Welcome! This guide will get you up and running with Fission on a
|
|
Kubernetes cluster.
|
|
|
|
### Cluster preliminaries
|
|
|
|
If you don't have a Kubernetes cluster, [here's a quick guide to set
|
|
one up](../kubernetessetup).
|
|
|
|
Let's ensure you have the Kubernetes CLI and Helm installed and
|
|
ready. If you already have helm, [skip ahead to the fission install](#install-fission).
|
|
|
|
#### Kubernetes CLI
|
|
|
|
Ensure you have the Kubernetes CLI.
|
|
|
|
You can get the Kubernetes CLI for OSX like this:
|
|
```sh
|
|
$ 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:
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
$ kubectl version
|
|
```
|
|
|
|
We need at least Kubernetes 1.6 (older versions may work, but we don't
|
|
test them).
|
|
|
|
#### 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__:
|
|
```sh
|
|
$ curl -LO https://storage.googleapis.com/kubernetes-helm/helm-v2.7.0-darwin-amd64.tar.gz
|
|
|
|
$ tar xzf helm-v2.7.0-darwin-amd64.tar.gz
|
|
|
|
$ mv darwin-amd64/helm /usr/local/bin
|
|
```
|
|
|
|
On __Linux__:
|
|
```sh
|
|
$ curl -LO https://storage.googleapis.com/kubernetes-helm/helm-v2.7.0-linux-amd64.tar.gz
|
|
|
|
$ tar xzf helm-v2.7.0-linux-amd64.tar.gz
|
|
|
|
$ mv linux-amd64/helm /usr/local/bin
|
|
```
|
|
|
|
Next, install the Helm server on your Kubernetes cluster:
|
|
|
|
```sh
|
|
$ helm init
|
|
```
|
|
|
|
### Install Fission
|
|
|
|
#### Minikube
|
|
|
|
```sh
|
|
$ helm install --namespace fission --set serviceType=NodePort https://github.com/fission/fission/releases/download/0.6.0/fission-all-0.6.0.tgz
|
|
```
|
|
|
|
The serviceType variable allows configuring the type of Kubernetes
|
|
service outside the cluster. You can use `ClusterIP` if you don't
|
|
want to expose anything outside the cluster.
|
|
|
|
#### Cloud hosted clusters (GKE, AWS, Azure etc.)
|
|
|
|
```sh
|
|
$ helm install --namespace fission https://github.com/fission/fission/releases/download/0.6.0/fission-all-0.6.0.tgz
|
|
```
|
|
|
|
#### 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:
|
|
|
|
```sh
|
|
$ helm install --namespace fission https://github.com/fission/fission/releases/download/0.6.0/fission-core-0.6.0.tgz
|
|
```
|
|
|
|
### Install the Fission CLI
|
|
|
|
#### OS X
|
|
|
|
Get the CLI binary for Mac:
|
|
|
|
```sh
|
|
$ curl -Lo fission https://github.com/fission/fission/releases/download/0.6.0/fission-cli-osx && chmod +x fission && sudo mv fission /usr/local/bin/
|
|
```
|
|
|
|
#### Linux
|
|
|
|
```sh
|
|
$ curl -Lo fission https://github.com/fission/fission/releases/download/0.6.0/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/0.6.0/fission-cli-windows.exe)
|
|
|
|
### Run an example
|
|
|
|
Finally, you're ready to use Fission!
|
|
|
|
```sh
|
|
$ fission env create --name nodejs --image fission/node-env:0.6.0
|
|
|
|
$ curl -LO https://raw.githubusercontent.com/fission/fission/master/examples/nodejs/hello.js
|
|
|
|
$ fission function create --name hello --env nodejs --code hello.js
|
|
|
|
$ fission function test --name hello
|
|
Hello, world!
|
|
```
|
|
|
|
For a compiled language like Go:
|
|
|
|
```sh
|
|
$ fission env create --name go --image fission/go-env:0.6.0 --builder fission/go-builder:0.6.0
|
|
|
|
$ curl -LO https://raw.githubusercontent.com/fission/fission/master/examples/go/hello.go
|
|
|
|
$ fission function create --name gohello --env go --src hello.go --entrypoint Handler
|
|
|
|
$ fission function test --name gohello
|
|
Hello, world!
|
|
```
|
|
|
|
