# Getting Started with Docker and Traefik
|
|
|
|
Docker is a first-class citizen in Traefik, offering native support for Docker containers and services.
|
|
Whether you're using Docker Compose or running containers directly, Traefik provides a seamless experience for managing your Docker traffic.
|
|
|
|
This guide shows you how to:
|
|
|
|
- Install Traefik using Docker
|
|
- Expose the Traefik dashboard
|
|
- Deploy a sample application
|
|
- Configure basic routing
|
|
|
|
## Prerequisites
|
|
|
|
- Docker
|
|
- Docker Compose (optional)
|
|
|
|
## Install Traefik
|
|
|
|
### Using Docker Compose
|
|
|
|
Create a Docker Compose file.
|
|
This configuration:
|
|
|
|
- Exposes ports 80 and 8080.
|
|
- Enables the Docker provider
|
|
- Configures the dashboard with basic settings. Port 8080 serves the dashboard because we enabled `--api.insecure=true` (development use only)
|
|
- Mounts the Docker socket for container discovery
|
|
|
|
```yaml
|
|
# docker-compose.yml
|
|
services:
|
|
traefik:
|
|
image: traefik:v3.5
|
|
command:
|
|
- "--api.insecure=true"
|
|
- "--providers.docker=true"
|
|
- "--entrypoints.web.address=:80"
|
|
ports:
|
|
- "80:80"
|
|
- "8080:8080"
|
|
volumes:
|
|
- /var/run/docker.sock:/var/run/docker.sock
|
|
```
|
|
|
|
Start Traefik:
|
|
|
|
```bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
### Using Docker CLI
|
|
|
|
Alternatively, you can run Traefik directly with Docker.
|
|
This command:
|
|
|
|
- Exposes ports 80 and 8080 for web traffic and dashboard access
|
|
- Mounts the configuration file and Docker socket
|
|
- Uses the same configuration as the Docker Compose example
|
|
|
|
Create a configuration file:
|
|
|
|
```yaml
|
|
# traefik.yml
|
|
api:
|
|
insecure: true
|
|
entryPoints:
|
|
web:
|
|
address: ":80"
|
|
providers:
|
|
docker: {}
|
|
```
|
|
|
|
Start Traefik:
|
|
|
|
```bash
|
|
docker run -d \
|
|
-p 80:80 \
|
|
-p 8080:8080 \
|
|
-v $PWD/traefik.yml:/etc/traefik/traefik.yml \
|
|
-v /var/run/docker.sock:/var/run/docker.sock \
|
|
traefik:v3.5
|
|
```
|
|
|
|
## Expose the Dashboard
|
|
|
|
Because we explicitly enabled insecure mode, the [dashboard](../reference/install-configuration/api-dashboard.md) is reachable on port 8080 without authentication.
|
|
**Do not enable this flag in production**.
|
|
|
|
You can access the dashboard at:
|
|
|
|
[http://localhost:8080/dashboard/](http://localhost:8080/dashboard/)
|
|
|
|
|
|
|
|
## Deploy a Sample Application
|
|
|
|
Create a whoami service:
|
|
|
|
```yaml
|
|
# whoami.yml
|
|
services:
|
|
whoami:
|
|
image: traefik/whoami
|
|
labels:
|
|
- "traefik.http.routers.whoami.rule=Host(`whoami.localhost`)"
|
|
```
|
|
|
|
Apply the configuration:
|
|
|
|
```bash
|
|
docker-compose -f whoami.yml up -d
|
|
```
|
|
|
|
## Test Your Setup
|
|
|
|
You can use the following curl command to verify that the application is correctly exposed:
|
|
|
|
```bash
|
|
curl http://whoami.localhost
|
|
|
|
Hostname: 068c0a29a8b7
|
|
IP: 127.0.0.1
|
|
IP: ::1
|
|
IP: 192.168.147.3
|
|
RemoteAddr: 192.168.147.2:56006
|
|
GET / HTTP/1.1
|
|
Host: whoami.localhost
|
|
User-Agent: curl/8.7.1
|
|
Accept: */*
|
|
Accept-Encoding: gzip
|
|
X-Forwarded-For: 192.168.147.1
|
|
X-Forwarded-Host: whoami.localhost
|
|
X-Forwarded-Port: 80
|
|
X-Forwarded-Proto: http
|
|
X-Forwarded-Server: 9232cdd4fd6c
|
|
X-Real-Ip: 192.168.147.1
|
|
```
|
|
|
|
You can also open [http://whoami.localhost](http://whoami.localhost) in a browser to test the application:
|
|
|
|
|
|
|
|
If you navigate to the **HTTP Routers** section of the Traefik dashboard, you can see that the `whoami.localhost` route is managed by the Traefik Docker provider:
|
|
|
|
|
|
|
|
That's it! You've successfully deployed Traefik and configured routing in Docker.
