开发的Plugin部署到Redmine的服务中，最为简单的方式即是将整个内容进行打包，然后解开至Redmine的plugins目录中，重启Redmine的服务即可。

事前准备

事前在Redmine的开发环境中开发了一个名为sample的插件，此插件未实现任何功能，只有插件信息的设定，详细内容为：

详细Plugin创建的说明请参看如下内容：

生成待部署的plugin的tar文件包

liumiaocn:redmine liumiao$ docker exec -it redmine_redmine_1 sh
# ls plugins

在4000端口启动新的Redmine服务

按照如下步骤在4000启动新的Redmine服务

liumiaocn:redmine liumiao$ mkdir deploy
liumiaocn:redmine liumiao$ cp docker-compose.yml deploy/
liumiaocn:redmine liumiao$ cd deploy
liumiaocn:deploy liumiao$ vi docker-compose.yml 
liumiaocn:deploy liumiao$ diff docker-compose.yml ..
8c8
<       - 4000:3000
---
>       - 3000:3000
liumiaocn:deploy liumiao$ 
liumiaocn:deploy liumiao$ docker-compose up -d
Creating network "deploy_default" with the default driver
Creating deploy_redminedb_1 ... done
Creating deploy_redmine_1   ... done
liumiaocn:deploy liumiao$ 
liumiaocn:deploy liumiao$ docker-compose ps
       Name                     Command               State     Ports  
-----------------------------------------------------------------------
deploy_redmine_1     /docker-entrypoint.sh rail ...   Exit 1           
deploy_redminedb_1   docker-entrypoint.sh mysqld      Up       3306/tcp
liumiaocn:deploy liumiao$ 
liumiaocn:deploy liumiao$ docker-compose up -d
deploy_redminedb_1 is up-to-date
Starting deploy_redmine_1 ... done
liumiaocn:deploy liumiao$ 
liumiaocn:deploy liumiao$ docker-compose ps
       Name                     Command               State           Ports         
------------------------------------------------------------------------------------
deploy_redmine_1     /docker-entrypoint.sh rail ...   Up      0.0.0.0:4000->3000/tcp
deploy_redminedb_1   docker-entrypoint.sh mysqld      Up      3306/tcp              
liumiaocn:deploy liumiao$

此时Plugin的信息为空

将Plugin的tar文件展开到plugins目录下

部署Plugin只需要将上述的tar文件展开至plugins目录下即可。执行日志如下所示：

• 获取plugin并放入Redmine服务所在的容器中

liumiaocn:deploy liumiao$ docker cp redmine_redmine_1:/usr/src/redmine/sample-plugin.tar .
liumiaocn:deploy liumiao$ ls sample-plugin.tar
sample-plugin.tar
liumiaocn:deploy liumiao$ docker cp sample-plugin.tar deploy_redmine_1:/usr/src/redmine/
liumiaocn:deploy liumiao$

• 展开plugin文件至plugins目录下

liumiaocn:deploy liumiao$ docker exec -it deploy_redmine_1 sh
# pwd
/usr/src/redmine
# ls sample-plugin.tar
sample-plugin.tar
# ls plugins
README
# 
# tar xvpf sample-plugin.tar

plugins/sample/test/test_helper.rb
plugins/sample/test/fixtures/
plugins/sample/test/unit/
plugins/sample/init.rb

plugins/sample/app/models/
plugins/sample/app/controllers/
plugins/sample/lib/
plugins/sample/lib/tasks/
# 
# ls plugins

重启Redmine服务

使用docker restart命令重启Redmine服务

liumiaocn:deploy liumiao$ docker restart deploy_redmine_1
deploy_redmine_1
liumiaocn:deploy liumiao$

确认结果

可以看到Plugin的信息已经部署到新的Redmine的服务上了

总结

这里可以看到，只需要将plugin的实现内容放置Redmine的plugins目录下并重启服务，插件即生效。但是需要注意的是，相关的实现均在相对目录sample下这一点是实现这一点的前提。之所以有部署Plugin的操作，在实际的场景中是多种多样的，比如自定义开发的内容较多，而生产环境的Redmine的服务较为简洁，或者Redmine的服务升级需要保证之前的插件能够正常动作等。
