One of the most important component is the Docker Image store location. Due to security reasons you can have your microservices leaked!
There are several options for storing Docker images, and the best choice will depend on your specific needs and requirements. Here are a few popular options:
- Docker Hub: Docker Hub is a cloud-based registry service for storing and sharing Docker images. It provides a central place for organizing and managing your Docker images, and makes it easy to share images with others. Docker Hub is a good option for users who want an easy-to-use and cloud-based solution for storing their images.
- Private registry: A private registry is a self-hosted registry service for storing and sharing Docker images. It allows you to host your own registry on your own servers, giving you full control over the storage and management of your images. A private registry is a good option for users who want more control over their images and who don’t want to use a cloud-based service like Docker Hub.
- Amazon Elastic Container Registry (ECR): Amazon ECR is a managed registry service for Docker images that is integrated with Amazon Web Services (AWS). It provides a secure and scalable way to store and manage your Docker images, and integrates seamlessly with other AWS services. Amazon ECR is a good option for users who are already using AWS and who want a managed registry service.
Ultimately, the best option for storing Docker images will depend on your specific needs and requirements. You may want to consider trying out multiple options to see which one works best for you.
Here are a few best practices for using Docker Hub and alternatives:
- Use trusted base images: Start your Dockerfile with a base image from a trusted source, such as a trusted Docker registry or your organization’s internal registry. This will help ensure that your image is based on a secure and up-to-date foundation.
- Use descriptive and unique image names: Use descriptive and unique names for your Docker images, such as “my-company/my-application:latest”. This will make it easier to identify and manage your images on Docker Hub.
- Use tags wisely: Use tags to label and organize your images on Docker Hub. For example, you can use tags to differentiate between different versions of your image, such as “my-application:1.0” and “my-application:1.1”.
- Use automated builds: Use Docker Hub’s automated build feature to automatically build your images from a source code repository, such as GitHub. This will make it easier to maintain and update your images, and will ensure that your images are always up-to-date.
- Use a security scanner: Use a security scanner, such as Docker Bench for Security, to scan your Dockerfile and image for potential vulnerabilities. This can help identify any security issues that need to be addressed.
- Regularly update your images: Keep your Dockerfile and base image up-to-date with the latest security patches and updates. This will help ensure that your images remain secure over time.
