Consul+docker Service registration and service discovery
Using consul to implement service registration and service discovery is a simple matter. Many features are available out of the box.
Preparatory work
I have the opportunity to build a Docker micro-service architecture in my current job, a lot of people will share their experience of using Docker, I think I will be no exception. So I've summed up some of the things that you might use in your daily use of Docker.
1. Deployment of multiple Docker instances on a single host
If you want to run multiple Docker containers on a single host, this is especially useful if you want to set different TLS settings, network settings, log settings, and stor

Strings: A string of characters enclosed in "".
Value: A series of 0-9 numeric combinations that can be negative or fractional. It can also be expressed in exponential form by E or E.
Boolean value: expressed as true or false.
The format description for JSON can be referenced in RFC 4627.
Here is an example of a JSON configuration file:

2.0.0.build-snapshot
Configuration management tools that support the use of Git, SVN, and other storage profiles. And in support of client configuration information refresh, encryption and decryption configuration content.

Core components to consolidate multiple Netflixoss open source suites.

To support container Cross host communication, Docker provides overlay driver, allowing users to create overlay networks based on Vxlan. Vxlan can encapsulate two-tier data into UDP for transmission, Vxlan provides the same Ethernet two-tier service as the VLAN, but with greater scalability and flexibility. More detailed information about Vxlan can be referenced in the relevant chapters of Cloudman's 5-minute play OpenStack every day.
