Pull images from container repository
Introduction
The Pull images from container repository plugin helps you poll the specified container repository and fetch the container images to deploy them on your target Kubernetes environments using Devtron's CD pipeline. By integrating this plugin you can:
Poll the designated container repository to get the specific container image build using external CI like Jenkins and Github actions. Once the image becomes available, you can deploy it to your target Kubernetes environment using Devtron's CD pipeline.
Currently, this plugin only supports ECR registry. Support for other container registries will be added soon.
