我应该在哪里存储服务注册服务器的端点？

Question

I'm learning about microservices recently. I tried using consul for service discovery. I wonder if I deploy the consul server, so where should i store endpoint of that server? Is it good to hard code in env variable of each services?

Answer 1

All of the 3 following options are supported in the following precedence order:

1. Command line arguments
2. Environment Variables
3. Configuration files

For the Linux Configuration File Option

Create

/etc/consul.d/config.json

The key is start_join with value of the IP of Consul server e.g.,

"start_join": [ "10.128.0.2" ]

For a cluster solution of more than one Consul instances:

"start_join": [ "10.128.0.2", "10.128.0.3" ]

The default server port is 8300 but you may override with the ports object offering multiple ports to override e.g.,

"ports": {
   "server": 8300
}

For a full reference of the available options, you may check the Consul Documentation, and all the available ports options
