docker-compose ERROR : bootstrap checks failed | max > virtual memory areas vm. max_map_count [65530] 太低，增加到 > 至少 [262144]

Question

我收到此错误:

es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,267+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "docker-cluster", "node.name": "es01", "message": "starting ..." } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,709+0000", "level": "INFO", "component": "o.e.t.TransportService", "cluster.name": "docker-cluster", "node.name": "es01", "message": "publish_address {172.21.0.3:9300}, bound_addresses {0.0.0.0:9300}" } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,760+0000", "level": "INFO", "component": "o.e.b.BootstrapChecks", "cluster.name": "docker-cluster", "node.name": "es01", "message": "bound or publishing to a non-loopback address, enforcing bootstrap checks" }

重要的错误:

ERROR: [1] bootstrap checks failed es01 | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

然后节点因上述错误而停止:

es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,810+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "docker-cluster", "node.name": "es01", "message": "stopping ..." } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,904+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "docker-cluster", "node.name": "es01", "message": "stopped" } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,905+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "docker-cluster", "node.name": "es01", "message": "closing ..." } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,967+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "docker-cluster", "node.name": "es01", "message": "closed" } es01 | {"type": "server", "timestamp": "2019-09-18T17:31:42,976+0000", "level": "INFO", "component": "o.e.x.m.p.NativeController", "cluster.name": "docker-cluster", "node.name": "es01", "message": "Native controller process has stopped - no new native processes can be started" }

我的 docker-compose.yml 文件如下:

volumes:
  esdata01:
    driver: local
  esdata02:
    driver: local

有谁知道如何增加集群的内存并修复错误？

看起来解决方案是使用:
https://github.com/docker-library/elasticsearch/issues/111

这建议在 ubuntu 上运行它:

sudo sysctl -w vm.max_map_count=262144
