Cookbook to provision a simple 2-tier Golang sample application.
This cookbook has been tested on the following platforms:
- Ubuntu 14.04
Include the go-app-configmanagement::default and go-app-configmanagement::nginx recipes in your nodes runlist to deploy the nginx reverse proxy:
{
"name": "web",
"run_list": [
"recipe[go-app-configmanagement::default]",
"recipe[go-app-configmanagement::nginx]"
]
}
Include the go-app-configmanagement::default and go-app-configmanagement::go_app recipes in your nodes runlist to deploy the Golang sample app:
{
"name": "app-XX",
"run_list": [
"recipe[go-app-configmanagement::default]",
"recipe[go-app-configmanagement::go_app]"
]
}
The following Tests are being used for this cookbook:
foodcriticandrubocopfor style checkingtest-kitchenfor integration testing
To manually invoke the tests, run bundle exec rake test.
The following requirements need to be satisfied for local testing:
- Vagrant
- VirtualBox
- Vagrant Bershelf Plugin
Circle CI has been set up to run continuous testing on this Repository. Integration testing it done using the kitchen-docker gem.
Code is 'deployed' via a remote_file resource that downloads the artifact from an S3 bucket. The artifact is uploaded to that bucket via a Job on Circle CI. While is not a perfect method for doing continuous deployments, it will certainly pick up any changes to the source code and make them available eventually:
$ nano main.go
<modifying source code>
$ git diff
diff --git a/main.go b/main.go

Due to my lack of familiarity with rspec I have not written any unit tests for this cookbook. This is certainly something I would recommend doing as a next step.
