The outpost upstream was being passed directly to Caddy's dial field with the
full URL (http://host:port), but Caddy expects just host:port. This was causing
DNS lookup errors with a leading slash (/authentik.bologna.local.fuo.fi).
Now properly parses the URL to extract just the hostname and port.
The outpost route now preserves the original request host (e.g., email.fuo.fi)
instead of changing it to the upstream host. This allows Authentik to properly
construct redirect URLs after processing authentication callbacks.
- Implemented health monitoring service that detects Caddy restarts/crashes
- Automatically reapplies configuration when Caddy restarts
- Added metrics settings UI for enabling Prometheus/Grafana monitoring
- Caddy metrics exposed on separate port (default: 9090) via reverse proxy
- Admin API (port 2019) kept internal-only for security
- Updated docker-compose.yml with metrics port documentation

The forward_auth directive only exists in Caddyfile syntax, not JSON config.
This fix converts Authentik authentication to use the underlying reverse_proxy
handler with proper configuration:
- Replace forward_auth handler with reverse_proxy
- Convert "private_ranges" keyword to actual CIDR blocks for JSON config
- Parse upstream URL to extract host:port for dial field (removing http://)
- Add handle_response block to copy Authentik headers on 2xx status
- Preserve X-Forwarded-Method and X-Forwarded-Uri headers
Fixes error: "unknown module: http.handlers.forward_auth"
Fixes error: "invalid IP address: 'private_ranges'"
Fixes error: "lookup /hostname: no such host" (dial with URL scheme)

Previously, proxy hosts with "Managed by Caddy (Auto)" (certificate_id = null)
were being skipped during Caddy configuration generation, causing the feature
to not work at all.
This commit adds full support for automatic certificate management:
1. Modified collectCertificateUsage() to track domains with null certificate_id
separately as auto-managed domains
2. Updated buildTlsAutomation() to create ACME automation policies for
auto-managed domains (supports both HTTP-01 and DNS-01 challenges)
3. Modified buildTlsConnectionPolicies() to include TLS connection policies
for auto-managed domains
4. Updated buildProxyRoutes() to allow proxy hosts with null certificate_id
to be included in the route configuration
The configuration now automatically updates when domains are changed, as
applyCaddyConfig() is already called on create/update/delete operations.
Caddy will now automatically obtain and manage Let's Encrypt certificates
for all domains when "Managed by Caddy (Auto)" is selected.
Previously, upstream URLs like 'https://iot2.fuo.fi' were passed directly
to Caddy's dial field, causing DNS lookup errors like 'lookup /iot2.fuo.fi'.
Changes:
- Parse upstream URLs to extract hostname:port for Caddy's dial field
- Automatically detect HTTPS upstreams and configure TLS transport
- Support insecure_skip_verify flag for self-signed certificates
- Default to port 443 for https://, port 80 for http://
Fixes: 'dial tcp: lookup /host: no such host' errors when using URL
format for upstreams instead of host:port format.
Previously, managed certificates required Cloudflare DNS to be configured,
otherwise no TLS automation was configured and HTTPS would fail with TLS
handshake errors.
Changes:
- When Cloudflare is configured: use DNS-01 challenge via Cloudflare
- When Cloudflare is NOT configured: use HTTP-01 challenge (default)
- Enable automatic HTTPS when TLS automation policies exist
- This allows Let's Encrypt certificates via HTTP-01 challenge
Fixes TLS handshake errors when using managed certificates without
Cloudflare configuration. Port 80 must be accessible for HTTP-01.
When POSTing config to /load, Caddy was resetting the admin endpoint
from 0.0.0.0:2019 to localhost:2019, making it inaccessible from the
web container.
Now explicitly include admin config in the generated JSON to ensure
the admin API remains accessible at 0.0.0.0:2019 after config reloads.
Fixes ECONNREFUSED errors when applying Caddy config after the first load.
The caddy-dns/cloudflare module only accepts api_token.
Both zone_id and account_id fields are not supported and cause config errors.
The provider automatically handles all zones accessible by the API token.
Fixes: 'unknown field zone_id' error when applying Caddy config.
The caddy-dns/cloudflare module only supports api_token and zone_id fields.
The account_id field was causing config load errors: 'unknown field account_id'.
Fixes Caddy config validation error when using Cloudflare DNS for ACME challenges.
