Refer to these system requirements for your Continuous Delivery for Puppet Enterprise (PE) installation.
Hardware and port requirements
Before installing Continuous Delivery for PE, ensure that your system meets these requirements.
While Continuous Delivery for PE can be installed on a single server, installing on three servers is recommended to provide redundancy in case one server becomes unavailable.
Each server must meet the following minimum requirements:
||8 (or equivalent)|
/opt/replicatedto support the increased load on the system.
Open port requirements
|Continuous Delivery for PE ports|
|443||TCP||Web UI||Browser||Continuous Delivery for PE|
|8000||TCP||Webhook service||Source control||Continuous Delivery for PE|
|2379||TCP||High availability (HA) communication||etcd on the Kubernetes host||etcd on the Kubernetes host|
|6443||TCP||Kubernetes API||Admin workstation||Kubernetes host|
|6783||TCP/UDP||Kubernetes networking - Weave||Kubernetes host||Kubernetes host|
|8800||TCP||Platform admin console||Admin browser||Kubernetes host|
|9001 (offline installations only)||TCP||Local registry for offline installations||Job hardware||Kubernetes host|
|10250||TCP||Kubernetes cluster management||Kubernetes host||Kubernetes host|
IP address range requirements
IP address ranges
must be locally accessible. See Resolving IP address range conflicts for instructions.
Supported operating systems
Continuous Delivery for PE can be installed on these operating systems.
|Operating system||Supported versions|
|CentOS||7.4, 7.5, 7.6, 7.7, 7.8, 7.9
|Red Hat Enterprise Linux (RHEL)||7.4, 7.5, 7.6, 7.7, 7.8, 7.9
|Ubuntu (General availability kernels)||16.04 (on PE versions prior to 2019.8)
Antivirus and antimalware considerations
Antivirus and antimalware software can impact Continuous Delivery for PE or prevent it from functioning properly.
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|
- 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
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.
Supported Puppet Enterprise versions
The following versions of Puppet Enterprise (PE) are supported for use with Continuous Delivery for PE.
For more on PE versions, see Puppet Enterprise support lifecycle.
PE version-specific feature limitations
- Impact analysis reports for module code are supported on PE 2018.1.9 and newer versions in the 2018.1 series, and on all supported versions in the PE 2019.x series.
- Hiera support for impact analysis reports is supported on all supported versions in the PE 2019.x series.
The following browsers are supported for use with the Continuous Delivery for PE web UI.
|Google Chrome||Current version as of release|
|Mozilla Firefox||Current version as of release|
