# Installing Synapse
## Installing from source
(Prebuilt packages are available for some platforms - see [Prebuilt packages](#prebuilt-packages).)
System requirements:
- POSIX-compliant system (tested on Linux & OS X)
- Python 3.5, 3.6, 3.7, or 2.7
- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
Synapse is written in Python but some of the libraries it uses are written in
C. So before we can install Synapse itself we need a working C compiler and the
header files for Python C extensions. See [Platform-Specific
Instructions](#platform-specific-instructions) for information on installing
these on various platforms.
To install the Synapse homeserver run:
```
mkdir -p ~/synapse
virtualenv -p python3 ~/synapse/env
source ~/synapse/env/bin/activate
pip install --upgrade pip
pip install --upgrade setuptools
pip install matrix-synapse[all]
```
This will download Synapse from [PyPI](https://pypi.org/project/matrix-synapse)
and install it, along with the python libraries it uses, into a virtual environment
under `~/synapse/env`. Feel free to pick a different directory if you
prefer.
This Synapse installation can then be later upgraded by using pip again with the
update flag:
```
source ~/synapse/env/bin/activate
pip install -U matrix-synapse[all]
```
Before you can start Synapse, you will need to generate a configuration
file. To do this, run (in your virtualenv, as before)::
```
cd ~/synapse
python -m synapse.app.homeserver \
--server-name my.domain.name \
--config-path homeserver.yaml \
--generate-config \
--report-stats=[yes|no]
```
... substituting an appropriate value for `--server-name`. The server name
determines the "domain" part of user-ids for users on your server: these will
all be of the format `@user:my.domain.name`. It also determines how other
matrix servers will reach yours for Federation. For a test configuration,
set this to the hostname of your server. For a more production-ready setup, you
will probably want to specify your domain (`example.com`) rather than a
matrix-specific hostname here (in the same way that your email address is
probably `user@example.com` rather than `user@email.example.com`) - but
doing so may require more advanced setup. - see [Setting up Federation](README.rst#setting-up-federation). Beware that the server name cannot be changed later.
This command will generate you a config file that you can then customise, but it will
also generate a set of keys for you. These keys will allow your Home Server to
identify itself to other Home Servers, so don't lose or delete them. It would be
wise to back them up somewhere safe. (If, for whatever reason, you do need to
change your Home Server's keys, you may find that other Home Servers have the
old key cached. If you update the signing key, you should change the name of the
key in the `<server name>.signing.key` file (the second word) to something
different. See the
[spec](https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys)
for more information on key management.)
You will need to give Synapse a TLS certficate before it will start - see [TLS
certificates](#tls-certificates).
To actually run your new homeserver, pick a working directory for Synapse to
run (e.g. `~/synapse`), and::
cd ~/synapse
source env/bin/activate
synctl start
### Platform-Specific Instructions
#### Debian/Ubuntu/Raspbian
Installing prerequisites on Ubuntu or Debian:
```
sudo apt-get install build-essential python3-dev libffi-dev \
python-pip python-setuptools sqlite3 \
libssl-dev python-virtualenv libjpeg-dev libxslt1-dev
```
#### ArchLinux
Installing prerequisites on ArchLinux:
```
sudo pacman -S base-devel python python-pip \
python-setuptools python-virtualenv sqlite3
```
#### CentOS/Fedora
Installing prerequisites on CentOS 7 or Fedora 25:
```
sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
lcms2-devel libwebp-devel tcl-devel tk-devel redhat-rpm-config \
python-virtualenv libffi-devel openssl-devel
sudo yum groupinstall "Development Tools"
```
#### Mac OS X
Installing prerequisites on Mac OS X:
```
xcode-select --install
sudo easy_install pip
sudo pip install virtualenv
brew install pkg-config libffi
```
#### OpenSUSE
Installing prerequisites on openSUSE:
```
sudo zypper in -t pattern devel_basis
sudo zypper in python-pip python-setuptools sqlite3 python-virtualenv \
python-devel libffi-devel libopenssl-devel libjpeg62-devel
```
#### OpenBSD
Installing prerequisites on OpenBSD:
```
doas pkg_add python libffi py-pip py-setuptools sqlite3 py-virtualenv \
libxslt jpeg
```
There is currently no port for OpenBSD. Additionally, OpenBSD's security
settings require a slightly more difficult installation process.
XXX: I suspect this is out of date.
1. Create a new directory in `/usr/local` called `_synapse`. Also, create a
new user called `_synapse` and set that directory as the new user's home.
This is required because, by default, OpenBSD only allows binaries which need
write and execute permissions on the same memory space to be run from
`/usr/local`.
2. `su` to the new `_synapse` user and change to their home directory.
3. Create a new virtualenv: `virtualenv -p python2.7 ~/.synapse`
4. Source the virtualenv configuration located at
`/usr/local/_synapse/.synapse/bin/activate`. This is done in `ksh` by
using the `.` command, rather than `bash`'s `source`.
5. Optionally, use `pip` to install `lxml`, which Synapse needs to parse
webpages for their titles.
6. Use `pip` to install this repository: `pip install matrix-synapse`
7. Optionally, change `_synapse`'s shell to `/bin/false` to reduce the
chance of a compromised Synapse server being used to take over your box.
After this, you may proceed with the rest of the install directions.
#### Windows
If you wish to run or develop Synapse on Windows, the Windows Subsystem For
Linux provides a Linux environment on Windows 10 which is capable of using the
Debian, Fedora, or source installation methods. More information about WSL can
be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
for Windows Server.
### Troubleshooting Installation
XXX a bunch of this is no longer relevant.
Synapse requires pip 8 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with `Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)`.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun `virtualenv -p python3 synapse` to update the virtual env.
Installing may fail during installing virtualenv with `InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.`
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with `mock requires setuptools>=17.1. Aborting installation`.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted
## Prebuilt packages
As an alternative to installing from source, prebuilt packages are available
for a number of platforms.
### Docker images and Ansible playbooks
There is an offical synapse image available at
https://hub.docker.com/r/matrixdotorg/synapse which can be used with
the docker-compose file available at [contrib/docker](contrib/docker). Further information on
this including configuration options is available in the README on
hub.docker.com.
Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
Dockerfile to automate a synapse server in a single Docker image, at
https://hub.docker.com/r/avhost/docker-matrix/tags/
Slavi Pantaleev has created an Ansible playbook,
which installs the offical Docker image of Matrix Synapse
along with many other Matrix-related services (Postgres database, riot-web, coturn, mxisd, SSL support, etc.).
