This is an AWS CloudFormation stack written in Kumogata's Ruby DSL with an auto-scaling application running a small 'hello world' Go application deployed automatically with Chef.
There is a Chef cookbook in site-cookbooks called hw_goapp. This will automatically deploy any go application included in node['go']['packages'] and as an init file and run it under the username provided in node['go']['owner'].
bundle installto retrieve all dependencies- If you'd like to change the app that is deployed, edit node.json with the appropriate 'go get' source package.
- Make sure your app listens on port 8484!
kumogata create infrastructure.rb -r $REGION -p KeyName=$AWS_KEY_NAME[AppType=$APP_TYPE,AppGroupSize=$APP_SIZE,AppMaxSize=$APP_MAX_SIZE,SSHLocation=$SSH_CIDR,ChefRepoURL=$CHEF_REPOURL,ChefRepoBranch=$CHEF_REPOBRANCH,ChefRepo=$CHEF_REPO]
Optional parameters are in square brackets, refer to the list below for a description of each. Once this is complete, kumogata update can be used with the stack's name and aforementioned parameters to make changes or kumogata delete with the stack's name to remove it.
$REGION- AWS Region (eg. eu-west-1). Deployments are multi-AZ within EC2 (no VPC).$APP_TYPE- Size of the application instance. For a list of supported sizes, refer to infrastructure.rb (default m3.medium).$APP_SIZE- Default and preferred size of the auto-scaling group, in instances (default 1).$APP_MAX_SIZE- Maximum size of the autoscaling group, in instances (default 1).$SSH_CIDR- CIDR mask of the network from which you'll SSH. Default permits all IPs (0.0.0.0/0).$CHEF_REPOURL- The URL prefix of your repository (eg. the default is https://github.com/cvlc/)$CHEF_REPO- The name of the git repository that appears after the URL prefix (eg. hello_world)$CHEF_REPOBRANCH- The branch of the git repository (eg. master)
- Add cfn-hup hook so chef-solo is automatically triggered on updates (currently, you need to kick it on existing instances or rescale them)
- Automate DNS management with Route53
- Split out repositories for Chef, app, etc.
- Split out hw_goapp cookbook into it's own repository and genericize it.
- Support VPC configurations
- Add automatic scaling and alerting with Cloudwatch
- Add more possible instance types
- Add support for custom load-balancers (eg. nginx, vulcand)
- Integrate automatic route53 management
- Integrate into CI/CD systems like Jenkins/Bamboo
