_cache_1
Creating driverfailed_db_1
Attaching to driverfailed_cache_1, driverfailed_db_1

@jamshid Why are you specifying an IP for socat (not familiar with it)? How are you using it?
Doing a docker-compose up without the IP I don't have any issues:

Creating socat_httpcache_1
Creating socat_socat_httpcache_1
Attaching to socat_httpcache_1, socat_socat_httpcache_1

docker ps

If your goal is for your http_cache to talk to the socat container, why not put them on the same network and be done with it?

Well, I'm using docker engine 1.11.2 in centos7 in a Continuous Build/Integration flow to automate tests and as far as I can tell, eventually this error pops up even though no container is running (while re-deploying a specific version of the whole service stack). Also it seems related to the fact that sometimes docker engine gets an error on trying to cleanup after the removal of running containers, and some iptables rules might be kept allocating network ports for some reason, maybe related to moby/moby#23371 (comment) - but I'm still not sure about that.

[igorrKurr]

I've had pretty same issue, with Docker for Mac, running postgresql container. So, for me it was caused by postgres running on same port on host system as port specified in my compose config file. Pretty obvious thing, but could be helpful for someone I guess.
Thanks for cool tool. 👍

[marcosalberto]

I had a similar problem Docker for Mac running nginx container, my port 80 was being used by apache (native). I used telnet and netstat to see the running service.

[surajadh]

For me it was squid, I stopped squid and didn't see that anymore. So I think it may have to do with whatever is taking up the port and if we force docker to map that port.

[FanYikang]

I've encountered same behavior.
This solved my issue on centos7:
ps -ef | grep docker
kill the "...dockerd -H fd:// --containerd=/run/containerd/containerd.sock" process

[JackOfSpade]

Found this thread, and none of the above helped me.

I am running Ubuntu and I had to use:

sudo service docker restart

I tried prune and all the other commands and docker was sure it had nothing running, but after restarting the service, it all started working again.

THANK YOU! HOLY FK, I SPENT A WHOLE DAY TRYING TO FIX THIS.
THE YEAR IS 2020, THAT'S 4 YEARS AND THIS PROBLEM STILL EXISTS. WTF

[Slisarenko]

/etc/init.d/redis-server stop
I'm using docker, in my case, It helped me

[vakenbolt]

Just had encountered the same issue complaining about a Postgres container. Curiously, exiting Docker for Mac (desktop) did not solve the trick, I had to actually select Restart from the menu and that fixed the issue.

[nagy135]

just read through this thread, and what seems to be the best answer in 2021 is to restart docker service (sv restart docker, systemctl restart docker, etc ....)
That indeed makes it work again, but why this is happening is unclear still from this thread

[krisnova]

run;

systemctl restart docker

---

happened to be kernel networking debugging at the same time - a previous container instance was the culprit

iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8081 -j DNAT --to-destination 172.17.0.2:2342 ! -i docker0: iptables: No chain/target/match by that name.

was what gave it away when iptables couldn't DNAT on the docker0 interface

[lucatsf]

I got it by doing the command
sudo systemctl stop httpd or sudo /etc/init.d/apache2 stop

[mortensassi]

I got it by doing the command
sudo systemctl stop httpd or sudo /etc/init.d/apache2 stop

same here. Reinstalled PHP on my Ubuntu 20.04 and had a simple test running. Seems like apache runs per default on port 80:

# $ sudo netstat -nlp | grep 80
tcp6       0      0 :::80                   :::*                    LISTEN      848/apache2         

[Daniel-M]

I'm experiencing the same problem with:

Docker version 20.10.5, build 55c4c88
docker-compose version 1.29.0, build 07737305

I'm unable to restart my services since docker-compose says they are already running, which is true because docker-compose brings those containers up and fails telling they are already up. Restarting the service systemctl restart docker.service and systemctl restart docker.socket does nothing unless I restart --yes, restart-- the OS

[mortensassi]

@Daniel-M you could try and find the docker process ps aux | grep docker and kill -9 <THE PID> - did you make sure no other process is occupying that port?

[Daniel-M]

@Daniel-M you could try and find the docker process ps aux | grep docker and kill -9 <THE PID> - did you make sure no other process is occupying that port?

