None

This PR aims to supersede stale PR #28415 and close #22095, implementing maintainer comments.
If approved I plan to squash down the commits and add myself as co-signer.

Suggested change

	Expect(probe.Exec.Command).To(ContainElement(ctr.healthCmdExpect))
	Expect(probe.Exec.Command).To(Equal([]string{"/bin/sh", "-c", "/bin/true"}))

[Honny1]

The healthCmdExpect should be []string. See my suggestion of assert. (It is not correct.)

[Honny1]

I would use switch something like this:

switch hc.Test[0] {
case define.HealthConfigTestCmd:
    cmd = hc.Test[1:]
case define.HealthConfigTestCmdShell:
    cmd = append([]string{"/bin/sh", "-c"}, hc.Test[1:]...)
default:
    return nil
}
