seata docker部署

 

一. docker拉取seata-server鏡像

docker pull seataio/seata-server:1.1.0

二. docker run方式啓動

docker run --name seata-server -it -d  -p 8091:8091 \
-e SEATA_CONFIG_NAME=file:/root/seata/config/registry \
-e SEATA_IP=192.168.2.248 \
-v /opt/seata/config/:/root/seata/config \
--net=bridge --restart=always docker.io/seataio/seata-server:1.1.0

三. docker compose 啓動

docker-compose.yaml 示例

version: '3'
services:
  seata-server:
    restart: always
    image: seataio/seata-server:1.1.0
    environment:
     - SEATA_IP=192.168.2.225
     - SEATA_CONFIG_NAME=file:/root/seata/config/registry
    deploy:
      replicas: 1
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3
        window: 120s
      resources:
        limits:
          cpus: '0.5'
          memory: 1024M
        reservations:
          cpus: '1'
          memory: 2408M
    volumes:
      - /opt/seata/config/:/root/seata/config
    ports:
      - "8091:8091"
    container_name: "seata-server"
    networks:
      - back-up
networks:
  back-up:
    driver: bridge

docker-compose 啓動

docker-compose -f docker-compose.yaml up -d

四. 容器命令及查看日誌

docker exec -it seata-server sh

docker logs -f seata-server

五. 使用自定義配置文件

自定義配置文件需要通過掛載文件的方式實現，將宿主機上的 registry.conf 和 file.conf 掛載到容器中相應的目錄

• 指定 registry.conf

使用自定義配置文件時必須指定環境變量 SEATA_CONFIG_NAME, 並且值需要以file:開始, 如: file:/root/seata/config/registry

關鍵代碼：

#設置seata配置文件名稱
-e SEATA_CONFIG_NAME=file:/root/seata/config/registry 
#掛外宿主機配置文件目錄
-v /opt/seata/config/:/root/seata/config

其中 -e 用於配置環境變量， -v 用於掛載宿主機的目錄

• 指定 file.conf

如果需要同時指定 file.conf 配置文件，則需要在 registry.conf 文件中將 config 配置改爲以下內容，name 的值爲容器中對應的路徑

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "eureka"

  eureka {
    serviceUrl = "http://admin:[email protected]:19001/eureka/"
    application = "seata-server"
    weight = "1"
  }
  
}

config {
  type = "file"
  file {
    name = "file:/root/seata/config/file.conf"
  }
}

六. 環境變量

seata-server 支持以下環境變量：

• SEATA_IP

可選, 指定seata-server啓動的IP, 該IP用於向註冊中心註冊時使用, 如eureka等

• SEATA_PORT

可選, 指定seata-server啓動的端口, 默認爲 8091

• STORE_MODE

可選, 指定seata-server的事務日誌存儲方式, 支持db 和 file, 默認是 file

• SERVER_NODE

可選, 用於指定seata-server節點ID, 如 1,2,3..., 默認爲 1

• SEATA_ENV

可選, 指定 seata-server 運行環境, 如 dev, test 等, 服務啓動時會使用 registry-dev.conf 這樣的配置

• SEATA_CONFIG_NAME

可選, 指定配置文件位置, 如 file:/root/registry, 將會加載 /root/registry.conf 作爲配置文件，如果需要同時指定 file.conf文件，需要將registry.conf的config.file.name的值改爲類似file:/root/file.conf：

七. 配置文件詳解
