Set Up Tools to Make DOKS Cluster Operationally Ready

DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains, integrate natively with DigitalOcean Load Balancers and volumes, and can be managed programmatically using the API and command line. For critical workloads, add the high-availability control plane to increase uptime with 99.95% SLA.

You can set up a variety of tools to make your DigitalOcean Kubernetes (DOKS) cluster operationally ready. Your operationally-ready DOKS cluster can have a set up as shown below, which includes:

• Setting up an ingress controller using Ambassador or nginx

• Installing apps such as Prometheus to monitor the cluster

• Installing apps such as Loki to aggregate logs

• Configuring backups and restoration using Velero or Trilio

This tutorial series consists of three parts:

DOKS Operational Readiness, Part 1: Install the NGINX Ingress Controller

Install the NGINX ingress controller and configure HTTP rules for the two deployed backend services.

DOKS Operational Readiness, Part 2: Enable HTTPS

Configure production-ready TLS certificates with Cert-Manager using the HTTP-01 challenge.

DOKS Operational Readiness, Part 3: Configure Wildcard Certificates

Configure production-ready TLS certificates with Cert-Manager using the DNS-01 challenge to support wildcard certificates.
