Tutorials

Security using Calico Profiles

The above guide demonstrates Calico connectivity cross host, and how to limit that connectivity using simple Calico profiles. One profile is created for each network and the connectivity is defined as policy on each profile.

Security using Calico Profiles and Policy

The above guide digs deeper into advanced policy configurations for workloads. There is stil one profile created for each network but now the profiles define labels that are inherited by each container added to the network. The policy uses the labels in selectors to configure connectivity.

Security using Docker Labels and Calico Policy

The above guide demonstrates Calico connectivity between containers without using Profiles at all. Instead, Calico Policies are defined which apply to containers depending on the labels assigned to them at runtime. This allows policy adjustment at the container level rather than at the network level.

IPAM

This guide walks through configuring a Docker network for use with Calico and how to statically assign IP addresses from that network
