Camel on Quarkus

a build time toolkit

Why Camel on Quarkus?

 

💾 Small size on disk ✓ Small container images
🚀 Fast boot time ✓ Instant scale up
🔬 Low memory footprint ✓ More containers with the same
amount of RAM

    • quarkus-container-image-jib
    • quarkus-container-image-docker
    • quarkus-container-image-s2i

  • Generate Kubernetes resources
    • quarkus-kubernetes
    • quarkus-minikube
    • quarkus-openshift
    • quarkus-kubernetes-config
