## Usage
|
|
|
|
### Docker Hub
|
|
|
|
To authenticate against [Docker Hub](https://hub.docker.com) it's strongly recommended to create a
|
|
[personal access token](https://docs.docker.com/docker-hub/access-tokens/) as an alternative to your password.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to Docker Hub
|
|
uses: docker/login-action@v2
|
|
with:
|
|
username: ${{ secrets.DOCKERHUB_USERNAME }}
|
|
password: ${{ secrets.DOCKERHUB_TOKEN }}
|
|
```
|
|
|
|
### GitHub Container Registry
|
|
|
|
To authenticate against the [GitHub Container Registry](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry),
|
|
use the [`GITHUB_TOKEN`](https://docs.github.com/en/actions/reference/authentication-in-a-workflow) for the best
|
|
security and experience.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to GitHub Container Registry
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: ghcr.io
|
|
username: ${{ github.actor }}
|
|
password: ${{ secrets.GITHUB_TOKEN }}
|
|
```
|
|
|
|
You may need to [manage write and read access of GitHub Actions](https://docs.github.com/en/packages/managing-github-packages-using-github-actions-workflows/publishing-and-installing-a-package-with-github-actions#upgrading-a-workflow-that-accesses-ghcrio)
|
|
for repositories in the container settings.
|
|
|
|
You can also use a [personal access token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
|
|
with the [appropriate scopes](https://docs.github.com/en/packages/getting-started-with-github-container-registry/migrating-to-github-container-registry-for-docker-images#authenticating-with-the-container-registry).
|
|
|
|
### GitLab
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|

|
[Create a service principal](https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auth-service-principal#create-a-service-principal)
|
|
with access to your container registry through the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
|
|
and take note of the generated service principal's ID (also called _client ID_) and password (also called _client secret_).
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|

