from the command list that appears and select the Node sample from the list. To create a Docker container, we are going to open a GitHub repository with a Node.js project.
#Istio docker for mac code#
The Remote Status bar item can quickly show you in which context VS Code is running (local or remote) and clicking on the item will bring up the Remote - Containers commands. With the Remote - Containers extension installed, you will see a new Status bar item at the far left.
#Istio docker for mac install#
Install the Remote - Containers extension The Remote - Containers extension lets you run Visual Studio Code inside a Docker container. Once Docker is running, you can confirm that everything is working by opening a new terminal window and typing the command: docker -version # Docker version 18.09.2, build 6247962 Install the extension You can click on the icon to see the status. If the whale icon is animated, it is probably still in the process of starting. You will know it's running if you look in the activity tray and see the Docker whale icon.ĭocker might take a few minutes to start. Run the Docker Desktop application to start Docker. Docker Desktopĭownload and install Docker Desktop. Install Dockerĭocker is needed to create and manage your containers. Running VS Code inside a Docker container can be useful for many reasons, but in this walkthrough we'll focus on using a Docker container to set up a development environment that is isolated from your local environment. You need no prior knowledge of Docker to complete this tutorial. This tutorial walks you through running Visual Studio Code in a Docker container using the Remote - Containers extension.
That is all and with running the istioctl install -f install-istio.yaml command we kick off the Istio deployment.Īfter a couple of minutes Istio got successfully installed. Therefore, we must switch to the type NodePort to expose the ingress gateway on the localhost / host interface. Per default the ingress gateway uses the service type LoadBalancer which do not work on KinD as an SLB (Software Load Balancer) implementation is missing. Same as for istiod I am setting the HPA maxReplicas to 1 and adjusting the PodDisruptionBudget.įurthermore, I specify a nodeSelector ensuring, in case of a KinD multi node cluster, that the Istio ingress gateway always runs on a particular node. Next stop is the Istio ingress gateway configuration as seen above.
#Istio docker for mac upgrade#
Otherwise an Istio upgrade would not succeed as we never fulfill the PodDisruptionBudget.
Let us start now with the configuration settings I am using for Istio on a KinD single node cluster.įor the istiod component I am setting the HPA maxReplicas to 1 having enough spare capacity for my workloads.Ī requirement then is to use an overlay overwriting the PodDisruptionBudget and set it to 0. I made a configuration decision for KinD in this case using the extraPortMappings option to pin port 80, 41 onto specific ports in the Kubernetes NodePort range. I mentioned also Istio and today we walk through the configuration to get it running on Kubernetes in Docker.Īs prerequisite I recommend reading my previous blog post before you continue with this one. In my last blog post I have shown you my local Kubernetes setup with KinD.
