Prisma Cloud Rules Guide - 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.
About this reference environment
This guide is designed as a reference document for all access rule policies enlisted in Prisma Cloud Console and their intended affect on host environment.
These commands are run from a Docker client to a Prisma Cloud Defender using the access control feature.
Access control rules can be configured at
Defend > Access > Docker
.We have organized this document using the same structure as the Prisma Cloud product UI, which follows the structure in the Docker Remote API documentation.
Note that there may be minor differences in the structure as the Docker Remote API evolves; this document is currently aligned with the documentation for API v 1.24 and will be updated periodically with new releases.
For understanding purposes all rules are set to deny and their corresponding influence on host environment is recorded.
