### Amazon Web service variant
This variant use the OIDC and [AWS STS](https://docs.aws.amazon.com/fr_fr/STS/latest/APIReference/welcome.html) in AWS to get credential
#### Prerequesite
- [Create an OpenID Connect (OIDC) identity provider in IAM
](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_oidc.html)
- [Configure a web identity role](https://docs.gitlab.com/ee/ci/cloud_services/aws/#configure-a-role-and-trust)
#### Configuration
The image from alpine `k8s` is required for the use of aws-iam-authenticator.
The variant requires the additional configuration parameters :
| Input / Variable | Description | Default value |
|-----------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------|
| `aws-oidc-aud` / `AWS_OIDC_AUD` | The `aud` claim for the JWT token | `$CI_SERVER_URL` |
| `aws-oidc-role-arn` / `AWS_OIDC_ROLE_ARN` | Default IAM Role ARN associated with GitLab to [authenticate using OpenID Connect](https://docs.gitlab.com/ee/ci/cloud_services/aws/) | _none_ |
| `aws-review-oidc-role-arn` / `AWS_REVIEW_OIDC_ROLE_ARN` | IAM Role ARN associated with GitLab to [authenticate using OpenID Connect](https://docs.gitlab.com/ee/ci/cloud_services/aws/) on `review` env _(only define to override default)_ | _none_ |
| `aws-integ-oidc-role-arn` / `AWS_INTEG_OIDC_ROLE_ARN` | IAM Role ARN associated with GitLab to [authenticate using OpenID Connect](https://docs.gitlab.com/ee/ci/cloud_services/aws/) on `integration` env _(only define to override default)_ | _none_ |
| `aws-staging-oidc-role-arn` / `AWS_STAGING_OIDC_ROLE_ARN` | IAM Role ARN associated with GitLab to [authenticate using OpenID Connect](https://docs.gitlab.com/ee/ci/cloud_services/aws/) on `staging` env _(only define to override default)_ | _none_ |
| `aws-prod-oidc-role-arn` / `AWS_PROD_OIDC_ROLE_ARN` | IAM Role ARN associated with GitLab to [authenticate using OpenID Connect](https://docs.gitlab.com/ee/ci/cloud_services/aws/) on `production` env _(only define to override default)_ | _none_ |
| `kubectl-image` / `K8S_KUBECTL_IMAGE` | The Docker image used to run Kubernetes `kubectl` commands on [AWS] | `docker.io/alpine/k8s:1.32.1` |
#### Example
With a common default `AWS_OIDC_ROLE_ARN` configuration for non-prod environments, and a specific one for production:
```yaml
include:
# main template
- component: $CI_SERVER_FQDN/to-be-continuous/kubernetes/gitlab-ci-k8s@7.1.1
# AWS variant
- component: $CI_SERVER_FQDN/to-be-continuous/kubernetes/gitlab-ci-k8s-aws@7.1.1
inputs:
# common OIDC config for non-prod envs
aws-oidc-role-arn: "arn:aws:iam::<project_id>:role/<role_name>"
# specific OIDC config for prod
aws-prod-oidc-role-arn: "arn:aws:iam::<project_id>:role/<role_name>"
```
