NAME

crate —

containerizer for FreeBSD

SYNOPSIS

crate crate-specification.yml

crate crate-file.crate

DESCRIPTION

The crate utility is a containerizer program that is able to create containers from container definition files, and then run containers as processes that have no dependencies besides system functions in the kernel.

Mechanism of action

crate uses FreeBSD jails to run containerized applications. It also uses ipfw(8)-based firewall rules to route network traffic in and out of containers.

Invocation

There are two basic operations that crate supports: create and run. When crate is invoked with a crate definition file (having the .yml extension), this triggers the create mode. When crate is invoked with a crate file (having the .create extension), this triggers the run mode.
