Setup Istio on IKS

Using the IBM Cloud Developer Tools CLI

Create a Standard Cluster,

  • Login into IBM Cloud,

$ ibmcloud login -u <username> -p <password> -r us-south -g Default
$ ibmcloud target --cf

  • To create a Standard Cluster, you must specify the zone, flavor (or machine-type), public VLAN and private VLAN.

  • First, find the available zones,

$ ibmcloud ks zones
OK
Zone   
ams03   
che01   
hkg02   
mel01   
mex01   
mil01

osl01

syd05   
tok02

wdc04   
wdc06   
wdc07

  • Then, find the available flavors (or the deprecated term machine-types) in a selected zone, e.g. dal10,

$ ibmcloud ks flavors --zone dal10 
OK
For more information about these flavors, see http://ibm.biz/flavors

  • Then, find the public and private VLANs,

$ ibmcloud ks vlan ls --zone dal10
OK
ID        Name   Number   Type      Router         Supports Virtual Workers   
1234567          1593     private   bcr03a.dal10   true   
2345678          1519     public    fcr03a.dal10   true

  • Now, with the zone, flavor (or machine-type), public VLAN ID and private VLAN ID, create the Standard Cluster,

$ ibmcloud ks cluster create classic --name <account>_iks_cluster_<user> --zone dal10 
--machine-type b3c.4x16 --hardware shared --workers 3 --public-vlan 2345678 
--private-vlan 1234567

OK

  • Check the status of your available clusters,

$ ibmcloud ks cluster ls
OK

  • Check the status of your worker nodes,

$ ibmcloud ks worker ls --cluster account1_iks_cluster_user1

  • Wait until the State is normal and the Status is ready,

Enable the Istio Add-on,

  • Enable the istio add-on, and optionally the istio-extras and istio-sample-bookinfo add-ons.

  • Enable the istio add-on,

$ ibmcloud ks cluster addon enable istio --cluster account1_iks_cluster_user1
Enabling add-on istio for cluster account1_iks_cluster_user1...
OK

  • Enable the istio-extras,

$ ibmcloud ks cluster addon enable istio-extras --cluster account1_iks_cluster_user1
Enabling add-on istio-extras for cluster account1_iks_cluster_user1...
OK

  • Enable the istio-sample-bookinfo,

$ ibmcloud ks cluster addon enable istio-sample-bookinfo --cluster account1_iks_cluster_user1
Enabling add-on istio-sample-bookinfo for cluster account1_iks_cluster_user1...
OK

  • Verify that the managed Istio add-ons are now enabled,

$ ibmcloud ks cluster addon ls --cluster account1_iks_cluster_user1
OK
Name                    Version   
istio                   1.3.3   
istio-extras            1.3.3   
istio-sample-bookinfo   1.3.3

Using the IBM Cloud UI

Create a new IBM Kubernetes Service (IKS) cluster on IBM Cloud,

  • Login to your account on IBM Cloud,

  • Go to the Catalog,

  • Search the catalog for Kubernetes Service,

  • Select the Kubernetes Service,

  • Click the Create button,

  • Select the Standard plan, a Managed Istio add-on is not available for a free cluster,

  • Optionally, rename the Cluster name, e.g. <username>-standard-iks-cluster,

  • Optionally, select a Single zone location,

  • Click Create cluster,

  • It will take a while before the provisioning of the cluster has been completed,

Once the cluster is available, enable the Istio Add-on:

  • In the Clusters > Kubernetes Service,

  • Go to the Add-ons tab,

  • Install the Managed Istio add-on,

  • Click Install,

  • Select all options including Istio v1.3.2 , Extras, and Sample,

  • Click Install,

Note that you have installed Istio v1.3.2, we will use the Istio release including the Sample - Bookinfo application in the rest of the examples.
