Docker – 芹菜作为守护进程 – 找不到pidfiles

我似乎在这里尝试了所有的解决scheme，但似乎没有任何工作，我不知道我错过了什么。 我试图通过我的docker容器运行芹菜作为守护进程。

root@bae5de770400:/itapp/itapp# /etc/init.d/celeryd status celery init v10.1. Using config script: /etc/default/celeryd celeryd down: no pidfiles found root@bae5de770400:/itapp/itapp# /etc/init.d/celerybeat status celery init v10.1. Using configuration: /etc/default/celeryd celerybeat is down: no pid file found root@bae5de770400:/itapp/itapp# 

我已经看过很多关于烫发的post，我已经尝试过所有这些都无济于事。

这是我的docker文件，它创build所有的烫发和文件夹

 FROM python:latest ENV PYTHONUNBUFFERED 1 # add source for snmp RUN sed -i "s#jessie main#jessie main contrib non-free#g" /etc/apt/sources.list # install dependancies RUN apt-get update -y \ && apt-get install -y apt-utils python-software-properties libsasl2-dev python3-dev libldap2-dev libssl-dev libsnmp-dev snmp-mibs-downloader git vim # copy and install requirements RUN mkdir /config ADD /config/requirements.txt /config/ RUN pip install -r /config/requirements.txt # create folders RUN mkdir /itapp; RUN mkdir /static; # create celery user RUN useradd -N -M --system -s /bin/false celery RUN echo celery:"*****" | /usr/sbin/chpasswd # celery perms RUN groupadd grp_celery RUN usermod -a -G grp_celery celery RUN mkdir /var/run/celery/ RUN mkdir /var/log/celery/ RUN chown root:root /var/run/celery/ RUN chown root:root /var/log/celery/ # copy celery daemon files ADD /config/celery/init_celeryd /etc/init.d/celeryd RUN chmod +x /etc/init.d/celeryd ADD /config/celery/celerybeat /etc/init.d/celerybeat RUN chmod +x /etc/init.d/celerybeat RUN chmod 755 /etc/init.d/celeryd RUN chown root:root /etc/init.d/celeryd RUN chmod 755 /etc/init.d/celerybeat RUN chown root:root /etc/init.d/celerybeat # copy celery config ADD /config/celery/default_celeryd /etc/default/celeryd # RUN /etc/init.d/celeryd start # set workign DIR for copying code WORKDIR /itapp 

如果我手动启动它的作品

 celery -A itapp worker -l info /usr/local/lib/python3.6/site-packages/celery/platforms.py:795: RuntimeWarning: You're running the worker with superuser privileges: this is absolutely not recommended! Please specify a different user using the -u option. ...

init.d文件是从芹菜仓库复制，这是我的默认文件的内容，如果有帮助

 # Names of nodes to start # most people will only start one node: CELERYD_NODES="worker1" # but you can also start multiple and configure settings # for each in CELERYD_OPTS #CELERYD_NODES="worker1 worker2 worker3" # alternatively, you can specify the number of nodes to start: #CELERYD_NODES=10 # Absolute or relative path to the 'celery' command: CELERY_BIN="/usr/local/bin/celery" # App instance to use # comment out this line if you don't use an app CELERY_APP="itapp" # or fully qualified: # Where to chdir at start.

CELERYD_LOG_FILE="/var/log/celery/%n%I.log" CELERYD_PID_FILE="/var/run/celery/%n.pid" # Workers should run as an unprivileged user. # You need to create this user manually (or you can choose # a user/group combination that already exists (eg, nobody). CELERYD_USER="celery" CELERYD_GROUP="celery" # If enabled pid and log directories will be created if missing, # and owned by the userid/group configured. CELERY_CREATE_DIRS=1 

在这个文件中可能是错误的唯一的东西，我认为是CELERY_BIN值，我不知道该怎么设置在docker集装箱

谢谢

所以你在Dockerfile中几乎没有问题

• Celery进程shell被设置为/bin/false ，这不允许任何进程启动。
• 您需要将/var/run/celery和/var/log/celery权限授予celery用户
• /etc/default/celeryd应该是640的权限
• Dockerfile中也有太多的图层

所以我更新了Dockerfile到下面

 FROM python:latest ENV PYTHONUNBUFFERED 1 # add source for snmp RUN sed -i "s#jessie main#jessie main contrib non-free#g" /etc/apt/sources.list # install dependancies RUN apt-get update -y \ && apt-get install -y apt-utils python-software-properties libsasl2-dev python3-dev libldap2-dev libssl-dev libsnmp-dev git vim # copy and install requirements RUN mkdir /config ADD /config/requirements.txt /config/ RUN pip install -r /config/requirements.txt # create folders RUN mkdir /itapp && mkdir /static; # create celery user RUN useradd -N -M --system -s /bin/bash celery && echo celery:"B1llyB0n3s" | /usr/sbin/chpasswd # celery perms RUN groupadd grp_celery && usermod -a -G grp_celery celery && mkdir -p /var/run/celery/ /var/log/celery/ RUN chown -R celery:grp_celery /var/run/celery/ /var/log/celery/ # copy celery daemon files ADD /config/celery/init_celeryd /etc/init.d/celeryd RUN chmod +x /etc/init.d/celeryd ADD /config/celery/celerybeat /etc/init.d/celerybeat RUN chmod 750 /etc/init.d/celeryd /etc/init.d/celerybeat RUN chown root:root /etc/init.d/celeryd /etc/init.d/celerybeat # copy celery config ADD /config/celery/default_celeryd /etc/default/celeryd RUN chmod 640 /etc/default/celeryd # set workign DIR for copying code ADD /itapp/ /itapp/itapp WORKDIR /itapp 

然后进入Web服务容器，一切正常
