好好睇睇

@mritd v 友你也是 Ubuntu 16 吗？有个问题想请教一下你，我用 journalctl -u docker.service 进入日志查看想要复制日志，发现日志太长，我在手机上用选中的方式没法全部都复制下来，这种情况有什么命令适合将日志全部复制出来吗？

@mritd 国外论坛昨晚很多人发帖反馈了，我们论坛里面这么少人用容器吗？怎么都没人反馈呀？我还差点以为是我其他软件出问题了，怎么都想不到是这个？

@mritd 昨天晚上就已经挂掉了。让我排查一整天。你这样管用吗？我是先把自动升级给关掉了。

@Sasasu 谢谢大佬，请问一下 docker log 日志太长，手机 iOS 无法让我在一个屏幕內复制所有日志內容，因为使用方向键移动之后复制出来的内容只能是当前屏幕内容 , 有什么命令可以方便地复制所有日志內容？

网上搜索到一个 command，但是还是没办法复制到剪切板。
Journalctl -u docker 2>&1 | tee /tmp/cmd.out

You can also run your commands in the script command which will log the output to disk. Or you can: command 2>&1 | tee /tmp/cmd.out to log the output for future investigation in you wanted a (practically) infinite sized output history.

这种方法有人试过吗？

现在 iOS 端网页版修改 gist 都找不到按钮，App 上又没有整合进去。请问大家都是怎么处理？

大家都没碰到过吗?

@sleepm 谢谢大佬! 多次测试发现只有自定义创建的 bridge 才有 dns 解析. 另外想请问您是如何让 docker daemon 守护进程不退出的? 突然收到服务监控通知, 发现 docker 上 4 个容器服务同时挂掉了, journalctl -u docker.service 进入日志查看发现了这个, 该如何排错呢? 另外想请教您现在都在用哪种方法让 docker daemon 守护进程不退出? 谢谢您的指点!

支持下

关注你

@huijian222 V 友请问你有香港朋友吗？另外香港现在不是关口还没开放吗？

@Caan07 公钥文件可以公开没关系。
