Prologue One of the key features for the “GlueOps Platform” to work is installing a LoadBalancer, and because we’re using GlueKube to create kubernetes cluster in a cloud agnostic way, getting the LoadBalancer to work isn’t that easy, as each cloud providers requires different setup, especially for providers with no CCM or in an on-prem installation. The Birth of the LoadBalancer in the Kingdom of Kubernetes In the realm of cloud-native deployments, a Kubernetes LoadBalancer Service typically interacts with the underlying cloud provider’s infrastructure through a Cloud Controller Manager (CCM). When a Service of type LoadBalancer is declared, the CCM translates this request into a cloud-specific API call, provisioning a load balancer resource (e.g., an AWS ELB, a Google Cloud Load Balancer, or an Azure Load Balancer) in the respective cloud environment. This external load balancer then directs traffic to the Kubernetes worker nodes where the application pods are running. ...

During my research, I found Gitea, which I liked as it allows me to deploy all my projects on it and also host the containers. ...
