🦁 Swarmproxy is a simple http proxy to limit your outbound traffic.
## ❓ FAQ
### What ist Swarmproxy?
Swarmproxy is a simply way to integrate a http proxy in your Docker swarm cluster or any other container network.
It acts as an centralized proxy to limit your outbound / egress traffic. You can also enable a whitelist filter to
limit the allowed domains. There is also an option to use a upstream proxy.
### What does Swarmproxy for you?
Enterprise and production environments often face more stringent security requirements.
Therefore, unfiltered Internet access may be prohibited.
So Swarmproxy could help you with these features:
- Prevent direct web access from Container workload.
- Upstream proxy with or without authentication
- Optional domain based whitelist filter.
### What does Swarmproxy not?
Swarmproxy is just a supercharged Tinyproxy where you can point your container workload to.
> ☣️ Swarmproxy does not block the web access or other traffic if the proxy is not used. It's not a firewall, and it
> does not customize your iptables or so

- `1`, `0.1`, `0.1.0` - tag based version.
> **💡 NOTE: See the [packages page](https://gitea.ocram85.com/OCram85/-/packages/container/swarmproxy/latest) for latest version and all other available tags.**
### 2. 🛡️ Run as Docker Swarm Stack
```yaml
version: "3.8"
networks:
egress:
attachable: true
#external: true
#configs:
# filter_file:
# # config can be predefined / external or loaded from file
# #external: true
# file: ./filter.txt
#secrets:
# upstream-proxy:
# external: true
services:
swarmproxy:
# Do not use the `latest` tag in production!
image: gitea.ocram85.com/OCram85/swarmproxy:latest
deploy:
replicas: 1
#secrets:
# - upstream-proxy
environment:
# Recommended settings
# Use an optional upstream proxy
#- UPSTREAM_PROXY=
# Set UPSTREAM_PROXY as docker secret if your upstream needs authentication
# Eg.: http://user:password@upstream.intra:3128
#- UPSTREAM_PROXY_FILE=/run/secrets/UPSTREAM_PROXY
# OPTIONAL config keys
#- TINYPROXY_UID=5123
#- TINYPROXY_GID=5123
#- PORT=8888
#- TIMEOUT=600
#- LOGLEVEL=Info
#- MAXCLIENTS=600
#- FILTER_FILE=/app/filter
volumes:
# You can mount a single filter file into the container.
# To reload the file use the docker kill -s USR1 command.
- ./filter.txt:/app/filter:ro
configs:
- source: filter_file
target: /app/filter
networks:
egress:
aliases:
- swarmproxy
- proxy
```
### 3. Use the proxy form other containers
## 💣 Known Issues
## 😡 We're Using GitHub Under Protest
This project is currently **mirrored** to GitHub. This is not ideal; GitHub is a
proprietary, trade-secret system that is not Free and Open Source Software
(FOSS). We are deeply concerned about using a proprietary system like GitHub
to develop our FOSS project. We have an
[open Gitea repository ](https://gitea.ocram85.com/OCram85/swarmproxy/issues) where the
project contributors are actively discussing how we can move away from GitHub
in the long term. We urge you to read about the
[Give up GitHub](https://GiveUpGitHub.org) campaign from
[the Software Freedom Conservancy](https://sfconservancy.org) to understand
some of the reasons why GitHub is not a good place to host FOSS projects.
If you are a contributor who personally has already quit using GitHub, please
[check this resource](https://gitea.ocram85.com/OCram85/swarmproxy) for how to send us contributions without
using GitHub directly.
Any use of this project's code by GitHub Copilot, past or present, is done
without our permission. We do not consent to GitHub's use of this project's
code in Copilot.
