Capistrano authorization How-To
Cap has made our deployments simple, fast, and reliable. However, it can only access services you yourself have access to. Establishing this access for the first time can be a bit of a trick.
If you have previously deployed this project:
cap [STAGE] deploy
- Have a beer; you're living the dream.
If it is your first deploy to a pre-existing destination:
Plan A should to ask your sysadmin for access. However, if you are the sysadmin, or there isn't one in the picture, here are some pointers. First, familiarize yourself with how SSH keys work.
All of the tasks that cap will need to perform can be verified manually. Unless otherwise noted, all commands should be run from your local box.
- This should connect you to the host, without prompting for the password. If not, update
~/.ssh/authorized_keyson the destination.
ssh email@example.com ssh firstname.lastname@example.org uname
- If your server is accessed via a gateway (common in some production environments), this will test your connection through that gateway. Your key will need to be authorized on the gateway, on the destination, and (for some cap tasks) the deploy@gateway user's key must be authorized on the destination.
If you are setting up a new destination:
git ls-remote <repository>
- Run this command from the destination host, while logged in as the deploy user. If it doesn't work you'll need to authorize the deploy user to access your repository. We use a special github account for this purpose.
- This should also be run as the deploy user, and will verify you have write access to the appropriate directory (the directory, such as
/var/wwwis specified by
:deploy_toin your config file.)
cap [STAGE] deploy:setup
- This will initialize the destination.
It's generally safe to attempt
cap deploy iteratively. If it doesn't work, study the output and try to figure out what cap was trying to do when it failed. By repeating that step manually, you can often discover where the hang-up is.
Hi was this a fix for GitHub? I'm a bit confused.

Not specifically - github works fine with cap, but like any other VCS the authorization issue needs to be dealt with.
