Our GitHub integration does the following: - Installs the app for webhooks - Post back check status on each commit when we run the build - Adds a comment on each PR with the Coherence preview URL - Auto-creation of features from Github pull requests. Enable "Create Preview via Pull Requests in the Settings tab in Coherence and when we receive a webhook from github about a pull request in your repo for a branch that is not present in Coherence, we will create a new Preview environment, submit a build, and leave a comment with a link the Preview on your pull request.

Docker Hub

Docker Hub enforces rate limits on unauthenticated image pulls. - On GCP, Google runs a caching proxy that hides this problem from you. - On AWS, CodeBuild project executions use shared IPs and by default you will be rapidly rate limited using public images hosted by Docker in your account. - Coherence hides the problem by using a Coherence-provided Docker Hub account that has increased rate limits, to pull images more frequently. However, this still leaves you vulnerable to our account being used aggressivly by other applications. Therefore, we also allow you to provide your own Docker Hub credentials to be used in your build pipelines. - To provide your Docker Hub credentials to your pipelines, you just need to set the Environment Variables DOCKER_USERNAME and DOCKER_PASSWORD. Like all variables, these can be the project-level default scope, or per-environment scope.
