# volumizr

[![Build Status](https://travis-ci.org/TheNatureOfSoftware/volumizr.svg?branch=master)](https://travis-ci.org/TheNatureOfSoftware/volumizr)

This is a simple (simplistic or poor but not necessarily bad) solution for solving storage in a Kubernetes cluster. The solution uses `emptyDir` volumes in `StatefulSet` and `init-containers` for setting up volumes before start by mirroring from a [Minio](https://minio.io) server, and after start continuously mirrors changes back.

## Usage

### Mirror in

Docker:

```

$ docker run --rm -it -v $PWD/config.json:/app/config/config.json -v $PWD/mydata:/app/target thenatureofsoftware/volumizr in minio/bucket1 /app/target

```

Init container in Kubernetes:

```

annotations:

  pod.beta.kubernetes.io/init-containers:

    '[{

    "name": "volumizr-in",

    "image": "thenatureofsoftware/volumizr:latest",

    "args": ["in", "minio/mysql", "/var/lib/mysql"],

    "volumeMounts": [{

      "mountPath": "/var/lib/mysql",

      "name": "persistentdata"

    }]

  }]

```

### Mirror out

For continuously mirror changes back to minio server.

Docker:

```

$ docker run --rm -it -v $PWD/config.json:/app/config/config.json -v $PWD/mydata:/app/source thenatureofsoftware/volumizr out /app/source minio/bucket1

```

As a sidecar container in Kubernetes:

```

...

- image: thenatureofsoftware/volumizr:latest

  imagePullPolicy: Always

  name: volumizr-out

  args:

  - out

  - /var/lib/mysql

  - minio/mysql

  volumeMounts:

  - mountPath: "/var/lib/mysql"

    name: persistentdata

...

```
