Docker Compose 运行 Elastic Stack 8.X
材料准备 如题，使用 Docker Compose 运行 Elastic Stack 8.X，五个月前还在前司做 7.9 版本的 ELK 迁移，如今已经是前司了，当时总共不到 20TB，最近问前同事数据量已经到 40TB 了，而且根据她发我的截图来看，三千多个索引，副本分片却只有两千多，不操心了，事不关己高高挂起，反正现在负责 ELK 的是新来的陌生人。今天看已经发到 8.10 版本了，来装一个感受下新特性。 官方 Docker Compose 官方安装指引文档 额外操作参考博客 version: "2.2" services: setup: image: docker.elastic.co/elasticsearch/elasticsearch:${STACK_VERSION} volumes: - certs:/usr/share/elasticsearch/config/certs user: "0" command: > bash -c ' if [ x${ELASTIC_PASSWORD} == x ];
