> Most of the development and testing of this project was (as of early March 2017) done <b> on Docker Linux containers</b> running in development machines with "Docker for Windows" and the default Hyper-V Linux VM (MobiLinuxVM) installed by "Docker for Windows".
The <b>Windows Containers scenario is currently being implemented/tested yet</b>. The application should be able to run on Windows Nano Containers based on different Docker base images, as well, as the .NET Core services have also been tested running on plain Windows (with no Docker).
The app was also partially tested on "Docker for Mac" using a development MacOS machine with .NET Core and VS Code installed, which is still a scenario using Linux containers running on the VM setup in the Mac by the "Docker for Windows" setup. But further testing and feedback on Mac environments and Windows Containers, from the community, will be appreciated.
## Kubernetes
The k8s directory contains Kubernetes configuration for the eShopOnContainers app and a PowerShell script to deploy it to a cluster. Each eShopOnContainers microservice has a deployment configuration in `deployments.yaml`, and is exposed to the cluster by a service in `services.yaml`. The microservices are exposed externally on individual routes (`/basket-api`, `/webmvc`, etc.) by an nginx reverse proxy specified in `frontend.yaml` and `nginx.conf`.
### Prerequisites
* A Kubernetes cluster. Follow Azure Container Service's [walkthrough](https://docs.microsoft.com/en-us/azure/container-service/container-service-kubernetes-walkthrough) to create one.
* A private Docker registry. Follow Azure Container Registry's [guide](https://docs.microsoft.com/en-us/azure/container-registry/container-registry-get-started-portal) to create one.
* A Docker development environment with `docker` and `docker-compose`.
* Visit [docker.com](https://docker.com) to download the tools and set up the environment. Docker's [installation guide](https://docs.docker.com/engine/getstarted/step_one/#step-3-verify-your-installation) covers verifying your Docker installation.
* The Kubernetes command line client, `kubectl`.
* This can be installed with the `az` tool as described in the Azure Container Service [walkthrough](https://docs.microsoft.com/en-us/azure/container-service/container-service-kubernetes-walkthrough). `az` is also helpful for getting the credentials `kubectl` needs to access your cluster. For other installation options, and information about configuring `kubectl` yourself, see the [Kubernetes documentation](https://kubernetes.io/docs/tasks/kubectl/install/).
### Deploy the application with the deployment script
1. Open a PowerShell command line at the `k8s` directory of your local eShopOnContainers repository.
1. Ensure `docker`, `docker-compose`, and `kubectl` are on the path, and configured for your Docker machine and Kubernetes cluster.
1. Run `deploy.ps1` with your registry information. The Docker username and password are provided by Azure Container Registry, and can be retrieved from the Azure portal. For example:
>```
>./deploy.ps1 -registry myregistry.azurecr.io -dockerUser User -dockerPassword SecretPassword
>```
The script will build the code and corresponding Docker images, push the latter to your registry, and deploy the application to your cluster. You can watch the deployment unfold from the Kubernetes web interface: run `kubectl proxy` and open a browser to [http://localhost:8001/ui](http://localhost:8001/ui)
## Orchestrators: Kubernetes and Service Fabric
See at the Wiki the posts on setup/instructions about how to deploy to Kubernetes or Service Fabric in Azure (although you could also deploy to any other cloud or on-premises).
## Sending feedback and pull requests
As mentioned, we'd appreciate to your feedback, improvements and ideas.
