Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

28.2. Composer System Requirements

Use a virtual machine to run Composer, because the underlying lorax tool performs a number of potentially insecure and unsafe actions while creating the system images. The environment where Composer runs should meet these requirements:
ParameterMinimal Required Value
System type
A dedicated virtual machine
2 cores
4 GiB
Disk space
20 GiB
Access privileges
Administrator level (root)
Off (permissive mode)
Connectivity to Internet and to a system with repository mirrors
Apart from the virtual machine that runs Composer itself, another system is needed to provide mirrors of Red Hat content delivery network (CDN) package repositories.


Composer is available as a Technology Preview. See the Technology Preview Features Support Scope for more details.
Customers deploying Composer are encouraged to provide feedback to Red Hat.
