The gap this fills: Docker Hub doesn't ship an official Discord app. If you want image push to show up in Discord the moment it happens, the usual options are a paid third-party bot, custom code, or routing everything through a $20–50/month automation platform just to move one webhook from one URL to another. ZestyGlue does exactly that one thing for $9/month.
What it looks like
ZestyGlue
Docker Hub — Image Pushed
myorg/myapp:v1.4.0
pushed by myorg
A real Docker Hub event, shown as ZestyGlue formats it for Discord.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new Docker Hub → Discord connector. You'll get a unique webhook URL right away.
- Point Docker Hub at it. In your repository, go to Webhooks, and paste in your ZestyGlue webhook URL. That's the only setting — Docker Hub's webhooks have no secret to configure.
- Point Discord at ZestyGlue. In your target channel, go to Edit Channel → Integrations → Webhooks → New Webhook, copy its URL, and paste it into ZestyGlue.
Tip: Docker Hub's webhook fires on every push to the repository, including automated CI pushes — if you only want to know about release tags, consider a second repository just for tagged releases.

Questions
Does this work for private repositories?
Yes — Docker Hub's webhook feature works the same for private and public repositories, as long as you have admin access to configure it.
Will this fire for automated builds, not just manual pushes?
Yes, any push triggers the webhook, whether it came from docker push, a CI pipeline, or Docker Hub's own autobuild feature.
Can more than one person see these messages?
Yes — anyone in that Discord channel sees every event as it arrives, exactly like a message from a bot.
What happens if my ZestyGlue subscription lapses?
Events are silently dropped rather than causing errors on Docker Hub's side — Docker Hub never sees a failure response, so it won't retry aggressively or flag your webhook as broken. Your dashboard will simply stop showing new events until you resubscribe.
