redmine迁移

1. 在ubuntu14.04 上pull镜像redmine（注意版本为3.1.6）

docker pull redmine:3.1.6

 

2. 创建主机目录 /srv/redmine，将原主机上的compose.yml和run拷贝过来，将备份（files目录和redmine.db数据库文件）也拷贝过来

root@karl-v1:/srv/redmine# ls -ahl
total 9.5M
drwxr-xr-x 3 root root   4.0K May  8 11:16 .
drwxr-xr-x 6 root root   4.0K May  7 16:01 ..
-rw-r--r-- 1 root root    283 May  8 10:41 compose.yml
drwxrwxr-x 6  999 docker 4.0K May  7 16:23 files
-rw-r--r-- 1  999 docker 9.4M May  8 11:11 redmine.db
-rwxr-xr-x 1 root root   2.2K May  7 16:00 run
root@karl-v1:/srv/redmine#

 

3. 编辑compose.yml，将备份内容映射到容器中

root@karl-v1:/srv/redmine# cat compose.yml
data:
  image: busybox
  entrypoint: /bin/true
  volumes:
    - /srv/redmine/files:/usr/src/redmine/files

main:
  image: redmine:3.1.6
  volumes_from:
    - data
  volumes:
    - /tmp:/tmp
    - /srv/redmine/redmine.db:/usr/src/redmine/sqlite/redmine.db
  ports:
    - "3000:3000"
root@karl-v1:/srv/redmine#

 

4. 运行redmine容器

root@karl-v1:/srv/redmine#  docker-compose -f compose.yml -p redmine up -d

 

5. 检查redmine容器是否正常运行，并验证redmine页面能否打开

## 检查redmine容器日志
root@karl-v1:/srv/redmine# docker logs redmine_main_1
