I need fake a DNS before running a command in my terminal.
Like a export
environment, have a way to do something like this with DNS?

1.2.3.4 kafka
QUESTION
I am using a docker-compose command to create and start my containers.
My Docker Version
docker --version
Docker version 17.09.0-ce, build afdb6d4
My Docker-Compose version
docker-compose --version
docker-compose version 1.16.1, build 6d1ac21
The .yml file that I'm using looks something like this: (Note that I've just shortened it to take sensitive things out)

Answered 2017-Nov-02 at 01:46You won't see custom DNS servers in /etc/resolv.conf
but Docker's resolver will forward DNS requests to them.
Docker compose definitions that are v2+ create a user defined network by default.
Docker with a user defined network uses an embedded DNS server so that Docker can respond for local container requests (service discovery).
For any DNS hosts Docker can not resolve, the request will be forwarded onto a DNS server. This is either the system default server, the server configured in dockerd
or the DNS server configured for the container at run time.
Be careful when using internal DNS servers. Things in the Docker daemon will break if you point the systems DNS at a container as you create a chicken or the egg problem, Docker needs DNS to start but can't start the container to provide DNS.
As your example config is only setting the DNS for one app container it should be ok, but make sure the DNS container is up and healthy before your application.

Install fakeDNS
You can use fakeDNS like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
