Docker container simultaneous start of multi-service

Docker container simultaneous start of multi-service

Reprint please specify from: http://blog.csdn.net/wsscy2004
Yesterday I stepped on a sinkhole, I have a basic mirror centos6.5+ssh, is through dockerfile build, using the cmd command to start SSH.

Through centos6.5+ssh mirroring, I want to build a rabbitmq mirror, dockerfile cmd to start the RABBITMQ service. Although I know that there is only one cmd in dockerfile, I do not expect to create another image and inherit the cmd from image.

With Docker's command inspect you can see that CMD has been replaced.

"CMD": [
   /usr/bin/supervisord "
],

Below to get to the point, how to start multiple services at the same time, mainly in the following ways supervisor

Supervisor is a tool for monitoring processes under Linux, starting all services through supervisor.

Create Dockerfile:

# Use the this image to the run multiple service
# Add service in supervisord.conf from

centos6-ssh
maintainer Edwards bean@gmail.com
run Yum install-y supervisor
run mkdir-p/var/run/sshd
run mkdir-p/var/log/supervisor
ADD supervisord.conf/etc/supervisord.conf
# Expose your port to host
expose
CMD ["/usr/bin/ Supervisord "]

Create supervisord.conf:

[Supervisord]
Nodaemon=true

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

#add another service#[program:hello]# Command=/bin/bash-c "/root/test.sh"

Made into Image:

Docker build-t Supervisord.

After that, you can add the service cmd startup script via supervisord.conf

Use the cmd command to start the script by encapsulating all the services to be started into a single script. But better Supervisord, not recommended.
