docker elasticsearch Exception in thread "main" java.nio.file.NoSuchFileException: /usr/share/elasti

 

问题

Exception in thread "main" java.nio.file.NoSuchFileException: /usr/share/elasticsearch/config/jvm.options

elasticsearch：7.6.0

docker elasticsearch run遇到两个问题

宿主机映射路径自定义 /web/es/config/ 和/web/es/data/

1）宿主机映射config文件夹权限问题 /usr/share/elasticsearch/config

2）宿主机映射data文件夹权限问题 /usr/share/elasticsearch/data

尝试1 失败 与privileged无关  --user="elasticsearch"无效

docker run --name es --user="elasticsearch" -v /web/es1/config/:/usr/share/elasticsearch/config -v /web/es1/data/:/usr/share/elasticsearch/data -p 9201:9200 -p 9301:9300 -e "discovery.type=single-node" --privileged=true -d elasticsearch:7.6.0

尝试2 查看宿主机映射目录权限及测试运行docker elasticsearch权限【命令 ll -a】

发现外部的权限root:root

容器内

解决

经过百般尝试，最终通过容器内部文件拷贝解决

1、测试单节点es运行

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.0

2、拷贝es容器文件夹config到宿主机目录

docker cp elasticsearch:/usr/share/elasticsearch/config /web/es/

3、再运行完整es命令

docker run --name elasticsearch -v /web/es/config/:/usr/share/elasticsearch/config -v /web/es/data/:/usr/share/elasticsearch/data -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --privileged=true -d elasticsearch:7.6.0
