使用 Kubernetes 部署 Seata Server

快速启动

创建 seata-server.yaml

apiVersion: v1
kind: Service
metadata:
name: seata-server
namespace: default
labels:
k8s-app: seata-server
spec:
type: NodePort
ports:
- port: 8091
nodePort: 30091
protocol: TCP
name: http
selector:
k8s-app: seata-server

---

apiVersion: apps/v1
kind: Deployment
metadata:
name: seata-server
namespace: default
labels:
k8s-app: seata-server
spec:
replicas: 1
selector:
matchLabels:
k8s-app: seata-server
template:
metadata:
labels:
k8s-app: seata-server
spec:
containers:
- name: seata-server
image: docker.io/seataio/seata-server:latest
imagePullPolicy: IfNotPresent
env:
- name: SEATA_PORT
value: "8091"
- name: STORE_MODE
value: file
ports:
- name: http
containerPort: 8091
protocol: TCP
$ kubectl apply -f seata-server.yaml

自定义配置

环境变量

支持的环境变量和 Docker 相同,可以参考 使用 Docker 部署 Seata Server

使用自定义配置文件

指定配置文件可以通过挂载文件或使用 ConfigMap 的方式实现,挂载后需要通过指定 SEATA_CONFIG_NAME 指定配置文件位置,并且环境变量的值需要以file:开始, 如: file:/root/seata-config/registry
