Working with Red Hat Fuse 7 on Spring Boot is straightforward. In my field experience, I have seen many development (a.k.a. integrator) teams moving to Fuse 7 on Spring Boot for their new integration platforms on Red Hat OpenShift Container Platform (well aligned with agile integration).
Lately, however, I have also seen some teams worried about the size of the final images and the deployment pipeline. In most cases, they had developed a set of common libraries or frameworks to extend or to homogenize the final integration projects. All the cases have the same result:
- Several dependencies copied in each integration project
- Always replacing the container images with the latest fat JAR (including the same dependencies) in each build pipeline
Spring Boot is usually packaged as “fat JARS” that contain all runtime dependencies. Although this is quite convenient, because you only need a JRE and a single JAR to run the application, in a container environment such as Red Hat OpenShift, you have to build a full container image to deploy your application.
