r - docker 与 Shiny 的服务器专业版问题

Question

我在centos上创建了两个带有 Shiny 服务器的docker:

• 带有 Shiny 服务器的Docker - 免费版here
• 带有 shiny server pro 的 Docker(使用临时许可证)here

这些 docker 运行在 centos 上，因为假设最终将作为受支持的 Linux 版本(可能是 dockerized 或 native )在 RHEL 上运行。目前它们提供了一种便捷的测试和开发方式。

它们主要是为开发而设计的:它们包括 R、RStudio Server 和 Shiny Server:可能不是 Docker 纯粹主义者会做的事情，或者推荐(可能生产版本将基于 docker compose)。

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

这非常令人惊讶，因为代码库是通用的(当然)。也许是关于进程如何生成的问题？

如果有人能帮助我找到 shiny server pro 配置中的错误，那就太好了。

Answer 1

我已经成功解决了这个问题。正如预期的那样，这是 supervisord.conf 的错误配置。

Shiny 服务器需要以 root 身份启动，而我错误地使用了 user=shiny 而不是 user=root。令我惊讶的是，这在免费版本中没有产生错误。

这里为后代提供了使其工作的主管配置:

[supervisord]
nodaemon=true
logfile=/var/log/supervisor/supervisord.log
pidfile = /tmp/supervisord.pid

[program:rserver]
user=root
command=/usr/lib/rstudio-server/bin/rserver
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
startsecs=0
autorestart=false
exitcodes=0

[program:shinyserver]
user=root
startsecs = 0
command=/bin/bash -c "exec shiny-server >> /var/log/shiny-server.log 2>&1"
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
autorestart=false
redirect_stderr=true
