Thanks to the network speed and the performance of the Greater China LAN, the image download speed in DockerHub is very slow. Even some domestic image warehouses do not feel very fast. Therefore, it is necessary to build an image repository locally or in a place that we can access quickly (your own ECS. With such a repository, we can
Preface

Application background:Docker is the first to run on Ubuntu and Debian, using AUFS memory. Because Docker is becoming more popular, many companies want to use it on Rhel, but the upstream kernel does not include AUFS, so Rhel cannot use Aufs.Eventually, developers developed a new back-end storage engine Devicemapper, based on existing device mapper technology, and made Docker support pluggable, and now ther
