docker build 的镜像，ssh 的密码在 build 的时候设置的，非常奇怪是的，容器启动后，正常可以用 ssh 登录，但过一天后，新开窗口重新 ssh 登录，密码就不对了，而且昨天开的已登录窗口还能正常使用。 重启 docke 容器后，又能正常登录，是啥原因啊? 没有人改密码啊，好几天都是这样，都是通过重启容器来解决，不清楚原因是啥

 | 3 PbCopy111 2021-06-02 20:33:36 +08:00 这。。。不是每次生成新密码么。。。。。 |
 | 5 killva4624 2021-06-03 10:44:21 +08:00 1 、ssh 的时候具体报错是什么？（可以用 -v 打印出来） 2 、“重启容器”的具体操作是什么？ docker restart xxx 吗，还是每次都重新 build ？看 Dockerfile，如果不重新 build 的话，这个 image 的 sshpassword 是不会变的。 |

| 7 css3 OP @killva4624 肯定不是 build 啊，直接 restart，或者直接 run |
