Air-gapped Installation of Application Images

Learn how to manage application images in air-gapped environments. Following are the five different options you can use to ensure your application images are available in air-gapped environments.

Configure HTTP2 for Release

This topic illustrates how to configure the settings required to install Release with HTTP2 backend enabled on a Kubernetes cluster.

Install or Upgrade Digital.ai Release on an Air-gapped Environment

You can install Release in an air-gapped environment disconnected from the public internet. This topic provides information about installing and upgrading Release in such environments using a Minikube cluster and a custom image registry. For other Kubernetes platforms, steps are similar to the ones listed here for Minikube as long as the custom image registry contains all the required images.

Install the XL CLI

This topic describes the system requirements, installation, and syntax for the XL Command Line Interface (XL CLI) used to support Digital.ai DevOps as Code and blueprints features.

Install—Deploy or Release—On-premise Kubernetes

Important: Use these instructions to install Digital.ai Deploy or Release on a minikube multi-node cluster for testing or illustration purposes. Do not use these instructions to set up a production environment.

Manual upgrade PostgreSQL

PostgreSQL cannot be automatically upgraded during an operator-to-operator or Helm-to-operator upgrade due to incompatible data formats between different PostgreSQL server versions. In such cases, a manual upgrade is necessary. The process involves first backing up the PostgreSQL data, then upgrading to the new PostgreSQL version, and finally restoring the data in the upgraded version.

Manual upgrade RabbitMQ

RabbitMQ during operator2operator upgrade or helm2operator upgrade to version 23.3 of operator will not upgrade automatically to the latest RabbitMQ server version.

Plan Your Installation or Upgrade

You use the XL CLI's xl kube command to install or upgrade Digital.ai Deploy or Release, or Release Runner. For more information, see XL Kube Command Reference.

Production Environment Installation

This topic describes how to set up Release in a production environment. It describes how to configure the product, environment, and server resources to get the most out of the product. This document is structured in three sections:

Setup Custom Image Registry

In this article, you will learn how to set up a custom image registry to install or upgrade Release. A custom image registry can either be public (not password protected) or private (password protected).

Store Reports and Logs on S3—Kubernetes

This topic describes how to configure Digital.ai Release on Kubernetes to store reports and task logs on Amazon S3. This setup eliminates the need for persistent volumes, making storage management easier for Kubernetes-based release instances.

Using an Existing PostgreSQL Database

If you plan to use an existing database—one that is not created by default by the Operator-based installer—you must configure the relevant database parameters in the dairelease_cr.yaml file.

Using an Existing PostgreSQL Database

If you plan to use an existing database—one that is not created by default by the Operator-based installer—you must configure the relevant database parameters in the dairelease_cr.yaml file.

Using an Existing RabbitMQ Message Queue

If you plan to use an existing message queue — one that is not created by default by the Operator-based installer — you must configure the relevant MQ parameters in the dairelease_cr.yaml file.

Using an External Database

This topic illustrates how to use an external database instead of the one that is provided with the operator itself.

Using an External Message Queue

This topic illustrates how to use an external message queue, instead of the RabbitMQ that is provided with the operator itself.

Using Secret References in CR

This topic illustrates how to replace the CR values that are in clear-text format in the CR with the secret references.

XL Command Line Interface reference

The xl command line tool provides a fast and straightforward method for provisioning Digital.ai Release, Deploy, and Runner servers using YAML files. The YAML files can include items such as releases, pipelines, applications, infrastructure, and target environments. In addition, the XL CLI is used for installing or upgrading Digital.ai Deploy and Release.
