# Adjusting SSL certificate retrieval (optional, advanced)
|
|
|
|
By default, this playbook retrieves and auto-renews free SSL certificates from [Let's Encrypt](https://letsencrypt.org/) for the domains it needs (e.g. `matrix.<your-domain>` and others)
|
|
|
|
This guide is about using the integrated Traefik server and doesn't apply if you're using [your own webserver](configuring-playbook-own-webserver.md).
|
|
|
|
|
|
## Using staging Let's Encrypt certificates instead of real ones
|
|
|
|
For testing purposes, you may wish to use staging certificates provide by Let's Encrypt.
|
|
|
|
You can do this with the following configuration:
|
|
|
|
```yaml
|
|
devture_traefik_config_certificatesResolvers_acme_use_staging: true
|
|
```
|
|
|
|
|
|
## Disabling SSL termination
|
|
|
|
For testing or other purposes, you may wish to install services without SSL termination and have services exposed to `http://` instead of `https://`.
|
|
|
|
You can do this with the following configuration:
|
|
|
|
```yaml
|
|
devture_traefik_config_entrypoint_web_secure_enabled: false
|
|
```
|
|
|
|
|
|
## Using self-signed SSL certificates
|
|
|
|
To use self-signed SSL certificates, you need to:
|
|
|
|
- disable `certResolvers` in Traefik, so it won't attempt to retrieve SSL certificates using the default certificate resolver (using [ACME](https://en.wikipedia.org/wiki/Automatic_Certificate_Management_Environment) / [Let's Encrypt](https://letsencrypt.org/))
|
|
- put a custom Traefik configuration file on the server, with the help of this Ansible playbook (via the `matrix-aux` role) or manually
|
|
- register your custom configuration file with Traefik, by adding an extra provider of type [file](https://doc.traefik.io/traefik/providers/file/)
|
|
- put the SSL files on the server, with the help of this Ansible playbook (via the `matrix-aux` role) or manually
|
|
|
|
```yaml
|
|
# Disable ACME / Let's Encrypt support
|
|
devture_traefik_config_certificatesResolvers_acme_enabled: false
|
|
|
|
# Unset the default certificate resolver
|
|
devture_traefik_certResolver_primary: ''
|
|
|
|
# Keep the SSL directory normally used for ACME / Let's Encrypt certificates.
|
|
# We need to explicitly enable this, because disabling ACME support (above) automatically disables it otherwise.
|
|
devture_traefik_ssl_dir_enabled: true
|
|
|
|
# Tell Traefik to load our custom configuration file (certificates.yml).
|
|
# The file is created below. See `matrix_aux_file_definitions`.
|
|
# The `/config/..` path is an in-container path, not a path on the host. Do not change it!

|
|
file:
|
|
filename: /config/certificates.yml

|
|
|
|
# Use the matrix-aux role to create our custom files on the server.
|
|
# If you'd like to do this manually, you remove this `matrix_aux_file_definitions` variable.
|
|
matrix_aux_file_definitions:
|
|
# Create the privkey.pem file on the server by
|
|
# uploading a file from the computer where Ansible is running.
|
|
- dest: "{{ devture_traefik_ssl_dir_path }}/privkey.pem"
|
|
src: /path/on/your/Ansible/computer/to/privkey.pem
|
|

|
# Create the cert.pem file on the server
|
|
# uploading a file from the computer where Ansible is running.
|

- dest: "{{ devture_traefik_ssl_dir_path }}/cert.pem"
|

src: /path/on/your/Ansible/computer/to/cert.pem

# The `/ssl/..` paths below are in-container paths, not paths on the host. Do not change them!
