Docker部署fluentd 日志文件报错解决

volumes:
      - /home/.../fluentd/log/:/fluentd/log/

1.运行容器报错：
500 Internal Server Error
can't create buffer file for /fluentd/log/buffer.*.log. Stop creating buffer files: error = Permission denied @ rb_sysopen - /fluentd/log/buffer.b5b241f11f9b99d7dd50e39e09f07375f.log

解决方法：
chmod -R 777 /home/.../fluentd/log

2.运行容器报错：
{"level":"error","message":"config error file=\"fluentd/etc/fluent.conf\" error_class=Fluent::ConfigError error=\"out_file: `/fluentd/log/xxx.20201111.log` is not writable\""}

解决方法：
yml文件中添加配置：
    privileged: true
    stdin_open: true
    tty: true
