Docker 中部署 Nacos 集群

一、配置一览

1、镜像构建相关文件

1.1 Nacos 配置 PostgreSQL 数据源

Nacos 可以使用内置数据源，内置数据源不需要做任何配置，也可以配置外置数据源，默认的使 MySQL。

生产使用建议至少主备模式，或者采用高可用数据库。

因为从学校出来之后一直用的都是 PostgreSQL，所以 Nacos 这里也使用 PostgreSQL 来作为数据源。

Nacos 从 2.2.0 版本开始，可通过 SPI 机制注入多数据源实现插件，并在引入对应数据源实现后，便可在 Nacos 启动时通过读取 application.properties 配置文件中 spring.datasource.platform 配置项选择加载对应多数据源插件。

在原来的 Config 模块中，所有的 SQL 操作的执行是通过直接使用 JdbcTemplate 执行固定 SQL 语句的形式，使得 SQL 语句与业务逻辑高度耦合，并且只支持 Derby 与 MySQL 两种数据源。

Nacos 数据源插件介绍：nacos datasource plugin

官方提供的插件列表如下：nacos-group/nacos-plugin。

从 GitHub 获取项目之后，将 nacos-postgresql-datasource-plugin-ext 模组打包为 jar 文件之后在构建 Nacos 镜像时使用。

1.2 Nacos 的 startup.sh 文件

#!/bin/bash

export CUSTOM_SEARCH_LOCATIONS=file:${BASE_DIR}/conf/

   if [[ ! -d "${PLUGINS_DIR}" ]]; then
    echo "" >"$CLUSTER_CONF"
    for server in ${NACOS_SERVERS}; do
      echo "$server" >>"$CLUSTER_CONF"
    done
  else
    bash $PLUGINS_DIR/plugin.sh
    sleep 30
  fi
}

echo "Nacos is starting, you can docker logs your container"
exec $JAVA ${JAVA_OPT}

此 shell 文件中需要注意的地方：

• print_servers 方法中清空 CLUSTER_CONF 文件之后，将 NACOS_SERVERS 变量的值追加写入到 CLUSTER_CONF 文件中。
• 添加 Java 启动参数 -Dloader.path，其中有如下片段 ${BASE_DIR}/plugins，plugins 文件夹下即为自定义插件需要添加的位置。

1.3 Nacos 的 application.properties 文件

Nacos 的配置可以通过 properties 文件更改。

此 properties 文件为构建镜像时使用的配置文件。

Dockerfile 文件中添加如下配置，自定义 yum 镜像源，改善网络下载速度。不知道为啥，我开了 VPN，并且也开了 TUN 模式了，还是会下载超时。

2、容器编排相关文件

2.1 .env 文件

image=z2huo/nacos-dev:2.2.3
restart=unless-stopped

2.2 cluster.conf 文件

nacos-1:8848
nacos-2:8848
nacos-3:8848

2.3 nacos-cluster.env 文件

MODE=cluster
PREFER_HOST_MODE=hostname
NACOS_SERVERS=nacos-1:8848 nacos-2:8848 nacos-3:8848
# NACOS_SERVERS=nacos-1:8848 nacos-2:8849 nacos-3:8850

• NACOS_SERVERS 属性，定义集群地址，多个地址之间用空格分隔
• PREFER_HOST_MODE 属性，定义 Nacos 支持 IP 还是域名，取值 hostname 或 ip，默认为 ip。
• MODE 属性，定义系统启动的方式，集群模式还是单机模式，取值 cluster 或 standalone，默认为 cluster。

      # - ./cluster.conf:/home/nacos/conf/cluster.conf
    ports:

      - "8850:8848"
      - "9870:9848"
      - "9852:9849"
    env_file:
      - ./nacos-cluster.env
    restart: ${restart}

