![]() Axibase Collector JSON Job Documentation.In the example below, the status is -1, reported as ! Error by Docker Hub. The build fails if the status is not 0 ( Queued), 2 or 3 ( Building), or 10 ( Success). The history is also available via Docker Hub v2 API. Images that are uploaded by external tools are out of scope. History is only available for automated builds. Your team needs to fix these failures regardless of the cause.Īccess build history, containing success and failure statuses, under the Build Details tab in Docker Hub. # Build Failuresīuild failures come in different flavors - some are caused by human error while others occur due to infrastructure changes outside of human control. Note that this solution only applies to automated builds which are executed by Docker Hub itself. This guide describes a solution, based on the Rule Engine implemented in Axibase Time Series Database (ATSD), which polls the Docker Hub build history using the Docker Hub v2 API and generates missing webhooks in case of build failures or if the build is queued for more than one hour (you can configure this threshold). Also, Docker Hub does not dispatch an email alert when the build remains queued for a long period of time. While the email option serves as a workaround for build failures, do not rely on it for programmable integration with alerting and CI systems. This limitation is known but a fix is not yet available. If the job fails or becomes stuck at Queued status, Docker Hub does not fire webhooks and your team remains unaware of broken builds. While the Docker Hub provides the capability to trigger outgoing webhooks, the webhooks only execute when the automated build completes successfully. If you have images hosted on the Docker Hub registry, you need to monitor automated build jobs on Docker Hub to ensure that the images you successfully publish new images and your CI pipeline remains healthy. # Generate Webhook when Docker Hub Build Fails # Overview
