This wiki and the ahr code repository are a collection of materials developed by GCP/BAP Customer Success team. It reflects team's experience acquired during hybrid engagements.
Its goal is to facilitate knowledge transfer and best practices around installation, operations, and troubleshooting of Apigee Hybrid product.
The AHR utility complements officially provided apigeectl utility and encapsulates additional tasks that optimise operational experience.
The AHR Wiki complements Apigee Hybrid documentation and contains walkthrough tutorials, concept guides, and troubleshooting articles that cover variety of specific scenarios that go outside of scope and remit of an official documentation.
The expected target audiences of the ahr and ahr wiki are:
-
users installing Apigee hybrid first time; expediting success rate by following specific end-to-end walkthrough tutorials;
-
users that wish to have a better knowledge of operating hybrid prerequisite components like ASM/Istio ingress gateway;
-
details of private cluster setups;
-
multi-cloud setups, including networking, and VPN connectivity;
-
devops engineers interested in automation of hybrid installations, performance testing, etc.
By introducing a layer of abstraction over apigeectl overrides .yaml config files, we can simplify:
-
DevOps Automation: Create a single-command CD/CD for Performance Test that would a) install Runtime; b) deploy proxies; c) execute tests d) collect outputs e) destroy test environment;
-
Configuration Complexity: non-trivial multi-region, multi-cloud installations;
-
Study tool: Capture best practices, as well as tips and tricks
-
Executable documentation
The scripts are meant to be read and consulted to observe how to implement required steps. You will need them for your authomation (ie, CI/CD scripts)
-
Be intuitively compatible with a manual installation process
The collection of ahr-* scripts and their options are tasks that are the high-level process of Hybrid installation process.
-
Templating
For cluster config and runtime config file we cannot provide generic enough file to cater for all eventualities. Therefore we provide a templating mechanism that lets you create any desired configuration.
-
Full explicit paths -- removes a current-directory ambiguity
-
Copy-Paste-friendly commands -- via usage of environment variables
-
Look at the right-hand contents pane and chose a deployment scenario closest to your environment.
-
Follow the walkthrough.
-
Look under-the-hood: open ahr-*-ctl commands and libraries and see how things are implements; compare and contrast it with hybrid documentation.
-
Explore Troubleshooting and Concept sections to dig deeper.
-
Visit GKE/AKS Multi-cloud installation walkthrough to experience complex deployment scenario requirements.
* AHR-the-utility logo alludes to another AHR, Aryl Hydrocarbon Receptor, protein that in humans is encoded by the AHR gene. See "You AhR What You Eat: Linking Diet and Immunity" [1]; 3
There is a number of traits that draw the parallel between ahr the utility and ahr the protein.
-
It is useful during CI/CD Ops development. "In terms of evolution, the oldest physiological role of Ahr is in development."
-
It complements kubectl, istioctl, and apigeectl in its adaptive function. "The adaptive response is manifested as the induction of xenobiotic metabolizing enzymes"
-
It helps dealing with toxic aspects of bugs and errors while troubleshooting and debugging. "Extensions of the adaptive response are the toxic responses elicited by Ahr activation." [2]
