## Usage
### DockerHub
```yaml
name: ci
on:
push:
branches: master
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Login to DockerHub
uses: crazy-max/ghaction-docker-login@v1
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_PASSWORD }}
```
### GitHub Package Registry
```yaml
name: ci
on:
push:
branches: master
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Login to GitHub Package Registry
uses: crazy-max/ghaction-docker-login@v1
with:
registry: docker.pkg.github.com
username: ${{ github.repository_owner }}
password: ${{ secrets.GITHUB_TOKEN }}
```
### GitLab
```yaml
name: ci
on:
push:
branches: master
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Login to GitLab
uses: crazy-max/ghaction-docker-login@v1
with:
registry: registry.gitlab.com
username: ${{ secrets.GITLAB_USERNAME }}
password: ${{ secrets.GITLAB_PASSWORD }}
```
### Google Container Registry (GCR)
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`.
```yaml
name: ci
on:
push:
branches: master
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Login to GCR
uses: crazy-max/ghaction-docker-login@v1
with:
registry: gcr.io
username: _json_key
password: ${{ secrets.GCR_JSON_KEY }}
```
### AWS Elastic Container Registry (ECR)
Use an IAM user with the [ability to push to ECR](https://docs.aws.amazon.com/AmazonECR/latest/userguide/ecr_managed_policies.html).
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: master
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Login to ECR
uses: crazy-max/ghaction-docker-login@v1
with:
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
username: ${{ secrets.AWS_ACCESS_KEY_ID }}
password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
```
> Replace `<aws-account-number>` and `<region>` with their respective values.
## Customizing
### inputs
Following inputs can be used as `step.with` keys
| Name | Type | Default | Description |
|------------------|---------|-----------------------------|------------------------------------|
| `registry` | String | | Server address of Docker registry. If not set then will default to Docker Hub |
| `username` | String | | Username used to log against the Docker registry |
| `password` | String | | Password or personal access token used to log against the Docker registry |
| `logout` | Bool | `true` | Log out from the Docker registry at the end of a job |
## 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"
```
## Limitation
This action is only available for Linux [virtual environments](https://help.github.com/en/articles/virtual-environments-for-github-actions#supported-virtual-environments-and-hardware-resources).
