Kubernetes

As one of the first to adopt Kubernetes in production, nowadays I am still very happy with the vast amount of problems Kubernetes can solve. My knowledge of Kubernetes is as wide as installing it the-hard-way to start a single-press-on-the-button cluster on AWS, GCE or DO.

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
