  7. (*.nix-only environments) Find the cd29.pem file on your computer (where 29 is your student id). If you are are a *nix-based computer, you will need to modify the permissions to 400.
    $ chmod 400 cd29.pem
    			
  8. From the directory where your cd29.pem (where 29 is your student id) is located, enter the command below to SSH into the utility instance. In the example below, modify PUBLIC_DNS to your the public DNS provided as a value when selecting Outputs tab for the AWSCLI CloudFormation template you created.
    $ ssh -i cd29.pem ec2-user@PUBLIC_DNS
    				
  9. Enter yes to the security prompt.

EXERCISE: Create an S3 bucket to host credentials

  1. Create a new S3 bucket and call it cd29creds (where 29 is your student id). Use https://console.aws.amazon.com/s3/home and click the Create Bucket button. IMPORTANT: Be sure to choose US Standard in the Region dropdown box.

EXERCISE: Create an S3 bucket to host artifacts

  1. Create a new S3 bucket and call it cd29artifacts (where 29 is your student id). Use https://console.aws.amazon.com/s3/home and click the Create Bucket button. IMPORTANT: Be sure to choose US Standard in the Region dropdown box.

  4. Go to https://github.com/stelligent/devopsinthecloud
  5. Click the Fork button. A message will display "Where do you want to fork this to?". Click on the button that says Fork to YOURUSERID.
  6. Go to https://github.com/stelligent/sample_app
  7. Click the Fork button. A message will display "Where do you want to fork this to?". Click on the button that says Fork to YOURUSERID.

  11. Click the Fork button. A message will display "Where do you want to fork this to?". Click on the button that says Fork to YOURUSERID.
  12. Create an SSH keypair by SSH'ing to the AWSCLI instance you created when launching the CloudFormation stack in the section above. In the example below, you will use the email address that's registered with your GitHub account. You can find yours by going to https://github.com/settings/profile/. Accept the defaults after running this command below. NOTE: Use your student id instead of 29. For example, student03@stelligent.com
    $ ssh-keygen -t rsa -C "student29@stelligent.com"
    			
  13. Display the contents of the public key and copy the contents to your clipboard.
    $ cat ~/.ssh/id_rsa.pub
    			
  14. After logging into your GitHub account, go to your GitHub SSH Keys settings at https://github.com/settings/ssh/. Click on the Add SSH Key button, give it a name and paste the contents of the public key into the Key text field. Then, click the Add key button. Enter your GitHub password when prompted.
  15. Go back to the AWS CLI instance, go to the root directory and type the following from the command line. Replace student29 with your GitHub userid.
    $ git clone git@github.com:student29/continuous_integration_example.git
    			
  16. Go back to the AWS CLI instance, go to the root directory and type the following from the command line. Replace student29 with your GitHub userid.

    $ git clone git@github.com:student29/ciexample_jenkins.git
    			
  20. From the home directory on the AWSCLI, type ls from the command prompt. You should see continuous_integration_example, devopsinthecloud, sample_app, devcenter-embedded-tomcat and ciexample_jenkins as subdirectories.

EXERCISE: Upload SSH keys

  1. Mac: Secure copy the SSH key files to your computer. Your Public DNS will be different. This example assumes you're installing to your Desktop folder on your Mac.
    scp -i cd29.pem ec2-user@PUBLIC_DNS:~/.ssh/id_rsa ~/Desktop
    scp -i cd29.pem ec2-user@PUBLIC_DNS:~/.ssh/id_rsa.pub ~/Desktop
    scp -i cd29.pem ec2-user@PUBLIC_DNS:~/.ssh/known_hosts ~/Desktop
    	
  2. Windows: Secure copy the SSH key files to your computer. Your Public DNS will be different. This example assumes that pscp.exe and cd29.ppk are installed at c:\putty. Modify the locations if yours are different.
    c:\putty\pscp.exe -i c:\putty\cd00.ppk ec2-user@PUBLIC_DNS:/home/ec2-user/.ssh/id_rsa c:\putty
    c:\putty\pscp.exe -i c:\putty\cd00.ppk ec2-user@PUBLIC_DNS:/home/ec2-user/.ssh/id_rsa.pub c:\putty
    c:\putty\pscp.exe -i c:\putty\cd00.ppk ec2-user@PUBLIC_DNS:/home/ec2-user/.ssh/known_hosts c:\putty
  3. In https://console.aws.amazon.com/s3/home, go to the bucket you created above (e.g. cd29creds).
  4. Click on the Upload button.
  5. Click Add Files and add the id_rsa, id_rsa.pub and known_hosts files from the commands above to the cd29creds S3 bucket (where 29 is your student id).
  6. Click Start Upload.
