The IBM Kubernetes service free clusters consist of a single worker node with 2 CPU and 4 GB of memory for experimenting with Kubernetes. Unlike the fee-based service, these clusters do not include capabilities for application load balancing using ingress out-of-the-box. However, if you manage a DNS domain (any provider will suffice) and can add an A
record, it's possible for you to configure your own ingress that can provide http and https session termination for your containerized applications. Getting a TLS-enabled website or simply an external REST API couldn't be easier!
- Free IBM Kubernetes Cluster (IKS) - upgrade your account from Lite plan to create one. In the example commands, we'll assume that this cluster is named
mycluster
- kubectl - match your cluster API version (as of 12/5/20 - this is ~1.18.12)
- helm v3
- DNS domain that you can edit to configure
