Docker Add Insecure Registry How To Do It

Heres how to do it.

You should attempt to protect your registry with SSL certificates but I get it, the real world happens and sometimes youre in a pinch to get something to work.

But before we continue, please understand that anyone can sniff your traffic in between your registry and your box(es) if its not secured by TLS.

Basic idea for setting it up: Youll need to configure both the Docker daemon running your registry and any Docker daemons that plan to interact with that registry by white listing your insecure registry.

On Ubuntu 14.x: Youll need to edit the DOCKEROPTS in your etcdefaultdocker file.

For example, youll want to make it look similar to this: DOCKEROPTS--insecure-registry registry.example.com -H tcp:127.0.0.1:2375 -H unix:varrundocker.sock for a registry running on port 80 on example.com.

Then restart Docker with sudo service docker restart.

On Ubuntu 16.x and CentOS: Youll need to edit or create etcdockerdaemon.json and add this to the file.

On Docker for Windows Mac: Youll want to open the settings, goto the daemon tab and then pop in your registrys URL in the Insecure registries text field.

Now you should be able to pull push to your insecure registry.
