Elasticsearch + Docker：实现容器化部署指南

news2025/3/28 6:37:50

Elasticsearch是一款强大的分布式搜索和分析引擎，广泛应用于日志分析、全文检索、实时数据分析等场景。而Docker作为一种轻量级的容器化技术，能够帮助开发者快速部署和管理应用。将Elasticsearch与Docker结合，不仅可以简化部署流程，还能提高资源利用率和系统可维护性。

1 环境准备

1.1 安装Docker

安装操作请参考：Docker入门指南：1分钟搞定安装 + 常用命令，轻松入门容器化！-CSDN博客

1.2 配置镜像地址

vim /etc/docker/daemon.json 
# 编辑/etc/docker/daemon.json文件，添加如下内容
{
        "registry-mirrors": [
                "https://proxy.1panel.live",
                "https://docker.1panel.top",
                "https://docker.1ms.run",
                "https://docker.ketches.cn",
                "https://docker.hpcloud.cloud",
                "https://docker.1panel.live",
                "http://mirrors.ustc.edu.cn",
                "http://mirror.azure.cn",
                "https://nrbewqda.mirror.aliyuncs.com",
                "https://dmmxhzvq.mirror.aliyuncs.com"
        ]
}

# 重新加载配置并重启docker
systemctl daemon-reload
systemctl restart docker.service

# 验证镜像地址是否生效可用，能够看到Registry Mirrors:说明正常

2 Docker部署安装

2.1 拉取镜像

# 配置镜像地无法拉取，我们直接使用如下命令从Docker Hub进行拉取
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0

[root@node3 ~]# docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0
