Question

我在centos创建了两个带有闪亮服务器的泊坞窗：

Docker与shiny server - 免费版here
Docker与shiny server pro（使用临时许可证）here

这些泊坞窗在centos上，因为它最终将作为Linux的受支持版本（可能是dockerised或native）在RHEL上运行。目前，它们为测试和开发提供了便利的方式。

它们主要用于开发：它们包括R，RStudio Server和Shiny Server：可能不是Docker纯粹主义者会做或推荐的（可能是生产版本将基于docker）组成）。

我遇到的问题是，虽然Docker shiny server - 免费版工作正常， Docker shiny server pro无法正常工作（也许是supervisord的问题？）。

这是非常令人惊讶的，因为代码库是常见的（当然）。可能是关于如何产生过程的问题？

如果有人帮我在shiny server pro配置中找到错误，那就太棒了。

Answer 1

我设法解决了这个问题。正如所料，这是Group 0: "(^\s+)" Captures whitespace Group 1: "(\*{3})" captures '***' Group 2:"([a-zA-Z\s]+)" captures alpha characters and spaces Group 3: "(\*{3})*" captures 0 or or more occurrences of "***"的错误配置。

闪亮的服务器需要以root身份启动，而我错误地使用了supervisord.conf而不是user=shiny。我很惊讶这并没有在免费版中产生错误。

这是后人的主管配置，使其成功：

user=root
