OpenCPU Docker 停止一次后无法重启

Question

我使用

安装了 opencpu Docker 映像

docker pull opencpu/ubuntu-16.04。

第一次成功启动。但是如果我终止进程并尝试使用命令再次启动它

docker run -it imageID

每次都会终止。需要有关如何成功启动它的建议。

也许这可以给你一些提示......这不是完全的解决方案，但如果在高层次上给你什么可能是原因并导致解决方案i.enter link description here

Answer 2

这似乎是rstudio-server 包的问题。我会将上面建议的解决方法 (server-app-armor-enabled=0) 添加到 opencpu docker 映像中。

请注意，opencpu/base 映像确实安装了 rstudio，因此您可能想试试这个。

Answer 3

什么是输出 sudo docker logs <container-name> ? 很可能它表明 httpd pid 存在。这意味着您需要删除容器中的 apache2.pid。但是现在由于容器没有启动，黑客就是编辑位于/var/lib/docker/containers/<container-long-id>/ 的容器的 config.v2.json 文件 在 CMD 部分，将“service cron start && apachectl -DFOREGROUND”更改为“rm -f /var/run/apache2/apache2.pid && service cron start && apachectl -DFOREGROUND”。这将确保您的容器将启动。为我工作！
