Add hosts

How to add virtual machines and containers to sandboxes.

Overview

Sandboxes support VMs and containers natively. Use the following points to determine if you should use one or the other.

You should use VMs if...

• You need control how many CPUs the host gets

• The host needs to be externally accessible (see networking documentation)

You should use containers if...

• You want to make loading times as short as possible (they are generally faster to deploy)

• You have a lightweight application with minimal resource requirements
