I was trying to run the docker container on windows 10 but I always get this error "Cannot start service SERVICE_NAME: Ports are not available: unable to list exposed ports: Get "http://unix/forwards/list": context deadline exceeded (Client.Timeout exceeded while awaiting headers)"
. I tried deleting the container and rebuilding it again but that is not working for me.
PS: this error is not related to a specific service, each time happens in a different service although the same service was started successfully before
Any help, please?
This helped me solve the same problem
netsh winsock reset

I installed Docker-ce(ver 17.03.1-ce-mac12 17661) on macOS Sierra(ver 10.12.5)
I created a container and run a simple socket echo server.
And then attempted to connect to the container's echo server from the host.
Initially, when the number of open sockets reached 370, a connection failure occurred,
I found the following via Google search.
https://github.com/docker/for-mac/issues/1009
To summarize, the docker for mac has its own maximum number of connections.
I modified the maximum number of connections moderately according to this content.
And I connected to the docker host in the following way.
http://pnasrat.github.io/2016/04/27/inside-docker-for-os-x-ii
I changed the ulimit configuration of the docker host as well, and changed the osx and container settings accordingly.
And again, I tried again, but this time the number of sockets exceeded the 370 limit mentioned above, but it is also blocked at about 930 ~ 940.
I try to change the settings like this, but it does not get better.
Note that a docker running on top of an Ubuntu server does not need to change any settings, and works well without any socket restrictions.
An echo server running inside the container of a docker running on Ubuntu can maintain at least 4000 sockets.
The problem only occurs with the docker for mac.
If you are aware of this situation, can anyone suggest a solution?
Thank you.
I'd like to get an Elkstack running on my virtual machine. I read up on the topic already a while ago but just recently figured out how to use docker-compose. I found a complete compose file on github (https://github.com/deviantony/docker-elk) which is capable of composing the whole stack, however I ran into two questions: Kibana is awaiting input from Elasticsearch on the url "http://elasticsearch:9200" - The url is obviously not resolving to anything - Hows that supposed to work? I made changes to it so it tries to connect to localhost:9200 but Elasticsearch is refusing the connection - I checked the running containers and saw that elasticsearch is indeed running but using "lsof -i :9200" (or 9300) did not show anything which means it is not listening on the port right? Or would it now show up due to the fact that it is running in docker?
Thanks in advance.
I'm trying to login to docker from the Docker Quickstart Terminal but it doesn't work.
I always get an error saying: "Error response from daemon: Server Error: Post https://index.docker.io/v1/users/: dial tcp: i/o timeout"
I have been working with docker the last few days and was always able to login and push/pull stuff. The only thing different I can think of is that I'm currently on a different Wifi.
Any help is greatly appreciated, thanks.

This is a known issue, and is probably related to VirtualBox; after switching networks, boot2docker/VirtualBox sometimes looses connectivity or uses incorrect DNS settings.
DNS confused when switching WiFi networks
Container connectivity lost after switching wireless networks
Manual restart required everytime network connectivity changes (contains some workarounds)
Docker Machine 0.5.3 adds two new options that may circumvent this;
--virtualbox-dns-proxy
--virtualbox-host-dns-resolver
After restarting the machine it worked again, don't know what caused the problem though...
After successful running the maven project in eclipse, I cannot connect to http://localhost:8082. It shows the below error:
connection refused
What should I do to resolve the problem?
This exception usually occurs when there is no service listening on the port you are trying to connect to. A couple of things could be happening:
You have not started your server.
Your server is not waiting to
accept connections.
You are trying to connect to the wrong port
number.
You should check your services. I think they are either stopped or not working. You can check the services:-
a) if using windows by clicking services in control panel
b) if using linux type in the command Line sudo mqsql service.
you can refer this link- https://www.cyberciti.biz/faq/how-to-find-out-if-mysql-is-running-on-linux/
2)Also check the database connection string might you have not used correct string.
I am trying to deploy a simple rails application to an heroku account, I was able to login and push, only it seems to hang when I try to
heroku run rake db:migrate
or to
heroku run console
I get the message
Running console attached to terminal...
and then nothing happens... it just hangs. I read that it could be I have some blocked ports (like, port 5000) but it seems quite strange to me, I never had such problems before...
I am on Ubuntu, how can I check if that's the case? or how could I fix the issue? Anybody got any hint? I already tried to heroku update, same issue...
Its the port problem i also face the same issue a while ago and their support guys told me top make open the port.
Here is their reply
This problem is typically caused by a connectivity or firewall issue. You can test your connection to our heroku run and heroku console servers by running the following commands:
telnet rendezvous.heroku.com 5000
telnet s1.runtime.heroku.com 5000
Some users have success after whitelisting these hostname+port combinations in their firewall. We recommend contacting your IT department to move forward with this issue.
If you are successfully able to connect, press Ctrl+] (right bracket) and then type quit to exit the telnet session.
An application which takes a long time to boot can also exasperate connectivity issues. If the server does not respond quickly enough, your local connection will timeout before the app can boot.
To test the net enabled access to that port try the following. They mention that filtered-port issue on their guide.
$ telnet rendezvous.heroku.com 5000
