# Kaniko example
2+
3+
This example shows how kaniko can be used instead of docker to build and push an docker image directly inside the cluster.
4+
5+
# Step 0: Prerequisites
6+
7+
In order to use this example, make sure you have a working minikube setup (you don't need an additional docker daemon or docker registry, because devspace can use the internal minikube docker daemon and will deploy a registry for you). See [install minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/) for more details.
8+
9+
# Step 1: Start the devspace
10+
11+
To deploy the application to minikube simply run `devspace up`. The output of the command should look similar to this:
12+
13+
```

[DONE] √ Successfully deployed devspace-default

[DONE] √ Port forwarding started on 8080:8080
67+
[DONE] √ Sync started on /go-workspace/src/github.com/covexo/devspace/examples/kaniko-minikube <-> /app (Pod: test/devspace-default-749f45ddcc-vgp4z)
68+
root@devspace-default-749f45ddcc-vgp4z:/go/src/app#
69+
```
70+
71+
The command created a test namespace, deployed a tiller server and internal registry and used a kaniko build pod to build the dockerfile.
72+
73+
Furthermore a bi-directional sync was started between the local folder `/go-workspace/src/github.com/covexo/devspace/examples/kaniko-minikube` and `/app` within the docker container. Whenever you change a file in either of those two folders the change will be synchronized. In addition the container port 8080 was forwarded to your local port 8080.
74+
75+
# Step 2: Start developing
76+
77+
You can start the server now with `go run main.go` in the open terminal. Now navigate in your browser to `localhost:8080` and you should see the output 'Hello World!'.
78+
79+
Change something in `main.go` and re-run `go run main.go`. Now just refresh your browser and you should see the changes immediately.