For more details, see
https://github.com/spantaleev/matrix-docker-ansible-deploy
### Debian/Ubuntu
#### Matrix.org packages
Matrix.org provides Debian/Ubuntu packages of the latest stable version of
Synapse via https://matrix.org/packages/debian/. To use them:
```
sudo apt install -y lsb-release curl apt-transport-https
echo "deb https://matrix.org/packages/debian `lsb_release -cs` main" |
sudo tee /etc/apt/sources.list.d/matrix-org.list
curl "https://matrix.org/packages/debian/repo-key.asc" |
sudo apt-key add -
sudo apt update
sudo apt install matrix-synapse-py3
```
#### Downstream Debian/Ubuntu packages
For `buster` and `sid`, Synapse is available in the Debian repositories and
it should be possible to install it with simply:
```
sudo apt install matrix-synapse
```
There is also a version of `matrix-synapse` in `stretch-backports`. Please see
the [Debian documentation on
backports](https://backports.debian.org/Instructions/) for information on how
to use them.
We do not recommend using the packages in downstream Ubuntu at this time, as
they are old and suffer from known security vulnerabilities.
### Fedora
Synapse is in the Fedora repositories as `matrix-synapse`:
```
sudo dnf install matrix-synapse
```
Oleg Girko provides Fedora RPMs at
https://obs.infoserver.lv/project/monitor/matrix-synapse
### OpenSUSE
Synapse is in the OpenSUSE repositories as `matrix-synapse`:
```
sudo zypper install matrix-synapse
```
### SUSE Linux Enterprise Server
Unofficial package are built for SLES 15 in the openSUSE:Backports:SLE-15 repository at
https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/
### ArchLinux
The quickest way to get up and running with ArchLinux is probably with the community package
https://www.archlinux.org/packages/community/any/matrix-synapse/, which should pull in most of
the necessary dependencies.
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 ):
```
sudo pip install --upgrade pip
```
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv):
```
sudo pip uninstall py-bcrypt
sudo pip install py-bcrypt
```
### FreeBSD
Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
- Ports: `cd /usr/ports/net-im/py-matrix-synapse && make install clean`
- Packages: `pkg install py27-matrix-synapse`
### NixOS
Robin Lambertz has packaged Synapse for NixOS at:
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix
# Setting up Synapse
Once you have installed synapse as above, you will need to configure it.
## TLS certificates
The default configuration exposes two HTTP ports: 8008 and 8448. Port 8008 is
configured without TLS; it should be behind a reverse proxy for TLS/SSL
termination on port 443 which in turn should be used for clients. Port 8448
is configured to use TLS for Federation with a self-signed or verified
certificate, but please be aware that a valid certificate will be required in
Synapse v1.0.
If you would like to use your own certificates, you can do so by changing
`tls_certificate_path` and `tls_private_key_path` in `homeserver.yaml`;
alternatively, you can use a reverse-proxy. Apart from port 8448 using TLS,
both ports are the same in the default configuration.
### ACME setup
Synapse v1.0 will require valid TLS certificates for communication between servers
(port `8448` by default) in addition to those that are client-facing (port
`443`). In the case that your `server_name` config variable is the same as
the hostname that the client connects to, then the same certificate can be
used between client and federation ports without issue. Synapse v0.99.0+
**will provision server-to-server certificates automatically for you for
free** through [Let's Encrypt](https://letsencrypt.org/) if you tell it to.
In order for Synapse to complete the ACME challenge to provision a
certificate, it needs access to port 80. Typically listening on port 80 is
only granted to applications running as root. There are thus two solutions to
this problem.
#### Using a reverse proxy
A reverse proxy such as Apache or nginx allows a single process (the web
server) to listen on port 80 and proxy traffic to the appropriate program
running on your server. It is the recommended method for setting up ACME as
it allows you to use your existing webserver while also allowing Synapse to
provision certificates as needed.
For nginx users, add the following line to your existing `server` block:
```
location /.well-known/acme-challenge {
proxy_pass http://localhost:8009/;
}
```
For Apache, add the following to your existing webserver config::
```
ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge
```
Make sure to restart/reload your webserver after making changes.
#### Authbind
`authbind` allows a program which does not run as root to bind to
low-numbered ports in a controlled way. The setup is simpler, but requires a
webserver not to already be running on port 80. **This includes every time
Synapse renews a certificate**, which may be cumbersome if you usually run a
web server on port 80. Nevertheless, if you're sure port 80 is not being used
for any other purpose then all that is necessary is the following:
Install `authbind`. For example, on Debian/Ubuntu:
```
sudo apt-get install authbind
```
Allow `authbind` to bind port 80:
```
sudo touch /etc/authbind/byport/80
sudo chmod 777 /etc/authbind/byport/80
```
When Synapse is started, use the following syntax::
```
authbind --deep <synapse start command>
```
Finally, once Synapse is able to listen on port 80 for ACME challenge
requests, it must be told to perform ACME provisioning by setting `enabled`
to true under the `acme` section in `homeserver.yaml`:
```
acme:
enabled: true
```
## Registering a user
You will need at least one user on your server in order to use a Matrix
client. Users can be registered either via a Matrix client, or via a
commandline script.
To get started, it is easiest to use the command line to register new
users. This can be done as follows:
```
$ source ~/synapse/env/bin/activate
$ synctl start # if not already running
$ register_new_matrix_user -c homeserver.yaml https://localhost:8448
New user localpart: erikj
Password:
Confirm password:
Make admin [no]:
Success!
```
This process uses a setting `registration_shared_secret` in
`homeserver.yaml`, which is shared between Synapse itself and the
`register_new_matrix_user` script. It doesn't matter what it is (a random
value is generated by `--generate-config`), but it should be kept secret, as
anyone with knowledge of it can register users on your server even if
`enable_registration` is `false`.
## Setting up a TURN server
For reliable VoIP calls to be routed via this homeserver, you MUST configure
a TURN server. See [docs/turn-howto.rst](docs/turn-howto.rst) for details.
## URL previews
Synapse includes support for previewing URLs, which is disabled by default. To
turn it on you must enable the `url_preview_enabled: True` config parameter
and explicitly specify the IP ranges that Synapse is not allowed to spider for
previewing in the `url_preview_ip_range_blacklist` configuration parameter.
This is critical from a security perspective to stop arbitrary Matrix users
spidering 'internal' URLs on your network. At the very least we recommend that
your loopback and RFC1918 IP addresses are blacklisted.
This also requires the optional lxml and netaddr python dependencies to be
installed. This in turn requires the libxml2 library to be available - on
Debian/Ubuntu this means `apt-get install libxml2-dev`, or equivalent for
your OS.

