Watchtower: Customizable Verbosity for Slack Notifications

[iMerica]

It would be great to do a less noisy version of the Slack notifications.

Instead of this:

for container in containers:
   print [stopping|creating]  container ....

It would be great to to summarize this to:

All containers redeployed with latest image

Alternatively, simply bundle the "found new image - stopping - creating - removing" messages into a single message. That would already reduce the "spam" quite significantly, especially when using Mattermost which does not seem to bundle the messages automatially:

Ideally allow us to provide a template file (using go template syntax, similar to Alert Manager for Prometheus), to be able to define our own format. That would be extremely useful!

{{ if gt (len .Notifications.Updated) 0 }}
  {{ range .Notifications.Updated }}
    Container {{ .Annotations.container }} was updated with ({{ .Annotations.imageName }}) {{ .Annotations.imageHash }}.
    {{ .Annotations.deletedHash }} has been deleted.
  {{ end }}
{{ end }}
{{ if gt (len .Notifications.Failed) 0 }}
  {{ range .Notifications.Failed }}
    There was a failure: {{ .Annotations.Error }}
  {{ end }}
{{ end }}

And I would totally try to implement it and start a new PR, but my golang knowledge is not sufficient.

Bump up!?
Not a low priority for some of us! 😄

Not bugging though :)

I feel you, but I only have so many hours to put into open source each month.

It’s up for grabs though so if anyone want to take a stab at it; feel absolutely free. For now, however, I believe my time is better used elsewhere on the project.

Closing this issue in favor of #255 which is aimed towards a more generic (ie. not only for slack) solution.
