#!/bin/bash
|
||
err=0
|
||
for k in $(seq 1 2)
|
||
do
|
||
check_code=$(pgrep haproxy)
|
||
if [[ $check_code == "" ]]; then
|
||
err=$(expr $err + 1)
|
||
sleep 1
|
||
continue
|
||
else
|
||
err=0
|
||
break
|
||
fi
|
||
done
|
||
|
||
if [[ $err != "0" ]]; then
|
||
echo "systemctl stop keepalived"
|
||
/usr/bin/systemctl stop keepalived
|
||
exit 1
|
||
else
|
||
exit 0
|
||
fi
|
||
EOF
|
||
|
||
[root@xingdiancloud-native-master-a ~]# chmod +x /etc/keepalived/check_apiserver.sh

##### 9.5 网络组件部署 Calico
|
||
|
||
注意：
|
||
|
||
在calico的官网进行下载对应的yaml文件，在我们master节点上创建
|
||
|
||
下载地址：https://docs.tigera.io/calico/latest/about
|
||
|
||
选择calico v3.26版本
|
||
|
||
```shell
|
||
#把对应命令复制过来,不需要执行
|
||
kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/tigera-operator.yaml
|
||
kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/custom-resources.yaml
|
||
|
||
|
||
#先使用wget下载后，检查文件正常后在进行部署
|
||
[root@xingdiancloud-native-master-a k8s-work]# wget https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/tigera-operator.yaml
|
||
[root@xingdiancloud-native-master-a k8s-work]# wget https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/custom-resources.yaml
|
||
|
||
|
||
[root@xingdiancloud-native-master-a k8s-work]# ll *yaml
|
||
-rw-r--r-- 1 root root 824 Jan 5 13:50 custom-resources.yaml
|
||
-rw-r--r-- 1 root root 1475581 Jan 5 13:50 tigera-operator.yaml
|
||
```
|
||
|
||
###### 9.5.1 修改文件
|
||
|
||
```shell
|
||
#custom-resources.yaml文件默认的pod网络为192.168.0.0/16，我们定义的pod网络为10.244.0.0/16,需要修改后再执行
|
||
cidr: 192.168.0.0/16 修改成 cidr: 10.244.0.0/16
|
||
```
|
||
|
||
注意：
|
||
|
||
Docker-Hub在中国大陆访问被隔断
|
||
|
||
Calico中所有的镜像都需要从Docker-Hub下载
|
||
|
||
执行之前需要事先准备好所需要的镜像，并导入到各个worker节点
|
||
|
||

## 六：部署应用验证
|
||
|
||
#### 1.创建Nginx应用
|
||
|
||
```yaml
|
||
apiVersion: v1
|
||
kind: Namespace
|
||
metadata:
|
||
name: xaddt
|
||
|
||
---
|
||
apiVersion: apps/v1
|
||
kind: Deployment
|
||
metadata:
|
||
name: nginx-xingdian
|
||
labels:
|
||
xingdian: nginx
|
||
namespace: xaddt
|
||
|
||
spec:
|
||
replicas: 2
|
||
selector:
|
||
matchLabels:
|
||
xingdian: nginx
|
||
template:
|
||
metadata:
|
||
labels:
|
||
xingdian: nginx
|
||
spec:
|
||
containers:
|
||
- name: nginx-xingdian
|
||
image: 10.9.12.201/xingdian/nginx:v1
|
||
ports:
|
||
- containerPort: 80
|
||
|
||
---
|
||
apiVersion: v1
|
||
kind: Service
|
||
metadata:
|
||
name: my-xaddt
|
||
namespace: xaddt
|
||
spec:
|
||
selector:
|
||
xingdian: nginx
|
||
type: NodePort
|
||
ports:
|
||
- port: 80
|
||
targetPort: 80
|
||
nodePort: 30011
|
||
```
|
||
|
||
#### 2.执行
|
||
|
||
```shell
|
||
[root@xingdiancloud-native-master-a ~]# kubectl create -f nginx-deployment.yaml
|
||
namespace/xaddt created
|
||
deployment.apps/nginx-xingdian created
|
||
service/my-xaddt created
|
||
```
|
||
|
||
