This course serves as a accelerator program to understand, setup and master openshift container platform for professionals who already have an understanding of docker and kubernetes.
- This course is for someone who has already taken docker fundamentals, and kubernetes bootcamp courses/have equivalent knowledge, and would like to learn how to leverage Openshift Platform which is an abstraction on top of it.
- If you are a Operations/Systems personnel and would like to learn how to build a production grade scalable, fault tolerant and high available openshift infrastructure, and administer it, this course it for you.
- If you are a developer and would like to learn how to deploy your application stacks in production, on top of paas solution and also understand the underlying primitives, this course is for you.
- You could be developer/operations personnel and be in charge of securing application infrastructure and setup auxiliary services such as monitoring, centralized logging etc. this course is for you.
- If you are a advanced user of Openshift already, this course is definitely not for you.
- If you are interested in learning docker/container orchestration on windows, this course is not ideal for you as it focuses on linux containers.
- This is mix course for both developers and operations. If you are looking for a course which is very specific to an audience e.g. administrators or developers, ask for a custom outline.
As part of this course you will,
- GO through the theory to learn what is openshift platform, the core concepts relates and the advantages of using it.
- Install and configure a simple(non HA) multi node Openshift cluster with ansible. You would also have a conceptual understanding of how to build a production quality cluster with high availability, scalability, redundancy and security considerations.
- Learn how to deploy, configure, interconnect and publish and scale applications as well as isolate those with multi tenant environments that openshift provides and underlying kubernetes primitives that it leverages.
- Achieve Continuous Integration and Delivery with openshift's integration with git, jenkins and its implicit primitives including builds, pipelines and image streams.
- Learn how to manage persistent storage in a openshift environment
- Learn about the network and security considerations and features offered by Openshift.
- Learn openshift administration tasks such as setting up quotas, managing memberships, monitoring etc.
Even though this course covers many concepts related to kubernetes, since its a very vast topic, it still has the following areas uncovered.
- Cloud specific provisioning and integration
- HA installation of a kubernetes cluster with multi masters
- In depth openshift administration
- Writing Micro Services Applications
- Alternate container runtimes e.g. rocker/rkt, runc
Following are the pre requisite skills to attend this course. Since its a beginner level course, no prior experience with linux containers is assumed.
You should have attended the following course, or have demonstrable knowledge with the topics included in the following course.
- Docker Fundamentals
