Use Cases with Examples
If you are using Docker Images for production so it is important to use verified Images which will give as security about the authenticity of the Docker Image. you can use DCT before publishing the images to public or private registries.
for example if you are using a NodeJS image of a specific version. so you can find there are lot’s of Images present in the docker hub. but if you want the as security so you need to use verified and official images you can also filter it on Docker hub.
Use cases of DCT
- DCT is used when you are building a project for personal use or for organizations collaboratively and only the team have the access to the Docker Image.
- when you working with an open-source programmed. so you can use DCT. maintainers can sign Docker images. and they use the signatures before publishing it to registry.
- DCT is also used with CI/CD pipelines to automate your workflow. the developers used it to build the image and before the deployment the system verify the image using signature.
- In DCT cryptographic signatures will be used a signer across the production will be used as a authentic and trustworthy source.
What Is Docker Trust Content ?
When we are using Docker images, we must think about whether the image we are using is trustworthy or not, because trust is a central concern in every field. especially when we download external resources from our local system. In this scenario, Docker comes up with a special security feature called Docker Content Trust (DCT).
