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.

Obtaining and installing the lab tools on non-Windows 7 platform

You have done these installation steps, you may go to the next section. You only do these tasks once.

If you have a Microsoft Windows 7 platform, do not perform these steps. IBM can set up a vm-based environment for your use in the labs.

To install Container/Kubernetes related tools on your local machine,

  1. Docker Toolbox (select your platform from the left-side menu for instructions for Linux, MacOS, Microsoft Windows): https://docs.docker.com/install/

  2. Git scm ( if installing on Windows, the git bash shell can be handy too ) https://git-scm.com/downloads

  3. IBM Cloud stand-alone CLI: https://cloud.ibm.com/docs/cli/reference/ibmcloud?topic=cloud-cli-install-ibmcloud-cli

  4. Installing plugins for the CLI. After installing the IBM Cloud CLI, run these two commands to install the kubernetes and container registry plugins:

    ibmcloud plugin install kubernetes-service -r Bluemix    

ibmcloud plugin install container-registry -r Bluemix

    For both of these binaries, copy the code (after unpacking if it is a tarball) to your system path.

  5. Install kubectl (our clusters will be set with 1.13.6 - but latest of 1.14 will be ok) https://kubernetes.io/docs/tasks/tools/install-kubectl/

  6. Install helm https://github.com/helm/helm/releases/tag/v2.14.0

  7. Install Istio https://istio.io/docs/setup/kubernetes/download/

Preparing your lab environment (terminal, command window, power shield and etc)

If you have done the tasks in this section and are still using the same terminal/command window, you may start the lab by following the lab repo link at the end of this document.

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. 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.

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.

  2. Target the AppMod-AA-RG namespace:

    ibmcloud target -g AppMod-AA-RG

  3. 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

  4. 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. Note $USER automatically resolves to the user logged into the terminal environment.

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

    Note: if the above command produced syntax error in your environment, you may manually execute command ibmcloud ks cluster-config --cluster $USER-cluster first. Then, take its output as the next command and execute it in the same window.

  5. 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.

  6. Verify that you have the appmod_aa namespace.

    ibmcloud cr namespaces
Listing namespaces...

Namespace   
appmod_aa

OK

  7. 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'.

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

    ibmcloud cr images
