Helm Hands-on Lab

Lab Pre-requisites

For the hands-on labs of this workshop, you will need to either have tools installed on your workstation or use the IBM-provided web terminal. The web terminal has all tools pre-installed. If you are on a Windows 7 platform, or have not yet installed the tools listed below, you should use the web terminal.

Lab Environment Setup

Run these steps inside the console-in-a-browser environment provided by your instructor, or in a terminal/command window on your local machine.

  1. Set environment variables

    export USERNAME=user###

    export MYCLUSTER=$USERNAME-cluster

    Note: replace ### with your assigned ID

  2. Login to the IBM Cloud. When asked to select an account, select "American Airlines' Account". Select 'us-south' as the region.

    ibmcloud login --sso

API endpoint: https://cloud.ibm.com
Region: us-south

Get One Time Code from https://identity-3.us-south.iam.cloud.ibm.com/identity/passcode to proceed.

2. American Airlines (67eaa4b4b0b80862fab45beb6b22f002) <-> 1429869
Enter a number> 2
Targeted account American Airlines (67eaa4b4b0b80862fab45beb6b22f002) <-> 1429869
API endpoint: https://cloud.ibm.com

API endpoint:      https://cloud.ibm.com   
Region:            us-south   
User:              timro@us.ibm.com   
Account:           American Airlines (67eaa4b4b0b80862fab45beb6b22f002) <-> 1429869       
Resource group:    No resource group targeted, use 'ibmcloud target -g RESOURCE_GROUP'   
CF API endpoint:      
Org:                  
Space:                

Tip: If you are managing Cloud Foundry applications and services
- Use 'ibmcloud target --cf' to target Cloud Foundry org/space interactively, or use 'ibmcloud target --cf-api ENDPOINT -o ORG -s SPACE' to target the org/space.
- Use 'ibmcloud cf' if you want to run the Cloud Foundry CLI with current IBM Cloud CLI context.

  3. Target the IksTraining-AA-RG namespace:

    ibmcloud target -g IksTraining-AA-RG

  4. List the clusters and locate the cluster corresponding to the userId you used to login to the console-in-a-browser environment. For example, if you are user028, your cluster will be user028-cluster.

    ibmcloud ks clusters
Clusters at version 1.11 and later run containerd instead of Docker as the Kubernetes container runtime. For more information and update actions, see <https://ibm.biz/Bd22hF>

OK
Name              ID                                 State    Created      Workers   Location          Version       Resource Group Name   
user001-cluster   707f162b19cc4c3bbb28bfbfe85ee873   normal   2 days ago   2         Washington D.C.   1.11.8_1547   IKS-RG1   
user026-cluster   dcfb22a45c8e410e8d6f7a8269c2d0c3   normal   1 day ago    2         Washington D.C.   1.11.8_1547   IKS-RG1   
user028-cluster   1b3398b985d84e9b8e9544a91d61428a   normal   1 day ago    2         Washington D.C.   1.11.8_1547   IKS-RG1   
user029-cluster   6d267a184154407d873f0b02159feb84   normal   1 day ago    2         Washington D.C.   1.11.8_1547   IKS-RG1

  5. Configure your Kubernetes client using this command. This will also configure your Kubernetes client for future login sessions by adding the command into your .bash_profile. Edit the command before running replacing <your user> with the Username from the instructor. For example, if you have user005, the cluster will be user005-cluster.

    eval $(ibmcloud ks cluster-config --cluster $USERNAME-cluster --export | tee -a ~/.bash_profile)

    If the command has a syntax error in your terminal (e.g. windows cmd shell), you may instead run the command ibmcloud ks cluster-config --cluster <your user>-cluster. Then, copy the output and execute it in the same terminal.

  6. You should be able to use kubectl to list kubernetes resources. Try getting the list of pods (there should be none yet)

    kubectl get pods
No resources found.

  7. Verify that you have the ikstraining-aa namespace.

    ibmcloud cr namespaces
Listing namespaces...

Namespace   
ikstraining-aa

OK

  8. Login to the registry service

    ibmcloud cr login
Logging in to 'registry.ng.bluemix.net'...
Logged in to 'registry.ng.bluemix.net'.

IBM Cloud Container Registry is adopting new icr.io domain names to align with the rebranding of IBM Cloud for a better user experience. The existing bluemix.net domain names are deprecated, but you can continue to use them for the time being, as an unsupported date will be announced later. For more information about registry domain names, see https://cloud.ibm.com/docs/services/Registry?topic=registry-registry_overview#registry_regions_local

Logging in to 'us.icr.io'...
Logged in to 'us.icr.io'.

OK

  9. Verify you can list the images in the registry. You should see at least guestbook and mariadb, maybe a couple others.

    ibmcloud cr images --restrict ikstraining-aa
Listing images...

REPOSITORY                                    TAG        DIGEST         NAMESPACE    CREATED        SIZE     SECURITY STATUS

OK

  10. Navigate to the working folder.

    cd /userdata

Verify the connection to IBM Cloud and IKS cluster

To verify the connection to IBM Cloud and IKS cluster,

ibmcloud target

kubectl config view

Lab Repo

Now you have logged into IBM Cloud and connected into your kubernetes cluster, you are ready to proceed to the steps in the lab.

Skip Lab 0 and go directly to Lab 1. You will do lab 1, 2, 3, and 4.
