Code integrity is extremely important, especially if you are running a cryptocurrency exchange.
Since HollaEx Kit is an open-source project, you can verify the code at any time by going to Github, but sometimes it's not enough. Internet is a wild jungle and you can't always trust what you download is what you intended to get.
Docker Content Trust is the savior in this context. It helps you to verify the image integrity. It has digital signatures signed by the issuers. By checking it, you can verify that the image is provided by the trustable issuers and that it has not been corrupted or tampered with.
Here's the way how you can check the image signature to check the image integrity
# To verity the integrity of a specific image
docker trust inspect --pretty hollaex/hollaex-kit:2.6.6

In order to enforce pulling ONLY the DCT signed images for extra security you can set the following command for docker:
