Welcome! This guide will get you up and running with Fission on a
Kubernetes cluster.
           
### Cluster preliminaries

Let's ensure you have the Kubernetes CLI and Helm installed and
ready. If you already have these tools, [skip to the next section](#install-fission).

#### Kubernetes CLI

Ensure you have the Kubernetes CLI.

You can get the Kubernetes CLI for OSX like this:
```
$ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin
```

Or, for Linux:
```
$ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin
```

Ensure you have access to a cluster; use kubectl to check your
Kubernetes version:

```
$ kubectl version
```

We need at least Kubernetes 1.6 (older versions may work, but we don't
test them).

#### Set up helm

Helm is an installer for Kubernetes.  If you already use helm, [skip to
the next section](#install-fission).

First, you'll need the helm CLI:

On __OS X__:
```
$ curl -L https://storage.googleapis.com/kubernetes-helm/helm-v2.6.1-darwin-amd64.tar.gz

$ tar xzf helm-v2.6.1-darwin-amd64.tar.gz

$ mv darwin-amd64/helm /usr/local/bin
```

On __Linux__:
```
$ curl -L https://storage.googleapis.com/kubernetes-helm/helm-v2.6.1-linux-amd64.tar.gz

$ tar xzf helm-v2.6.1-linux-amd64.tar.gz

$ mv linux-amd64/helm /usr/local/bin
```

Next, install the Helm server on your Kubernetes cluster:

```
$ kubectl -n kube-system create sa tiller

$ kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller

$ helm init --service-account tiller
```

(The first two commands are there to make sure that helm is allowed to
install stuff on Kubernetes, in the common case that your cluster has
role-based access control.)


### Install Fission

```
$ helm repo add fission-charts https://fission-charts.github.io

$ helm install --namespace fission fission-all
```

#### Minikube

On minikube, you'll need to pass one additional option to the helm
install command:

```
$ helm repo add fission-charts https://fission-charts.github.io

$ helm install --namespace fission fission-all --set serviceType=NodePort
```


#### Minimal version

The fission-all helm chart installs a full set of services including
the NATS message queue, influxDB for logs, etc. If you want a more
minimal setup, you can install the fission-core chart instead.

### Install Fission CLI

#### Mac OS

Get the CLI binary for Mac:

```
$ curl -Lo fission https://github.com/fission/fission/releases/download/nightly20170705/fission-cli-osx && chmod +x fission && sudo mv fission /usr/local/bin/
```

#### Linux

```
$ curl -Lo fission https://github.com/fission/fission/releases/download/nightly20170705/fission-cli-linux && chmod +x fission && sudo mv fission /usr/local/bin/
```

#### Windows

For Windows, you can use the linux binary on WSL. Or you can download
this windows executable: [fission.exe](https://github.com/fission/fission/releases/download/nightly20170705/fission-cli-windows.exe)

### Set environment vars



### Run an example

Finally, you're ready to use Fission!

```
$ fission env create --name nodejs --image fission/node-env:v0.2.1

$ curl -LO https://raw.githubusercontent.com/fission/fission/master/examples/nodejs/hello.js

$ fission function create --name hello --env nodejs --code hello.js

$ fission route create --method GET --url /hello --function hello

$ curl http://$FISSION_ROUTER/hello
Hello, world!
```
