Question

I am using paramiko and create some virtualenvs over ssh like so:

from paramiko import SSHClient, SSHConfig

def ssh_connect(self):
    # ssh config file
    config = SSHConfig()
    config.parse(open(settings.SSH_CONFIG))
    o = config.lookup('my_key')

    # ssh client
    ssh_client = SSHClient()
    ssh_client.load_system_host_keys()
    ssh_client.connect(o['hostname'], username=o['user'])
    return ssh_client

def create_virtualenv(self):
    ssh = self.ssh_connect()
    venv_path = '/srv/virtualenvs/%s' % self.domain
    cmd = 'virtualenv %s' % env_path
    stdin = ssh.exec_command(cmd)
    self.create_database()
    ssh.close()

Now I ran into a bit of a wall here because I want to also install Django into this newly create virtualenv with pip. I tried a postmkvirtualenv hook because I do have virtualenvwrapper installed on that server but that does not seem to run when I create a new environment using the code above.

Can anyone give me any hints as to how I can install Django in this manner?

Did you try using the workon command? This command is part of virtualenvwrapper and allows you to activate a given virtualenv, you should be able to do something like this:

def create_virtualenv(self):
    ssh = self.ssh_connect()
    venv_path = '/srv/virtualenvs/%s' % self.domain
    cmd = 'workon %s; pip install Django' % env_path
    stdin = ssh.exec_command(cmd)
    self.create_database()
    ssh.close()