Compose 文件中需要注意的配置：

• 在 networks 中定义 postgres-master-slave-net 网络，该网络是 docker 中部署的 PostgreSQL 主从复制所使用的桥接网络，该网络需要配置 external: true 表示使用的是当前 Compose 之外的网络。
• 挂载 application.properties 配置文件，用来替代构建的镜像中的配置文件
• 不用挂载 cluster.conf 文件，因为在 docker-startup.sh 文件中，print_servers 方法中会向 cluster.conf 文件中写入内容。
• 需要暴露 4 个端口
  • 7848，Raft 集群通信端口，用于 Nacos 集群节点之间的 Raft 协议通信。Raft 是 Nacos 默认的集群选举和数据一致性协议，集群节点通过此端口进行 Leader 选举和日志复制。
  • 8848，HTTP API 端口。提供主要的 HTTP API 服务接口，用于客户端与 Nacos 服务端之间的交互。涵盖服务注册、服务发现、配置管理等功能。
  • 9848，服务健康检查端口。提供服务端的健康检查和监控接口。用于获取 Nacos 服务端的运行状态信息（如 CPU 使用率、负载、集群状态等）。
  • 9849，Grpc 通信端口。用于 Nacos 内部服务和客户端之间基于 gRPC 协议的通信。支持更高效的长连接通信，特别是在 Nacos 2.x 中，gRPC 替代了部分 HTTP 通信，成为主要的注册与心跳通信协议。

如果你有很多自定义配置的需求，强烈建议在生产环境对 application.properties 文件进行挂卷定义.

2.5 application.properties 配置文件

2.5.1 数据库配置

### If use MySQL as datasource:
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.
# spring.datasource.platform=mysql
spring.sql.init.platform=postgresql

### Connect URL of DB:
db.url.0=jdbc:postgresql://postgres-master:5432/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai
db.user.0=*****
db.password.0=*****

### Connection pool configuration: hikariCP
db.pool.config.connectionTimeout=30000
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2
db.pool.config.driverClassName=org.postgresql.Driver
db.pool.config.connectionTestQuery=SELECT 1

2.5.2 鉴权配置

二、部署过程

1、打包 Nacos PostgreSQL 数据源插件

从官方提供的插件列表 nacos-group/nacos-plugin 中下载 PostgreSQL 插件。用 IDEA 打开，构建项目并打包。

将打包好的 jar 包添加到 Dockerfile 文件中：

ADD plugins/nacos-postgresql-datasource-plugin-ext-1.0.0-SNAPSHOT.jar plugins/nacos-postgresql-datasource-plugin-ext-1.0.0-SNAPSHOT.jar

2、在 PostgreSQL 中创建数据库

在 PostgreSQL 中创建 Nacos 使用的数据库，并执行 DDL 建表语句。

3、构建 Nacos 镜像

构建 Nacos 镜像。

docker build -t z2huo/nacos-dev:2.2.3 .

4、启动服务

$ docker compose config
$ docker compose up -d

查看容器日志，可以看到日志中的集群地址：The server IP list of Nacos is [nacos-1:8848, nacos-2:8848, nacos-3:8848]

2025-01-16 22:33:43 

浏览器中访问 Nacos 地址，查看集群节点：

三、其他

1、构建 Nacos 镜像时基础镜像的选择

没有使用最新的 Nacos 发行版，使用的 2.2.3 版本。Nacos 默认支持内置数据源和 MySQL 数据源，而我的数据源选择的是 PostgreSQL，需要用到数据源扩展插件 nacos-plugin/nacos-datasource-plugin-ext，该插件暂时只支持 Nacos 2.2.x 版本，防止因为版本不适配问题，Nacos 选择 2.2.3 版本。

在 2.2.3 版本中，参考的 nacos-group/nacos-docker 项目中使用的是 centos 镜像作为基础镜像，而该镜像大小为 300 MB，在最新的 Nacos 发行版中，使用的是 alpine 镜像，该镜像只有 8 MB。

