## Introduction
This GitHub Action starts a Redis server on the default port `6379`.

This is useful when running tests against a Redis database.


## Usage
A code example says more than a 1000 words. Here’s an exemplary GitHub Action using a Redis server in versions 4 and 5 to test a Node.js app:

```yaml
name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x, 16.x, 18.x]
        redis-version: [4, 5, 6]

    steps:
    - name: Git checkout
      uses: actions/checkout@v2

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v1
      with:
        node-version: ${{ matrix.node-version }}

    - name: Start Redis
      uses: supercharge/redis-github-action@1.5.0
      with:
        redis-version: ${{ matrix.redis-version }}

    - run: npm install

    - run: npm test
      env:
        CI: true
```


### Using a Custom Redis Image
You can utilize an alternative Redis image using the `redis-image` input:

```yaml
name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        redis-version: [6.2.4-v4, 6.2.6-v3]

    steps:
    - name: Start Redis
      uses: supercharge/redis-github-action@1.5.0
      with:
        redis-image: redis/redis-stack-server
        redis-version: ${{ matrix.redis-version }}

    - name: …
```


### Using Redis on a Custom Port
You can start the Redis instance on a custom port using the `redis-port` input:

```yaml
name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        redis-version: [4, 5, 6]

    steps:
    - name: Start Redis
      uses: supercharge/redis-github-action@1.5.0
      with:
        redis-version: ${{ matrix.redis-version }}
        redis-port: 12345

    - name: …
```


### Using a Custom Container Name
This GitHub Action provides a Redis Docker container. The default container name is `redis`. It can be helpful to customize the container name. For example, when running multiple Redis instances in parallel. You can customize the container name using the `redis-container-name` input:

```yaml
name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        redis-version: [4, 5, 6]

    steps:
    - name: Start Redis
      uses: supercharge/redis-github-action@1.5.0
      with:
        redis-version: ${{ matrix.redis-version }}
        redis-container-name: redis-auth-token-cache

    - name: …
```

### Remove container when exit
Starting v1.6.0, when running this action on a self-hosted runner, it's helpful to remove the container so its name won't conflict:

```yaml
name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        redis-version: [4, 5, 6]

    steps:
    - name: Start Redis
      uses: supercharge/redis-github-action@1.6.0
      with:
        redis-version: ${{ matrix.redis-version }}
        redis-remove-container: true # false by default

    - name: …
```
