This IP is the node's connection to the rest . Begin by choosing the Kubernetes version to use. When using interpolation to pass credentials from a digitalocean_kubernetes_cluster resource to the Kubernetes provider, the cluster resource generally should not be created in the same Terraform module where Kubernetes provider resources are also used. In addition, your cluster will eventually be upgraded if you stay on the oldest supported Kubernetes version for so long that DigitalOcean discontinues it entirely. The backend services were within a private network, such as 10.X.X.X ranges. We deploy Continue reading CO Charles Offenbacher CTO Reviewer Pros & Cons DigitalOcean Kubernetes DO Kubernetes is well-suited for: - deploying APIs- deploying workers- log collection and analysis (ie ELK stack)- deploying Helm charts and anything that can be mapped on to K8s concepts Less appropriate for anything requiring no public Internet access (ie VPC only).Less appropriate for anything requiring integration .
