运行 使用 AWS 用户数据的 Capistrano 部署任务
Running a Capistrano deployment task with AWS user-data
我的情况：我有一个 AMI，其中有一个 deploy/ 文件夹，其中包含我用来在本地主机上部署生产应用程序的 capist运行o 文件
我计划使用来自 Autoscaling 组的用户数据脚本，以便在该组每次扩展并生成新机器时部署最新版本的服务器
脚本必须运行作为用户ubuntu
这是我的用户数据
cd /home/ubuntu/
aws s3 cp s3://mybucket-config/production/rails/startup_script.sh ./startup_script.sh --region my-region
chmod +x ./startup_script.sh
chown ubuntu:ubuntu ./startup_script.sh
su - ubuntu -c "./startup_script.sh"
这个启动脚本包含
cd /home/ubuntu/deploy/
git pull
git checkout production
cap aws_localhost_production deploy
我 运行 在 cap deploy 期间收到了一条奇怪的错误消息，我在 google 上没有找到很多关于这个
的参考资料
