About Docker DNS and Networking

Today I learned about networking and DNS with Docker containers:

• Docker Networking and DNS: The Good, The Bad, And The Ugly
• Fix Docker’s networking DNS config
• Docker containers can’t resolve DNS on Ubuntu 14.04 Desktop Host

I’ve hard-coded the DNS servers into: /etc/docker/daemon.js:

{
  "dns": ["1.0.0.1", "1.1.1.1"]
}

Now, restart Docker daemon. Then you should be able to connect to the internet from within your Docker container.
