When performing a customer upgrade we had the following issues:
- By not specifying a java_version, they risked installing different versions between their testing and production environments.
- When specifying a java_version, they had trouble telling which versions were available in the Apt repository, which will make it difficult for them when they next want to bump the Java version.
I've sent a few emails to Azul support asking for advice on the second point. As far as I can tell, the usual apt tools (e.g. apt policy) don't list which OpenJDK versions are available in the Azul Apt repository. The version strings used in the repository don't seem to be listed anywhere on Azul's page. How did we guess the string "13.33.25-2"?
Azul's support guy recommended we instead script installs around their REST API. I will include parts of his email here:
Use the Azul OpenJDK Discovery API ( https://www.azul.com/downloads/zulu-community/api/ )
As example, to get the list of Zulu DEB builds for Ubuntu, you can use this command:
$ curl -H "Accept: application/json" "https://api.azul.com/zulu/download/community/v1.0/bundles/?jdk_version=13&ext=deb&os=linux&arch=x86&hw_bitness=64"

As examples, I successfully downloaded these two builds by running the following commands:
a) $ curl -L -o zulu13.31.11-ca-jdk13.0.3-linux_amd64.deb "https://api.azul.com/zulu/download/community/v1.0/bundles/11259/binary/"

I think we should consider fetching installers via the URLs given by this API instead of fetching from their Apt repo.
I think there would be these benefits:
