See also: How to use a blueprint
In Multipass, a blueprint is a recipe to create a customised Multipass instance.
Blueprints consist of a base image, cloud-init initialisation, and a set of parameters describing the instance itself, e.g. minimum memory, CPUs or disk.
Blueprints are defined from a YAML file with the following schema:
# v1/<name>.yaml
description: <string> # * a short description of the blueprint ("tagline")
version: <string> # * a version string
runs-on: # a list of architectures this blueprint can run on
- arm64 # see https://doc.qt.io/qt-5/qsysinfo.html#currentCpuArchitecture
- x86_64 # for a list of valid values
instances:
<name>: # * equal to the blueprint name
image: <base image> # a valid image alias, see `multipass find` for available values
limits:
min-cpu: <int> # the minimum number of CPUs this blueprint can work with
min-mem: <string> # the minimum amount of memory (can use G/K/M/B suffixes)
min-disk: <string> # and the minimum disk size (as above)
timeout: <int> # maximum time for the instance to launch, and separately for cloud-init to complete
cloud-init:
vendor-data: | # cloud-init vendor data
<string>
health-check: | # a health-check shell script ran by integration tests
<string>
Blueprints currently integrated into Multipass can be found with the multipass find command.
