This document discusses developing and deploying microservices on IBM Cloud Private. It provides an overview of IBM Cloud Private including its architecture, editions, and included content. It also covers Kubernetes concepts like pods and services. Helm is introduced as a tool for managing Kubernetes applications and charts. Finally, an example application called Stock Trader is presented to demonstrate how a hybrid cloud application could be built on IBM Cloud Private.

4. Everyone’s container journey starts with one container…

5. At first the growth is easy to handle….

6. But soon it is overwhelming… chaos reigns

7. Regain control with Kubernetes

8. What is Kubernetes?
• Container orchestrator
• Runs and manages containers
• Supports multiple cloud and bare-metal environments
• Inspired and informed by Google's experiences and internal systems
• 100% Open source, written in Go
• Manage applications, not machines
• Rich ecosystem of plug-ins for scheduling, storage, networking

Nodes – hosts that run
Kubernetes applications
Master nodes:
•Controls and manages the cluster
•Kubectl (command line)
•REST API (communication with workers)
•Scheduling and replication logic
Worker nodes:
•Hosts the K8s services
•Kubelet (K8s agent that accepts commands
from the master)
•Kubeproxy (network proxy service responsible
for routing activities for inbound or ingress
traffic)
•Docker host

11. Kubernetes Workloads
/* Discover. Collaborate. Deploy. */ 11
Pods:
•Smallest deployment unit in K8s
•Collection of containers that run on a
worker node
•Each has its own IP
•Pod shares a PID namespace, network,
and hostname
Service:
•Collections of pods exposed as an
endpoint
•Information stored in the K8s cluster state
and networking info propagated to all
worker nodes

14. Helm- Introduction
/* Discover. Collaborate. Deploy. */ 14
Helm helps you manage Kubernetes applications — Helm Charts helps you define,
install, and upgrade even the most complex Kubernetes application.

15. Charts, Repositories and Releases
/* Discover. Collaborate. Deploy. */ 15
• Charts: A bundle of
Kubernetes resources
• Repository: A collection of
charts.
• Releases: A chart instance
loaded into Kubernetes . Same
chart can be deployed several
times and each becomes its
own release

16. Charts Package
/* Discover. Collaborate. Deploy. */ 16
• Application definitions
- Metadata (chart.yaml)
- Documentation
- Kubernetes templates
- Configuration files
(values.yaml)
• A chart can have
dependencies on other charts

17. IBM Cloud Private transforms the way IT
operations and developers work

Todd
Operations / Admin
Responsible for infrastructure, security, and
management of the environment.
Jane
Enterprise Developer
Responsible for modernizing existing applications and
creating new Cloud Native Workloads.
IT Operations and Administrators
•Quickly set up a modern, flexible,
and compliant private cloud
•Integrate with existing
management tools and processes
Developers
•Rapidly create new cloud-native
applications, optimize existing
ones, and securely connect their
applications with data and services
across all clouds

“I want to Improve my app”
Product leaders want to improve their Stock Trader application to increase client satisfaction
“I want continuous delivery – built with microservices”
Development leads demand greater flexibility with microservices and continuous delivery that only
Cloud can give them
“I need sensitive data to stay local”
Lead administrators need the data and workload to stay local, wants to manage the cloud, yet does
not want to be burdened with complicated operations
