          isValidContainerVersion.containerVersion
        } is a valid Container version`
      )
      Ensure.isValidContainerVersion(
        isValidContainerVersion.containerVersion,
        isValidContainerVersion.extraErrorMessage
      )
      kaxTask.succeed()
    }
    if (isNewerContainerVersion) {
      kaxTask = kax.task(
        'Ensuring that container version is newer compared to the current one'
      )
      await Ensure.isNewerContainerVersion(
        isNewerContainerVersion.descriptor,
        isNewerContainerVersion.containerVersion,
        isNewerContainerVersion.extraErrorMessage
      )
      kaxTask.succeed()
