Stalkedbybean

Little Ruby command line utility to help Ascential Makers to deploy on AWS beanstalk. Configurable through command line and config file.

Add this line to your application's Gemfile:

gem 'stalkedbybean'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install stalkedbybean

You can perform all the steps for deploying your app (initializing it, handling secrets, creating the environment, deploying the version and terminating environment finally) by running a simple Ruby script.

1. This gem relies on some dependencies (AWS CLI, AWS EB CLI and Credstash) you will have to install.

$ pip3 install awscli --upgrade --user
$ pip3 install awsebcli --upgrade --user
$ pip3 install boto botocore boto3
$ pip3 install credstash

2. Make sure you have your AWS credentials set up. If not, you can do so by following the instructions here.

3. Initialise a default config file in your project's root directory. Replace your-environment-name which whatever applies to you (eg; test, staging, production etc). This should generate a config file and config settings file in the directory you are in.

$ stalkedbybean init your-environment-name

4. Update the generated config file with the config options relevant to your app especially the mandatory ones for setting up secrets. You won't be able to get your kms_arn until you set up your secrets below so leave that for now.

Detailed information on how to update your config options can be found here.

5. The generated file will automatically be set as your default config file. You can override this by passing it with the flag -f FILENAME when running the gem commands or changing the default file in config/.stalkedbybean.yml.

stalkedbybean init                            # Generates a config file
stalkedbybean create [OPTIONS]                # Creates a new AWS application
stalkedbybean secrets <command> [OPTIONS]     # Sets up and manages secrets using Credstash
stalkedbybean setup_roles [OPTIONS]           # Sets up roles in AWS IAM
stalkedbybean provision -v VERSION [OPTIONS]  # Provisions new environment in AWS EB
stalkedbybean deploy -v VERSION [OPTIONS]     # Deploys new version of environment
stalkedbybean terminate [OPTIONS]             # Terminates environment, application and all resources
stalkedbybean update_config [OPTIONS]         # Updates all config options
stalkedbybean print_env_vars [OPTIONS]        # Prints existing environment variables
stalkedbybean update_env_vars [OPTIONS]       # Updates environment variables
stalkedbybean versions [OPTIONS]              # Displays application versions
stalkedbybean help [COMMAND]                  # Describe available commands or one specific command

The Beanstalk platform expects secrets to be put using CredStash, in the same region that you are deploying, using a table called your_app_name-your_environment_name, encrypted through a KMS key.

This can be done using stalkedbybeans.

1. Make sure you have the config.yml file with the mandatory options for setting up secrets filled up correctly.

2. Create a KMS key and setup a table to hold your secrets. This step will also print out your KMS ARN which you should copy and paste into your config.yml file as it will be required for deployment.

$ stalkedbybeans secrets setup

3. To add a secret in a key/value pair:

$ stalkedbybeans secrets add [key] [value]

4. To get a secret:

$ stalkedbybeans secrets get [key]

5. You can also change the value of an existing secret by creating a new version of it. Credstash will automatically use the latest version of the secret.

$ stalkedbybeans secrets change [key] [new_value] [version]

6. To get all the secrets stored within your application:

$ stalkedbybeans secrets getall

If you do not want to use the script, you can also use Credstash manually as described here.

Keys are versioned. See CredStash documentation for more details.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run rake features for the cucumber test. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
