Practical Docker Tools

Kubernetes is hard--or is it? This repo is a collection of multi-platform images and container resource definitions for managing a software-dev organization using Kubernetes. These tools make it easy. Contents:

Directory Description
ansible build your own cluster (Kubernetes or Swarm)
images images which are published to Docker Hub
k8s container resources in kubernetes yaml format
lib/build build makefile and tools
services non-clustered docker-compose services
ssl PKI certificate tools (deprecated by k8s)
stacks container resources in docker-compose format

Find images at docker hub/instantlinux. Find a lot more details about the Kubernetes bare-metal installer in k8s/README.

Kubernetes capabilities

The cluster-deployment tools here include helm charts and ansible playbooks to spin up bare-metal or VM master/worker nodes, and a Makefile to add several additional features.

  • Direct-attached SSD local storage pools
  • Dashboard
  • Non-default namespace with its own service account (full permissions within namespace, limited read-only in kube-system namespaces)
  • Helm3
  • Mozilla sops with encryption (to keep credentials in local git repo)
  • Encryption for internal etcd
  • MFA using Authelia and Google Authenticator
  • Calico or flannel networking
  • ingress-nginx
  • Local-volume sync
  • Pod security policies
  • Automatic certificate issuing/renewal with Letsencrypt
  • PostgreSQL-operator from CrunchyData
