Creating container fails with invalid IP address for add-host

[goloroden]

I have written a software that controls Docker by using its REST API.

For months, it worked perfectly. Now I am having issues, since I updated from Docker for Mac 17.03 to Docker for Mac 17.06. If I create a virtual machine with Docker 17.03 using docker-machine, everything works as expected. So apparently between 17.03 and 17.06 something has changed.

The error message that I get is:

Failed to create container chat-broker. Error response from daemon: invalid IP address in add-host: ""

What's strange about this, is that I nowhere try to set the add-host option for the chat-broker container.

Do you have any idea of what might cause this issue, and how I could get around this?

PS: The same behavior happens in 17.05 on Ubuntu. So there must have been a change in the API which causes this behavior between 17.03 and 17.05. Any ideas?

Okay, we found it. This was an issue with our code, not Docker's API. Sorry for the trouble.

what was the issue in code ? I am getting the same error

@asbaghel08 I'm really sorry, but I can't remember … it's almost five years ago (and yes, it would have been nice if I had mentioned the solution back then).
