Pushing to docker registry running in Kubernetes cluster from Docker Mac

Goal

Push local images from Docker Mac to a remote Docker registry running in a Kubernetes cluster on AWS

Solution

Get ip of your machine (thats the one that docker engine can reach)
$ local_ip=$(ipconfig getifaddr en0)

Define registry.example.com as  in /etc/hosts

  local_ip registry.example.com

Alias lo0 with registration.example.com defined as local_ip in hosts

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOSTThe Mac has a changing IP address (or none if you have no network access). Our current recommendation is to attach an unused IP to the lo0 interface on the Mac; for example: sudo ifconfig lo0 alias 10.200.10.1/24, and make sure that your service is listening on this address or 0.0.0.0 (ie not 127.0.0.1). Then containers can connect to this address.

$ sudo ifconfig lo0 alias registration.example.com/24

Tunnel :5000 to registry DNS 

$ ssh -N -p 22 user@bastion -L local_ip:5000:registry.example.com:5000

Add local_ip:5000 to docker daemon config insecure registries;

save and restart docker daemon

Push to registration.example.com

$ docker tag example-base registration.example.com:5000/example-base
$ docker push registry.example.com:5000/example-base
