# Stunnel Container Image | ||
|
||
![Redistributable](https://img.shields.io/badge/Redistributable-Yes-green) | ||
|
||
|
||
## Description | ||
|
||
Stunnel is an open-source multi-platform application used to provide a universal | ||
TLS/SSL tunneling service. | ||
|
||
|
||
## How to use this Image | ||
|
||
The Stunnel Container Image launches `stunnel` in its entrypoint using the | ||
default configuration shipped with the package. The container must be provided | ||
with a server certificate to establish TLS/SSL connections. It expects the | ||
server key in `/etc/stunnel/stunnel.key` and the certificate in | ||
`/etc/stunnel/stunnel.pem` or in the locations set in the environment variables | ||
`STUNNEL_KEY` and `STUNNEL_CERT`. | ||
|
||
The entrypoint can setup a single service via environment variables so that the | ||
user doesn't have to write and mount their own configuration file. This can be | ||
setup via the environment variables `STUNNEL_SERVICE_NAME`, `STUNNEL_ACCEPT` and | ||
`STUNNEL_CONNECT`: | ||
|
||
- `STUNNEL_SERVICE_NAME`: name or otherwise unique identifier of the service | ||
(used for documentation purpose only) | ||
|
||
- `STUNNEL_ACCEPT`: address on which new connections should be accepted, can be | ||
either a hostname + port number or just a port number (then localhost is | ||
assumed as the host) | ||
|
||
- `STUNNEL_CONNECT`: address on which the un-encrypted service is listening and | ||
to which stunnel connects, can be either a hostname + port number or just a | ||
port number (then localhost is assumed as the host) | ||
|
||
|
||
For example to create an SSL endpoint for a webserver listening on port `8000` | ||
on localhost, execute: | ||
|
||
```bash | ||
podman run --rm -d \ | ||
-p 443:443 \ | ||
-e STUNNEL_SERVICE_NAME=webserver \ | ||
-e STUNNEL_ACCEPT=443 \ | ||
-e STUNNEL_CONNECT=8000 \ | ||
-v=path/to/server.pem:/etc/stunnel/stunnel.pem:Z \ | ||
-v=path/to/server.crt:/etc/stunnel/stunnel.crt:Z \ | ||
registry.opensuse.org/opensuse/stunnel:5 | ||
``` | ||
|
||
