# Building Continuous Delivery (CD) Pipelines
|
|
|
|
## Writing a Basic Jenkinsfile
|
|
|
|
1. Create a new GitHub repository named `go-on-jenkins`.
|
|
2. Create a new `Jenkinsfile` in the root directory of the repository as well as a simple `main.go` file. The main function just prints "Hello World!". Initialize the project via Go Modules.
|
|
3. Commit the files and push them to the remote repository.
|
|
4. Set up a new pipeline job for this repository in Jenkins.
|
|
5. Install the Jenkins Go plugin.
|
|
6. Configure the latest Go runtime as global tool.
|
|
7. Enhance the `Jenkinsfile` based on the following requirements. The Jenkinsfile should use the declarative syntax.
|
|
* The job can run on all agents.
|
|
* The job sets the environment variable `GO111MODULES=on`.
|
|
* The job uses the Go runtime from the global tool definition.
|
|
* The job specifies one build stage named "Build". The build stage executes the shell command `go build`.

|
|
|
Create a new job.
|
|
|
|
|
|
|
|
Configure the appropriate SCM.
|
|
|
|
|
|
|
|
Install the Go plugin.
|
|
|
|
|
|
|
|
Configure a Go runtime as global tool.
|
|
|
|
|
|
|
|
The final `Jenkinsfile` looks similar to the solution below.
|
|
|
|
```groovy
|
|
pipeline {
|
|
agent any
|
|
tools {
|
|
go 'go-1.12'
|
|
}
|
|
environment {
|
|
GO111MODULE = 'on'
|
|
}
|
|
stages {
|
|
stage('Build') {
|
|
steps {
|
|
sh 'go build'
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
A build of the job installs the Go runtime and executes the build step.
