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!
|
|
```
|
|
