Why use KuberLogic?

The ultimate goal of KuberLogic is to provide an easily accessible service to turn any containerized application into a cloud-native SaaS solution.

KuberLogic:

• Provides a straightforward and reliable way to deploy and manage application instances (Tenants) while achieving maximum resource utilization and standardization;
• Simplify migration to multi-tenancy using industry-standard containers & K8s and allows rapid migration to SaaS with minimal application modification;
• Gives independence and frees from vendor lock, as KuberLogic is open source and based on Kubernetes to provide a consistent platform anywhere

Requirements

Kubernetes cluster 1.20-1.23

KuberLogic cert-manager issue

Kindly help me out

Is kuberlogic compatible on AWS EKS?

Hello,

I was wondering if KuberLogic is compatible with AWS EKS v1.20? I ran the installer and received an error that states that the cluster is not compatible.

Installation problems

When running kuberlogic install i get the following error:

Waiting for Kuberlogic to be ready...
error: timed out waiting for the condition on deployments/kls-controller-manager

I am running minikube. This is a fresh environment with plenty of resources.

Tls installation cert/key flags failure on a first run

If you specify path to tls cert/key in kuberlogic install command - it will fail, because kuberlogic trying to cache certs in ~/.config/kuberlogic/cache/config/certificates/ directory, which doesn't exists.
I did installation step-by-step from getting-started guide

For example:

➜  kuberlogic install --non-interactive --tls_crt ca.pem --tls_key ca-key.pem --docker_compose docker-compose.yml                                          
Preparing KuberLogic configs...Error: failed to cache tls.crt: open /home/username/.config/kuberlogic/cache/config/certificates/tls.crt: no such file or directory       
➜  ls -l ~/.config/kuberlogic/cache/config/

First look on this project

Thank you for developing this great tools!
I see potentials for kuberlogic to manage saas application and it could be a game changer.
After some trial, I have few questions on it

• I can apply kuberlogic install command to install kuberlogic in my cluster properly, but it will be even better if there is a way to install kuberlogic declaratively, like via kustomize. One way I think about is to add some detailed documentation on the usage of make deploy or kustomize build config/default | kubectl apply -f -.
• 2 LoadBalancer services are created after installation: api-server and chargebee-integration. It would be some concern to expose 2 more LoadBalancer. I would prefer to expose there under ingress
• May I opt out chargebee from the default installation? It will be even better if there is a thing like billing provider interface(via a new CRD? idk), so that we can implement our own billing provider
• For pod workloads, I see hostaliases was set to 127.0.0.1, so that containers can call other containers with localhost. But in my experience, the docker-compose workload will call other containers by service names under same compose network. I feel a little bit weird when I first time use it.
• About node selector, it will be great if I can add node affinity/selector on app creation, so that I can choose which node to provision specific apps
• For application pause, application would become pending if I set paused: true in kuberlogicservice.spec, but I can't find equivalent operation in restapi or cli. May I know if it is a proper way to stop a running application?

This project looks really great! Although I am not a expert on golang or k8s operator, I will be glad if I am able to make more contributions on it!

Exactly what I've been looking for!

Thanks for this project. I have a single tenant app that needs to be Kuberlogic-ified. I tried to follow what Mattermost did to saasify their single-tenant app and it was quite complicated.

The app is: https://www.getlago.com/ Actually, it's billing app like Chargebee and Stripe billing. I've talked to them about making this Saas and they're ok with it as long as I share the code I use to build it. We're all good. I also have access to SaasRocks in case that's required for any front-end stuff. My Saas will be called: billstreams.com Cheers, Dave