I made 100% sure nothing else was using those ports. The odd thing was the following sequence

• docker ps -a shows no containers
• docker-compose up fails starting a couple of containers since the ports are allegedly in use
• docker ps -a now shows the failed containers running, the ones docker-compose reported as failed to start
• Only those containers are running, so the project is useless

As for killing docker I did not tried that, I relied on systemctl, but will try that next time

After I restarted my computer today to continue working, docker-compose did not failed (as expected) but I'm not willing to try, have to keep working on things, I wouldn't be surprise it this happen gain, I will provide screnshots or even a video of the console

Thank you for your suggestion @mortensassi

Stop and start the service completely. That’s fixed it for me.

I had the same problem today on my Ubuntu 20.04. This error just appeared. I think it was because of a recent update.

Additional information:

WARNING: Host is already in use by another container

important note: HOST is already in use.

Checking with ps and netstat the corresponding ports are free but on my system I have ipv6 disabled. Looks like Docker is trying to use ipv6 for whatever reason from now on??

Error starting userland proxy: listen tcp6 [::]:6379: socket: address family not supported by protocol

[wsw70]

@dmtanner thank you very much for your comment.

After upgrading packages on my system and rebooting I was stuck with docker trying to connect to IPv6 despite being disabled on my system.

Downgrading helped, the command is (in case someone is desperate and in a hurry)

apt install docker-ce=5:19.03.15~3-0~ubuntu-bionic
systemctl stop docker
systemctl start docker

---

EDIT: I did not realize that the issue was opened in 2016...

In my case the problem is definitely with IPv6: up to and including version 19 the fact that it is disabled on my system was handled correctly, I upgraded today to 20.something and random issues with containers not starting because of that happened.
Downgrading fixed everything (there were no changes in the configuration of the containers).
I did not have messages about the "HOST being already used ...", just

MacOS user here. This problem usually happens randomly to me. No processes on the troubled port. Not even a single container, no vbox virtual machine up, nothing.

Restarting didn't fix anything. Updating and restarting the Docker service using the Docker Desktop app fixed the issue. Not sure if this will fix the issue in the future.

Ubuntu 20.04 here, the error message was

Error response from daemon: driver failed programming external connectivity on endpoint nginx (b05d13ec7f7c76e6cb4e1bbec142a5655d875477c081e71371179cda80efadb0): Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use
Error: failed to start containers: nginx

To resolve this issue, I used sudo netstat -plant | grep 80 and found that apache is using the port, and then I just typed sudo systemctl stop apache2.service.

Hope it helps.

The same error is thrown when the port is occupied, but for users experiencing this issue who have confirmed the port is unoccupied it is more complicated.

The underlying issue is due to a breaking change introduced in Docker version 20.10.6 that breaks networking for devices that don't have ipv6 enabled.

The only solution is rolling back to 20.10.5 until a fix is published.

For additional info see here docker/for-linux#1233

Unfortunately running into the same issue today, running a Postgres container. Port in use error but the port isn't used, ran all the diagnostic commands I could find to verify this. Restarting the Mac didn't change anything. No way to rollback to the previous version, however, killing docker and restarting it with the following command seems to have fixed the issue:

killall Docker && open /Applications/Docker.app

[snogrammer]

@CodingNagger same for me. I just updated to 3.4.0 and seems to be working for the time being, but keeping your command ready since force killing it seems to be the only way to get my containers to run.

Ran into this issue today. Tried many of the commands above, nothing worked.
Looking into netstat showed no process running on the same port. Launching the container on another port led to the same error.
Rebooting fixed the issue.

[kokizzu]

ran this issue today
same port (9000) used by another program/docker
stopping all other docker on docker ps and the service (probably systemctl stop clickhouse-server) works

[PRodO5lNk5]

I had the same issue which was caused by my local php8 instance (local apache2 server took over the address)
sudo systemctl stop apache2.service Solved it.

As your error states: something is already running on port 4200.

[davidcsi]

Restart Docker completely.

@buckbeak99 If you already restarted the docker service, and this is still popping up, then yes, something else (other than your docker containers) is taking that port number.

Sometimes docker ends up in a weird state where the containers are down but the networks are up and you cannot raise your containers because the ports are taken. Restarting the docker service should clear this issue.

Thank you, @morales2k, and @davidcsi. After restarting my laptop, the error is solved completely. Thanks again for your precious advice.
