Artifactory 与 Jenkins 集成

上一篇 初识 JFrog Artifactory,介绍了什么是 Artifactory,以及如何安装、启动和升级。

本篇介绍 Artifactory 与 Jenkins 的集成,因为没有与 CI 工具集成的 Artifactory 是没有灵魂的。

通过集成,可以让 Jenkins 在完成构建之后,可以直接将制品(比如 build)推送到 Artifactory,供测试下载、部署或是后续的 Jenkins 任务去继续进行持续集成。

初识 JFrog Artifactory

什么是 Artifactory

Artifactory 是 JFrog 的一个产品,用作二进制存储库管理器。二进制存储库可以将所有这些二进制统一托管,从而使团队的管理更加高效和简单。

就跟你用 Git 一样,Git 是用来管理代码的,Artifactory 是用来管理二进制文件的,通常是指 jar, war, pypi, DLL, EXE 等 build 文件。

我觉得使用 Artifactory 的最大优势是创造了更好的持续集成环境,有助于其他持续集成任务去 Artifactory 里调用,再部署到不同的测试或开发环境,这对于实施 DevOps 至关重要。

如何设置 NFS 共享以及在不同的平台 Windows/Linux/Unix 进行挂载

例如我有一个共享仓库的代码所在用的空间非常大(超过 20 G),在每个产品构建时候都需要用到这个仓库的代码(从里面 copy 第三方库),如果每个人都要 git clone 这个第三方仓库,一是网络开销非常大,二是 git clone 时间长,而且占用大量的物理空间。

这可以通过 NFS 共享来解决。

另外希望这个代码仓库能自动更新,这里引入了 Jenkins。用它来检查如果这个容量巨大的仓库有代码提交就自动执行 git pull 操作,更新最新的代码到共享服务器上。

解决 Could not read from remote repository 问题

最近我在运行 Jenkins Job 时候突然发现 git clone 代码的时候突然报了这个错误:

$ git clone ssh://git@git.companyname.com:7999/repo/opensrc.git
Cloning into 'opensrc'...
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

这个错误只在我刚开始使用 git 的时候遇到过,那时候我还不知道如何使用 ssh 的方式来 clone 代码。怎么会出现这个错误呢?我也没改过什么,非常不理解。

Git Commit Squash

If your commits on local not pushed to remote

combine local commits, you could follow this flow

Here is short video (only 3 minutes) and good explanation of git rebase -i usage.

list your local repository log

list your logs in oneline

If you want to combine these 3 commits (add6152, 3650100, 396a652) to 1 commit, execute this command

git rebase -i HEAD~3      # last three commits

list last three commits

Select which commit you want to squash (type s or squash are OK)

combine three commits to one

then press ESC, enter :wq! to save and exit.

comment out some commits message you don't need

Comment out some commits message you don’t need, press ESC, enter :wq! to save and exit.

comment out some commits message you don't need

Check log, you will see your local repository logs has combine to one commit

comment out some commits message you don't need

If your commits had pushed to remote

combine remote commits, you could follow this flow

list your repository logs

list your logs in oneline

# so you can create another branch from bugfix/UNV-1234 named bugfix/UNV-1234-for-squash
xshen@dln-l-xs01 MINGW64 /c/U2GitCode/git-test (bugfix/UNV-1234)
$ git checkout -b bugfix/UNV-1234-for-squash
Switched to a new branch 'bugfix/UNV-1234-for-squash'

# combine last 2 commits
$ git rebase -i HEAD~2

change one commit from pick to squash, see the screenshot below. press ESC, enter :wq! to save and exit.

select a commit you want to squash

change commit message, for example “UNV-1234 combine all commit to one commit”, then press ESC, enter :wq! to save and exit.

comment out commit message you don't want to display

# push your new create branch to remote.
git push -u origin bugfix/UNV-1234-for-squash

Jenkins troubleshooting summary

ERROR: Error cloning remote repo ‘origin’ timeout=10

Recently, my Jenkins build failed when execute git clone with following this error message: ERROR: Error cloning remote repo ‘origin’.

  1. first I suspect it is the network reason, maybe because clone from Bitbucket need took up a lot bandwidth during git clone and causing this disconnection. but when I try to git clone on the agent, it works well.
  2. Then I noticed the there is timeout=10 in the Jenkins console log, I suddenly remembered that I deleted a very large folder a few days ago from git repo, and this may cause the repo more bigger, so it may take more time do a complete clone and it exceeds the Jenkins default clone timeout 10.

Googling and finally I found this issue JENKINS-47660 which is the same problem as mine.

如何通过 Jenkins 进行资源的锁定和释放

业务场景

日常工作中需要切换到不同平台(包括 Linux, AIX, Windows, Solris, HP-UX)不同的版本进行开发和验证问题,但是由于虚拟机有限,并不能保证每个开发和测试都有所以平台的虚拟机并且安装了不同的版本,因此准备各种各样的开发和测试环境会花费很长时间。

在大型企业里维护多分支流水线

Jenkins 是 DevOps 领域里非常好的 CI/CD 工具,它凭借其独特的功能,几乎可以满足你一切的的业务要求。其中一个独特的功能是多分支流水线(Multi-branch 流水线),可以动态配置流水线。但是,随着公司的发展,单独的多分支流水线并不能完全满足你的所有需求,特别是在涉及大型企业时,你需要考虑流水线的集中管理,治理,稳定性,限制和安全性等其他事项。因此对于具有 Jenkins 流水线的大规模 CI/CD 环境,你需要添加之前没有想到的更多功能。
