Specify two runtimes

You can specify more than one runtime in the same CodeBuild build project. This sample project uses two source files: one that uses the Go runtime and one that uses the Node.js runtime.

1. Create a directory named my-source.

2. Inside the my-source directory, create a directory named golang-app.

3. Create a file named hello.go with the following contents. Store the file in the golang-app directory.

   package main
   import "fmt"
   
   func main() {
     fmt.Println("hello world from golang")
     fmt.Println("1+1 =", 1+1)
     fmt.Println("7.0/3.0 =", 7.0/3.0)
     fmt.Println(true && false)
     fmt.Println(true || false)
     fmt.Println(!true)
     fmt.Println("good bye from golang")
   }

4. Inside the my-source directory, create a directory named nodejs-app. It should be at the same level as the golang-app directory.

5. Create a file named index.js with the following contents. Store the file in the nodejs-app directory.

   console.log("hello world from nodejs");
   console.log("1+1 =" + (1+1));
   console.log("7.0/3.0 =" + 7.0/3.0);
   console.log(true && false);
   console.log(true || false);
   console.log(!true);
   console.log("good bye from nodejs");

6. Create a file named package.json with the following contents. Store the file in the nodejs-app directory.

   {
     "name": "mycompany-app",
     "version": "1.0.0",
     "description": "",
     "main": "index.js",
     "scripts": {
       "test": "echo \"run some tests here\""
     },
     "author": "",
     "license": "ISC"
   }

7. Create a file named buildspec.yml with the following contents. Store the file in the my-source directory, at the same level as the nodejs-app and golang-app directories. The runtime-versions section specifies the Node.js version 12 and Go version 1.13 runtimes.

   version: 0.2
   
   phases:
     install:
       runtime-versions:
         golang: 1.13
         nodejs: 12
     build:
       commands:
         - echo Building the Go code...
         - cd $CODEBUILD_SRC_DIR/golang-app
         - go build hello.go 
         - echo Building the Node code...
         - cd $CODEBUILD_SRC_DIR/nodejs-app
         - npm run test
   artifacts:
     secondary-artifacts:
       golang_artifacts:
         base-directory: golang-app
         files:
           - hello
       nodejs_artifacts:
         base-directory: nodejs-app
         files:
           - index.js
           - package.json

8. Your file structure should now look like this.

   my-source
   ├── golang-app
   │   └── hello.go
   ├── nodejs.app
   │   ├── index.js
   │   └── package.json
   └── buildspec.yml

9. Upload the contents of the my-source directory to an S3 input bucket or a CodeCommit, GitHub, or Bitbucket repository.

   Important

   If you are using an S3 input bucket, be sure to create a ZIP file that contains the directory structure and files, and then upload it to the input bucket. Do not add my-source to the ZIP file, just the directories and files in my-source.

10. Open the AWS CodeBuild console at https://console.aws.amazon.com/codesuite/codebuild/home.

11. Create a build project. For more information, see Create a build project (console) and Run a build (console). Leave all settings at their default values, except for these settings.

    • For Environment:

      • For Environment image, choose Managed image.

      • For Operating system, choose Amazon Linux 2.

      • For Runtime(s), choose Standard.

      • For Image, choose aws/codebuild/amazonlinux-x86_64-standard:4.0.

12. Choose Create build project.

13. Choose Start build.

14. On Build configuration, accept the defaults, and then choose Start build.

15. After the build is complete, view the build output on the Build logs tab. You should see output similar to the following. It shows output from the Go and Node.js runtimes. It also shows output from the Go and Node.js applications.
