19. GOAL FOR LAB
In this lab you will learn:
● Important OpenShift concepts for developers
● How OpenShift makes developers and architects happier
● How to do efficient round-trip development:
○ Separate dev from prod environments
○ Quick deployments using rsync / port-forwarding
○ Promoting apps using CI/CD Pipelines
20. LAB: DEVELOPER INTRO TO OPENSHIFT
SCENARIO 3 A DEVELOPER INTRODUCTION TO OPENSHIFT
WEB: openshift-modernize-apps.katacoda.com
22. RESULT OF LAB
In this lab you learned how to:
● Do quick deployments with oc rsync
● Create a production environment separate from dev
● Promote tested/verified builds between environments using
OpenShift pipeline builds
You should now have two projects (dev and prod) running the
same CoolStore app! In the next lab we will begin the process of
breaking the monolith up into microservices.
Red Hat OpenShift is a complete container application platform that natively integrates technologies like docker and Kubernetes to provide a common platform for developers to build and manage containerized applications in a self-service fashion. It builds on top of Red Hat Enterprise Linux or Atomic Host, the trusted enterprise operating system which is used by 90% of Fortune 500 companies, and provides tools and services for building container images from source code and application binaries and managing their lifecycle in production at scale.
Red Hat is a leader in both Kubernetes and docker community and is a top contributor to both communities to make sure these technologies fit smoothly to the needs of customers and users for building microservices on OpenShift.
Specifically for microservices, OpenShift provides a large set of capabilities to take the complexity out of building and running distributed systems at scale. It provides
Service discovery for services find each other despite other services popping up and down as they scale or get deployed and undeployed.
Routing and load balancing to be able to send traffic to the microservices and control how the traffic is distributed between multiple instances of the application enabling patterns like A/B testing
Metrics and monitoring to make sure you can identify anomalies as a microservice starts to misbehave to consume too much resources
Configuration and secret management to decouple environment specific data from the microservices and be able to provide both configuration and also sensitive data in a secure manner to them from environment to environment without the need to change the microservice itself.
Central log management so that when microservices get undeployed or issues occur, the historic logs are kept and inventories in a central place for further investigation.
Service isolation and granular access control to make sure microservices are only allowed to access and do what they are allowed to. Besides, it encourages collaboration by allowing for example developers to look into production without having access to make a change if that’s how your organization operates.
OpenShift is the only platform in the market that provides multi-tenancy on top of Kubernetes and allows all teams and developers to work and collaborate on the same platform without the risk of interfering with each other projects or services.
Developers will want to access learn.openshift.com where we have set up a number of self-paced hands-on scenarios that don’t require installation of any software, and completely runs in your browser. You’ll find scenarios for the runtimes I discussed today, as well as scenarios to learn more about how OpenShift itself works.
