Customizable containerization framework system and method
Systems and methods for containerization are provided. Various embodiments provide containerization systems and methods deploying an initial container image associated with a startup script, a pre-service script and post-service script. This deployment includes executing the startup script associated with the initial container image, and the executing including copying configuration information for the initial container image into a volume and generating a marker file for the initial container image. The containerization systems and methods also deploying a main container image associated with a startup script.
