- a [Matrix Synapse](https://github.com/matrix-org/synapse) homeserver - storing your data and managing your presence in the [Matrix](http://matrix.org/) network
- (optional) [Amazon S3](https://aws.amazon.com/s3/) storage for your Matrix Synapse's content repository (`media_store`) files using [s3fs-fuse](https://github.com/s3fs-fuse/s3fs-fuse)
- a [PostgreSQL](https://www.postgresql.org/) database for Matrix Synapse - providing better performance than the default [SQLite](https://sqlite.org/) database
- a [STUN server](https://github.com/coturn/coturn) for WebRTC audio/video calls
- a [STUN/TURN server](https://github.com/coturn/coturn) for WebRTC audio/video calls
- a [Riot](https://riot.im/) web UI
- a [Riot](https://riot.im/) web UI, which is configured to connect to your own Matrix Synapse server by default
- free [Let's Encrypt](https://letsencrypt.org/) SSL certificate, which secures the connection to the Synapse server and the Riot web UI

- this one retrieves and automatically renews free [Let's Encrypt](https://letsencrypt.org/) **SSL certificates** for you
- this one optionally can store the `media_store` content repository files on [Amazon S3](https://aws.amazon.com/s3/)

- edit the inventory hosts file (`inventory/hosts`) to your liking
## Amazon S3 configuration (optional)
If you'd like to store Matrix Synapse's content repository (`media_store`) files on Amazon S3,
you can let this playbook configure [s3fs-fuse](https://github.com/s3fs-fuse/s3fs-fuse) for you.
You'll need an Amazon S3 bucket and some IAM user credentials (access key + secret key) with full write access to the bucket. Example security policy:
```
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1400105486000",
"Effect": "Allow",
"Action": [
"s3:*"
],
"Resource": [
"arn:aws:s3:::your-bucket-name",
"arn:aws:s3:::your-bucket-name/*"
]
}
]
}
```
You then need to enable S3 support in your configuration file (`inventory/matrix.<your-domain>/vars.yml`).
It would be something like this:
```
matrix_s3_media_store_bucket_name: "your-bucket-name"
matrix_s3_media_store_aws_access_key: "access-key-goes-here"
matrix_s3_media_store_aws_secret_key: "secret-key-goes-here"
```
## Installing
Once you have your server and you have [configured your DNS records](#configuring-dns), you can proceed with installing.
