Jenkins combines ansible with shell for automated deployment and rollback

Recent continuous integration with jenkins+gitlab+ansible, automated deployment and version rollback. However, the Deploy plugin failed to do incremental upgrades and rollback operations, tossing a long time to decide to write their own script simple implementation.

Environment:

7.0 64-bit gitlab:v2. 9.0 git: 2.9  1.651. 3, git plugin, GitLab plugin, Dynamic Parameter plug-in ansible:2.1. 0.0

Various tool functions:

1, Gitlab do version management
2. Jenkins performs the deployment or rollback operations according to the specified parameters, as well as the presentation and recording of the execution results.
3. Ansible is responsible for remote execution of scripts.

All of the following are done on the premise that the above conditions are installed and available.

Deployment script:

#!/bin/SH#说明show_usage="args: [-L,-R,-B,-w]\[--local-repository=,--repository-url=,--backup-dir=,--webdir=]"#参数 # Local warehouse directory Opt_localrepo=""# git repository urlopt_url=""# backup Directory Opt_backupdir=""# web Directory opt_webdir=""Getopt_args=`getopt-O l:r:b:W:-al local-repository:,repository-url:,backup-dir:, WebDir:--"[email protected]"' eval set--"$GETOPT _args"#获取参数 while[-N" $" ] Do         Case " $" inch-l|--local-repository) opt_localrepo=$2;Shift 2;; -r|--repository-url) opt_url=$2;Shift 2;; -b|--backup-dir) opt_backupdir=$2;Shift 2;; -W|--webdir) opt_webdir=$2;Shift 2;; --) break;; *)Echo$1,$2, $show _usage; Esac Doneif[[-Z $opt _localrepo | |-Z $opt _url | |-Z $opt _backupdir | |-Z $opt _webdir]]; Then        Echo$show _usageEcho "Opt_localrepo: $opt _localrepo, Opt_url: $opt _url, Opt_backupdir: $opt _backupdir, Opt_webdir: $opt _webdir"Exit0fi# The directory where the deployment script is located scriptdir=`pwd'/jenkinsdeploy/mkdir-P $scriptdir # Current deployment version number Currversion= $scriptdir/currentversion.txt# Last deployment version lastversion= $scriptdir/Lastversion.txtif[!-F"$lastversion"]; Then        Echo "">$lastversionfi# git commit log Gitcommitlog= $scriptdir/gitcommitlog.txt# List of diff files between two versions Difffile= $scriptdir/Difffile.txt#if["$repodif" = = ""];then#        Echo "the warehouse local directory cannot be empty, please enter the local warehouse directory parameter!

Jenkins configuration: Add an optional parameter

This build is parameterized--Choice Parameter

The variable name is:

Deploy_envirenment

Variable Value:

Deployrollback

　　

Execute script:

Echo$deploy _envirenment Case$deploy _envirenmentinchdeploy)Echo "Deploy: $deploy _envirenment"ansible webservers-M script-a"~/bashscript/xxxxxx_deploy.sh--local-repository=/www/test/test--repository-url=git Warehouse Address--backup-dir=/www/ Test/bak--webdir=/www/test/www"        ;; Rollback)Echo "rollback: $deploy _envirenment"ansible webservers-M script-a'~/bashscript/xxxxxx_rollback.sh--backup-dir=/www/test/bak--webdir=/www/test/www'        ;; *) exit;;Esac

　　

Final execution

　　

Output log to perform rollback operations

This is simply the implementation of automated deployment and rollback operations, if done more intelligently, combined with the database can be made to roll back to a version, and so on.
