项目搭建过程

欢迎关注我的主页Leebai's Blogs

前提条件：本地Windows主机下已经安装了Docker

下载地址： 到Docker主页去找

创建项目

• 项目名称：etcd-practice
• 项目root目录：etcd-practice/

创建ectd的Docker构建配置文件

• 项目root目录下创建etcd目录，etcd目录创建Dockerfile文件，内容如下:

  FROM bitnami/etcd 
  
  LABEL maintainer="Leebai <[email protected]>"

  FROM 指定容器的来源
• 项目root目录下创建etcd-manage目录，etcd-manage目录创建Dockerfile文件，内容如下：

  FROM evildecay/etcdkeeper
  
  LABEL maintainer="Leebai <[email protected]>"

  evildecay/etcdkeeper是一款轻量级的etcd web客户端，详细内容参见evildecay/etcdkeeper-Lightweight etcd web client.

项目根目录配置文件创建

• .env文件,内容如下

# 设置时区
TZ=Asia/Shanghai
# 设置Docker工作的网络模式
NETWORKS_DRIVER=bridge

# 设置本地的etcd的访问端口
ETCD_PORT=2379
# 设备本地的etcd-manage的访问端口
ETCD_MANAGE_PORT=8080

• docker-compose.yaml,内容如下

version: '3.5'
# 网络配置
networks:
  backend:
    driver: ${NETWORKS_DRIVER}

# 服务容器配置
services:
  etcd:                                  # 自定义容器名称
    build:
      context: ./etcd                    # 指定构建使用的 Dockerfile 文件
    environment:
      - TZ=${TZ}
      - ALLOW_NONE_AUTHENTICATION=yes
      - ETCD_ADVERTISE_CLIENT_URLS=http://etcd:2379
    ports:                              
      - "${ETCD_PORT}:2379"          # 设置本地的端口ETCD_PORT映射到容器的2379端口
    networks:
      - backend
    restart: always

  etcd-manage:
    build:
      context: ./etcd-manage
    environment:
      - TZ=${TZ}
    ports:
      - "${ETCD_MANAGE_PORT}:8080"                    # 设置本地的端口ETCD_MANAGE_PORT映射到容器的8080端口
    depends_on:                                       # 依赖容器
      - etcd                                          # 在 etcd 服务容器启动后启动
    networks:
      - backend
    restart: always

cmd进入项目根目录,运行docker-compose up -d构建项目

如果是第一次运行该命令，该命令会先创建镜像，然后启动镜像。具体的运行效果如下所示：

D:\etcd-v3.5.5-windows-amd64\etcd-practice>

打开Windows主机中的Docker Desktop,会发现Images下出现了：

• etcd-practice-etcd
• etcd-practice-etcd-manage

同时Containers下出现了etcd-practice,状态为：Running 这说明在本地已经将项目etcd-practice构建到我们的Docker容器中了。 本地浏览器访问：http://127.0.0.1:8080/是可以访问到我们之前在docker-compose.yaml文件配置的evildecay/etcdkeeper客户端的。
