register-dynamic-backend

Creates a new dynamic backend.

The arguments are the name of the new backend to use, along with a string describing the backend host. The latter can be of the form:

• "<ip address>"
• "<hostname>"
• "<ip address>:<port>"
• "<hostname>:<port>"

The name can be whatever you would like, as long as it does not match the name of any of the static service backends nor match any other dynamic backends built during this service instance. (Names can overlap between different instances of the same service—they will be treated as completely separate entities and will not be pooled—but you cannot, for example, declare a dynamic backend named “dynamic-backend” twice in the same sandbox.)

Dynamic backends must be enabled for the Compute service. You can determine whether or not dynamic backends have been allowed for the current service by checking for the error.unsupported error result. This error only arises when attempting to use dynamic backends with a service that has not had dynamic backends enabled, or dynamic backends have been administratively prohibited for the node in response to an ongoing incident.
