#Go Hello World Overview

This app is a hello world plus a little big of basic functionality using Golang. The application uses Gin-Gonic for the app router and for templating.

Also check out a blog post on this topic as well for a more in depth look at Go and Gin-Gonic.

You can deploy your own instance of Go Hello World app to Bluemix. To do this, you can either use the Deploy to Bluemix button for an automated deployment or follow the step below to create and deploy your app manually.

1. Install Go. If you have Go installed skip to step 2.

2. Create a Bluemix Account

   Sign up for Bluemix or use an existing account.

3. Download and install the Cloud Foundry CLI tool

4. cd into the $GOPATH/src directory

cd $GOPATH/src

5. Clone the app to your local environment from your terminal using the following command:

git clone https://github.com/IBM-Bluemix/go-hello-world.git

6. cd into this newly created directory

cd go-hello-world

7. Compile the Go code:

$ make

8. Open the manifest.yml file and change the host value to something unique

The host you choose will determinate the subdomain of your application's URL: <host>.mybluemix.net

9. Connect to Bluemix in the command line tool and follow the prompts to log in:

$ cf api https://api.ng.bluemix.net
$ cf login

10. Deploy your app to Bluemix:

$ cf push

And voila! You now have your very own instance of the Go Hello World app running on Bluemix.

1. Install Go. If you have Go installed skip to step 2.

2. cd into the $GOPATH/src directory

cd $GOPATH/src

3. Clone the app to your local environment from your terminal using the following command:

git clone https://github.com/IBM-Bluemix/go-hello-world.git

4. cd into this newly created directory

cd go-hello-world

5. Compile the Go code:

Pull requests will be evaulated on an individual basis based on value add to the sample application.

The primary source of debugging information for your Bluemix app is the logs. To see them, run the following command using the Cloud Foundry CLI:

$ cf logs go-hello-world --recent

For more detailed information on troubleshooting your application, see the Troubleshooting section in the Bluemix documentation.

The go-hello-world sample web application includes code to track deployments to Bluemix and other Cloud Foundry platforms. The following information is sent to a Deployment Tracker service on each deployment:

• Application Name (application_name)
• Space ID (space_id)
• Application Version (application_version)
• Application URIs (application_uris)

This data is collected from the VCAP_APPLICATION environment variable in IBM Bluemix and other Cloud Foundry platforms. This data is used by IBM to track metrics around deployments of sample applications to IBM Bluemix. Only deployments of sample applications that include code to ping the Deployment Tracker service will be tracked.

To disable deployment tracking for this app remove the following 2 lines line 5 and line 13 in go-hello-world.go
