To create a buildspec.yml file for our aws-code-pipeline microservice, perform the following instructions:

1. Open the VS Code IDE, click File | New File, name the file buildspec.yml, and save the file:

Figure 8.17 – VS Code create new buildspec.yml file

2. Add the following code to the buildspec.yml file and click File | Save. In this file, we are installing corretto11 Java for compiling our source code in the install phase, and in the pre_build phase we just print the Java version, although in a more complex application, we could do many more things.

   phases:
     install:
       runtime-versions:
         java: corretto11
