### Kubernetes
|
|
|
|
There are some yaml files for deploying apisix in Kubernetes.
|
|
|
|
**Note: You can also install Apache APISIX in Kubernetes by [Helm Chart](https://github.com/apache/apisix-helm-chart).**
|
|
|
|
### Prerequisites
|
|
|
|
- use `etcd`, if there is no `etcd` service, please install and set etcd address in `../conf/config.yaml`
|
|
|
|
### Usage
|
|
|
|
#### Create configmap for apache apisix
|
|
|
|
if you do not need to change any config, and use default config in `../conf/config.yaml`
|
|
|
|
```
|
|
$ kubectl create configmap apisix-gw-config.yaml --from-file=../conf/config.yaml
|
|
```
|
|
|
|
#### When using etcd-operator
|
|
|
|
when using etcd-operator, you need to change `apisix-gw-config-cm.yaml`:
|
|
|
|
* add CoreDNS IP into dns_resolver
|
|
|
|
```
|
|
dns_resolver:
|
|
- 10.233.0.3 # default coreDNS cluster ip
|
|
|
|
```
|
|
|
|
* change etcd host
|
|
|
|
Following {your-namespace} should be changed to your namespace, for example `default`.
|
|
> Mention: must use `Full Qualified Domain Name`. Short name `etcd-cluster-client` is not work.
|
|
|
|
```
|
|
etcd:
|
|
host:
|
|
- "http://etcd-cluster-client.{your-namespace}.svc.cluster.local:2379" # multiple etcd address
|
|
```
|
|
|
|
#### Create deployment for apache apisix
|
|
|
|
```
|
|
$ kubectl apply -f deployment.yaml
|
|
```
|
|
|
|
#### Create service for apache apisix
|
|
|
|
```
|
|
$ kubectl apply -f service.yaml
|
|
```
|
|
|
|
#### Scale apache apisix
|
|
|
|
```
|
|
$ kubectl scale deployment apisix-gw-deployment --replicas=4
|
|
```
|
|
|
|
#### Check running status
|
|
|
|
```
|
|
$ kubectl get cm | grep -i apisix
|
|
apisix-gw-config.yaml 1 1d
|
|
|
|
$ kubectl get pod | grep -i apisix
|
|
apisix-gw-deployment-68df7c7578-5pvxb 1/1 Running 0 1d
|
|
apisix-gw-deployment-68df7c7578-kn89l 1/1 Running 0 1d
|

|
|
apisix-gw-deployment-68df7c7578-32ow1 1/1 Running 0 1d
|
|
|
|
$ kubectl get svc | grep -i apisix
|
|
apisix-gw-svc LoadBalancer 172.19.33.28 10.253.0.11 80:31141/TCP,443:30931/TCP 1d
|
|
|
|
```
|
|
|
|
#### Clean up (dangerous)
|
|
|
|
```
|
|
kubectl delete -f .
|
|
```
