解决Docker启动Elasticsearch7.x报错的问题（elasticsearch docker部署）

使用Docker run 命令

docker run -d -p 9200:9200 -p 9300:9300 --name 用户自定义名字 容器ID

会看到一串字符串，一般情况下我们会误以为它启动成功

我们执行docker ps -a是发现它自动退出了

使用docker logs -f 容器ID 查看日志发现：

ERROR: [1] bootstrap checks failed [1]: max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] [2]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

错误提示

告诉我们是ES需要jvm内存太大了，所有我们需要改一下配置，执行下面代码

sysctl -w vm.max_map_count=262144

然后输入下列命令运行一下：

docker run -d -e ES_JAVA_POTS="-Xms256m -Xmx256m" -p 9200:9200 -p 9300:9300 --name ES3 8f46db60ddd6

查看日志发现还是报错：

ERROR: [1] bootstrap checks failed [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

解决方法如下：

docker run -d -e ES_JAVA_POTS="-Xms256m -Xmx256m" -e "discovery.type=single-node" -p 9200:9200 -p :9300 --name ES3 8f46db60ddd6

最终就启动成功了！

补充知识：docker安装elasticsearch 6.4.3 停止

先打印日志

感觉应该是jvm参数配置有问题

先

[root@iZ2ze9gna8ev4h0rme8ph0Z ~]# sudo sysctl -w vm.max_map_count=262144

再

docker run -d -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -e -Des.scripting.exception_for_missing_value=true --name elasticsearch docker.io/elasticsearch:6.4.3

即可解决！
