About
Mandrel focuses on GraalVM's native-image component in order to provide an easy way for Quarkus users to generate native images for their applications.
Developers using Quarkus should be able to go all the way from Java source code to lean, native, platform-dependent applications running on Linux.
This capability is vital for deploying to containers in a cloud-native application development model.
Before you start
Gradle configuration
Before you start it is assumed that you installed SDKMAN, Java and Gradle.
sdk install java 17.0.4.1-tem
sdk install gradle 7.5

10. Excerpt from official Mandrel documentation
Mandrel 22.2.0.0-Final is a downstream distribution of the GraalVM community edition 22.2.0.
Mandrel's main goal is to provide a native-image release specifically to support Quarkus.
The aim is to align the native-image capabilities from GraalVM with OpenJDK and Red Hat Enterprise Linux libraries to improve maintainability for native Quarkus applications.
How Does Mandrel Differ From Graal
Mandrel releases are built from a code base derived from the upstream GraalVM code base, with only minor changes but some significant exclusions.
They support the same native image capability as GraalVM with no significant changes to functionality.
They do not include support for Polyglot programming via the Truffle interpreter and compiler framework.
In consequence, it is not possible to extend Mandrel by downloading languages from the Truffle language catalogue.
Mandrel is also built slightly differently to GraalVM, using the standard OpenJDK project release of jdk11u.
This means it does not profit from a few small enhancements that Oracle have added to the version of OpenJDK used to build their own GraalVM downloads.
Most of these enhancements are to the JVMCI module that allows the Graal compiler to be run inside OpenJDK.
The others are small cosmetic changes to behaviour.
These enhancements may in some cases cause minor differences in the progress of native image generation.
They should not cause the resulting images themselves to execute in a noticeably different manner.
Mandrel's native-image depends on the following packages:
freetype-devel
gcc
glibc-devel
libstdc++-static
zlib-devel
On Fedora/CentOS/RHEL they can be installed with:
dnf install glibc-devel zlib-devel gcc freetype-devel libstdc++-staticNote: The package might be called
glibc-staticorlibstdc++-develinstead oflibstdc++-staticdepending on your system.
If the system is missingstdc++,gcc-c++package is needed too.
On Ubuntu-like systems with:
apt install g++ zlib1g-dev libfreetype6-dev11. Docker image details:

15. Frequently Asked Questions (FAQ)
15.1. Is this project OpenSource?
Yes, you can use this project in anyway you like. Feel free to copy, fork or do whatever you like with it.
If you have questions about licensing, feel free to email me.
15.2. How can I contact the maintainer?
if you have questions, feel free to send me an email: github@ochmanski.de
I will be happy to help you.
15.3. Is this image compatible with AWS CodeBuild pipeline?
- yes, you could use it in the AWS environment, but you just need to install AWS-CLI.
I already prepared a shell script./scripts/install/05-install-aws-cli.shand10-import-rds-certificates.sh.
Simply run it and you should be able to authenticate with all AWS resources.
As an alternative, you may re-build the image from source and invoke the script directly from theDockerfile.
The result will be the same.
