Finding a simple fabfile with a working example of SSH keyfile usage isn’t easy for some reason. I wrote a blog post about it (with a matching gist). Basically, the usage goes something like this: from fabric.api import * env.hosts = [‘host.name.com’] env.user=”user” env.key_filename=”/path/to/keyfile.pem” def local_uname(): local(‘uname -a’) def remote_uname(): run(‘uname -a’) The important part … Read more
I do this by declaring an actual function for each environment. For example: def test(): env.user=”testuser” env.hosts = [‘test.server.com’] def prod(): env.user=”produser” env.hosts = [‘prod.server.com’] def deploy(): … Using the above functions, I would type the following to deploy to my test environment: fab test deploy …and the following to deploy to production: fab prod … Read more
