Kubernetes

As one of the first adaptors of Kubernetes, I have learned the hard way to install, upgrade and maintain Kubernetes. Kubernetes can simplify a lot of your infrastructure and development pipeline but it is not THE solution for each project.

My experience of Kubernetes ranges from installing and managing it the-hard-way, a cluster on AWS, GCE or DigitalOcean or provisioning a cluster using Ansible or Puppet.

Kubernetes tasks

  • Cluster installation and configuration (by using kubeadm, Puppet, Ansible)
  • Periodic maintenance, upgrades, security checks
  • Setting up high availability (multiple master nodes, etcd cluster)
  • Implementing GitOps solution like Weave Flux or ArgoCD
  • Troubleshoot issues on networking, scheduling, storage, container, crashes and more
  • Integrate monitoring, logging and alerting with Prometheus and Nagios
  • Automated deployment pipeline with Gitlab, Jenkins or other CI tool (see also CI/CD)
  • Tighten security with RBAC rules, network policies and pod security policies
  • Service mesh insight and control with Istio or Linkerd
  • Integrate with your cloud provider or hypervisor (VMWare, DigitalOcean, GCE, AWS)
  • Implement persistent storage (cloud volumes, object storage, NFS, Ceph)
  • Implement automated backup
  • Writing or customize Helm charts
