Current Behavior

GetDERPMap fails to populate initial DERPMap causing initilization to fail

Expected Behavior

GetDERPMap succesfully gets DERPMap and populates initial DERPMap

Steps To Reproduce

  1. On Ubuntu
  2. With the following docker-compose (main difference is network for reverse proxy and volume to get cert and key from caddy reverse proxy
services:
  headscale:
    image: headscale/headscale:unstable
    restart: unless-stopped
    container_name: headscale
    ports:
      #- "0.0.0.0:8080:8080"
      - "127.0.0.1:9090:9090"
    volumes:
      # pls change [config_path] to the fullpath of the config folder just created
      - ./config:/etc/headscale
      - caddy_data:/etc
    command: serve
    networks:
      reverseproxy-nw:
  
  headscale-ui:
    container_name: headscale-ui
    image: ghcr.io/gurucomputing/headscale-ui:latest
    restart: unless-stopped
    networks:
      reverseproxy-nw:


networks:
  reverseproxy-nw:
    external: true

volumes:
  caddy_data:
    external: true
  1. run docker compose up -d
  2. run docker logs headscale
  3. see error

Environment

- OS:Ubuntu Server 24.04
- Headscale version: v0.23.0-alpha12
- Tailscale version: 1.68.1

Runtime environment

  • Headscale is behind a (reverse) proxy
  • Headscale runs in a container

Anything else?

Headscale config:

---
# headscale will look for a configuration file named `config.yaml` (or `config.json`) in the following order:
#
# - `/etc/headscale`
# - `~/.headscale`
# - current working directory

# The url clients will connect to.
# Typically this will be a domain like:
#
# https://myheadscale.example.com:443
#
server_url: https://hs.<domain>.dev

# Address to listen to / bind to on the server
#
# For production:
# listen_addr: 0.0.0.0:8080
listen_addr: 0.0.0.0:8080

# Address to listen to /metrics, you may want
# to keep this endpoint private to your internal
# network
#
metrics_listen_addr: 0.0.0.0:9090

# Address to listen for gRPC.
# gRPC is used for controlling a headscale server
# remotely with the CLI
# Note: Remote access _only_ works if you have
# valid certificates.
#
# For production:
# grpc_listen_addr: 0.0.0.0:50443
grpc_listen_addr: 127.0.0.1:50443

# Allow the gRPC admin interface to run in INSECURE
# mode. This is not recommended as the traffic will
# be unencrypted. Only enable if you know what you

### TLS configuration
#
## Let's encrypt / ACME
#
# headscale supports automatically requesting and setting up
# TLS for a domain with Let's Encrypt.
#
# URL to ACME directory
acme_url: https://acme-v02.api.letsencrypt.org/directory

# Email to register with ACME provider
acme_email: ""

# Domain name to request a TLS certificate for:
tls_letsencrypt_hostname: ""

# Path to store certificates and metadata needed by
# letsencrypt
# For production:
tls_letsencrypt_cache_dir: /etc/headscale/cache

# Type of ACME challenge to use, currently supported types:
# HTTP-01 or TLS-ALPN-01
# See [docs/tls.md](docs/tls.md) for more information
tls_letsencrypt_challenge_type: TLS-ALPN-01
# When HTTP-01 challenge is chosen, letsencrypt must set up a
# verification endpoint, and it will be listening on:
# :http = port 80
tls_letsencrypt_listen: ":http"

## Use already defined certificates:
tls_cert_path: "/etc/caddy/certificates/acme-v02.api.letsencrypt.org-directory/hs.<domain>.dev/hs.<domain>.dev.crt"
tls_key_path: "/etc/caddy/certificates/acme-v02.api.letsencrypt.org-directory/hs.<domain>dev/hs.<domain>.dev.key"

This sounds like your machine or container is missing CA root certs, try to mount them from the OS into the container.

We dont officially support containers, so I will close this one, if this solves your issue, please contribute to the docker docs.
