docker-compose logs 查看实时日志（日志最后的N行、某刻后日志） 实践笔记

• 1.参数说明
• 2.我以rabbitmq为例
  • 2.1.全屏滚到底部结束
  • 2.2.全屏滚到底部并继续持续输出日志
  • 2.3.全屏滚到底部并继续持续输出日志并显示时间戳
  • 2.4.全屏滚到底部显示最后N行并继续持续输出日志并显示时间戳
• 3.总结对比一下

1.参数说明

View output from containers.

Usage: logs [options] [SERVICE...]

Options:
    --no-color          Produce monochrome output.
    -f, --follow        Follow log output.  实时输出日志，最后一行为当前时间戳的日志
    -t, --timestamps    Show timestamps. 显示时间戳
    --tail="all"        Number of lines to show from the end of the logs for each container.    
    						显示最后多少行日志， 默认是all （如： -tail=10 : 查看最后的 10 行日志。）

2.我以rabbitmq为例

2.1.全屏滚到底部结束

#docker-compose logs 全屏滚到底部结束

docker-compose logs

2.2.全屏滚到底部并继续持续输出日志

#docker-compose logs -f 全屏滚到底部并继续持续输出日志

docker-compose logs -f

2.3.全屏滚到底部并继续持续输出日志并显示时间戳

2.4.全屏滚到底部显示最后N行并继续持续输出日志并显示时间戳

docker-compose logs -f -t --tail=10

3.总结对比一下
