一、数据卷挂载权限问题
这是原始docker-compose.yaml文件
version: 3.8networks:my-net:name: gkynetservices:minio:image: bitnami/minio:latestcontainer_name: minioports:- 9000:9000- 9001:9001environment:- MINIO_ROOT_USERroot- MINIO_ROOT_PASSWORD123456volumes:- ./minio/data:/bitnami/minio/datanetworks:- my-netelasticsearch:image: elasticsearch:7.17.5container_name: esenvironment:- TZAsia/Shanghaiports:- 9200:9200volumes:- ./es/certs:/usr/share/elasticsearch/config/certs- ./es/data:/usr/share/elasticsearch/datanetworks:- my-netnginx:image: nginx:latestcontainer_name: nginxenvironment:- TZAsia/Shanghaiports:- 80:80- 443:443volumes:- ./nginx/html:/usr/share/nginx/htmlnetworks:- my-net
执行docker compose up -d命令后三个容器都没有启动成功。 执行docker logs minio查看日志
/opt/bitnami/scripts/libminio.sh: line 364: /bitnami/minio/data/.root_user: Permission denied其他两个服务的日志也差不多都是挂载的目录没有正确的权限。
解决办法
使用以下命令设置目录权限
chmod -R 777 挂载的目录路径二、Elasticsearch 启动的引导检查失败
es报错信息
ERROR: [2] bootstrap checks failed. You must address the points described in the following [2] lines before starting Elasticsearch.
bootstrap check failure [1] of [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
bootstrap check failure [2] of [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原因
max virtual memory areas 的限制过低需要增加到至少 262144。默认的发现设置对于生产环境来说是不合适的至少需要配置其中一个discovery.seed_hosts、discovery.seed_providers 或 cluster.initial_master_nodes。
解决办法
使配置es的环境变量

minio的账号长度必须大于等于5密码长度必须大于等于8位

折腾了快一天终于搞完了。说明一下这个是检验我们的docker compose掌握程度因此里面的镜像没有提前拉取挂载数据卷的目录也没有提前创建。虽然docker compose up执行后会自动帮你完成这些事但正规的做法是把docker compose用到的东西提前准备好这样能减少很多麻烦。 如果对你有帮助可以给个赞
