#### openIM k8s部署文档
|
|
|
|
|
|
### 1. 修改配置文件
|
|
|
|
|
|
在Open-IM-SERVER目录下修改config/config.yaml配置文件, 将MySQL, Kafka, MongoDB等配置修改。
|
|
|
|
|
|
|
|
|
|
|
|
### 2. 项目根目录创建im configMap到k8s openim namespace
|
|
|
|
|
|
kubectl create namespace openim
|
|
|
|
|
|
kubectl -n openim create configmap config --from-file=config/config.yaml
|
|
|
|
|
|
openim 为im项目的namespace, 可选
|
|
|
|
|
|
查看configmap
|
|
|
|
|
|
kubectl -n openim get configmap
|
|
|
|
|
|
|
|
|
|
|
|
### 3(可选). 修改每个deployment.yml
|
|
|
|
|
|
kubectl get nodes
|
|
|
|
|
|
kubectl label node k8s-node1 role=kube-Node
|
|
|
|
|
|
应需要调度的node打上标签
|
|
|
|
|
|
nodeSelector:
|
|
|
|
|
|
node: kube-Node
|
|
|
|
|
|
创建资源清单时添加上nodeSelector属性对应即可
|
|
|
|
|
|
修改每种服务数量，建议至少每种2个rpc。
|
|
|
|
|
|
如果修改了config/config.yaml某些配置比如端口，同时需要修改对应deployment端口和ingress端口
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 4. 修改ingress.yaml配置文件
|
|
|
|
|
|
需要安装ingress controller 这里使用的是ingress-nginx 其他ingress需要修改配置文件
|
|
|
|
|
|
进行域名修改等操作
|
|
|
|
|
|
|
|
|
|
|
|
### 5. 执行./kubectl_start.sh脚本
|
|
|
|
|
|
chmod +x ./kubectl_start.sh ./kubectl_stop.sh
|
|
|
|
|
|
./kubectl_start.sh
|
|
|
|
|
|
kubectl -n openim apply -f ingress.yaml
|
|
|
|
|
|
kubectl 启动所有deployment，services，ingress
|
|
|
|
|
|
|
|
|
|
|
|
### 6. 查看k8s deployment service ingress状态
|
|
|
|
|
|
kubectl -n openim get services
|
|
|
|
|
|
kubectl -n openim get deployment
|
|
|
|
|
|
kubectl -n openim get ingress
|
|
|
|
|
|
kubectl -n openim get pods
|
