Notifications in slack doesn't include images

Grafana Alerting
,
1

Hello everyone!

I want slack notifications include images of panel

I’m using v8.3.0 Grafana version

I start it with prometheus and grafana-image-renderer in docker-compose
docker-compose.yml:

version: '2'

services:
  grafana:
    container_name: grafana
    image: grafana/grafana:main
    ports:
      - '3000:3000'
    environment:
      GF_RENDERING_SERVER_URL: "http://grafanarender:8081/render"
      GF_RENDERING_CALLBACK_URL: "http://grafana:3000/"
      GF_LOG_FILTERS: "rendering:debug"
      GF_INSTALL_PLUGINS: "grafana-clock-panel,grafana-simple-json-datasource,grafana-image-renderer"
    volumes:
      - /home/ivan2g/workspace/test_grafana_renderer/storage/:/var/lib/grafana
  renderer:
    container_name: grafanarender
    image: rebuild_grafanarender
    ports:
      - '8081:8081'
    volumes:
      - /home/ivan2g/workspace/test_grafana_renderer/config.json:/usr/src/app/config.json
  prometheus:
    container_name: prometheus
    image: prom/prometheus
    ports:
      - '9090:9090'

I rebuild grafana-image-renderer with
FROM node:14.1-alpine AS base
instead of node:14-alpine

and adding
RUN npm install -g npm-install-peers
after stage
RUN yarn install --pure-lockfile

here grafana-image-renderer config.json:

{
  "service": {
    "host": "0.0.0.0",
    "port": 8081,

    "metrics": {
      "enabled": true,
      "collectDefaultMetrics": true,
      "requestDurationBuckets": [1, 5, 7, 9, 11, 13, 15, 20, 30]
    },

      "console": {

    "maxDeviceScaleFactor": 4,

    "mode": "default",
    "clustering": {

      "maxConcurrency": 5
    },

    "verboseLogging": true,
    "dumpio": true,
    "timingMetrics": true
  }
}

I create and add all permissions to slack app

I use it webhook url in grafana notification channels settings and also set “include image”

There is no error logs in grafana container:

As a result in slack notifications there are no images

I’m sorry we’ve made you jump through so many hoops. I also appreciate your thoroughness with the issue. Grafana Alerting doesn’t currently include an image/visualization as the upgraded alerting system is no longer driven by association to dashboards and panels.

We will update our documentation to make this clear.

We also, have an open feature request here to bring back part of this functionality: Add "include image" option into ngalert · Discussion #38030 · grafana/grafana · GitHub - please vote and add your voice!
