5. Preparation for the
Katacoda Hands-On Labs
• Arrange access to Oracle Cloud Infrastructure
Tenancy
• Existing or new OCI Cloud Trial
• Existing OCI tenancy
• Go to http://bit.ly/real-oci
home of the REAL Katacoda scenarios for OCI
• Run First Scenario to prepare the OCI tenancy
for REAL Katacoda OCI Scenarios
• Provision an OCI compartment and some
resources
• Prepare auth token, key pair and config file
for using the OCI CLI in other scenarios
Go http://bit.ly/real-oci

6. Cloud Trial

8. Preparation for OKE Scenarios
• Provision a new Kubernetes cluster (in less
than 12 minutes) (First Part)
• Provision a Compute Instance with an NGINX
server that will perfom as reverse proxy for
the API Server (K8s) (Second Part)
• Connect to the cluster and work with it
(Third Part)
• Connect to the Cluster
• Create a namespace
• Deploy services
• Create services
• Scale your services

9. Understanding the services
• The scenario is going to provide an
authentication service
• The Service will provide:
• The ability to authenticate a user and generate a
token
• The ability to retrieve the user profile
• The ability to refresh the token
• The Service will be Golang based
• Service has the logic to retrieve the profile,
generate a new token or refresh it
• REDIS is used to store the tokens and
manage their lifecycle

Now we can connect through this reverse proxy using port 443

13. Why and What a Kubernetes scenario?
• K8s is the foundation for Cloud Native
• Oracle has an offering for that. We want you to try it and test it
• OKE runs on top of OCI. Is a first class citizen
• To proof that in less than 60 minutes we can provision and
deploy services
• Deploy a REDIS Cluster
• Create a Go based API to simulate an authentication Service
• Deploy the API in the cluster
• Test the API
• Scale your API
