# Play with dapr in three steps

dapr is new and cool, all you have to do is to follow few steps to play with it.

## Step 1 - Install dapr in your kubernetes cluster

There are few installation approaches to install dapr according to the [official docs](https://docs.dapr.io/getting-started/install-dapr-cli/), for me, I prefer start from the source code which is the original taste and flavour.

```bash
# for those developers outside of China
git clone https://github.com/dapr/dapr.git

# for those developers inside of China
git clone https://gitee.com/dapr-io/dapr.git

# change dir
cd dapr

# install with helm
helm install dapr charts/dapr --namespace dapr-system --create-namespace --wait
NAME: dapr
LAST DEPLOYED: Wed May 19 15:23:17 2021
NAMESPACE: dapr-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Thank you for installing Dapr: High-performance, lightweight serverless runtime for cloud and edge

Your release is named dapr.

To get started with Dapr, we recommend using our quickstarts:
https://github.com/dapr/quickstarts

For more information on running Dapr, visit:
https://dapr.io
```

then, check if dapr is running.

```bash
k -n dapr-system get po 
NAME                                    READY   STATUS    RESTARTS   AGE
dapr-dashboard-564485bbb7-f482n         1/1     Running   0          22m
dapr-operator-7f6d6cd94d-fx24w          1/1     Running   0          22m
dapr-placement-server-0                 1/1     Running   0          22m
dapr-sentry-86dc6d67f-tqjl5             1/1     Running   0          22m
dapr-sidecar-injector-584c69d8f-n9bh7   1/1     Running   0          22m
```

## Step 2 - Deploy apps to be tested with dapr

Install dapr command line client

```bash
# for those developers outside of China
git clone https://github.com/dapr/cli.git

# for those developers inside of China
git clone git@gitee.com:dapr-io/cli.git

# swich dir
cd cli

# build the cli
make build

```

Let's check the dapr status 

```bash

dapr status -k

  NAME                   NAMESPACE    HEALTHY  STATUS   REPLICAS  VERSION  AGE  CREATED

  dapr-operator          dapr-system  True     Running  1         1.1.2    41m  2021-05-19 15:23.18  
  dapr-sidecar-injector  dapr-system  True     Running  1         1.1.2    41m  2021-05-19 15:23.18  
  dapr-sentry            dapr-system  True     Running  1         1.1.2    41m  2021-05-19 15:23.18  
  dapr-dashboard         dapr-system  True     Running  1         0.6.0    41m  2021-05-19 15:23.18  
 
```

check service

```bash
kubectl get svc

```

```bash
curl https://172.19.251.6/ports
```

```json
{
"DAPR_HTTP_PORT": "3500",
"DAPR_GRPC_PORT": "50001"
}
```

## Step 3 - Test

```bash
curl --request POST --data "{\"data\": { \"orderId\": \"42\" } }" --header "Content-Type:application/json" http://172.19.251.6/neworder

curl http://172.19.251.6/order       
```

```json
{
  "orderId": 1230
}
```
