Automatic HTTPS and local domain routing for Docker Compose services using Traefik and Step-CA.
</p>
</div>
Created by [@Sajito](https://github.com/Sajito)
## Setup
1. Clone this repository and navigate into the directory.
2. Start the services:
```bash
docker compose up -d
```
3. Trust the Step-CA root certificate:
```bash
curl -k https://localhost:9000/roots.pem -o roots.pem
sudo trust anchor --store roots.pem
rm roots.pem
```
## How to Use
1. Add a label to your docker compose service:
```yaml
labels:
serviceName: my-app
```
2. Your service will be accessible at `https://my-app.dev.local`.
## Troubleshooting
- If routes do not work you can open the traefik dashboard under [https://traefik.vm](https://traefik.vm) and check if the service and route exist.
- If your service is not reachable it could mean that traefik did not detect the correct port. You can set the port manually in your docker compose file:
```yaml
labels:
traefik.http.services.my-app.loadbalancer.server.port: 8080
```
> [!IMPORTANT]
> For each overwritten port you need to specify a custom `service-label` `traefik.http.services.[service-label]`. Otherwise the custom port will not be detected.
- If certificates are not renewed or have expired
```bash
docker compose up -d --force-recreate traefik
```
## Tipps
### Custom Domain Suffix
For example `dev.cool` 😎
Replace `.dev.local` with your custom domain suffix in the `config/traefik/traefik.yml` file:
```yaml
...
docker:
defaultRule: |
Host(`{{ trim (index .Labels "serviceName") }}.dev.cool`) {{range $i, $domain := splitList "," (index .Labels "serviceDomains")}}{{if ne $domain ""}}|| Host(`{{$domain}}`){{end}}{{end}}
...
```
Replace `.dev.local` with your custom domain suffix in the `config/dns/config.sample.json` file:
```json
...
{
"id": 2,
"hostname": ".dev.cool",
"ip": "",
"target": "host.docker",
"ttl": 3600,
"type": "CNAME"
}
...
```
Remove the dns_config volume
```bash
docker compose down
docker compose volukme rm dns_config
docker compose up -d
```
### Certificate Lifetime
To ensure Traefik has enough time to renew certificates, increase their duration:
```bash
docker compose exec step step ca provisioner update acme \
--x509-min-dur=20m \
--x509-max-dur=8760h \
--x509-default-dur=2160h
```
### Use the preconfigured services
If you use the preconfigured services, you can add the following snippet to you `.bashrc/.zshrc` to easily start, stop, and manage the services.
```bash
dev () {
PROJECT_DIR="$HOME/Projects/dev/services"
case "$1" in
(start) shift
docker compose -f "$PROJECT_DIR/docker-compose.yml" --profile "$@" up -d ;;
(restart) shift
docker compose -f "$PROJECT_DIR/docker-compose.yml" --profile "$@" restart ;;
(stop) shift
docker compose -f "$PROJECT_DIR/docker-compose.yml" --profile "$@" down --remove-orphans ;;
(logs) shift
docker compose -f "$PROJECT_DIR/docker-compose.yml" --profile "$@" logs -f ;;
(*) echo "Usage: dev {start|restart|stop|logs} [services...]" ;;
esac
}
```
