Using Podman Compose with Microcks: A cloud-native API mocking and testing tool
Microcks is a cloud-native API mocking and testing tool. It helps you cover your API’s full lifecycle by taking your OpenAPI specifications and generating live mocks from them. It can also assert that your API implementation conforms to your OpenAPI specifications. You can deploy Microcks in a wide variety of cloud-native platforms, such as Kubernetes and Red Hat OpenShift. Developers who do not have corporate access to a cloud-native platform have used Docker Compose.

This article discusses the barriers to getting Microcks to work with Podman and the design decisions we made to get around them. It includes a brief example of using Podman in rootless mode with Microcks.