Synapse Installation
====================
Synapse is the reference Python/Twisted Matrix homeserver implementation.
For details on how to install synapse, see `<INSTALL.md>`_.
System requirements:
- POSIX-compliant system (tested on Linux & OS X)
- Python 3.5, 3.6, 3.7, or 2.7
- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
Installing from source
----------------------
(Prebuilt packages are available for some platforms - see `Platform-Specific
Instructions`_.)
Synapse is written in Python but some of the libraries it uses are written in
C. So before we can install Synapse itself we need a working C compiler and the
header files for Python C extensions.
Installing prerequisites on Ubuntu or Debian::
sudo apt-get install build-essential python3-dev libffi-dev \

To install the Synapse homeserver run::
mkdir -p ~/synapse
virtualenv -p python3 ~/synapse/env
source ~/synapse/env/bin/activate
pip install --upgrade pip
pip install --upgrade setuptools
pip install matrix-synapse[all]
This installs Synapse, along with the libraries it uses, into a virtual
environment under ``~/synapse/env``. Feel free to pick a different directory
if you prefer.
This Synapse installation can then be later upgraded by using pip again with the
update flag::
source ~/synapse/env/bin/activate
pip install -U matrix-synapse[all]
In case of problems, please see the _`Troubleshooting` section below.
There is an offical synapse image available at
https://hub.docker.com/r/matrixdotorg/synapse/tags/ which can be used with
the docker-compose file available at `contrib/docker <contrib/docker>`_. Further information on
this including configuration options is available in the README on

