Deploying a .NET Core Web API microservice on Kubernetes

Prerequisite:

• Docker
• .NET Core 6

to run in production

$ cd Titanic.Api
$ docker-compose up -d

Checking the Readiness and Liveness of the App.

###To check if the API is live sh {url/endpoint}/healt/live ###To check is the database is ready to serve requests sh {url/endpoint}/healt/ready

• The docker-compose.yml is for building both db and api.
• Dockerfile is .NET Core Web API Multistage Dockerfile (following Docker Best Practices)
• appsettings.Development.json is .NET Core Web API development environment config
• kubenertes folder contains Kubernetes yaml files (deployment, statefulstes, services) the webapi image cheloghm/titanic:v26 is the latest and best version while the database image cheloghm/mongo:v4 is a seeded/pre-populated database and the best version. Both images are already implemented in their respective yml files is the Kubernets directory. Just run the comand: sh $ kubectl apply -f kubernetes/mongodb.yaml $ kubectl apply -f kubernetes/mongodb.yaml In your cluster to spin up the service/app.
• Program.cs is .NET Core Web API environment variable mapping config and .NET Core Web API startup & path routing config

Setting Up

To setup this project, you need to clone the git repo

$ git clone https://github.com/cheloghm/C_Solutions.git

### To run in Dev environment 
    ```sh
    $ dotnet run
    ```
    OR
    ```sh
        docker run -it --rm -p 8282:80 -e MongoDbSettings:Host=mongo -e MongoDbSettings:Password=pass1234 --network=titanic cheloghm/titanic:v26

        And run the database
        ```sh
            $ docker run -d --rm --name mongo -p 27017:27017 -v mongodbdata:/data/db -e MONGO_INITDB_ROOT_USERNAME=mongoadmin -e                MONGO_INITDB_ROOT_PASSWORD=pass1234 --network=titanic cheloghm/mondo:v4

### To run UnitTests
    ```sh
    $ dotnet test 
    ```

To run in a K8s cluster Ensure you create the secret: kubectl create secret generic titanic-secrets --from-literal=mongodb-password='pass1234'

More information on that coming soon.
