Cloud Computing second project. Create, Dockerise, and Deploy an entire cryptometer service 

with Golang, Docker, and Kubernetes. In this

project I build a Golang service with _Fiber_ framework to get crypto market values and cache them into a Redis database.

## How to run?

Run the application without any configs on your local.

```shell

go build -o main

./main

```

Make a copy of config file:

```shell

cp config.example.yml config.yml

```

Update config values:

```yaml

port: 6030

crypto:

  name: "bitcoin"

  value: "usd"

storage:

  host: "cryptometer-redis-cluster:6379"

  password: ""

  timeout: 5

```

## Endpoints

```json

[

  {

    "endpoint": "/api",

    "method": "get",

    "response": [

      {

        "code": "200",

        "body": {

          "name": "bitcoin",

          "value": 98.202

        }

      },

      {

        "code": "500",

        "body": "Error"

      }

    ]

  },

  {

    "endpoint": "/hlz",

    "method": "get",

    "response": [

      {

        "code": "200",

        "body": "OK [time]"

      },

      {

        "code": "500",

        "body": "Error"

      }

    ]

  }

]

```

## Docker

Use the following image:

```shell

docker pull amirhossein21/cryptometer:v0.2

```

Execute on container:

```shell

docker run --network=cryptonet --name cryptometer -d -p 6030:6030 --mount type=bind,source="$(pwd)"/config.yml,target=/app/config.yml amirhossein21/cryptometer:v0.2

```

## Kubernetes

Configmap:

```yaml

apiVersion: v1

kind: ConfigMap

metadata:

  name: cryptometer-configmap

data:

  config.yml:  |+

    port: 6030

    crypto:

      name: "bitcoin"

      value: "usd"

    storage:

      host: "redis-service:6379"

      password: "12345678"

      timeout: 5

```

Deployment:

```yaml

apiVersion: apps/v1

kind: Deployment

metadata:

  name: cryptometer

spec:

  replicas: 2

  selector:

    matchLabels:

      app: cryptometer

  template:

          ports:

            - containerPort: 6030

              name: cryptometer

          resources:

            requests:

              memory: "64Mi"

              cpu: "250m"

            limits:

              memory: "128Mi"

              cpu: "500m"

          volumeMounts:

            - name: config

              mountPath: /app/config.yml

              subPath: config.yml

      volumes:

        - name: config

          configMap:

            name: cryptometer-configmap

```

Service:

```yaml

apiVersion: v1

kind: Service

metadata:

  name: cryptometer

spec:

  selector:

    app: cryptometer

  ports:

    - protocol: TCP

      port: 6030

      targetPort: 6030
