Static YAML

Static YAML

Use this mode to configure EasyHAProxy from a hand-written YAML file. Works for any backend — Docker containers, VMs, bare-metal servers, or anything reachable by IP/hostname.

:::tip Live Reload EasyHAProxy monitors this file for changes and automatically reconfigures HAProxy when any changes are detected. :::

Step 1 — Write a minimal config file

containers:
  "myapp.example.com:80":
    ip: ["10.0.0.5:3000"]

Save this as config.yml.

Step 2 — Run EasyHAProxy

docker run -d \
      --name easy-haproxy-container \
      -v /my/static/:/etc/easyhaproxy/static/ \
      -e EASYHAPROXY_DISCOVER="static" \
      -p 80:80 \
      -p 443:443 \
      -p 1936:1936 \
    byjg/easy-haproxy

:::tip Docker Socket Optional Mounting /var/run/docker.sock is not required in static discovery mode. :::

Step 3 — Verify

curl http://myapp.example.com

  # Redirect www → main domain
  "www.host1.com.br:80":
    ip: ["container:5000"]
    redirect_ssl: true

:::note SSL Certificates in Static Mode The only way to provide SSL certificates in static configuration mode is to map the certificate files as a Docker volume. See the SSL documentation to learn how to configure this. :::
