Pull request overview

This PR introduces a new notifications stack (ntfy + Gotify) and wires Alertmanager to send alerts to ntfy, alongside adding a new “enhanced” Authentik setup script and a unified notification sender script.

Changes:

Add stacks/notifications (compose + README) to deploy ntfy and Gotify behind Traefik.
Add ntfy server configuration and update Alertmanager routing to use an ntfy webhook receiver.
Add helper scripts: scripts/notify.sh (notification sender) and setup-authentik-enhanced.sh (Authentik/OIDC automation).

scripts/notify.sh

+main() {
+    # Check for help
+    if [[ "$1" == "-h" ]] || [[ "$1" == "--help" ]]; then
+        show_help
+        exit 0
+    fi
+
+    # Validate arguments
+    if [[ $# -lt 3 ]]; then
+        error "Missing required arguments"


main() references $1 before checking #$ with set -u enabled, so running the script with no arguments will error with an unbound variable instead of showing help. Guard the help check with if [[ $# -gt 0 ]] (or similar) before reading $1.

scripts/notify.sh

+    # Sanitize topic (only allow alphanumeric, dash, underscore)
+    local sanitized_topic=$(echo "$topic" | tr -cd '[:alnum:]-_')
+
+    if [[ "$sanitized_topic" != "$topic" ]]; then
+        log "Sanitized topic from '$topic' to '$sanitized_topic'"
+        topic="$sanitized_topic"
+    fi


The topic “sanitization” uses tr -cd '[:alnum:]-_', where - is treated as a range operator in tr and may allow unintended characters through. Put - at the end (or escape it), e.g. tr -cd '[:alnum:]_-', to ensure only alnum/underscore/dash are allowed.

scripts/notify.sh

+    local json_payload="{
+        \"topic\": \"${topic}\",
+        \"title\": \"${title}\",
+        \"message\": \"${message}\",
+        \"priority\": ${priority}"

+        json_payload+=", \"tags\": ${tags_json}"
+    fi
+
+    json_payload+="}"
+


The JSON payload is constructed via string interpolation without JSON escaping for title/message/topic/tags. If any value contains quotes, backslashes, or newlines, the payload becomes invalid (and can be abused to inject extra JSON fields). Build the payload with jq -n --arg ... (or similar) to ensure correct escaping.

Suggested change

local json_payload="{

\"topic\": \"${topic}\",

\"title\": \"${title}\",

\"message\": \"${message}\",

\"priority\": ${priority}"

if [[ -n "$tags" ]]; then

# Convert comma-separated tags to array

IFS=',' read -ra TAG_ARRAY <<< "$tags"

local tags_json="["

for tag in "${TAG_ARRAY[@]}"; do

tags_json+="\"${tag}\","

done

tags_json="${tags_json%,}]"

json_payload+=", \"tags\": ${tags_json}"

scripts/notify.sh

+    if curl -s -X POST \
+        -H "Content-Type: application/json" \
+        -H "Authorization: Bearer ${NTFY_TOKEN:-}" \
+        -d "${json_payload}" \
+        "${NTFY_BASE_URL}"; then
+        log "ntfy notification sent successfully"


send_ntfy always sets Authorization: Bearer ${NTFY_TOKEN:-} even when NTFY_TOKEN is unset/empty, which can cause auth failures on servers that treat an empty bearer token as invalid. Only add the Authorization header when NTFY_TOKEN is non-empty, and document NTFY_TOKEN in the script help if it’s supported.

scripts/notify.sh

+# Make script executable and run
+if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
+    # Ensure script is executable
+    if [[ ! -x "$0" ]]; then
+        chmod +x "$0"
+    fi


The script attempts to chmod +x "$0" at runtime. This is surprising behavior, can fail in read-only contexts, and is unnecessary if the repo sets the executable bit. Prefer setting the file mode in git (or documenting chmod +x scripts/notify.sh) and remove self-modifying behavior.

Suggested change

# Make script executable and run

if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then

# Ensure script is executable

if [[ ! -x "$0" ]]; then

chmod +x "$0"

fi

# Run when executed directly

stacks/notifications/README.md

+### 3. Access the services
+
+- **ntfy Web UI**: https://ntfy.your-domain.com
+- **Gotify Web UI**: http://your-server:8080
+


Access instructions for Gotify point to http://your-server:8080, but the compose file doesn’t publish port 8080 and instead configures Traefik routing on gotify.${DOMAIN} over websecure. Update the README to match the actual access method (or publish the port if that’s intended).

config/alertmanager/alertmanager.yml

  group_wait: 30s
  group_interval: 5m
  repeat_interval: 12h
-  receiver: default
+  receiver: ntfy
  routes:
    - match:
        severity: critical
-      receiver: default
+      receiver: ntfy


The top-level route receiver is changed to ntfy, but the configured webhook URL is a placeholder (https://ntfy.example.com/...). As-is, Alertmanager will send alerts to the wrong destination (or fail) in default deployments. Use a working default (e.g., keep receiver: default unless configured) and/or make the URL environment-expandable and update the monitoring compose to pass --config.expand-env and the needed env vars.

config/alertmanager/alertmanager.yml

+      # IMPORTANT: Replace 'example.com' with your actual domain in the URL below
+      # This URL will not auto-expand ${DOMAIN} unless Alertmanager is started with --config.expand-env
+      # and has DOMAIN in its environment. Update to your actual domain: https://ntfy.your-domain.com/homelab-alerts
+      - url: 'https://ntfy.example.com/homelab-alerts'


The ntfy webhook URL is hard-coded to https://ntfy.example.com/homelab-alerts with a note to manually replace it. This is easy to miss and will break alert delivery. Prefer wiring this through env expansion (and enabling --config.expand-env in Alertmanager) or using an internal reachable URL based on your networking, so the default config works out of the box.

Suggested change

# IMPORTANT: Replace 'example.com' with your actual domain in the URL below

# This URL will not auto-expand ${DOMAIN} unless Alertmanager is started with --config.expand-env

# and has DOMAIN in its environment. Update to your actual domain: https://ntfy.your-domain.com/homelab-alerts

- url: 'https://ntfy.example.com/homelab-alerts'

# Set NTFY_WEBHOOK_URL in Alertmanager's environment and start Alertmanager

# with --config.expand-env so this value is expanded at runtime.

# Example: https://ntfy.your-domain.com/homelab-alerts

- url: '${NTFY_WEBHOOK_URL}'

stacks/notifications/docker-compose.yml

    environment:
-      - TZ=${TZ:-Asia/Shanghai}
-    command: serve
-    labels:
-      - traefik.enable=true
-      - "traefik.http.routers.ntfy.rule=Host(`ntfy.${DOMAIN}`)"
-      - traefik.http.routers.ntfy.entrypoints=websecure
-      - traefik.http.routers.ntfy.tls=true
-      - traefik.http.services.ntfy.loadbalancer.server.port=80
+      - TZ=${TZ:-UTC}
+      - NTFY_BASE_URL=https://ntfy.${DOMAIN:-example.com}
+    networks:
+      - proxy


This stack defaults DOMAIN to example.com in Traefik host rules and NTFY_BASE_URL. In this repo other stacks treat DOMAIN as required; defaulting to example.com can lead to confusing misconfigurations and failed ACME attempts. Prefer requiring DOMAIN (no default) and failing fast when it’s unset.

+# Version: 1.0.0

PR description states a complete test suite is available via ./test-sso-integration.sh, but there is no such script in the repository with this change set. Either add the referenced test script (and any harness it needs) or update the PR description to match what’s actually included.
