Prisma Cloud rules guide for Docker

This article provides a list of all rules and their intended behavior in Prisma Cloud Console UI. The purpose of this article is to help users better understand the intention of each rule in the Console and it’s corresponding effect on the host environment.

Running Docker commands through Defender

To access Docker daemon through Defender, you must explicitly specify Defender’s host and port. For example:

$ docker -H <DEFENDER_HOST_ADDRESS>:9998 run alpine

It is possible to make the management traffic between the Docker client and the Docker daemon flow through Defender by default via two environment variables. Those can be configured on a remote machine that accesses Docker daemon on some host (such as dev laptop), or the host itself for users who do not have root privileges (which should be the majority of users).

$ export DOCKER_HOST=tcp://<defender host address>:9998

$ export DOCKER_TLS_VERIFY=1

Once set, default calls to Docker flow through Defender (e.g., docker ps, docker run alpine). Throughout this guide however, in this guide, we have followed the default command without setting environment variables.
