Webhooks

A webhook is a POST request sent to a URL that you define in Docker Hub or another registry. Use webhooks to trigger an action in response to an event such as a repository push.

This functionality is only available in Portainer Business Edition.

Webhooks are only available on non-Edge environments (environments running Portainer Server or Portainer Agent, not the Portainer Edge Agent). This is because the tunnel to the Portainer Edge Agent is only opened on-demand, and therefore would mean there is no way to expose a webhook permanently.

Enabling a container webhook

From the menu select Containers then select the container that you want to configure the webhook for.

In the Container details screen toggle the Container webhook option on. When the URL appears, click Copy link. This URL will be used to configure the webhook in your chosen registry.

This example shows how to trigger the webhook using redeploy:

<form action="https://portainer:9443/api/webhooks/638e6967-ef77-4906-8af8-236800621360" method="post">
  Redeploy with latest image of same tag <input type="submit" />
</form>

This example shows how to trigger the webhook to update the container to use a different image tag:

<form action="https://portainer:9443/api/webhooks/638e6967-ef77-4906-8af8-236800621360?tag=latest" method="post">
  Update container image with different tag <input type="submit" />
</form>

Configuring the webhook in Docker Hub

To finish the configuration, refer to Docker's own documentation.
