When updating images, increment the version for the image in the `tags` config.
You will also want to update the sample YAMLs

## Building official images

Set `HUB=docker.io/istio` for official image builds.

== Publish a Build Scan

The best way to learn more about what your build is doing behind the scenes, is to publish a link:https://scans.gradle.com[build scan].
To do so, just run Gradle with the `--scan` flag.

[listing.terminal.sample-command]
----
\$ ./gradlew build --scan
