Using ssh to access instances

Using ssh to access instances

This section will show you how to ssh into an instance and set up the environment so you can run commands with manage.py

Setting up your ssh key

You will need to add your public SSH key to ssh_keys, located in the root folder of the SecondFunnel project.

If you do not have an SSH key, you'll need to create one.

To add your public SSH key, just run the following command:

cat ~/.ssh/id_rsa.pub >> ssh_keys 

The deployment process automatically appends ssh keys to the authorized keys file on the instance, which will allow you to SSH onto the machine.

Getting into an instance

In the AWS Console, go to the EC2 page (at the top of the screen: Services -> EC2), click instances on the left navigation bar, then click your instance. Find the instance's public DNS from the options pane that appears.

Now open a terminal and type in ssh ec2-user@<public_dns_from_above> You should now be on the instance.

Setting up the environment

Our code is stored in /opt/python/bundle/#/app/ where # is the highest numbered directory inside bundle (eg. /opt/python/bundle/7/app/). It's also linked from /opt/python/current/. Once in that directory:

cd /opt/python/current/app
source ../../../run/venv/bin/activate
source ../env

The first source is to setup the virtual environment, and the second sets up RDS environment variables. You can now run commands with manage.py.
