Docker 构建Supervisor 容器镜像

本文介绍构建Supervisor Docker镜像，在Docker容器内管理配置Supervisor。

Dockerfile:

FROM centos:7
MAINTAINER phonecom<18819470615@163.com>

# supervisor配置文件路径
ENV SUPERVISORD_CONF=/etc/supervisord.conf
# supervisor临时文件路径(日志文件、sock文件、pid文件)
ENV SUPERVISORD_TMP_CONF=/tmp/supervisor
# supervisor程序块文件路径,即是[program]块
ENV SUPERVISORD_INCLUDE_FILE=/etc/supervisordfile
# web管理界面的IP
ENV SUPERVISORD_WEB_IP=*
# web管理界面的PORT
ENV SUPERVISORD_WEB_PORT=9001
# web管理界面的账号
ENV SUPERVISORD_WEB_ACCOUNT=admin
# web管理界面的密码
ENV SUPERVISORD_WEB_PASSWORD=adminpass

RUN mkdir -p ${SUPERVISORD_TMP_CONF}
RUN mkdir -p ${SUPERVISORD_INCLUDE_FILE}

RUN yum -y update
RUN yum install -y python-setuptools wget telinit openssh openssh-server

USER root
EXPOSE 22 80 9001

RUN /usr/sbin/init &
RUN /usr/sbin/telinit &
RUN sshd-keygen -t rsa -N "" -f ~/.ssh/id_rsa &
RUN sshd-keygen

CMD ["sh", "-c", "supervisord -c /etc/supervisord.conf && tail -f /dev/null"]

构建镜像：

docker build -t super .

启动容器：

docker run -d -p 9001:9001 super

访问 http://your-host:9001，输入用户名密码（admin/adminpass)

cat /etc/supervisord.conf

[unix_http_server]
file=/tmp/supervisor/supervisor.sock
[inet_http_server]
port=*:9001
username=admin
password=adminpass

[supervisord]
logfile=/tmp/supervisor/supervisord.log
logfile_maxbytes=50MB
logfile_backups=10
loglevel=info
pidfile=/tmp/supervisor/supervisord.pid
nodaemon=false
minfds=1024
minprocs=200

[supervisorctl]
serverurl=unix:///tmp/supervisor/supervisor.sock
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[include]
files = /etc/supervisordfile/*.ini

[program:sshd]
command=/usr/sbin/sshd -D