Configuring Synapse
-------------------
Before you can start Synapse, you will need to generate a configuration
file. To do this, run (in your virtualenv, as before)::
cd ~/synapse
python -m synapse.app.homeserver \
--server-name my.domain.name \
--config-path homeserver.yaml \
--generate-config \
--report-stats=[yes|no]
... substituting an appropriate value for ``--server-name``. The server name
determines the "domain" part of user-ids for users on your server: these will
all be of the format ``@user:my.domain.name``. It also determines how other
matrix servers will reach yours for `Federation`_. For a test configuration,
set this to the hostname of your server. For a more production-ready setup, you
will probably want to specify your domain (``example.com``) rather than a
matrix-specific hostname here (in the same way that your email address is
probably ``user@example.com`` rather than ``user@email.example.com``) - but
doing so may require more advanced setup - see `Setting up
Federation`_. Beware that the server name cannot be changed later.
This command will generate you a config file that you can then customise, but it will
also generate a set of keys for you. These keys will allow your Home Server to
identify itself to other Home Servers, so don't lose or delete them. It would be
wise to back them up somewhere safe. (If, for whatever reason, you do need to
change your Home Server's keys, you may find that other Home Servers have the
old key cached. If you update the signing key, you should change the name of the
key in the ``<server name>.signing.key`` file (the second word) to something
different. See `the spec`__ for more information on key management.)

The default configuration exposes two HTTP ports: 8008 and 8448. Port 8008 is
configured without TLS; it should be behind a reverse proxy for TLS/SSL
termination on port 443 which in turn should be used for clients. Port 8448

both ports are the same in the default configuration.
ACME setup

For details on having Synapse manage your federation TLS certificates
automatically, please see `<docs/ACME.md>`_.
Registering a user
------------------
You will need at least one user on your server in order to use a Matrix
client. Users can be registered either `via a Matrix client`__, or via a
commandline script.

$ synctl start # if not already running
$ register_new_matrix_user -c homeserver.yaml https://localhost:8448
New user localpart: erikj
Password:
Confirm password:
Make admin [no]:
Success!
This process uses a setting ``registration_shared_secret`` in
``homeserver.yaml``, which is shared between Synapse itself and the
``register_new_matrix_user`` script. It doesn't matter what it is (a random
value is generated by ``--generate-config``), but it should be kept secret, as
anyone with knowledge of it can register users on your server even if
``enable_registration`` is ``false``.

