Container is a standard unit of software that bundles application or feature and all of its dependencies so that application can be deployed quickly and reliably on any new system that has container host. Looking for an Expert Development Team? There are benefits in implementing API Gateway for large & Complex Microservices based Applications. Great tutorial. Step 3 Since we used API template to generate this project, there should be a WeatherForecastController.cs and WeatherForecast.cs files in the project. Synchronous and Asynchronous Communication . Docker containers (for Linux and Windows) simplify deployment and testing by bundling a service and its dependencies into a single unit, which is then run in an isolated environment. Step 5 We have created our customer entity. Step 11 Now add a new controller in the controller folder with read/write option. Stay updated!