|
|
> fully-managed service with support for both container images and non-container artifacts. If you currently use
|
|
> Google Container Registry, use the information [on this page](https://cloud.google.com/artifact-registry/docs/transition/transition-from-gcr)
|
|
> to learn about transitioning to Google Artifact Registry.
|
|
|
|
You can use either workload identity federation based keyless authentication or service account based authentication.
|
|
|
|
#### Workload identity federation based authentication
|
|
|
|
Configure the workload identity federation for github actions in gcloud (for steps, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation)). In the steps, your service account should the ability to push to GCR. Then use google-github-actions/auth action for authentication using workload identity like below:
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- id: 'auth'
|
|
name: 'Authenticate to Google Cloud'
|
|
uses: 'google-github-actions/auth@v0'
|
|
with:
|
|
token_format: 'access_token'
|
|
workload_identity_provider: '<workload_identity_provider>'
|
|
service_account: '<service_account>'
|
|
|
|
- name: Login to GCR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: gcr.io
|
|
username: oauth2accesstoken
|
|
password: ${{ steps.auth.outputs.access_token }}
|
|
```
|
|
|
|
> Replace `<workload_identity_provider>` with configured workload identity provider. For steps to configure, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation).
|
|
|
|
> Replace `<service_account>` with configured service account in workload identity provider which has access to push to GCR
|
|
|
|
#### Service account based authentication
|
|
|
|
Use a service account with the ability to push to GCR and [configure access control](https://cloud.google.com/container-registry/docs/access-control).
|
|
Then create and download the JSON key for this service account and save content of `.json` file
|
|
[as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
|
|
called `GCR_JSON_KEY` in your GitHub repo. Ensure you set the username to `_json_key`,
|
|
or `_json_key_base64` if you use a base64-encoded key.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to GCR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: gcr.io
|
|
username: _json_key
|
|
password: ${{ secrets.GCR_JSON_KEY }}
|
|
```
|
|
|
|
### Google Artifact Registry (GAR)
|
|
|
|
You can use either workload identity federation based keyless authentication or service account based authentication.
|
|
|
|
#### Workload identity federation based authentication
|
|
|
|
Configure the workload identity federation for github actions in gcloud (for steps, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation)). In the steps, your service account should the ability to push to GAR. Then use google-github-actions/auth action for authentication using workload identity like below:
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- id: 'auth'
|
|
name: 'Authenticate to Google Cloud'
|
|
uses: 'google-github-actions/auth@v0'
|
|
with:
|
|
token_format: 'access_token'
|
|
workload_identity_provider: '<workload_identity_provider>'
|
|
service_account: '<service_account>'
|
|
|
|
- name: Login to GAR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: <location>-docker.pkg.dev
|
|
username: oauth2accesstoken
|
|
password: ${{ steps.auth.outputs.access_token }}
|
|
```
|
|
> Replace `<workload_identity_provider>` with configured workload identity provider
|
|
|
|
> Replace `<service_account>` with configured service account in workload identity provider which has access to push to GCR
|
|
|
|
> Replace `<location>` with the regional or multi-regional [location](https://cloud.google.com/artifact-registry/docs/repo-organize#locations)
|
|
> of the repository where the image is stored.
|
|
|
|
#### Service account based authentication
|
|
|
|
Use a service account with the ability to push to GAR and [configure access control](https://cloud.google.com/artifact-registry/docs/access-control).
|
|
Then create and download the JSON key for this service account and save content of `.json` file
|
|
[as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
|
|
called `GAR_JSON_KEY` in your GitHub repo. Ensure you set the username to `_json_key`,
|
|
or `_json_key_base64` if you use a base64-encoded key.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to GAR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: <location>-docker.pkg.dev
|
|
username: _json_key
|
|
password: ${{ secrets.GAR_JSON_KEY }}
|
|
```
|
|
|
|
> Replace `<location>` with the regional or multi-regional [location](https://cloud.google.com/artifact-registry/docs/repo-organize#locations)
|
|
> of the repository where the image is stored.
|
|
|
|
### AWS Elastic Container Registry (ECR)
|
|
|
|
Use an IAM user with the ability to [push to ECR with `AmazonEC2ContainerRegistryPowerUser` managed policy for example](https://docs.aws.amazon.com/AmazonECR/latest/userguide/ecr_managed_policies.html#AmazonEC2ContainerRegistryPowerUser).
|
|
Then create and download access keys and save `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` [as secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
|
|
in your GitHub repo.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to ECR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
|
|
username: ${{ secrets.AWS_ACCESS_KEY_ID }}
|
|
password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
|
|
```
|
|
|
|
If you need to log in to Amazon ECR registries associated with other accounts, you can use the `AWS_ACCOUNT_IDS`
|
|
environment variable:
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:

|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Login to ECR
|
|
uses: docker/login-action@v2
|
|
with:
|
|
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
|
|
username: ${{ secrets.AWS_ACCESS_KEY_ID }}
|

password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
|
|
env:
|
|
AWS_ACCOUNT_IDS: 012345678910,023456789012
|
|
```
|
|
|
|
> Only available with [AWS CLI version 1](https://docs.aws.amazon.com/cli/latest/reference/ecr/get-login.html)
|
|
|
|
You can also use the [Configure AWS Credentials](https://github.com/aws-actions/configure-aws-credentials) action in
|
|
combination with this action:
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: main
|
|
|
|
jobs:
|
|
login:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Configure AWS Credentials
|
|
uses: aws-actions/configure-aws-credentials@v1
|
|
with:
|
|
aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
|
|
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
|
|
aws-region: <region>
|
|

|
|
Then create and download access keys and save `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` [as secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
|
|
in your GitHub repo.
|

## Keep up-to-date with GitHub Dependabot
|
|
|
|
Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
|
|
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
|
|
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
|
|
|
|
```yaml
|
|
version: 2
|
|
updates:
|
|
# Maintain dependencies for GitHub Actions
|
|
- package-ecosystem: "github-actions"
|
|
directory: "/"
|
|
schedule:
|
|
interval: "daily"
|
|
```
|
