Consul

Consul is a distributed service mesh to connect, secure, and configure services across any runtime platform and public or private cloud.

Consul Configuration for dashboard

CAP's Dashboard uses Consul as a service discovery to get the data of other nodes, and you can switch to the Servers page to see other nodes.

Click the Switch button to switch to the target node, CAP will use a proxy to get the data of the node you switched to.

The following is a configuration example, you need to configure them on each node.

services.AddCap(x =>
{
    x.UseMySql(Configuration.GetValue<string>("ConnectionString"));
    x.UseRabbitMQ("localhost");
    x.UseDashboard();
    x.UseDiscovery(_ =>
    {
        _.DiscoveryServerHostName = "localhost";
        _.DiscoveryServerPort = 8500;
        _.CurrentNodeHostName = Configuration.GetValue<string>("ASPNETCORE_HOSTNAME");
        _.CurrentNodePort = Configuration.GetValue<int>("ASPNETCORE_PORT");
        _.NodeId = Configuration.GetValue<string>("NodeId");
        _.NodeName = Configuration.GetValue<string>("NodeName");
    });
});
