Last month I attended a course about Container Orchestration in IBM Office, in Ehningen Germany. What I learned were pretty much basics for the IBM Cloud, the course lasts for a day and I did not expect to get any in depth knowledge.
If you would like to take a look at Docker, Kubernetes, Helm, IBM Public and Private Cloud, this is good place to start. This is a fast-paced course, where you can gather a ton of information and material in order to jump start your knowledge about Containerization and IBM Cloud. I highly recommend this course for everyone interested in this technology. Official course description:
