1, the mirror pulling docker elasticsearch
[root@hadoop-keda /]# docker pull elasticsearch:7.4.2
7.4.2: Pulling from library/elasticsearch
2, configure the parameters of the host, or not start, it will error:
max Virtual Memory Areas vm.max_map_count [65530] IS TOO Low, Increase to AT Least [262144]
[root@study-01 ~]# vim /etc/sysctl.conf
vm.max_map_count=655360
[root@study-01 ~]# sysctl -p
3, start concise version of the container
sudo docker run -id \
--net docker-hadoop-net \
--ip 172.170.0.15 \
--restart=always \
--hostname=hadoop_elasticsearch \
--name=hadoop-elasticsearch \
-p 19200:9200 \
-p 19300:9300 \

-e "discovery.type=single-node" \
-e TZ='Asia/Shanghai' \

elasticsearch:7.4.2
4, copy files container, to the host
[root@hadoop-keda software]# docker cp 97d21381af5a4e49e:/usr/share/elasticsearch/config/ /usr/docker/software/elasticsearch/
[root@hadoop-keda software]# docker cp 97d21381af5a4e49e:/usr/share/elasticsearch/data/ /usr/docker/software/elasticsearch/
[root@hadoop-keda software]# docker cp 97d21381af5a4e49e:/usr/share/elasticsearch/logs/ /usr/docker/software/elasticsearch/
[root@hadoop-keda software]# docker cp 97d21381af5a4e49e:/usr/share/elasticsearch/plugins/ /usr/docker/software/elasticsearch/
5, start elasticsearch container
sudo docker run -tid \
--net docker-hadoop-net \
--ip 172.170.0.15 \
--restart=always \
--hostname=hadoop_elasticsearch \
--name=hadoop-elasticsearch \
-p 19200:9200 \

elasticsearch:7.4.2
Note:
-e "SINGLE-Node discovery.type =" represents a single node starts.
If yml file, configuration is a cluster environment, this needs to be removed
6, port open host, and (Ali cloud server, you need to turn through the console port 19200)
7, access the test
8, install IK tokenizer (install plug into the docker container)
[root@hadoop-keda config]# docker exec -it 9e4e12672334 bash
[root@hadoop_elasticsearch elasticsearch]# ls
bin config data jdk lib LICENSE.txt logs modules NOTICE.txt plugins README.textile

9, mounting mobz / elasticsearch-head and connected to the container elasticsearch
[root@hadoop-keda ~]# sudo docker run -dit \
> --net docker-hadoop-net \
> --ip 172.170.0.18 \
> --restart=always \
> --hostname=hadoop_elasticsearch_head \

> -e TZ='Asia/Shanghai' \
> -e LANG="en_US.UTF-8" \
> mobz/elasticsearch-head:5
10, open port of the host, (Ali cloud server, you need to open port 19100 through the console)
