Unable to access SQS service from docker container

vipul1231 · February 6, 2019, 9:41am

I have a java application deployed on docker container. My service access aws sqs as a requirement but while running service on container I am getting below exception:

nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘queueProcessor’: Invocation of init method failed; nested exception is com.amazonaws.SdkClientException: Unable to execute HTTP request: sqs.ap-south-1.amazonaws.com

Looks like some firewall or iptables configuration is needed inside container in order to access outside resource. Please help

There should be more information in the exception which details the problem such as timeout or some other error. Take a look and post the entire exception here.

Above is complete stack trace. I am not able to do even CURL to external hosted service. ex. curl http://127.0.0.1:8084/health from container.

gforghetti · February 6, 2019, 1:59pm

Are you issuing this command from inside your container?
http://127.0.0.1:8084/health

vipul1231 · February 6, 2019, 2:03pm

Yes. I am firing this command from inside container to check connectivity.

gforghetti · February 6, 2019, 2:09pm

Ah, okay.

Bring up a linux command prompt inside your container and see if port 8084 is open and listening using netstat.

netstat -an | grep :8084

vipul1231 · February 6, 2019, 2:16pm

output of above command:

root@c87dd70e851b:/usr/dockerservice# netstat -an | grep :8084
bash: netstat: command not found

when i try to install basic command (vi, netstat, lsof etc) it’s not updating anything from outside. Seems like container not able connect anything from external world.

Yes, I’m not sure if it’s a firewall issue though.
Can you ping google.com? If not I’m thinking it’s a dns issue in the container or docker.

vipul1231 · February 6, 2019, 2:28pm

You are absolutely correct. No response from ping google.com

root@c87dd70e851b:/usr/dockerservice# ping google.com
ping: unknown host

Okay, try this to see if the problem is just with your container, or all containers.

$ docker container run -it --rm alpine:latest ping www.google.com -c 5

docker container run -it --rm alpine:latest ping www.google.com -c 5

What platform did you install Docker on? (Docker for Linux, Docker for MacOS, Docker for Windows)?

vipul1231 · February 6, 2019, 3:07pm

Installed docker on Ubuntu 18.04.1 LTS

gforghetti · February 6, 2019, 3:20pm

What version of Docker? Run docker version and paste the output here.

Try running a docker container and specifying a dns server and see if this works.

docker container run -it --rm --dns=8.8.8.8 alpine:latest ping www.google.com -c 5

vipul1231 · February 6, 2019, 3:55pm

Same bad address

fcvt18807@FCGRN-L0101:~/Postman$ docker container run -it --rm --dns=59.144.144.100 alpine:latest ping www.google.com -c 5

It appears that you have some sort of “network” issue, proxy issue, etc
I’m at a loss for what else could be wrong.

My setup, I too have Ubuntu 18.04.1 LTS and Docker CE 18.09.1

Thanks Gary. I’ll do some more debugging around this issue. Will post the solution, if it works

vipul1231 · February 8, 2019, 8:22am

It started working using below command.

docker run --net=host -p 8083:8083 javatechy/dockboot
