Pull code onto Pi

Retreive SSH key

Method 1 (Currently used): One private key for every Pi

This method can be automated, though may cause security risks as all Pis will be sharing the same private SSH key.

Get the private SSH key from Richard.

Login to Pi.

Check for existing SSH keys:

ls ~/.ssh

If the directory ".ssh" does not exist, create it with:

sudo mkdir .ssh

Copy the private SSH key into the ~/.ssh/id_rsa file. If the id_rsa file does not exist, create it with:

sudo touch id_rsa

If you see files named id_rsa.pub or id_dsa.pub you have keys set up already.

Method 2 (To be used in future): One SSH key per Pi

This is the correct way to pull code onto each Pi, though we will need to figure out how to do this. There is currently no way to automate this method.

Generate a SSH key

Login to Pi.

Open command line and generate key with command:

ssh-keygen -t rsa

Enter file in which to save the key (/home/pi/.ssh/id_rsa): Press Enter  
Created directory '/home/pi/.ssh'.

Enter passphrase (empty for no passphrase): Press Enter
Enter same passphrase again: Press Enter
Your identification has been saved in /home/pi/.ssh/id_rsa.
Your public key has been saved in /home/pi/.ssh/id_rsa.pub.

A key fingerprint and the key's randomart image will also be generated.

Add SSH key to GitLab

http://doc.gitlab.com/ce/gitlab-basics/create-your-ssh-keys.html

Clone envmonitor repo

cd to where the repo is to be placed.

Make sure you are connected to Spark's internal network:

ping gitlab.telecom.tcnz.net

If packets cannot be received, connect to the internal network before continuing.

Clone the repo:

git clone [email protected]:automation/envmonitor.git

If the line comes up:

The authenticity of host 'gitlab.telecom.tcnz.net (10.XXX.XXX.XXX)' can't be established.

Continue by typing 'yes'

The repo will then be cloned.