https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/
ArchLinux
---------
The quickest way to get up and running with ArchLinux is probably with the community package
https://www.archlinux.org/packages/community/any/matrix-synapse/, which should pull in most of
the necessary dependencies.
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 )::
sudo pip install --upgrade pip
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv)::
sudo pip uninstall py-bcrypt
sudo pip install py-bcrypt
FreeBSD
-------
Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
- Ports: ``cd /usr/ports/net-im/py-matrix-synapse && make install clean``
- Packages: ``pkg install py27-matrix-synapse``
OpenBSD
-------
There is currently no port for OpenBSD. Additionally, OpenBSD's security
settings require a slightly more difficult installation process.
1) Create a new directory in ``/usr/local`` called ``_synapse``. Also, create a
new user called ``_synapse`` and set that directory as the new user's home.
This is required because, by default, OpenBSD only allows binaries which need
write and execute permissions on the same memory space to be run from
``/usr/local``.
2) ``su`` to the new ``_synapse`` user and change to their home directory.
3) Create a new virtualenv: ``virtualenv -p python2.7 ~/.synapse``
4) Source the virtualenv configuration located at
``/usr/local/_synapse/.synapse/bin/activate``. This is done in ``ksh`` by
using the ``.`` command, rather than ``bash``'s ``source``.
5) Optionally, use ``pip`` to install ``lxml``, which Synapse needs to parse
webpages for their titles.
6) Use ``pip`` to install this repository: ``pip install matrix-synapse``
7) Optionally, change ``_synapse``'s shell to ``/bin/false`` to reduce the
chance of a compromised Synapse server being used to take over your box.
After this, you may proceed with the rest of the install directions.
NixOS
-----
Robin Lambertz has packaged Synapse for NixOS at:
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix
Windows Install
---------------
If you wish to run or develop Synapse on Windows, the Windows Subsystem For
Linux provides a Linux environment on Windows 10 which is capable of using the
Debian, Fedora, or source installation methods. More information about WSL can
be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
for Windows Server.
Troubleshooting
===============
Troubleshooting Installation
----------------------------
Synapse requires pip 8 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with ``Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)``.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun ``virtualenv -p python3 synapse`` to update the virtual env.
Installing may fail during installing virtualenv with ``InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.``
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with ``mock requires setuptools>=17.1. Aborting installation``.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted

URL Previews
============
Synapse 0.15.0 introduces a new API for previewing URLs at
``/_matrix/media/r0/preview_url``. This is disabled by default. To turn it on
you must enable the ``url_preview_enabled: True`` config parameter and
explicitly specify the IP ranges that Synapse is not allowed to spider for
previewing in the ``url_preview_ip_range_blacklist`` configuration parameter.
This is critical from a security perspective to stop arbitrary Matrix users
spidering 'internal' URLs on your network. At the very least we recommend that
your loopback and RFC1918 IP addresses are blacklisted.
This also requires the optional lxml and netaddr python dependencies to be
installed. This in turn requires the libxml2 library to be available - on
Debian/Ubuntu this means ``apt-get install libxml2-dev``, or equivalent for
your OS.

# Synapse Docker
This Docker image will run Synapse as a single process. It does not provide a database

This Docker image will run Synapse as a single process. By default it uses a
sqlite database; for production use you should connect it to a separate
postgres database.
The image also does *not* provide a TURN server.
## Run
We do not currently offer a `latest` image, as this has somewhat undefined semantics.
We instead release only tagged versions so upgrading between releases is entirely
within your control.
### Using docker-compose (easier)
This image is designed to run either with an automatically generated configuration
file or with a custom configuration that requires manual editing.
This image is designed to run either with an automatically generated

directory in the data volume and write the application service Yaml

## TLS certificates
Synapse requires a valid TLS certificate. You can do one of the following:
* Provide your own certificate and key (as
`${DATA_PATH}/${SYNAPSE_SERVER_NAME}.crt` and
`${DATA_PATH}/${SYNAPSE_SERVER_NAME}.key`, or elsewhere by providing an
entire config as `${SYNAPSE_CONFIG_PATH}`).
* Use a reverse proxy to terminate incoming TLS, and forward the plain http
traffic to port 8008 in the container. In this case you should set `-e
SYNAPSE_NO_TLS=1`.
* Use the ACME (Let's Encrypt) support built into Synapse. This requires
`${SYNAPSE_SERVER_NAME}` port 80 to be forwarded to port 8009 in the
container, for example with `-p 80:8009`. To enable it in the docker
container, set `-e SYNAPSE_ACME=1`.
If you don't do any of these, Synapse will fail to start with an error similar to:
