I'm trying to run 3 services at my container startup (snmpd, sshd and centengine)
As runlevel is unknown in the container, services won't start.
I built an image with this Dockerfile :
FROM centos:6.7
MAINTAINER nael <me@mail>
# Update CentOS
RUN yum -y update
# Install wget
RUN yum install -y wget
# Get Centreon Repo
RUN wget http://yum.centreon.com/standard/3.0/stable/ces-standard.repo -O /etc/yum.repos.d/ces-standard.repo
# Install Packages (SSH, sudo, Centreon Poller & Engine, SNMP)
RUN yum install -y --nogpgcheck openssh-clients openssh-server centreon-poller-centreon-engine sudo net-snmp net-snmp-utils
# Install supervisord
RUN rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RUN yum --enablerepo=epel install -y supervisor
RUN mv -f /etc/supervisord.conf /etc/supervisord.conf.org
ADD supervisord.conf /etc/
# For sshd & centengine
EXPOSE 22 5669
# Change user password
RUN echo -e "password" | (passwd --stdin user)
# Disable PAM (causing issues while ssh login)
RUN sed -ri 's/UsePAM yes/#UsePAM yes/g' /etc/ssh/sshd_config
RUN sed -ri 's/#UsePAM no/UsePAM no/g' /etc/ssh/sshd_config
# Start supervisord
CMD ["/usr/bin/supervisord"]
Here is the supervisord.conf file
[supervisord]
nodaemon=true
pidfile=/var/run/supervisord.pid
logfile=/var/log/supervisor/supervisord.log
[program:centengine]
command=service centengine start
[program:snmpd]
command=service snmpd start
[program:sshd]
command=service sshd start
But with this Dockerfile and supervisord.conf, when I start my container theses services aren't running.
What could be the problem ?
Not anymore using supervisord.
I just include a script with all the services ... start commands in the Dockerfile. When I create my container with docker run ... I just specify that I want to start it with my script.
& that's working very well.
Thanks @warmoverflow for trying to solve this.
