Compared to v1 the following improvements have been made:
- The cost of installing packages have been shifted from each startup to image
preparation phase, thanks to the integration of custom cloud-init profiles
into image-garden. This has dramatic impact on iteration time while also
entirely removing requirement to be online to run once a prepared image is
available.
- Support for running on Google Compute Engine has been removed since it would
not be able to use cloud-init the same way would currently only complicate
setup.
- The number of workers have been tuned for local iteration, aiming for
comfortable work with 16GB of memory on the host. Once CI/CD pipeline
support is introduced I will add a dedicated entry so that resources are
utilized well both locally and when running in CI.
- The set of regression tests listed in tests/regression/apparmor/task.yaml is
now cross-checked so introduction of a new test to the makefile there is
automatically flagged and causes spread to fail with a clear message.
- The task tests/unit/utils has been improved to generate profiles. Thanks to
Christian Boltz for explaining this relationship between tests.
- A number of comments have been improved and cleaned up for readability,
accuracy and sometimes better grammar.
