# tailscale-sidecar

Installs the [Tailscale](https://tailscale.com/) client and runs it as a sidecar container in docker compose environments.

## Usage

Let's say you want your tailscale network to be accessible from your prometheus container.

Add the sidecar section to your `docker-compose.yaml`:

```yaml

version: "3"

networks:

  monitoring-network:

    external: true

  nginx-network:

    external: true

services:

  sidecar:

    image: ghcr.io/night-crawler/tailscale-sidecar:main

    cap_add:

      - NET_ADMIN

    sysctls:

     - net.ipv4.conf.all.src_valid_mark=1

    network_mode: 'service:prometheus'

    environment:

      TS_AUTHKEY: 

      TS_HOSTNAME: prometheus-sidecar

      TS_LOGIN_SERVER: http://headscale.nginx-network:8080

    devices:

      - /dev/net/tun

  prometheus:

    build: ./prometheus

    restart: unless-stopped

    networks:

      - monitoring-network

      - nginx-network

    volumes:

      - ./data/prometheus:/prometheus

```

Exec into the prometheus container and ping some internal host:

```bash

docker compose exec prometheus bash

ping 100.64.0.3

```
