# How to run Fn on Kubernetes
|
||||
|
||||
*Prerequisite 1: working Kubernetes cluster (v1.7+), and a locally configured kubectl.*
|
||||
|
||||
## Quickstart
|
||||
|
||||
### Steps
|
||||
|
||||
1. Deploy Fn to the Kubernetes cluster:
|
||||
|
||||
```bash
|
||||
$ cd docs/operating/kubernetes/
|
||||
$ kubectl create -f fn-service.yaml
|
||||
```
|
||||
|
||||
2. Once the Pods have started, check the service for the load balancer IP:
|
||||
|
||||
```bash
|
||||
$ kubectl -n fn get svc --watch
|
||||
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
||||
fn-mysql-master 10.96.57.185 <none> 3306/TCP 10m
|
||||
fn-redis-master 10.96.127.51 <none> 6379/TCP 10m
|
||||
fn-service 10.96.245.95 <pending> 8080:30768/TCP,80:31921/TCP 10m
|
||||
kubernetes 10.96.0.1 <none> 443/TCP 15d
|
||||
```
|
||||
|
||||
Note that `fn-service` is initially pending on allocating an external IP. The `kubectl get svc --watch` command will update this once an IP has been assigned.
|
||||
|
||||
3. Test the cluster:
|
||||
|
||||
If you are using a Kubernetes setup that can expose a public load balancer, run:
|
||||
|
||||
```bash
|
||||
$ export FN_API_URL=http://$(kubectl -n fn get service/fn-service -o jsonpath='{.status.loadBalancer.ingress[0].ip}:{.spec.ports[?(@.name=="fn-service")].port}')
|
||||
```
|
||||
|
||||
If you are using a Kubernetes setup like minikube, run
|
||||
|
||||
```bash
|
||||
$ export FN_API_URL=$(minikube -n fn service fn-service --url)
|
||||
```
|
||||
|
||||
Now, test by creating a function via curl:
|
||||
|
||||
```bash
|
||||
$ curl -H "Content-Type: application/json" -X POST -d '{ "app": { "name":"myapp" } }' $FN_API_URL/v1/apps
|
||||
{"message":"App successfully created","app":{"name":"myapp","config":null}}
|
||||
|
||||
$ curl -H "Content-Type: application/json" -X POST -d '{ "route": { "type": "sync", "path":"/hello-sync", "image":"fnproject/hello" } }' $FN_API_URL/v1/apps/myapp/routes
|
||||
{"message":"Route successfully created","route":{"app_name":"myapp","path":"/hello-sync","image":"fnproject/hello","memory":128,"headers":{},"type":"sync","format":"default","timeout":30,"idle_timeout":30,"config":{}}}
|
||||
|
||||
$ curl -H "Content-Type: application/json" -X POST -d '{ "name":"Johnny" }' $FN_API_URL/r/myapp/hello-sync
|
||||
Hello Johnny!
|
||||
```
|
||||
|
||||
You can also use the [Fn CLI](https://github.com/fnproject/cli):
|
||||
|
||||
```bash
|
||||
$ export FN_API_URL=http://192.168.99.100:30966
|
||||
$ fn apps list
|
||||
myapp
|
||||
|
||||
$ fn routes list myapp
|
||||
path image endpoint
|
||||
/hello-sync fnproject/hello 192.168.99.100:30966/r/myapp/hello-sync
|
||||
|
||||
$ echo '{"name":"Johnny"}' | fn call myapp /hello-sync
|
||||
Hello Johnny!
|
||||
```