所以最后构建出来的 Nacos 镜像，大小有 800 MB。啊，这个，这个有点太大了。但是，就这样吧。以后再做尝试。

2、Nacos PostgreSQL DDL

DROP TABLE IF EXISTS "config_info";  
CREATE TABLE "config_info" (  
  "id" bigserial NOT NULL,  
  "data_id" varchar(255)  NOT NULL,  
  "group_id" varchar(255) ,  
  "content" text  NOT NULL,  
  "md5" varchar(32) ,  
  "gmt_create" timestamp(6) NOT NULL,  
  "gmt_modified" timestamp(6) NOT NULL,  
  "src_user" text ,

3、构建 Nacos 2.2.3 版本 alpine 镜像

开始使用的是 Nacos Group 提供的 Dockerfile，里面 2.2.3 版本镜像构建使用的是 centos，这导致了最终的 Nacos 镜像有 800 MB。太大了，而且构建过程很慢，可能也是我网络的问题，是不是还会有的工具包下载失败。

现在替换为 alpine 镜像，只需在 Dockerfile 中做如下修改即可：

# 基于 alpine 镜像
FROM alpine:latest

# 安装依赖
RUN apk add --no-cache openjdk8-jre-base curl iputils ncurses vim libcurl bash

ENTRYPOINT ["bash", "bin/docker-startup.sh"]

需要将 Nacos 镜像的基础镜像改为 alpine，并且需要使用 alpine 中的包管理工具 apk 下载需要使用到的软件包。

之后运行构建镜像命令。

$ docker build -f 2.2.3-alpine.dockerfile -t z2huo/nacos-dev:2.2.3-alpine .
$ docker build -f 2.2.3-centos.dockerfile -t z2huo/nacos-dev:2.2.3-centos .

3.1 注意事项

3.1.1 CRLF 问题

Shell 脚本是跟 markdown 一起存放在 Git 中的，并且 Git 配置了 git config --global core.autocrlf true 用来自动在 LF 和 CRLF 两者之间转换（因为也在 MacOS 上面，MacOS 上面默认为 LF）。docker-startup.sh 文件构建到镜像中，是需要在 Linux 中执行的，Linux 中也是 LF，所以要检查文档的换行是否为 LF。

没有检查，在启动容器时执行 docker-startup.sh 脚本时报错：

nacos-1  | bin/docker-startup.sh: line 6: $'\r': command not found

说明 Shell 脚本中有 CR 存在。

3.1.2 ENTRYPOINT 指定容器启动时默认执行的命令

nacos-group/nacos-docker 项目的 2.2.3 分支版本的 Dockerfile 中有如下片段：

ENTRYPOINT ["bin/docker-startup.sh"]

之写了需要执行的 Shell 文件，但是没有写需要使用 sh 还是 bash，像这样 ENTRYPOINT ["sh", "bin/docker-startup.sh"]。最开始构建镜像时可以成功启动容器，但是后来尝试使用 alpine 时，重新构建了 centos 镜像，发现原来没有加也不行了，启动容器时报错如下：

exec bin/docker-startup.sh: no such file or directory

所以将 Dockerfile 中修改为：

ENTRYPOINT ["bash", "bin/docker-startup.sh"]

3.1.3 选择执行 docker-startup.sh 的 Shell

docker-startup.sh 中有 set -x，这个是在 sh 中是不支持的，在 bash 中有支持。

nacos-group/nacos-docker 项目中使用 alpine 的 Dockerfile 中，需要额外安装 bash，centos 应该是自带的吧（猜测）。

RUN apk add --no-cache openjdk8-jre-base curl iputils ncurses vim libcurl bash

如果 ENTRYPOINT ["sh", "bin/docker-startup.sh"] 中使用 sh 执行 docker-startup.sh，会报错如下：

2025-01-17 13:34:38 bin/docker-startup.sh: line 6:
: not found
2025-01-17 13:34:38 bin/docker-startup.sh: set: line 14: illegal option -

不支持的命令或语法，另外还会 for 循环什么的也会报错。

所以应该这样 ENTRYPOINT ["bash", "bin/docker-startup.sh"]，使用 bash 执行 docker-startup.sh。
