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. Each image is scanned by trivy to ensure they contain no known CVE vulnerabilities before promotion to Docker Hub.
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)
- Keycloak for OpenID / OAuth2 user authentication / authorization
- 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
