Basic concepts:
Container
Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container is a running virtual machine. A virtual machine image can create multiple running virtual hosts and be independent of each other. Note: Once created, container will persist if not removed with the RM command. So remember to de

solution you choose, make sure it supports multiple master high availability, as well as some election mechanisms to determine which master is the leader or a good end mechanism.3 Not open sourceI was very miserable because I had to put my treasure in a non-open source project. If you don't have a similar experience, you might find it hard to believe. As an example of the Heroku scandal in genius, no one would have imagined that the files of their underlying hosting platform would be falsified,
When you create a Docker container, you should have a new namespace (if you have a separate network), you can see the namespace through the IP netns command, but you can't actually see it.After checking the data, we found that IP netns can only view the network namespace below/var/run/netns. Unlike OpenStack Neutron, Docker automatically creates namespace names in this file and needs to be created manually.

Docker is useless and unnecessary for small and medium-sized enterprises to build Paas. It is a little less useful to use it as a personal sandbox, I personally think that docker can be used as a standard development, testing, and production environment for small and medium-sized enterprises.I drew a simple figure:Docker occupies a small amount of resources. It is more than enough to deploy 100 containers o
