Continuous deployment
CD is the idea that code changes that successfully pass through your pipeline can be automatically deployed to a target environment. Although there are examples of continuously deploying to production, most enterprises prefer to target a dev environment. A gated approach is adopted to move the changes through the various stages of dev, test, staging, and finally production. CircleCI can facilitate gated deployment with approval workflows, which is covered later in this section.
In CircleCI, to deploy your image, we need to implement a deploy job. In this job, you can deploy to a multitude of targets such as Google Cloud Run, Docker Hub, Heroku, Azure, or AWS ECS. Integration with these targets will involve multiple steps. At a high level, these steps are as follows:
- Configure an orb for your target environment, which provides the CLI tools required to deploy your software.
- Store login credentials or access keys specific to the target...
