Deployment Manual / Version 2404
Table Of ContentsOne of the major inventions Docker brought to software development is the ability to package applications as layers of filesystems, that when stacked upon each other result in the final application image. This technique allows docker to reuse and share common parts between multiple images at build and startup time and reduces the disk and network footprint drastically.
In the CoreMedia Docker setup, this technique is used by providing a common base image on the public DockerHub
repository. The java-application-base image is the common base
image for all our Spring-Boot application based images. It encapsulates our best practice to configure, start and manage
CoreMedia applications in most secure way. It is provided in different flavors for different JDK base images on DockerHub
and it is possible to fork the source repository on
GitHub, to build a customized image.
To summarize the capabilities of the image, it provides:
A JVM to run our applications
A startup script chain to integrate arbitrary initialization steps before starting the Spring-Boot application
A set of convenient script chain steps to let applications delay their startup until service dependencies are available
A monitoring integration for Prometheus
