My team uses TeamCity for continuous integration. It will build, test and deploy web applications via Web Deploy to dev and qa web servers. The tricky part is deploying to a production web server - our policy dictates that developers cannot deploy to production, only a system administrator can.
Our current approach is to have TeamCity build a web deployment package, which the administrator can download and install on the production web server. However, we'd like to allow them to simply click "Run" on a build configuration, but we're not sure how to secure that button.
We could create a TeamCity project that only administrators have access to, but we also have to address Web Deploy security. The Web Deploy service needs to be authenticated with a local admin account on the production server. We don't want developers having access to the username/password in a build script, nor do we want every build agent running as this account since developers could create a build that uses it to deploy to production.
I've haven't had much luck finding resources on TeamCity security/deployment best practices, but I can't imagine we're the only company in this situation. How do others manage automated deployment security?
