Dockerisation

  • at leat 2 steps
    1. step create docker files ( 1 or more, in the worst case N where N is number of apps )
    • start with alpine linux
    • so we have dockerfile (container)
    • container goes to artifactory docker repository
    1. use docker containers within Kubernetes Helm Charts
    • you start with appp container (image)
    • using Helm create from templates Charts for apps (?? not sure how many , in best case one parametrized resusable template, maybe N where N is nubmer of apps)
    • this functionality will do Jenkins ( heml cli or ku .. ) or our REST Spring Boot service
    • Charts should go to artifactory HElm repository + Here Container Repository
