Error occurred when deploying the Platform in a cluster

Problem: not all services are started up when executing a command ./setup/deploy.sh.

Solution: Request the log platform-postgres-dep using the command:

 kubectl logs -f <full name of pod>

If the output shows an error about incorrect database name or authorization data, check the correctness of the entered authorization data in the ./cfg/platform.secrets.json file.

Problems with connection to BAF server

The connection to BAF Server can be refused due to firewall operation in your OS.

Solution: If a firewall is used with the default settings, simply open all firewall ports. In case the settings are customizable, you'll need to open ports 8080, 80, 443, 8090.
