所以我为一个项目编写了一个Dockerfile,我已经定义了一个CMD来启动容器以运行应用程序.

Dockerfile看起来像

# create our mount folders and volumes
ENV MOUNTED_VOLUME_DIR=sites
RUN mkdir /$MOUNTED_VOLUME_DIR
ENV PATH=$MOUNTED_VOLUME_DIR/sbin:$MOUNTED_VOLUME_DIR/common/bin:$PATH
RUN chown -Rf www-data:www-data /$MOUNTED_VOLUME_DIR

# Mount folders
VOLUME ["/$MOUNTED_VOLUME_DIR/"]

# Expose Ports
EXPOSE 443

# add our environment variables to the server
ADD ./env /env

# Add entry point script
ADD ./start.sh /usr/bin/startContainer
RUN chmod 755 /usr/bin/startContainer

# define entrypoint command
CMD ["/bin/bash","/usr/bin/startContainer"]

start.sh脚本,做一些git的东西,如克隆正确的repo,设置环境变量,以及启动主管.

启动脚本以此开头

#!/bin/bash

now=$(date +"%T")
echo "Container Start Time : $now" >> /tmp/start.txt
/usr/bin/supervisord -n -c /etc/supervisord.conf

我像这样开始我的新容器

docker run -d -p expoPort:contPort -t -i -v /$MOUNTED_VOLUME_DIR/$PROJECT:/$MOUNTED_VOLUME_DIR $CONTAINER_ID /bin/bash

当我登录到容器时,我看到主管还没有启动,也没有Nginx或PHP5-fpm.带有从startContainer脚本设置的时间戳的/tmp/start.txt文件不存在,表明它从未在Dockerfile中运行过CMD.

任何有关修复此问题的提示都会很棒
