You can use reference architectures to quickly and efficiently build out your MongoDB Kubernetes Operator infrastructure. These resources are opinionated, and as such, they are not in any way exhaustive of the wide range of potential deployment implementations. Instead, they are meant to serve as a practical reference and starting point as you work through the process of deploying or upgrading your MongoDB resources running in Kubernetes.
This documentation organizes reference architectures in distinct modules that you can combine and use as needed. Moreover, the reference architecture section includes all the information you need to stand up a tested, working deployment of each of the following implementations:
How to Execute
Each section of the reference architecture contains complete and working code snippets. If you would like to clone the source code to your local machine rather than copying and pasting from the guides directly, you can find it in the MongoDB Controllers for Kubernetes Operator repository.
git clone https://github.com/mongodb/mongodb-kubernetes.git cd mongodb-kubernetes git checkout 1.2.0 cd public/architectures
Each module contains a env_variables.sh file listing the required environment
variables. Before you can run any of the steps described within a given module,
you must first set the required variables. To do so, navigate to the module,
adjust env_variables.sh and run the following:
source env_variables.sh
To complete the procedures in most of the modules, you don't need check out the source code directly; you can simply copy and paste the provided code examples. However, in some cases (e.g. installing Istio Service Mesh), you need to navigate into the source code directory, because the steps execute some more complicated scripts that are not available to copy and paste.
Limitations
MongoDB Support doesn't provide assistance with third-party software. While each of the sections in the reference architecture is tested in each release of Kubernetes Operator, MongoDB support cannot extend to include assistance with tools that are not developed and released by MongoDB.
