System requirements

Refer to these system requirements for your Continuous Delivery for Puppet Enterprise (PE) installation.

Hardware requirements

Before installing Continuous Delivery for PE, ensure that your system meets these requirements.

Installation architecture Memory Storage CPUs
Installation using disk object storage 8 GB 100 GB 4
Installation using external (Artifactory or Amazon S3) object storage 8 GB 50 GB 4

Supported operating systems

Continuous Delivery for PE can be installed on these operating systems. The Continuous Delivery for PE host server must run the same operating system and version as your Puppet master.

Operating system Supported versions
Enterprise Linux
  • CentOS
  • Oracle Linux
  • Red Hat Enterprise Linux (RHEL)
  • Scientific Linux
Ubuntu (General Availability kernels) 16.04 (on PE versions prior to 2019.8), 18.04

⛔ External databases

DEPRECATED: Support for MySQL and Amazon DynamoDB external databases is deprecated, and will be removed in a future release. Information on how to migrate your external database to a supported option will be provided before support ends.

External database Supported versions Notes
MySQL 5.7 Your MySQL database must use the latin1 character set and latin1_swedish_ci collation.
Amazon DynamoDB n/a Based on your usage, you might need to tune your tables' read/write capacity in order to reduce page load times.

Job hardware requirements

System requirements for your job hardware vary considerably based on the size of your Continuous Delivery for PE installation, the type of jobs you run, and how frequently you run them.

The size of the load placed on a job hardware server determines how robust that server's resources need to be. Determining that load involves a huge number of variables, from the number of jobs that run concurrently to the languages those jobs are written in. As a result, it's nearly impossible to provide one-size-fits-all system requirements for job hardware.

Instead, we've developed a sizing chart based on the estimated number of concurrent jobs a job hardware server is expected to regularly handle. While this chart represents our best estimates and understanding, it's provided only as a starting point. Testing and experience will help you fine-tune your job hardware and determine the optimum resource configuration for your installation's unique circumstances.

Estimated concurrent job load Memory Disk storage CPUs
2 - 4 concurrent spec tests 4 GB 100 GB 2
4 - 8 concurrent spec tests 8 GB 100 GB 4
6 - 12 concurrent spec tests 8 GB 100 GB 6
When setting up your job hardware, keep these facts in mind:
  • Disk storage requirements are minimal, and don't increase with added load. After a job run is complete, the job's log is passed to the object storage, and all data related to the job run is erased from the job hardware.
  • You can run more jobs concurrently without increasing CPUs, but the jobs will run more slowly.

Job hardware requirements for Docker-based jobs

To run Docker-based jobs, your job hardware must have a modern version of Docker CE or Docker EE installed. The puppetlabs/docker module is our preferred way to install Docker and keep it up to date.

Job hardware used for Docker-based jobs also requires internet access. If you're working in an air-gapped environment, set up an internal Docker registry by following the Docker documentation.
