# 2. Share What You Know 

and model your I/O
</section>
<section id='dry-run' data-markdown>
### Share What You Know `--dry-run`

Generate kubernetes `deployment` and `service` specifications, both named `metrics-review`:

```bash
kubectl run metrics-review --image=quay.io/ryanj/metrics-k8s \
--expose --port=2015 --service-overrides='{ "spec": { "type": "NodePort" } }' \
--dry-run -o yaml > metrics-review.yaml
```
</section>

<section data-markdown id='dry-run'>
### Share What You Know `--dry-run`
  
Test your generated spec:
```bash
kubectl create -f metrics-review.yaml
```

Minikube users will be able to open the resulting service in their browser by running:
```bash
minikube service metrics-review
```
</section>

<section data-markdown id='i-o'>
## Model Your I/O
</section>

<section data-markdown id='example'>
### Example Repo

Create a local clone of this `metrics-k8s` repo:
```bash
git clone http://github.com/ryanj/metrics-k8s
```
</section>

<section data-markdown id='minikube-mount'>
### Preview - local files

Next, share your local repo contents with minikube:
```bash
cd metrics-k8s
minikube mount $(pwd):/var/www/html
```
</section>

<section data-markdown id='hostpath'>
### Preview - hostPath
  
Then, produce a new deployment spec that includes (minimal) support for live development workflows:
  
  1. `cp metrics-review.yaml metrics-dev.yaml`
  2. replace `metrics-review` with `metrics-dev` (global)
  2. Add a `hostPort` volume to access your local repo:
  
```diff
      spec:
        containers:
        - image: quay.io/ryanj/metrics-k8s
          name: metrics-dev
          ports:
          - containerPort: 2015
          resources: {}
+         volumeMounts:
+         - mountPath: /var/www/html
+           name: metrics-src
+       volumes:
+       - name: metrics-src
+         hostPath:
+           path: /var/www/html
  status: {}
```
</section>
  
<section data-markdown id='kubectl-create'>
### Share what you know
  
The resulting file should look just like the included [metrics-dev.yaml](https://raw.githubusercontent.com/ryanj/metrics-k8s/master/metrics-dev.yaml) file from the `metrics-k8s` git repo.

Try launching it with:
```bash
kubectl create -f metrics-dev.yaml
```
</section>

<section data-markdown id='rollout-test'>
### Share what you know - Rollout Testing

Eval this
```bash
minikube docker-env
```

to send newly-built images to minikube's docker daemon:
```bash
docker build .
```

Bugs are more expesive to fix when discovered later

![https://www.whitesourcesoftware.com/wp-content/uploads/2015/10/graph2.jpg](cost of development)

Making the entire pipeline reproducible allows integration bugs to be found during local dev, lowering overall development costs, increasing velocity
