[Challenge 1] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-1-script.html): Write a script that builds three 512 MB Cloud Servers that following a similar naming convention. (ie., web1, web2, web3) and returns the IP and login credentials for each server. Use any image you want. Worth 1 point

[Challenge 2] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-2-script_17.html): Write a script that clones a server (takes an image and deploys the image as a new server). Worth 2 Point

Challenge 3 : Write a script that accepts a directory as an argument as well as a container name. The script should upload the contents of the specified directory to the container (or create it if it doesn't exist). The script should handle errors appropriately. (Check for invalid paths, etc.) Worth 2 Points

[Challenge 4] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-4-script.html): Write a script that uses Cloud DNS to create a new A record when passed a FQDN and IP address as arguments. Worth 1 Point

[Challenge 5] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-5-script.html): Write a script that creates a Cloud Database instance. This instance should contain at least one database, and the database should have at least one user that can connect to it. Worth 1 Point

[Challenge 6] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-6-script.html): Write a script that creates a CDN-enabled container in Cloud Files. Worth 1 Point

[Challenge 7] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-7-script.html): Write a script that will create 2 Cloud Servers and add them as nodes to a new Cloud Load Balancer. Worth 3 Points

[Challenge 8] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-8-script.html): Write a script that will create a static webpage served out of Cloud Files. The script must create a new container, cdn enable it, enable it to serve an index file, create an index file object, upload the object to the container, and create a CNAME record pointing to the CDN URL of the container. Worth 3 Points

[Challenge 9] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-9-script.html): Write an application that when passed the arguments FQDN, image, and flavor it creates a server of the specified image and flavor with the same name as the fqdn, and creates a DNS entry for the fqdn pointing to the server's public IP. Worth 2 Points

[Challenge 10] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-10-script.html): Write an application that will:

• Create 2 servers, supplying a ssh key to be installed at /root/.ssh/authorized_keys.
• Create a load balancer
• Add the 2 new servers to the LB
• Set up LB monitor and custom error page.
• Create a DNS record based on a FQDN for the LB VIP.
• Write the error page html to a file in cloud files for backup. Whew! That one is worth 8 points!

[Challenge 11] (http://rtomaszewski.blogspot.co.uk/2013/04/challenge-11-script.html): Write an application that will: Create an SSL terminated load balancer (Create self-signed certificate.) Create a DNS record that should be pointed to the load balancer. Create Three servers as nodes behind the LB.

• Each server should have a CBS volume attached to it. (Size and type are irrelevant.)
• All three servers should have a private Cloud Network shared between them.
• Login information to all three servers returned in a readable format as the result of the script, including connection information. Worth 6 points

Challenge 12: Write an application that will create a route in mailgun so that when an email is sent to @apichallenges.mailgun.org it calls your Challenge 1 script that builds 3 servers.

Assumptions:

• Assume that challenge 1 can be kicked off by accessing (http://cldsrvr.com/challenge1). You just need to make sure that your message is getting posted to that URL

-Assume the Mailgun API key exists at ~/.mailgunapi. Assume no formatting, the api key will be the only data in the file.

Challenge 13: Write an application that nukes everything in your Cloud Account. It should:

• Delete all Cloud Servers
• Delete all Custom Images
• Delete all Cloud Files Containers and Objects
• Delete all Databases
• Delete all Networks
• Delete all CBS Volumes Worth 3 points
