Also installable via your favorite package manager, istioctl is an important CLI for service operators to debug and diagnose their Istio service mesh.Įxample 4-6. Irrespective of which OS you use, after you’ve downloaded the distribution for your OS, extract the compressed file to a directory and familiarize yourself with the contents of the distribution.Įach release includes istioctl (this binary will be specific to your OS), configuration samples, a sample application, and platform-specific installation resources. You can choose from Windows, macOS, and Linux releases.

You can also download Istio from the Istio release page. To fetch a particular version of Istio, specify the desired version number, as shown here: $ curl -L | ISTIO_VERSION=1.1.0 sh -Įven though Istio as a project provides backward compatibility from minor version to minor version (unless noted in release changelogs), you might want to specify ISTIO_VERSION=1.1.0 to ensure that the examples in this book function as described.

Windows users may need to download curl for Windows. Mac and Linux users should find curl readily available on their system. kubectl makes Dashboard available, as illustrated in Figure 4-2. See kubectl proxy -help for more options and Kubernetes Dashboard documentation for more information. Understand that you can access Dashboard only from the machine where the command is executed. This command creates a local web server that securely proxies data to Dashboard through the Kubernetes API Server. Then access Dashboard by using the kubectl command-line tool by running the following command: $ kubectl proxy Master/aio/deploy/recommended/kubernetes-dashboard.yaml Deploy the Kubernetes Dashboard by running the following command: $ kubectl create -f The easiest and most common way to access the cluster is through kubectl proxy, which creates a local web server that securely proxies data to Dashboard through the Kubernetes API Server. Dashboard is useful for reinforcing your understanding of how Istio is running. Kubernetes Dashboard also provides information on the state of Kubernetes resources in your cluster and on any errors that might have occurred. You can use it to deploy and troubleshoot containerized applications. Kubernetes Dashboard is a web-based UI for managing your cluster and its resources. There are a couple of ways you can do this, depending upon whether you’re using a package manager like Helm or simply Kubernetes spec files directly. Instead of increasing the amount of memory allocated to your Docker Desktop installation, as shown in Figure 4-1, you might, alternatively, reduce the amount of memory that Pilot requests of your Kubernetes cluster. Docker Desktop’s default limit also happens to be 2 GB, so Pilot might refuse to start due to insufficient resources, if this isn’t increased in your Docker installation. Pilot, specifically, might have trouble running as it requests 2 GB of memory in an Istio deployment with default settings (for a quick review of Pilot’s purpose, see Chapter 3). This amount of memory allocation is required for all Istio and Bookinfo services to run. To ensure that your Docker Desktop VM has enough memory to run Kubernetes, Istio, and Istio’s sample application, Bookinfo, you will need to configure your Docker VM with at least 4 GB of memory. For more information about kubectl, see the official documentation.

This location might not be in your shell’s PATH variable if so, type the full path of the command or add it to the PATH. The Docker Desktop for Windows Kubernetes integration provides the Kubernetes CLI executable at C:\>Program Files\Docker\Docker\Resources\bin\kubectl.exe. The Docker Desktop for Mac Kubernetes integration provides the Kubernetes CLI executable at /usr/local/bin/kubectl. The Docker Desktop–managed Kubernetes server runs locally within your Docker instance, is not configurable, and is a single-node Kubernetes cluster. We use Docker Desktop to run Kubernetes and Kubernetes as the platform to deploy Istio. For a list of supported platforms, see the Istio documentation.Īs of July 2018, Docker Desktop for Mac and Windows includes support for running a standalone Kubernetes server and client as well as Docker CLI integration. No matter which tool you use to deploy Istio, the examples used here should work within any Istio environment running on Kubernetes. You can also use the management plane, Meshery, which quickly deploys Istio and the sample application, Bookinfo.

We chose Docker Desktop as a convenient Kubernetes platform that requires manual deployment of Istio (so you can see Istio’s innards without needing to fuss with Kubernetes cluster deployment).
