What is Docker Content Trust (DCT)?
Docker content trust (DCT) is a security functionality provided by the Docker. it verifies the authenticity of Docker images by using some security concern techniques like cryptography keys. It lowers the possibility of harmful or unauthorized alterations to the container images. and DCT makes sure that they come from an authorized source and have not been altered and it also enhances the security within the containerized environments. DCT keys play an important role for enhancing the security.
How to Use Docker Content Trust to Verify Docker Container Images
The world of containerized applications is based on trust. You rely on Docker images to be exactly what they say they are: secure, reliable, robust, and built with the right elements. But just like you can not just blindly trust any random ingredient in your kitchen, similarly the Docker image needs a kind of verification so we don’t need to be concerned about security issues.
DCT is an essential feature for your Docker container security. It allows you to focus on building and deploying amazing applications, while it takes care of the critical tasks of ensuring security.
