# Using GitLab CI/CD to deploy with AWS SAM
<a name="deploying-using-gitlab"></a>

To configure your [GitLab](https://about.gitlab.com) pipeline to automate the build and deployment of your AWS SAM application, your `gitlab-ci.yml` file must contain lines that do the following:

1. Reference a build container image with the necessary runtime from the available images. The following example uses the `public.ecr.aws/sam/build-nodejs20.x` build container image.

1. Configure the pipeline stages to run the necessary AWS SAM command line interface (CLI) commands. The following example runs two AWS SAM CLI commands: **sam build** and **sam deploy** (with necessary options).

This example assumes that you have declared all functions and layers in your AWS SAM template file with `runtime: nodejs20.x`.

```
image: public.ecr.aws/sam/build-nodejs20.x
deploy:
  script:
    - sam build
    - sam deploy --no-confirm-changeset --no-fail-on-empty-changeset
```
