Using GIT to export knowledge repository on Drools KIE workbench

Scenario: we have developed assets (process models, rules, java codes, scripts, etc) on Computer1. The Workbench maintains these assets as repository. After development, we wish to deploy the developed project to another Computer2. This requires migrating the developed repository from Computer1 to Computer2.

Traditionally we copy the workbench environment to the target. This requires copying tens of gigabytes chunks, and thus suboptimal. Since Workbench uses Git to manage the versions, it should also support export/import through Git commands. Here is how to do it.

Prerequisites:

Computer1 & Computer2 have Git and KIE Workbench installed.

Steps

1. On Computer1, use git to get local copy of repository.

      – Create a local folder

– $ git clone git://localhost:{port}/{repo}.git

    – After the command completes, we get a local copy of the repository

2. Transfer the repository to Computer2, e.g., using file copying.

3. On Computer2, create organization and repository with the same name in Workbench.

– Create a local working repository using Git

– Create a new folder

– $ git init

– $ remote add origin ssh://admin@localhost:{port}/{repo}. This command will ask for the password “admin”.

– We can see a empty repository is pulled from the Workbench server.

4. Use the transferred files to cover the local repository, e.g., add sources, rules, workflows.

5. Push it back to Workbench using Git.

– $ git add .

– $ git commit -m “migrated from Computer2”

– $ git push origin master

6. In the workbench, refresh to see the imported repository.

That’s it.

Using this method, we have reduced Dev-Op deployment from days to minutes.

[TED]凯利麦克尼格尔-关于压力

  1. 对于同样的压力,认为「压力有害健康」的人有更高的死亡率,而认为「压力有益」的人则比无压力人群还要健康。后者产生的激素反映会展示出勇气。
  2. 压力反应本身产生的激素,会促使人寻求社交接触,而社交接触会缓解压力。也就是说,压力机制本身会导致压力的减轻。当然,关键在于是否能够获得社交接触来倾诉压力感觉。
  3. 在感受到压力时,去关爱别人的人,几乎没有在健康方面受到压力的影响。
也就是说,在面对压力时,如何看待,如何行动,来将压力转换为勇气、社交和关爱行为,影响着我们的生命。
她的建议是:
追寻有意义的生命,并相信自己能够很好地处理面对的挑战。
