c、安装说明（K8s）

在K8s平台内部署 canal-server 与 直接使用 Docker 方式部署 canal-server 有所不同；

编写 K8s 服务部署脚本

在服务器根目录下，创建 canal-server-single.yaml 文件，文件内容为：

使用 kubectl 执行如下命令部署 canal-server 服务 ：

# 示例
# kubectl apply -f canal-server.yaml --namespace=你的命名空间
# 将 canal-server 部署到 k8s-ops-prod 空间下
kubectl apply -f canal-server-single.yaml --namespace=ops-prod
