背景

鉴于网上大部分是6 或者7的教程，有点老旧，使用最新版8.0.1。

因为在安装中遇到一点配置问题，遂去查阅文档，并且这部分网上比较少，所以记录一下，方便后面的同学学习使用elasticsearch最新版给个参照。

本机环境

# elasticsearch kibana 2个版本要一一对应
➜  conf docker images 
REPOSITORY      TAG       IMAGE ID       CREATED       SIZE
elasticsearch   8.0.1     a19fb2049f96   13 days ago   652MB
kibana          8.0.1     9fab8ca82613   13 days ago   953MB

安装

步骤一：创建elastic网络

docker network create elastic

步骤二：docker run 并指定网络 elastic 不然后续没法通信

# -e ES_JAVA_OPTS="-Xms512m -Xmx512m"  如果是在测试阶段 建议加上这个配置，不然可能会老是断掉

docker run --name es-node01 --net elastic -p 9200:9200 -p 9300:9300 -t elasticsearch:8.0.1

注意：

步骤二会产生一个token，用于步骤三的登陆
token 有效期是半个小时

-> Configure other nodes to join this cluster:
* Copy the following enrollment token and start new Elasticsearch nodes with `bin/elasticsearch --enrollment-token <token>` (valid for the next 30 minutes):

  If you're running in Docker, copy the enrollment token and run:
  `docker run -e "ENROLLMENT_TOKEN=<token>" docker.elastic.co/elasticsearch/elasticsearch:8.0.1`

如果token过期，或者清屏了，可以用如下命令生成新的token

➜  ~ docker ps
CONTAINER ID   IMAGE                 COMMAND                  CREATED          STATUS          PORTS                                            NAMES
14bdcb85f7e9   elasticsearch:8.0.1   "/bin/tini -- /usr/l…"   10 minutes ago   Up 10 minutes   0.0.0.0:9500->9200/tcp, 0.0.0.0:9600->9300/tcp   es-node01

# 进入 elasticsearch 镜像 
➜  ~ docker exec -it 14bdcb85f7e9  /bin/bash

# 用 elasticsearch-create-enrollment-token 生成新token
elasticsearch@14bdcb85f7e9:~$ bin/elasticsearch-create-enrollment-token --scope kibana

步骤三指定网络 elastic 不然后续没法通信

docker run --name kib-01 --net elastic -p 5601:5601 kibana:8.0.1

打开http://0.0.0.0:5601/?code=414780 是不是很激动，然而配置刚开始，填入步骤二的token

注意：如果这里停在Completing setup，并转圈很久的话，应该是刚刚elasticsearch改token导致elasticsearch停止了，这里启动下elasticsearch就好，问题不大。

➜  conf docker start 14bdcb85f7e9
14bdcb85f7e9

结果

 ~ docker ps
CONTAINER ID   IMAGE                 COMMAND                  CREATED          STATUS          PORTS                                            NAMES
6b55c628936c   kibana:8.0.1          "/bin/tini -- /usr/l…"   21 minutes ago   Up 21 minutes   0.0.0.0:5601->5601/tcp                           kib-01
14bdcb85f7e9   elasticsearch:8.0.1   "/bin/tini -- /usr/l…"   33 minutes ago   Up 16 minutes   0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp   es-node01

bin/elasticsearch-create-enrollment-token --scope kibana

➜  flink docker start 14bdcb85f7e9
14bdcb85f7e9

步骤四设置账号密码

看到账号密码是不是很慌，之前没有设置这个,查阅文档

➜  ~ docker exec -it 91197a2a35cc  /bin/bash
elasticsearch@91197a2a35cc:~$ bin/elasticsearch-reset-password -u elastic
This tool will reset the password of the [elastic] user to an autogenerated value.
The password will be printed in the console.
Please confirm that you would like to continue [y/N]y


Password for the [elastic] user successfully reset.
New value: edBcP-3ciGogXaQ_IXtd
elasticsearch@91197a2a35cc:~$
