Jenkins Azure VM Agents now supports Shared Images
Background For a long time sharing custom OS images between Azure subscriptions has been a painful, time consuming process. Thankfully Microsoft have addressed that with the introduction of Shared Image Gallery (SIG). However, the SIG is only as useful as the tools that can consume it and with SIG still in preview, some tools are not yet able to leverage it.
Thankfully though, the Microsoft team that manages the Jenkins Azure VM Agents plugin have been quick to update the plugin to support the SIG.
