Getting Started with Fli: Using AWS CloudFormation

Fli is a command line interface that you can use to deploy a stack with CloudFormation and snapshot, clone, push, and pull data volumes to FlockerHub.

This blog post will walk you through using a CloudFormation template that we have provided to help you easily get started using Fli on AWS. We will take 10-15 minutes to download the template, create our CloudFormation in AWS Console, log in to our newly created Fli client and start using Fli.

Prerequisites

Video Walkthrough

Step-by-Step Tutorial

Overall, you will take the following steps to complete this tutorial:

  • Go to the Amazon CloudFormation Console.
  • Click Create Stack
  • Choose “Upload a template”, and then choose the fli-CloudFormation-Ubuntu16.04 template from this repository.
  • Click Next
  • Choose your SSH Key and give your Stack a name.
  • Click Create to start the Stack.

Download the Pre-Baked CloudFormation Template

git clone https://github.com/ClusterHQ/examples
cd example/fli-cloudformation
ls fli-cloudformation/
README.md                       fli-CloudFormation-Ubuntu16.04


Log Into AWS CloudFormation

CF Dash

Next, click Create Stack in the top left.

Set Up the Template and Deploy Your Stack

Choose the template from the examples repository.

Choose CF Tempalte


You will use the Upload a template to Amazon S3.

Before Next CF Dash


Click Next, then enter a Stack name and an SSH Key.

Add CF Temp Info


Then click Next, Next, Create and wait for your Fli client to boot up.

SSH to Your New Machine and Start Using Fli!

Now that your CloudFormation template is complete, you can find the DNS name of your server in the outputs tab of your CloudFormation stack.

Stack Outputs

ssh -i ~/yourkey.pem ubunutu@<DNS-NAME-FROM-CLOUDFORMATION-OUTPUT>
sudo su
fli setup --zpool chq 
fli init MyFirstVolumeset -a owner=me,env=vagrant -d "My first volumeset for snapshots!"
fli create MyFirstVolumeset my-first-volume -a first_volume=true fli snapshot MyFirstVolumeset:my-first-volume MySnapshot

Sync and Push Your New Volumeset and Snapshot!

First, you need a token.

In order to receive a token, sign up for FlockerHub and visit the token creation settings page to create your new token.

Copy the contents of the authentication token file token.txt to a file in your new machine.

The authentication token can be created by navigating to your settings in FlockerHub. Also, make sure to place it in /root/ because Fli is set up in this guide to run as a container with the /root/ directory mapped in as a volume. You can change the alias and volume in .bashrc if you desire.

$ vi /root/my.token # (type `i` then paste the token, then hit `esc`, then type `:wq!` then hit RETURN)

Once your token is on the machine, use it to configure Fli.

$ fli config --token /root/my.token

Then, you can sync and push your data!

$ fli sync MyFirstVolumeset
$ fli push MyFirstVolumeset:MySnapshot


Visit your volumesets page to see your newly created volumeset.

Notes About the Environment

This environment above only provisions a 100GB EBS volume to support Fli. The alloted free amount with new FlockerHub accounts is 5GB. If you wish to use more data than this, email

You can optionally edit the CloudFormation template where the size of the volume is set, in the type AWS::EC2::Volume where it currently is set for "Size" : "100",. You may edit this to be larger or as small at 1GB, which is the minimum AWS allows.

"EBSVolume": { "Type":"AWS::EC2::Volume", "Properties" : { "AvailabilityZone" : { "Fn::GetAtt" : [ "EC2Instance", "AvailabilityZone" ] }, "Encrypted" : "true", "Size" : "100", "Tags" : [ { "Key" : "Fli", "Value" : "EC2 Node" } ] }, "DeletionPolicy" : "Snapshot" }, "MountPoint" : { "Type" : "AWS::EC2::VolumeAttachment", "Properties" : { "InstanceId" : { "Ref" : "EC2Instance" }, "VolumeId" : { "Ref" : "EBSVolume" }, "Device" : "/dev/sdf" } },


Clean Up / Refresh the Environment

To refresh the environment, destroy your stack from the CloudFormation console.

Delete Stack


Then, go through the above steps again to create a fresh, new Fli client.

Conclusion

We hope this was useful! We will continue to post new blogs in this series, as well as use cases for Fli and FlockerHub. Stay tuned!
