sceptre DevOps Meetup

Slides from the Wroclaw Devops Meetup presentation and sample sceptre projects

• Sceptre GitHub project

• Sceptre documentation

How to run the presentation?

Install reveal-md using npm:

npm install -g reveal-md

Run:

reveal-md presentation/rule_the_aws.md

How to use the example projects?

The easiest way to take advantage of the examples is to use Vagrant. This will allow you to play with sceptre without the risk of altering your current computer setup.

Once installed, simply run vagrant up followed by vagrant ssh to access the Vagrant VM.

You will also need AWS access credentials. If you just want to play with the provided examples, the best way is to simply spin up the attached cloudformation template inside a sandbox account (you can create one using AWS Organizations). It will create a sceptre user with the required permissions. The access key id and the secret access key will be available in the stack outputs. Note: the permissions there are too strict for real-world sceptre usage..

Inside the Vagrant VM create a file ~/.aws/config with your credentials:

[profile sceptre_sandbox]
aws_access_key_id = AKIA...
aws_secret_access_key = OwQ...

Then navigate to either /vagrant/v1 or /vagrant/v2 for examples for sceptre v1 and v2 respectively.

Once there, run: pipenv shell followed by pipenv install to setup the virtual environment with the appropriate sceptre version.

Now you can easily play with the provided sceptre projects!

For instance:

vagrant@ubuntu-bionic:~$ cd /vagrant/v1
vagrant@ubuntu-bionic:/vagrant/v1$ pipenv shell
