## System requirements

In order to run Dockest, there's a few system requirements:

- Dockest uses Jest's programmatic CLI and requires Jest **v20.0.0** or newer to work
- [Docker](https://www.docker.com/)
- [Docker Compose](https://docs.docker.com/compose/install/) (_"On desktop systems like Docker Desktop for Mac and
  Windows, Docker Compose is included as part of those desktop installs."_)

---

## Install

```bash
yarn add --dev dockest

---

# docker-compose.yml
version: '3.8'

services:
  myRedis:
    image: redis:5.0.3-alpine
    ports:
      - published: 6379
        target: 6379
```

```ts
// dockest.ts
import { Dockest } from 'dockest';

const dockest = new Dockest();

// Specify the services from the Compose file that should be included in the integration test
const dockestServices = [
  {
    serviceName: 'myRedis', // Must match a service in the Compose file
  },
];

dockest.run(dockestServices);
```

---

# docker-compose.yml
version: '3.8'

services:
  postgres: # (1)
    image: postgres:9.6-alpine
    ports:
      - published: 5432
        target: 5432
    environment: # (2)
      POSTGRES_DB: baby
      POSTGRES_USER: dont
      POSTGRES_PASSWORD: hurtme
```

```ts
// dockest.ts
import { Dockest } from 'dockest';

const { run } = new Dockest();

run([
  {
    serviceName: 'postgres', // must match (1)
    readinessCheck: async ({
      defaultReadinessChecks: { postgres },
      dockerComposeFileService: {
        environment: { POSTGRES_DB, POSTGRES_USER }, // must match (2)
      },
    }) => postgres({ POSTGRES_DB, POSTGRES_USER }),
  },
]);
```

#### `defaultReadinessChecks.redis`

The default readiness check for Redis is based on this [image](https://hub.docker.com/_/postgres) which is
plug-and-play.

```yaml

---

# docker-compose.yml
version: '3.8'

services:
  redis: # (1)
    image: redis:5.0.3-alpine
    ports:
      - published: 6379
        target: 6379
```

```ts
// dockest.ts
import { Dockest } from 'dockest';

const { run } = new Dockest();

run([
  {
    serviceName: 'redis', // must match (1)
    readinessCheck: ({ defaultReadinessChecks: { redis } }) => redis(),
  },
]);
```

#### `defaultReadinessChecks.web` [WIP]

Requires [wget](https://www.gnu.org/software/wget/). The image would most likely be a self-built web service.

The exact use case should be fleshed out.

```ts
// dockest.ts
import { Dockest } from 'dockest';

const { run } = new Dockest();

run([
  {
    serviceName: 'web', // must match (1)
    readinessCheck: async ({ defaultReadinessChecks: { web } }) => web(),
  },
]);
```
