One important improvement in #Kamal 2.x is that #curl is no longer required for your #Docker images in order to perform health checks. That way way you can use slim base images, e.g. @bellsoft.bsky.social 's Alpaquita based image for Liberica #Java, e.g. jdk-25-cds-slim-musl ☕.

Buildpacks with Alpaquita Linux and Liberica JDK 25 are now available! If you use #Paketo buildpacks with @spring.io , you can set the builder to bellsoft/buildpacks.builder:musl and enjoy the instant image size reduction!✨
