Module instance 

Instances: the same environment several times on one host. An instance number (1 to 99) gives a copy its own names and its own room on the host, so two instances of a spec never collide: the name gets a suffix (so Compose project, container, network, VM and namespace names differ), the Docker networks move to other blocks (Docker refuses two networks on one subnet), published host ports shift, and the files go to .isoloom-<n>/ next to the committed .isoloom/. Local VM networks are isolated by name already (VirtualBox internal networks), so machines keep the addresses the spec writes.

Constants

MAX

The highest instance number.

Functions

apply

The spec as instance n of itself (validated specs only).

output_dir

Where an instance’s generated files go.

relocate

A generated file’s path and contents, moved from .isoloom/ to the instance’s folder.
