Where should i store the endpoint of the service registry server?

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?

Solution

  • 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
