Docker unable to pull images from Docker Hub registry

In AWS, my Docker-based ElasticBeanstalk apps were repeatedly removing & adding instances. This resulted in many “Adding instance ‘i-465f6382’ to your environment.” type messages. In the docker-events.log the message “Could not reach any registry endpoint” was repeated. I got the same message when running a “sudo docker pull ubuntu” manually on the EC2, even though network connectivity seemed ok.

As it turns out, Docker Hub has deprecated pulls from Docker clients on 1.5 and earlier. See for more information.

Also, due to a bug in the ElasticBeanstalk console UI, I had to use the EB CLI command “eb config” to trigger an update of the platform.
