Convoluted Setup - Further deployment automation

[CommoDor64]

Hey all, thanks a lot for putting effort into this testbed setup, I would like to to start a discussion regarding developer experience.

What's wrong?

Lot's of manual processes can be automated using proper scripts or proper server config and provision systems (Ansible / Terraform). I had colleagues struggling with setting up the testbed. Despite using cloud methods, "Cloud Native" mindset is not present and the setup is much messier than is should be imho.

Solution

• Make the scripts "sane" - embedding k8s resources into bash scripts as strings seem sloppy
• Perhaps bundling the RIC into a properly made helm chart
• Setup of xApp with an external Ngnix server only to server config is not a great solution in my book
• Using ansible / puppet / Terraform to have a fully automated setup

What do I propose?

• I can submit a PR that lay out what I have in mind. My current setup is much friendlier and less prone to errors.

Sorry for the late reply. This might be better in a discussions chat but i will share some thoughts here. The way the deployment happens now is intentional due to its flexibility. This does not mean there are not issues that prove to be annoying in certain situations. Most of the issues come from script issues from what i am aware of. Do you have your solution uploaded on your github that we can test? How easy would it be to offer newer releases in this setup? The nginx solution is not needed when using the dms_cli tool.

I understand the flexibility coming with just providing a bash scripts and instructions. However - the cloud community converges slowly around standard solution.

Terraform plugin exist for almost any cloud platform, also on premise. Ansible abstracts the need for a manual labor here.

Warning, this solution was quick and dirty, and was meant to allow people to install all semi-automatic. It uses Ansible (playbook). But I had ideas for a full Terraform setup with machine provisioning

P.S I don't understand why a cli is needed for a such a standard thing? The dms_cli needs to be maintained, versioned, etc. And there are no super complex configurations in the end of the day
