Amazon Corretto

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of OpenJDK. It includes long-term support with performance enhancements and security fixes from Amazon.

What's included

• java — JVM runtime
• javac — Java compiler
• jar — archive tool
• jshell — interactive REPL (JDK 11+)

Available versions

• Corretto 27 — JDK 27 (not yet released upstream)
• Corretto 26 — JDK 26 (newest — feature release, not LTS)
• Corretto 25 — JDK 25 LTS
• Corretto 21 — JDK 21 LTS
• Corretto 17 — JDK 17 LTS
• Corretto 11 — JDK 11 LTS
• Corretto 8 — JDK 8 LTS

Version scheme

Corretto tags are mapped to OCX versions as major.minor.update_build, where build = jdkBuild × 1000 + correttoRevision.

JDK 8 tags have no minor version — minor=0 is inserted during conversion.

Use amazon/corretto:21 for the latest JDK 21 release, or amazon/corretto:latest for the newest release of the highest JDK major.

:latest follows the highest major, which is 26 — a six-month feature release, not LTS. Pin an LTS line (:25, :21, :17, :11, :8) if you need one.

Platforms

Linux, macOS and Windows on x86-64, plus arm64 everywhere upstream ships it. Both Linux libc flavours are carried: the glibc build (+libc.glibc) and Amazon's separate Alpine build (+libc.musl). Neither is static, so the right one is selected for the host automatically.
