Getting Started
This section requires basic understanding of Kubernetes - make sure you do the tutorial in sequence.
You need to get the
istioctl CLI to install Istio into the cluster.cd $HOME
# Specify an Istio version to install
curl -L https://istio.io/downloadIstio | \
ISTIO_VERSION=1.7.4 sh -
Add Istio's
bin path to shell's PATH.echo 'export PATH="$PATH:$HOME/istio-1.7.4/bin"' >> ~/.bash_profile
source $HOME/.bash_profile
Verify
istioctl is installed properly and with the correct version:istioctl version
Install the
demo profile of Istio, which comes with the basic settings for most of the things you'll want to learn about. In addition, because the cluster in this guide enabled Network Policy, so we can use Istio with Container Network Interface (CNI).istioctl install \
--set profile=demo \
--set values.cni.cniBinDir=/home/kubernetes/bin \
--set components.cni.enabled=true \
--set components.cni.namespace=kube-system
Validate that Istio is installed.
istioctl version should show you the control plane version.istioctl version
In addition, Istio is installed into the
istio-system namespace.kubectl get ns
kubectl -n=istio-system get pods
In addition to core-Istio, you can install addons for observability, for example to see distributed traces and out-of-the-box metrics/dashboard.

# Prometheus
kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.7/samples/addons/prometheus.yaml
# Grafana
kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.7/samples/addons/grafana.yaml
# Wait for Grafana a bit before Kiali
sleep 20
# Kiali
kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.7/samples/addons/kiali.yaml
