Deploying Istio

Install {istio} by following the instructions in the official {istio} Getting started documentation.

Run the following command to verify that the istioctl path was set successfully:

istioctl version

The output will be similar to the following example:

no running Istio pods in "istio-system"
1.24.2

Run the following command to configure the {istio} profile on {kube}:

istioctl install --set profile=demo

The following output appears when the installation is complete:

✔ Istio core installed
✔ Istiod installed
✔ Egress gateways installed
✔ Ingress gateways installed
✔ Installation complete

Verify that Istio was successfully deployed by running the following command:

kubectl get deployments -n istio-system

All the values in the AVAILABLE column will have a value of 1 after the deployment is complete.

NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
istio-egressgateway      1/1     1            1           2m48s
istio-ingressgateway     1/1     1            1           2m48s
istiod                   1/1     1            1           2m48s

Ensure that the {istio} deployments are all available before you continue. The deployments might take a few minutes to become available. If the deployments aren’t available after a few minutes, then increase the amount of memory available to your {kube} cluster. On Docker Desktop, you can increase the memory from your {docker} preferences. On {minikube}, you can increase the memory by using the --memory flag.

Finally, create the istio-injection label and set its value to enabled:

kubectl label namespace default istio-injection=enabled

Adding this label enables automatic {istio} sidecar injection. Automatic injection means that sidecars are automatically injected into your pods when you deploy your application.
