Supervisord 服务未输出到 docker-compose 控制台

Question

我有一个 Docker 容器，里面运行着多个服务。我希望每个服务的输出都发送到控制台。这是一个开发容器，所以我想在工作时看到所有输出。

我试过这个文件：

[supervisord]
nodaemon=true
 
[program:sshd]
command=/usr/sbin/sshd -D
autostart=true
autorestart=true
 
[program:nginx]
command=/usr/sbin/nginx -g "daemon off;"
priority=900
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
username=www-data
autorestart=true
autostart=true

[program:php-fpm]
command=/usr/sbin/php-fpm7.4 -F
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
autostart=true
autorestart=true
priority=5


[program:memcached]
command=/usr/bin/memcached -u root
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
autostart=true
autorestart=true
priority=200

但它只输出监督消息，而不输出来自服务的消息。我看到另一个线程发送了日志消息，/dev/fd/1所以我也尝试了，但没有成功。

stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
redirect_stderr=true

我的基础图像是 ubuntu 20.04。

为什么我无法将服务日志消息发送到控制台？

首先，不要使用supervisord和docker，选择其中一个，如果您使用docker，请使用docker compose并使用docker拆分每个服务来控制进程，但如果您无论如何都要这样做...我启动了supervisor并supervisord -n更新了我的nginx配置以将日志发送到/ dev / stderr和/ dev / stdout，一切都按预期工作。 nginx的启动命令由supervisord发送到/ dev / stdout，nginx日志发送到nginx配置的位置，只有error_log可用于配置nginx启动参数，请参阅下面的具体链接。
