[docker/redmine] run redmine with sqlite3 in docker

Basic Rule:
 I want to use "/home2/home/redmine" directory for redmine DB.
 I want to use sqlite3 for redmine.

1. in host side
 # adduser redmine

2. in host side. (go into dockers container for copying base files to host)
 # docker run -it -v /home2/home/redmine/:/usr/src/redmine/HOST --name redmine -p 80:3000 redmine bash

2-1. in redmine container of docker : work dir is /usr/src/redmine
 # cp -a config HOST/
 # cp -a db HOST/
 # exit
2-2. in host side : remove all docker contatiners
 # docker rm $(docker ps -a -q)
2-3. in host side : chown directories.
 # cd /home2/home/redmine
 # chown redmine.redmine . -R

3. edit "/home2/home/redmine/config/database.yml"

production:
  adapter: sqlite3
  database: sqlite/redmine.db
  host: localhost

4. Run Redmine with daemonized.
 # docker run -d -v /etc/passwd:/etc/passwd:ro -v /home2/home/redmine/DB:/usr/src/redmine/sqlite -v /home2/home/redmine/config:/usr/src/redmine/config -v /home2/home/redmine/files:/usr/src/redmine/files -v /home2/home/redmine/log:/usr/src/redmine/log/ -v /home2/home/redmine/tmp:/usr/src/redmine/tmp -v /home2/home/redmine/db:/usr/src/redmine/db --name redmine -p 80:3000 redmine

FAQ)
 1. Q) How to check errors?
  A) In host, use this command.
  # docker logs redmine
 2. Q) Why do I bind "/etc/passwd" volume?
  A) Because of redmine image needs redmine user privilege.
  So at first you made user redmine in host and bind /etc/passwd to redmine container.
