Hi

I’m trying to use docker.io/ansible/ansible:httptester.
When /services.sh is executed, following errors are prompted:

2018/03/27 13:39:46 [emerg] 43#43: bind() to 0.0.0.0:80 failed (98: Address in use)

2018/03/27 13:39:46 [emerg] 43#43: still could not bind()
nginx: [emerg] still could not bind()

– Already verified that both ports 443 and 80 are NOT occupied by executing following commands:

  • sudo fuser -k 80/tcp
  • sudo fuser -k 443/tcp

Any Idea about this?

When using the container that is on docker hub, there is no need to run services.sh. The “CMD” in the Dockerfile will run services.sh automatically.

The image exposes 80/443, but you also have to instruct docker to publish them. Such as -p 80:80 -p 443:443:

$ docker run --rm -d -p 80:80 -p 443:443 ansible/ansible:httptester

c1b5a01de4eff64832e7082d6441a6a1671aa195710db08f4accd692ffb1eae1

$ curl http://localhost:80/get
{
“args”: {},
“headers”: {
“Accept”: “/”,
“Connection”: “close”,
“Host”: “localhost”,
“User-Agent”: “curl/7.54.0”
},
“origin”: “172.17.0.1”,
“url”: “http://localhost/get”
}

There is a little info about the image and building it at http://docs.ansible.com/ansible/devel/dev_guide/testing_httptester.html

Also: https://github.com/ansible/ansible/tree/devel/test/utils/docker/httptester

I’m not positive what you plan on using it for, but do note that it was purpose built with the intent of using it as a testing endpoint for us.
