Shell脚本—Gitlab代码库备份

应公司要求，需每月对代码库进行备份刻录光盘进行保存，故想到写一个自动备份的脚本，并通过邮件进行通知。
因公司gitlab代码库是通过docker进行启动，故备份需对代码库和docker镜像同步进行备份，备份脚本内容如下

#!/usr/bin/bash
## gitlab backup
## by shanhai
gitlab_docker_id=`docker ps | grep gitlab-ce | awk '{print $1}'`
gitlab_image_id=`docker images | grep gitlab-ce | awk '{print $3}'`

gitlab_backup(){
	docker exec -it $gitlab_docker_id gitlab-rake gitlab:backup:create
	find /home/gbase/app/gitlab/data/backups/ -name "*_13.2.6_gitlab_backup.tar"
	if [ $? -eq 0 ];then
		cp /home/gbase/app/gitlab/data/backups/*_13.2.6_gitlab_backup.tar /data/gitlab_backup
		cp /home/gbase/app/gitlab/config/gitlab.rb /data/gitlab_backup
		cp /home/gbase/app/gitlab/config/gitlab-secrets.json /data/gitlab_backup
	else
		echo "gitlab backup faild,Please check it"
		exit
	fi
}

images_backup(){
	cd /data/gitalb_backup
	docker save -o gitlab_image_backup_`date +%F`.tar.gz $gitlab_image_id
	find /data/gitlab_backup/ -name "gitalb_image_backup_`date +%F`.tar.gz" && find /data/gitlab_backup/ -name "*_13.2.6_gitlab_backup.tar"
	if [ $? -eq 0 ];then
		/usr/bin/python3 /home/gbase/app/gitlab_backup.py
	
	else
		echo "gitlab image backup faild,Please check it"
		exit
	fi
}

邮件发送脚本如下
