Trying to write container name in the notification

[lubomben]

I am trying to write in the notification (via PushOver) the container name where the image wa updated.

I use the following docker-compose.yaml file:

version: '3.5'

services:
  diun:
    image: crazymax/diun:latest
    container_name: diun
    command: serve
    volumes:
      - ./data:/data
      - ./diun.yml:/diun.yml:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      - TZ=Europe/Rome
      - LOG_LEVEL=info
      - LOG_JSON=false
    restart: always
    labels:
      - "diun.enable=true"
      - "diun.metadata.container=diun"

and this is the notif section in my diun.yml file:

notif:
  pushover:
    token: <OMITTED>
    recipient: <OMITTED>
    templateTitle: |
      {{ .Entry.Image }} {{ if (eq .Entry.Status "new") }}is available{{ else }}has been updated{{ end }}
    templateBody: |
      Docker tag {{ if .Entry.Image.HubLink }}[**{{ .Entry.Image }}**]({{ .Entry.Image.HubLink }}){{ else }}**{{ .Entry.Image }}**{{ end }} which you subscribed to through {{ .Entry.Provider }} provider {{ if (eq .Entry.Status "new") }}is available{{ else }}has been updated{{ end }} on {{ .Entry.Image.Domain }} registry (container: {{ .Entry.Metadata.Container }}).

Note the part "(container: {{ .Entry.Metadata.Container }})" at the end on templateBody.

Following is the message in the notification:
Docker tag docker.io/diun/testnotif:latest which you subscribed to through file provider is available on docker.io registry (container: ).
Note the part "(container: )" at the end of the message where I supposed there should be the container name from the field ".Entry.Metadata.Container".

Yes, tried to put in diun.yml the following from the example to test:

templateBody: |
      Docker tag {{ .Entry.Image }} which you subscribed to through {{ .Entry.Provider }} provider has been released.

      {{ range $key, $value := .Entry.Metadata }}
      * `{{ $key }}`: `{{ $value }}`
      {{- end }}

But I got this in notification:
Docker tag docker.io/diun/testnotif:latest which you subscribed to through file provider has been released.

Just a note, don't know if it's important: I use the following command to test:
docker compose exec diun diun notif test

It seems that it does not iterate the metadatas... or that there are no metadatas.

Yes, tried to put in diun.yml

Hard to know without the full yaml. Can you post it?

docker compose exec diun diun notif test

Ah right, the notif test cmd does not read or set any metadata. You need to test it "live" with your notif provider.

docker compose exec diun diun notif test

Ah right, the notif test cmd does not read or set any metadata. You need to test it "live" with your notif provider.

I supposed about it and then I have another question... Can I force somehow the check on a container abount a new image availability or I have to wait for it? I am trying how to force this behaviour but I can't find a way... any advice is welcome :)

here it is:

watch:
  workers: 10
  schedule: "0 */6 * * *"
  healthchecks:
    baseURL: https://hc-ping.com/
    uuid: <OMITTED>

providers:
  docker:
    watchByDefault: false
    watchStopped: false

notif:
  pushover:
    token: <OMITTED>
    recipient: <OMITTED>
    templateTitle: |
      {{ .Entry.Image }} {{ if (eq .Entry.Status "new") }}is available{{ else }}has been updated{{ end }}
    templateBody: |
      Docker tag {{ if .Entry.Image.HubLink }}[**{{ .Entry.Image }}**]({{ .Entry.Image.HubLink }}){{ else }}**{{ .Entry.Image }}**{{ end }} which you subscribed to through {{ .Entry.Provider }} provider {{ if (eq .Entry.Status "new") }}is available{{ else }}has been updated{{ end }} on {{ .Entry.Image.Domain }} registry (container: {{ .Entry.Metadata.Container }}).

I confirm that "live" test worked.

However I used the predefined "{{ .Entry.Metadata.ctn_names }}".

My custom field {{ .Entry.Metadata.Container }} from label "diun.metadata.container=diun" do not work. I will investigate.

[crazy-max]

{{ .Entry.Metadata.Container }} from label "diun.metadata.container=diun"

Seems there is a typo. Should be {{ .Entry.Metadata.container }}

[lubomben]

My mistake! I didn't know that is case-sensitive. I will do further tests.

Thank you very much for you support!
