Configure satellite communication

This topic covers how to configure communication between Deploy satellites and the Deploy master to ensure secure and effective operations.

Enable communication with satellites​

In Deploy, communication with satellites is disabled by default. To enable it:

  1. Locate the satellite section in the deploy-satellite.yaml file.
  2. Set enabled to yes:

deploy.satellite: enabled: true

1. Restart Deploy. The server will be enabled to connect to satellites.

## Configure hostname and port

The default settings in the `deploy-server.yaml ` file are:

hostname: "" bind-hostname: "0.0.0.0" port: 8180

Set `hostname` to an IP address or a host name where Deploy can connect. Deploy send this value to the satellites. The hostname must be visible from the network(s) where the satellites are located.

Satellites use this value to re-establish connection with Deploy if the initial connection breaks. If you do not provide a value, Deploy assign a value from a network interface that is available, or to a loopback address if no interfaces are available.

Set `bind-hostname` to an IP address or a host name to listen on. The default setting listens on all network interfaces.

Set `port` to the port that Deploy connects to. The port must also be accessible from the satellites. The default port is set to `8180`.

**Note:** You cannot connect multiple Deploy server instances to the same satellite. In Deploy, you can assign the same satellite to multiple hosts from the same Deploy instance.

## Configure the ping timeout

To configure the ping timeout while reaching a satellite, change the `satellite.timeout.ping` property in the `deploy-satellite.yaml` file:

```js
satellite {
   timeout {
     ping = "<timeout>"
   }
 }
hostname: ""
  bind-hostname: "0.0.0.0"
  port: 8180

You can specify the ping timeout in milliseconds, seconds, or minutes. For example: 100 ms or 10 seconds.

Configure the upload idle timeout​

The upload idle timeout occurs when a satellite has accepted an incoming streaming connection but does not need to accept the uploaded file. This prevents unused TCP connections from remaining open. To configure the upload idle timeout, change the satellite.timeout.upload.idle property in the deploy-satellite.yaml file:

deploy.satellite:
  timeout:
    upload:
      idle: "<timeout>"

You can specify the ping timeout in milliseconds, seconds, or minutes. For example, 100 ms or 10 seconds.

Configure the file streaming timeout​

This timeout occurs when Deploy attempts to connect to satellites for file transfer. To configure this value, change the satellite.timeout.streaming property in the deploy-satellite.yaml file:

deploy.satellite:
  timeout:
    streaming: "<timeout>"

The default timeout is 10 seconds.

Configure the maximum upload threads per task​

To configure the maximum threads per upload task, change the satellite.streaming.max-uploads property in the deploy-satellite.yaml file:

deploy.satellite:
  streaming:
    max-uploads: 5

Configure secure communication​

Deploy communicates with satellite servers over a secure communication channel using TLS/SSL technology to encrypt data. For more information about configuring SSL, see Configure secure communication between Deploy and satellites.
