Interesting, how has it worked in the past?

Probably, it was failing in the past too. I realized that even if with those commands were failing, the execution of the script continued.
I see that at the beginning of the file is defined

$ErrorActionPreference = "Stop"

but it does not stopped the execution. Not sure if choco command does not return any error in that scenario, or when the error is inside a function there are some differences in how to manage the errors.

WDYT about changing these defaults values to use the wolfi image docker.elastic.co/elastic-agent/elastic-agent-wolfi (e.g. no version specified) instead of the legacy image (beats namespace) docker.elastic.co/beats/elastic-agent?

Or should we keep unchanged this default?

We can adapt this to the new default, yes, if we are sure that in old versions the beats namespace is used.

Yes, the same behaviour is kept.
As a reference, I add here the docker images used in different versions:

As it is now, the Elastic Agent image is chosen as:

  • If stack >= 8.16.0-SNAPSHOT,
    • by default it is used wolfi image_ docker.elastic.co/elastic-agent/elastic-agent-wolfi.
    • if ELASTIC_PACKAGE_DISABLE_ELASTIC_AGENT_WOLFI=true, then it is selected the Elastic Agent image as before. So if stack >= 7.15.0-SNAPSHOT, it will be used the complete image.
  • If the configuration file of the system test has base_image: complete:
    • It will be used the complete version of the Elastic Agent image if the stack version allows it.
  • If the configuration file of the system test has base_image: systemd:
    • It will be used the systemd version of the Elastic Agent image. That means docker.elastic.co/elastic-agent/elastic-agent or docker.elastic.co/beats/elastic-agent depending on the stack version.

Would that be ok? Specially if stack version is set to 9.0.0 and the environment variable to disable wolfi is set to true.

If the same set of images is going to be available in 9.0 keeping the same logic sounds good to me.

This is the test changing the value, it would return the wolfi image instead.

In principle it LGTM. Maybe another option is to return an error if the version is empty? Not sure about the implications of the change, but would look safer to me to know where/if we are passing an empty version.

Commands like elastic-package stack down do not set any version, and if a error is returned here, it will fail the command.
