To get started, we'll take you through a sample Go hello world app, help you set up a development environment and deploy to IBM Cloud.
The following instructions are for deploying the application as a Cloud Foundry application. To deploy as a container to IBM Cloud Kubernetes Service instead, see README-kubernetes.md
You'll need the following:
Now you're ready to start working with the simple Go hello world app. Clone the repository and change to the directory where the sample app is located.
git clone https://github.com/IBM-Cloud/get-started-go
cd get-started-go
Peruse the files in the get-started-go directory to familiarize yourself with the contents.
Build and run the app.
go run get-started-go.go
View your app at: http://localhost:8080
To deploy to IBM Cloud, it can be helpful to set up a manifest.yml file. One is provided for you with the sample. Take a moment to look at it.
The manifest.yml includes basic information about your app, such as the name, how much memory to allocate for each instance and the route. In this manifest.yml random-route: true generates a random route for your app to prevent your route from colliding with others. You can replace random-route: true with host: myChosenHostName, supplying a host name of your choice. Learn more...
applications:
- name: GetStartedGo
random-route: true
memory: 128M
You can use the IBM Cloud CLI to deploy apps.
ibmcloud login
ibmcloud target --cf
From within the get-started-go directory push your app to IBM Cloud
ibmcloud cf push
This can take a minute. If there is an error in the deployment process you can use the command ibmcloud cf logs <Your-App-Name> --recent to troubleshoot.
When deployment completes you should see a message indicating that your app is running. View your app at the URL listed in the output of the push command. You can also issue the
ibmcloud cf apps
command to view your apps status and see the URL.
