You can apply authorization rules based on the client identity, which is useful for restricting access to key components. Each component of the voting app uses its own Kubernetes service account, and Istio uses the service account to authenticate - so services know the identity of clients making network calls. Istio can encrypt network traffic and apply authentication and authorization rules. You can continue the canary rollout by altering the route weights in the YAML file. Istio listens for all incoming traffic on port 5000, and sends it to a pod based on the routing rules. The Kubernetes YAML file you applied contains Istio routing rules which send 70% of traffic to the v1 voting site, and 30% to v2. Refresh a few times and you’ll sometimes see the original v1 site and sometimes this new v2 site: We’ll use it for a canary rollout of a new version of the vote component:īrowse to again and you’ll see the voting page. You can use that for dark launches of new features and blue-green deployments. You can set up routing rules to send traffic to a different target from the one the client actually requested. Istio’s main feature is traffic management. Right now all the communication is going through Istio, but it’s not doing anything much because we haven’t configured any Istio resources. You can cast a vote at and see the results at It’s a distributed app which uses a Redis message queue for communication and a Postgres database for storage - with application components written in Python. The app you’re running is the Docker sample voting app. Each pod has one application container and one network proxy container, injected by Isito. You’ll see 2/2 in the READY column for all the pods, which is the number of running containers. Exit out of the watch command with Ctrl-C. When all the pods have a status of Running, the app is good to go. The Istio demo application manifest runs all the features of Istio and it works in the same way on Docker Desktop or on a multi-node Kubernetes cluster in the cloud: You can deploy it in different ways (typically using the Istioctl command line, or with the Meshery tool if you’re comparing different service meshes), but the simplest is with kubectl. Istio runs as a Kubernetes application itself. Under the Resources tab increase the memory slider to at least 6GB - increasing CPU cores to at least 2 would be good too:

Click on the Docker whale icon in the taskbar on Windows or the menu bar on Mac and click Settings. Istio runs in containers and you’ll need to give Docker Desktop some extra memory so it can run everything. You’ll need Docker Desktop installed with Kubernetes running - you can follow the steps from the lab Getting Started with Kubernetes on Docker Desktop. You’ll gain experience of some of the core features of Istio: using traffic management for canary deployments, applying encryption in transit with service authorization, and monitoring communication.

DOCKER ENABLE KUBERNETES HOW TO

In this lab you’ll learn how to deploy the demo installation of Istio on Docker Desktop and run a simple demo app. It’s an architecture which works really well for distributed applications running in containers on Kubernetes, and you can try it out using Docker Desktop.

Docker: Docker Desktop – Community 20.10.Istio is a service mesh - a software component which manages the network communication for your applications.kube folder in C:\Users\ (or rm -rf ~/.kube) Delete pki folder in C:\Users\\AppData\Local\Docker (or rm – rf ~/Library/Group Containers//pki in mac).What happen is, Kubernetes stuck at starting endlessly.Ĭannot get lease for master node: an error on the server (“”) has prevented the request from succeeding (get docker-desktop) Here comes the problem, and I think the problem happens only if you use and run container before activating Kubernetes (Kubernetes is activated later after a while you use container function).

In order to enable Kubernetes just enable it from settings and restart your Docker Desktop, it might take a while to download all the Kubernetes assets. The setup was quite easy, just a few ticks on settings as shown. NETCore container (another topic, another day perhaps), it’s time to level up the game to use orchestrator.įirst one I choose to play with is Kubernetes (K8) since it’s included in Docker Desktop for Windows (or MacOS). Playing with docker is quite fun, deploying microservices as a container is also fun. Microservice and containerization is the next future, at least when this article is written.
