本篇概览

前文《Docker下elasticsearch8部署、扩容、基本操作实战(含kibana)》介绍了用docker快速部署es和kibana的过程，然而整个过程人工操作步骤还是多了点，能不能更简单些呢？毕竟很多时候大家关注的是使用，不愿在部署上费太多时间
借助docker-compose，可以将es集群+kibana的安装过程可以进一步简化，精简后的步骤如下图，已经省的不能再省了...
本文会按照上述流程进行实战，一共实战两次：第一次部署带证书账号密码的安全版本，第二次部署没有任何安全检查的版本，装好直接访问使用
请注意docker部署ElasticSearch的适用场景：我这边只在开发过程中使用，此种方式在生产环境是否适合是有待商榷的，用于生产环境时请您慎重考虑
本篇由以下内容构成

介绍我这边实战的环境供您参考
Linxu用户需要额外注意的地方
编写配置文件
启动
验证

环境信息

以下是本次实战的环境信息，可以作为参考

操作系统：macOS Monterey（M1 Pro芯片的MacBook Pro，16G内存）
Docker：Docker Desktop 4.7.1 (77678)
ElasticSearch：8.2.2
Kibana：8.2.2

Linux用户请注意

如果您的环境是Linux，注意要做以下操作，否则es可能会启动失败

用编辑工具打开文件/etc/sysctl.conf
在尾部添加一行配置vm.max_map_count = 262144，如果已存在就修改，数值不能低于262144
修改保存，然后执行命令sudo sysctl -p使其立即生效

编写配置文件

再次确认接下来工作的目标：用docker-compose快速部署es集群+kibana，这个集群是带安全检查的（自签证书+账号密码）
找个干净目录，新建名为.env的文件，内容如下，这是给docker-compose用到的配置文件每个配置项都有详细注释说明

# elastic账号的密码 (至少六个字符)
ELASTIC_PASSWORD=123456

# kibana_system账号的密码 (至少六个字符)，该账号仅用于一些kibana的内部设置，不能用来查询es
KIBANA_PASSWORD=abcdef

# es和kibana的版本
STACK_VERSION=8.2.2

# 集群名字
CLUSTER_NAME=docker-cluster

# x-pack安全设置，这里选择basic，基础设置，如果选择了trail，则会在30天后到期
LICENSE=basic
#LICENSE=trial

# es映射到宿主机的的端口
ES_PORT=9200

# kibana映射到宿主机的的端口
KIBANA_PORT=5601

# es容器的内存大小，请根据自己硬件情况调整
MEM_LIMIT=1073741824

# 命名空间，会体现在容器名的前缀上
COMPOSE_PROJECT_NAME=demo

然后是docker-compose.yaml文件，这里面会用到刚才创建的.env文件，一共创建了五个容器：启动操作、三个es组成集群，一个kibana（多说一句：官方脚本，放心用）

          exit 1;
        elif [ x${KIBANA_PASSWORD} == x ]; then
          echo "Set the KIBANA_PASSWORD environment variable in the .env file";
          exit 1;

注意：.env和docker-compose.yaml两个文件在同一目录下

启动应用

在docker-compose.yaml文件所在目录，执行命令docker-compose up -d启动所有容器

看看demo_setup_1的日志，提示启动顺利

❯ docker logs demo_setup_1
Setting file permissions

如果要使用curl命令向ES发请求，需要提前将crt文件从容器中复制出来

docker cp demo_es01_1:/usr/share/elasticsearch/config/certs/es01/es01.crt .

验证

现在来验证es集群和kibana能不能正常工作
浏览器访问https://localhost:9200/，注意是https，会看到以下警告页面
此时直接键入thisisunsafe再回车，会提示输入账号密码，根据之前的配置账号elastic，密码123456

浏览器显示如下，证明es成功响应了
如果chrome上安装了eshead插件，此时就能查看es集群情况了(注意内部的地址栏中，要用https，而非http)，如下图，一共三个节点，es02前面有五角星标志，表示其主节点的身份
目前看来es集群部署和运行都已经正常，再看kibana是否可用
访问http://localhost:5601/，账号elastic，密码123456
点击下图红框位置，进入输入命令的页面
如下图，左侧输入创建索引的命令，再点击红框中的按钮，右侧会显示执行结果
批量写入两条记录
最后是查询操作

清理

如果要删除es，执行docker-compose down就会删除容器，但是，此命令不会删除数据，下次执行docker-compose up -d后，新的es集群中会出现刚才创建的test001索引，并且数据也在
这是因为docker-compose.yaml中使用了数据卷volume存储es集群的关键数据，这些输入被保存在宿主机的磁盘上

❯ docker volume ls
DRIVER    VOLUME NAME
local     demo_certs
local     demo_esdata01
local     demo_esdata02
local     demo_esdata03
local     demo_kibanadata

执行docker volume rm demo_certs demo_esdata01 demo_esdata02 demo_esdata03即可将它们彻底清除
以上就是快速部署es集群+kibana的整个过程了，是不是很简单呢？

不带密码的集群

有时候咱们部署es不需要安全认证，例如开发环境，或者有防火墙禁止外部访问的环境，那么刚才的部署就不够用了，咱们需要一个更简单的、部署完了立刻能用的集群，接下来动手试试吧
找个干净目录，新建名为.env的文件，内容如下，和安全版相比去掉了一些不需要的内容

# kibana_system账号的密码 (至少六个字符)，该账号仅用于一些kibana的内部设置，不能用来查询es
KIBANA_PASSWORD=abcdef

# es和kibana的版本
STACK_VERSION=8.2.2

# 集群名字
CLUSTER_NAME=docker-cluster

# es映射到宿主机的的端口
ES_PORT=9200

# kibana映射到宿主机的的端口
KIBANA_PORT=5601

# es容器的内存大小，请根据自己硬件情况调整
MEM_LIMIT=1073741824

# 命名空间，会体现在容器名的前缀上
COMPOSE_PROJECT_NAME=demo

然后是docker-compose.yaml文件，这里面会用到刚才创建的.env文件，和安全版相比去掉了启动容器，和安全相关的配置和脚本也删除了

在docker-compose.yaml文件所在目录，执行命令docker-compose up -d启动所有容器，稍等片刻，可见所有容器已经就绪

❯ docker ps -a
CONTAINER ID   IMAGE                 COMMAND                  CREATED         STATUS         PORTS                              NAMES

浏览器访问http://localhost:9200/ ，注意是http，收到es响应
chrome的eshead插件也能正常获取es集群信息
访问kibana，地址是http://localhost:5601/ ，注意是http，能够正常使用，下图是成功创建索引的操作
至此，基于docker-compose部署es集群+kibana的部署已经完成，借助娴熟的复制粘贴操作，快速部署一个es集群简直易如反掌，如果您正要快速部署一套es集群，希望本文能给您一些参考
