Port Management

When you have multiple containers running service images, port management allows networking between them. Two uses for exposed ports are:

  • Having your containers listen to each other, and
  • Publishing containers to the internet.

You can find port settings in the container’s Settings screen.

Containers need to restart before your changes will take effect.

Restrictions on Port Management

  • Ports below 1024 are reserved for system processes.
  • You are unable to modify ports for containers running web images or applications images. Ports 80 and 443 are open by default to allow HTTP and HTTPS connections.
