<# NOTE!!!! Classes are loaded into a PS Session one time and any change you make are not reflected in the session until you restart the session. This also means if you make a change to a **function** that uses a class, then reload the psm1, you may be fun errors like "Cannot convert the "PodStatus" value of type "PodStatus" to type "PodStatus"." since the psm1 has a new version of the class and the session has the old version. Even updating this comment will break it. When in doubt, restart the session. #> enum Status { Unknown Running Timeout Crash ConfigError Completed } enum RollbackStatus { Unknown DeployedOk NoChange HelmStatusFailed Skipped RolledBack } # state.running means running, has startedAt # state.terminated means crash, has optional reason, etc. only exitCode req'd # state.waiting means bad image, missing secret, has optional reason function mapContainerStatus($containerStatus) { if ($containerStatus.ready) { return [Status]::Running } if ((Get-Member -InputObject $containerStatus.state -Name 'waiting') -and $containerStatus.state.waiting) { return $containerStatus.state.waiting.reason -eq "CrashLoopBackOff" ?
