@@ -8,9 +8,15 @@ initrd images for all supported distributions and then tests them to ensure a
Kata Container can be created with each.
Before the build phase, the test script installs the Docker container manager
and all the Kata components required to run test containers. This step can be
skipped by setting the environment variable `KATA_DEV_MODE` to a non-empty
value.
and all the Kata components required to run test containers. Individual tests
will also alter host `kata-runtime` and `docker` service configuration as needed.
All host config editing can be skipped by setting the environment variable
`KATA_DEV_MODE` to a non-empty value. In this mode, image/initrd targets
will be built but not runtime tested; If your host is configured to have
`kata-runtime` set as the default docker runtime, you will need to switch
to a runtime like `runc`/`crun` so the `docker build` test commands work
correctly.
