Deploy Seata Server By Kubernetes

Last Updated

  • 2022.07.23 适配 Seata 1.5.x 增加控制台默认端口7091；seata-sever 在1.5.x 以下版本读取conf配置更改为yml配置文件。

Quick Start

Create file seata-server.yaml

  1. apiVersion: v1
  2. kind: Service

  54.             - name: console
  55.               containerPort: 7091
  56.               protocol: TCP
  1. $ 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
