Azure pipelines are also available in the GitHub marketplace and can be integrated with GitHub projects directly. You can choose GitHub as your project source and perform a build and release operation using an Azure pipeline. This also enables CI with GitHub; that is, as soon as there's a PR/commit based on your configuration, Azure pipelines will run build/release operations and report the status on the GitHub PR page so that the approver can review the CI/CD logs and approve the PR if it's appropriate.
Azure pipelines is available on the GitHub marketplace to purchase and use: https://github.com/marketplace/azure-pipelines. Alternatively, you can specify GitHub as a source in Azure DevOps and pipelines will be available for your GitHub repository.
