## Fullstack example with external secrets and config `(3-external.yml)`
### Source
> 🗄️ File: [3-upstream.yml](3-upstream.yml)
### Description
This stack is based on the previous upstream example. It's modified to show these additional features:
- Using external docker secret to set up an upstream proxy. Should be used when upstream needs authentication
- Mounting a docker config as filter file
- filtering queries by domains
- added curl-blocked service to show output if target domain is not in whitelist
### Usage
```bash
echo "google.com" | docker config create filter_file -
echo "upstream:8888" | docker secret create upstream-proxy -
docker stack deploy -c 1-minimal.yml swarmproxy-mini
```
