Available runtimes
You can specify one or more runtimes in the runtime-versions section of your buildspec file. If your runtime
is dependent upon another runtime, you can also specify its dependent runtime in the buildspec file.
If you do not specify any runtimes in the buildspec file, CodeBuild chooses the default runtimes that
are available in the image you use. If you specify one or more runtimes, CodeBuild uses only those runtimes.
If a dependent runtime is not specified, CodeBuild attempts to choose the dependent runtime for you.
Note
If a runtime version is not specified, CodeBuild uses the default version. The default version can change when a previously default version reaches end of life (EOL). To avoid unexpected changes to the build environment, we recommend specifying a runtime version in the buildspec file.
For more information, see Specify runtime versions in the buildspec file.
