错误消息 "Crit uncaptured python exception" 而运行 supervisord on docker

Question

我正在 docker 容器上尝试 supervisord 以尝试控制容器内的两个进程。现在，process1 每 10 秒键入一次“我是进程 1”，进程 2 键入“我是进程 2”。它们都是非常简单的 bash 脚本。

在 docker 日志中我遇到了这个错误：

我的 Dockerfile 如下所示：

FROM debian:bullseye
WORKDIR /app
COPY . /app
COPY ./supervisord.conf /etc/supervisor/conf.d/supervisord.conf
RUN apt-get update && apt-get install -y  supervisor && apt-get install -y procps
#RUN apt-get install -y python3-pip && pip install supervisor-stdout
CMD ["/usr/bin/supervisord"]

我的 supervisord.conf 看起来像这样：

[supervisord]
nodaemon=true

[program:program1]
command=/bin/bash /app/process1.sh &
process_name=PROGRAM1
autostart=true
autorestart=true
priority=0
redirect_stderr=true
stdout_logfile=/dev/stdout
stderr_logfile=/dev/stderr

[program:program2]
command=/bin/bash /app/process2.sh &
process_name=PROGRAM2
autostart=true
autorestart=true
priority=0
redirect_stderr=true
stdout_logfile=/dev/stdout
stderr_logfile=/dev/stderr

这里发生了什么？我的配置有问题吗？

谢谢！

我知道是怎么回事了。您需要指定日志文件的最大大小为 0，因为主管无法在 /dev/stdout.

上写入文件

在每个节目中：

stdout_logfile_maxbytes = 0
stderr_logfile_maxbytes = 0
