Utilities for Amazon Elastic File System (EFS)

The `efs-utils` package has been verified against the following Linux distributions:

| Distribution | Package Type | `init` System |
| ------------ | ------------ | ------------- |
| Amazon Linux 2017.09 | `rpm` | `upstart` |
| Amazon Linux 2 | `rpm` | `systemd` |
| CentOS 7 | `rpm` | `systemd` |
| RHEL 7 | `rpm`| `systemd` |
| Debian 9 | `deb` | `systemd` |
| Ubuntu 16.04 | `deb` | `systemd` |

## Prerequisites

* `nfs-utils` (RHEL/CentOS/Amazon Linux) or `nfs-common` (Debian/Ubuntu)
* OpenSSL 1.0.2+
* Python 2.7+
* `stunnel` 4.56+

## Installation

### On Amazon Linux distributions

For those using Amazon Linux or Amazon Linux 2, the easiest way to install `efs-utils` is from Amazon's repositories:

```
$ sudo yum -y install amazon-efs-utils
```

### On other Linux distributions

Other distributions require building the package from source and installing it.

- Clone this repository:

```
$ git clone https://github.com/aws/efs-utils
$ cd efs-utils
```

- To build and install an RPM:

```
$ sudo yum -y install rpm-build
$ make rpm
$ sudo yum -y install build/amazon-efs-utils*rpm
```

- To build and install a Debian package:

```
$ sudo apt-get update
$ sudo apt-get -y install binutils
$ ./build-deb.sh
$ sudo apt-get -y install ./build/amazon-efs-utils*deb
```

#### Run tests

- [Set up a virtualenv](http://libzx.so/main/learning/2016/03/13/best-practice-for-virtualenv-and-git-repos.html) for efs-utils

```
$ virtualenv ~/.envs/efs-utils
$ source ~/.envs/efs-utils/bin/activate
$ pip install -r requirements.txt
```

- Run tests

```
$ make test
```

## Usage

### mount.efs

`efs-utils` includes a mount helper utility to simplify mounting and using EFS file systems.

To mount with the recommended default options, simply run:

```
$ sudo mount -t efs file-system-id efs-mount-point/
```

To mount automatically with recommended options, add an `/etc/fstab` entry like:

```
file-system-id efs-mount-point efs _netdev 0 0
```

To mount over TLS, simply add the `tls` option:

```
$ sudo mount -t efs -o tls file-system-id efs-mount-point/
```

To mount over TLS automatically, add an `/etc/fstab` entry like:

```
file-system-id efs-mount-point efs _netdev,tls 0 0
```

For more information on mounting with the mount helper, see the [documentation](https://docs.aws.amazon.com/efs/latest/ug/using-amazon-efs-utils.html).

#### amazon-efs-mount-watchdog

`efs-utils` contains a watchdog process to monitor the health of TLS mounts. This process is managed by either `upstart` or `systemd` depending on your Linux distribution, and is started automatically the first time an EFS file system is mounted over TLS.

## Upgrading stunnel for RHEL/CentOS

By default, when using the EFS mount helper with TLS, it enforces use of the Online Certificate Status Protocol (OCSP) and certificate hostname checking. The EFS mount helper uses the `stunnel` program for its TLS functionality. Please note that some versions of Linux do not include a version of `stunnel` that supports these TLS features by default. When using such a Linux version, mounting an EFS file system using TLS will fail.

Once you’ve installed the `amazon-efs-utils` package, to upgrade your system’s version of `stunnel`, see [Upgrading Stunnel](https://docs.aws.amazon.com/efs/latest/ug/using-amazon-efs-utils.html#upgrading-stunnel).
