Unofficial docker image available for Amazon Linux 2023

Community Showcase
1

i have managed to compile a swift 5.9.2 release toolchain for Amazon Linux 2023, and have pushed a (2GB) docker image here: tayloraswift/5.9.2-amazonlinux2023

note that to compile anything in release mode, it is necessary to pass -Xswiftc -use-ld=ld to the swift build invocation, because of incompatibility between ld.gold and libstdc++.

for the sake of transparency, building this image invoked three dockerfiles:

dockerfile 1

dockerfile 2

FROM tayloraswift/swift-ci:amazonlinux2023

RUN mkdir swift-project
WORKDIR swift-project

ARG SWIFT_CHECKOUT=main
