max virtual memory areas vm.max_map_count [65530]

一、故障现象

# 启动ELK容器时报错：
# docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk
[1] bootstrap checks failed

二、解决方法

# sudo sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144

再次运行容器：
启动ELK：

# docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk
