7.2. Networking #

Networking between the manager and agent can be initiated by either side:

  • The manager can send control instructions to agents, and agents return the execution results in response.

  • Agents can send to the manager requests to register themselves and DBMS instances as well as to update the state of instances. The manager, in turn, sends a response to the agents’ requests.

The manager and agent use the HTTPS protocol for communication. By default, the manager uses the tcp/8080 port, and the agent uses the tcp/8081 port. This traffic direction must be taken into account when configuring network access rules. The address and port are specified in the ppem-manager.yml manager and ppem-agent.yml agent configuration files.

For secure data transfer, TLS configuration is recommended.
