Quick Start

Create file 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: service
    - port: 7091
      nodePort: 30092
      protocol: TCP
      name: console
  selector:
    k8s-app: seata-server

              value: "8091"

              protocol: TCP
            - name: console
              containerPort: 7091
              protocol: TCP

$ kubectl apply -f seata-server.yaml

Custom configuration

Environment

The environment is same with Docker, can reference Deploy Seata Server By Docker

Use specify configuration file

Can specify configuration file by mount files or use ConfigMap, and then need specify environment SEATA_CONFIG_NAME, the value need start with file:, like file:/root/seata-config/registry
