Alpine Linux does not support the lsb_release command. The lsb_release command is used by the platformlabeler-plugin to determine the name of the Linux distributor. For example, it is used to determine CentOS, Debian, SUSE, and Ubuntu as Linux operating system distributions.

The platformlabeler plugin should support Alpine Linux since it is the basis of one of the three Jenkins Docker images and is increasingly the preferred image due to its small size.
