Question

我正在尝试在docker上下文中重新创建this tutorial中的步骤，在OS X上的virtualbox中运行的coreos下安装ubuntu映像。

我已经设置了一个Dockerfile，其中包含以下步骤：

# Install docker basics
RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
RUN apt-get update
RUN apt-get upgrade -y

# Install supervisor
RUN apt-get install -y supervisor
RUN mkdir -p /var/run/sshd
RUN mkdir -p /var/log/supervisor
RUN mkdir -p /etc/supervisor/conf.d

# tutorial suite
ADD ./etc/long.sh /usr/local/bin/long.sh
RUN /bin/chmod 0777 /usr/local/bin/long.sh
ADD ./etc/long_script.conf /etc/supervisor/conf.d/long_script.conf

# create supervisord user
RUN /usr/sbin/useradd --create-home --home-dir /usr/local/nonroot --shell /bin/bash nonroot

# start supervisord
RUN sudo service supervisor start

将以下文件复制到相对/etc/目录中：

long.sh：

#!/bin/bash
while true
do
    # Echo current date to stdout
    echo `date`
    # Echo 'error!' to stderr
    echo 'error!' >&2
    sleep 1
done

和long_script.conf：

[program:long_script]
command=/usr/local/bin/long.sh
autostart=true
autorestart=true
stderr_logfile=/var/log/long.err.log
stdout_logfile=/var/log/long.out.log

它正确地加载了所有内容，但是/var/log/long.out.log或/var/log/long.err.log中没有相应的输出，尽管这两个文件都存在于该目录中。

当我使用/bin/bash /加载图片时，我会尝试以下操作：

我可以成功运行service supervisor restart并获取Restarting supervisor:作为输出。
但是当我尝试使用supervisorctl运行任何功能时，我会收到错误，即unix:///var/run/supervisor.sock refused connection

我检查了/var/log/supervisor/supervisord.log的输出，它给了我：

2014-03-17 08:54:48,090 CRIT Supervisor running as root (no user in config file)
2014-03-17 08:54:48,090 WARN Included extra file "/etc/supervisor/conf.d/long_script.conf" during parsing

2014-03-17 08:54:49,165 INFO spawned: 'long_script' with pid 13
[error] client.go:2296 Error resize: Error: resize: bad file descriptor

谷歌搜索建议我包含一个明确指向应用程序supervisord.conf文件的准系统supervisord.sock文件，因此我将以下内容添加到Dockerfile中：

# Add supervisor config file
ADD ./etc/supervisord.conf /etc/supervisor/conf.d/supervisord.conf

然后添加了一个supervisord.conf文件，如下所示：

[supervisord]
logfile=/var/log/supervisor/supervisord.log
loglevel=error
nodaemon=false

[supervisorctl]
serverurl = unix:///var/run/supervisord.sock

包含此

我根本不再在long.err.log填充long.out.log或/var/log/。
我可以运行service supervisor restart，但现在当我运行supervisorctl时，我得到的错误更改为unix:///var/run/supervisord.sock no such file。

我检查了/var/log/supervisor/supervisord.log的输出，它给了我：

2014-03-17 08:48:29,715 CRIT Supervisor running as root (no user in config file)[error] client.go:2296 Error resize: Error: resize: bad file descriptor

认为这可能是用户权限问题，我尝试将supervisord.conf文件切换为

[supervisord]
logfile=/var/log/supervisor/supervisord.log
loglevel=error
nodaemon=false
user=nonroot

[supervisorctl]
serverurl = unix:///var/run/supervisord.sock

将以下内容添加到Dockerfile

RUN /usr/sbin/useradd --create-home --home-dir /usr/local/nonroot --shell /bin/bash nonroot

但是在编译时会出现以下错误

Step XX : RUN service supervisor start
 ---> Running in fdcb12ff3cfa
Traceback (most recent call last):
  File "/usr/bin/supervisord", line 9, in <module>
load_entry_point('supervisor==3.0a8', 'console_scripts', 'supervisord')()

FileHandler.__init__(self, filename, mode)
  File "/usr/lib/pymodules/python2.7/supervisor/loggers.py", line 106, in __init__
self.stream = open(filename, mode)

现在登录/bin/bash/并在cat上执行/var/log/supervisor/supervisord.log会产生：

2014/03/17 08:57:36 build: The command [/bin/sh -c service supervisor start] returned a non-zero code: 1

2014-03-17 08:54:49,165 INFO spawned: 'long_script' with pid 13
[error] client.go:2296 Error resize: Error: resize: bad file descriptor

这是什么问题？我只是希望能够通过supervisord运行这个shell脚本，并在日志文件中观察它的输出。

Answer 1

您也在开始服务 - 但不要让它继续运行。

RUN sudo service supervisor start

您可能应该直接运行它：

CMD ["/usr/bin/supervisord"]

您可能还需要/需要向该CMD添加一些参数。请参阅：Docker/Supervisord example

Answer 2

我也有这个问题而sudo没有帮助。因此，我不是使用unix套接字，而是使用tcp套接字代替：

[inet_http_server]
port=:9001
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=http://localhost:9001

您也可以仅绑定到localhost（127.0.0.1:9001）并添加可选的用户和密码。

Answer 3

我知道这是一个过时的问题。但是我发布了，因为你还没有接受答案。使用docker和supervisor时，请确保在前台运行supervisord。你可以通过改变你的supervisord.conf来做到这一点。设置

nodaemon=true

尝试在docker中重新创建supervisor教程，遇到错误（权限？）
