自动化工具后起之秀Ansible的部署实践

阅读更多关于自动化工具后起之秀Ansible的部署实践

转载本文需注明出处：微信公众号EAWorld，违者必究。从早期手动加脚本的部署方式，到后来自动化工具（chef, puppet, saltstack, ansible等）的出现，再到如今DevOps的盛行，企业应用部署正式进入平台部署阶段，CD（持续部署）已经成为企业对应用部署的标准需求，运维的交付也不再是以周或天为单位，而是以分钟为单位。本文主要介绍自动化工具Ansible，及其在普元DevOps平台中的应用部署和日常应用部署中的实践。本文目录：一、如何选择合适的自动化工具？二、Ansible架构图及工作流程三、DevOps基于Jenkins+Ansible+GitLab的部署实践四、Ansible日常应用部署实践五、总结一、如何选择合适的自动化工具？面对众多的自动化工具（chef, puppet, saltstack, ansible等），我们该如何选择适合自己的呢？总的来说，无外乎从以下几点来权衡利弊。活跃度（GitHub活跃度，社区活跃度）学习成本使用成本编码语言性能各种开源的自动化工具在GitHub的关注度是其活跃度最直观的体现，从图中Contributors这一项就可以看出Ansible和SaltStack的开源项目贡献者远远多于其它几种自动化工具。越活跃的开源项目往往意味着更完善的功能和更高效的问题解决率。 Ansible

GitLab merge behavior - keep file from branch

阅读更多关于 GitLab merge behavior - keep file from branch

问题 Is it possible to default to one branche's version of a file when doing merge requests in GitLab Web Interface? I'm trying to set up the GitLab Web Interface, so that you can use the graphical interface to do merge requests. In these merge requests, certain files on the target branch must not be subject to any changes. Most often, I'm working on web projects with a config.php, and here we can see how it's possible to not overwrite the config in branch 'prod' with anything (ie from 'dev')

问题 I am moving a few private Go projects to GitLab while getting rid of Godeps , Go dep with vendor directory and all of that because I would like to use just Go modules. I am using Go version: go1.12.6 linux/amd64 . I have a private "library" project / git repository at gitlab.com/my-company/my-team/my-library . This works as a Go module with go.mod and go.sum . I would like to use my-library as a dependency for another project, this: gitlab.com/my-company/my-team/my-project . The structure of

Gitlab shared runner set concurrence for each project

阅读更多关于 Gitlab shared runner set concurrence for each project

问题 A shared runner is used by dozens of our project. I set concurrent = 5 in config.toml, so my runner can do 5 job concurrently for all project. For example, the following scenario：3 job for A project, 2 job for B project, 0 job for C project which causes C project should wait for at least 1 job of A or B project being finished until it starts first job. I want to set like "all project concurrent = 5 " and "each project concurrent = 2 ". Is there any way to deal with it? 回答1: There is an open

DevOps之代码模块设计浅析
