Amazon Corretto 8がGAになったので、 Cloud FoundryのJava Buildpackで使ってみます。
2019-08-13 1.8.0_222, 11.0.4_11を追加
2019-02-16 Amazon Corretto 11に対応しました。
Java Buildpackで用意されているOpenJDKではなく、任意のJDKを使う場合は、次のようなindex.ymlを作成してHTTPサーバーでホストして、URLを指定すれば良いです。
1.8.0_202: "https://d2znqt9b1bc64u.cloudfront.net/amazon-corretto-8.202.08.2-linux-x64.tar.gz"
1.8.0_222: "https://d3pxv6yz143wms.cloudfront.net/8.222.10.1/amazon-corretto-8.222.10.1-linux-x64.tar.gz"
11.0.2_09: "https://d3pxv6yz143wms.cloudfront.net/11.0.2.9.3/amazon-corretto-11.0.2.9.3-linux-x64.tar.gz"
11.0.4_11: "https://d3pxv6yz143wms.cloudfront.net/11.0.4.11.1/amazon-corretto-11.0.4.11.1-linux-x64.tar.gz"
https://raw.githubusercontent.com/making/amazon-corretto-buildpack/master/index.ymlに置いておきました。
ちなみにデフォルトで利用可能なJDK一覧はhttps://java-buildpack.cloudfoundry.org/openjdk/trusty/x86_64/index.ymlです。
このJDKリストを指定するにはmanifest.ymlに設定します。
applications:
- name: demo-correto
path: target/demo-corretto-0.0.1-SNAPSHOT.jar
buildpacks:
- https://github.com/cloudfoundry/java-buildpack.git#v4.17.2
env:
JBP_CONFIG_OPEN_JDK_JRE: '{ jre: { repository_root: "https://raw.githubusercontent.com/making/amazon-corretto-buildpack/master" } }'
これでcf pushすれば、Staging中に次のようなログが出力されます。amazon-correttoがダウンロードされていることがわかります。

System Propertiesをみるとjava.vm.vendorがAmazon.com Inc.になっているのがわかります。
Correto 11を使いたい場合はversionを指定します。Java Buildpack 4.17時点ではデフォルトは8です。
applications:
- name: demo-correto
path: target/demo-corretto-0.0.1-SNAPSHOT.jar
buildpacks:
- https://github.com/cloudfoundry/java-buildpack.git#v4.17.2
env:
JBP_CONFIG_OPEN_JDK_JRE: '{ jre: { version: 11.+, repository_root: "https://raw.githubusercontent.com/making/amazon-corretto-buildpack/master" } }'
こちらでcf pushするとCorreto 11がダウンロードされます。

Buildpackを使っている限り、Cloud Foundry BuildのOpenJDKを使うので良いと思いますが、 開発もCFもCorrettoで統一したいというレアな要望があればどうぞ。
