Advanced Kubernetes YAML configurations & templates, based on my experiences running Kubernetes in production at different companies.
Contains various Best Practices, Tips & Tricks learned over time in production environments.
Start with deployment.yaml / statefulset.yaml, for advanced users see kustomization.yaml.
The service.yaml contains config for using static public IP and locking down your GKE generated GCP firewall rules, Cloudflare proxied IPs etc.
Real-world app deployment examples, tuning and patches are found in the more specific <app>-kustomization.yaml
and <app>-*.yaml
configs.
Advanced auto-scaling production-grade CI/CD on Kubernetes:
- ArgoCD - deployment, configs and optimizations. Start here: argocd-kustomization.yaml
- Jenkins - jenkins server and dynamically scaling agents on kubernetes. Start here: jenkins-kustomization.yaml
- see also: Jenkins repo with advanced Jenkinsfile & Jenkins Shared Library
- TeamCity - teamcity server and dynamically scaling agents on kubernetes. Start here: teamcity-kustomization.yaml
- Selenium Grid - simple and distributed auto-scaling deployments. Start here: selenium-grid-kustomization.yaml / selenium-grid-distributed-kustomization.yaml
See kustomization.yaml for 2 methods provided:
- template the Helm chart using a
values.yaml
to Git and serve from there (see DevOps Bash Tools for thehelm_template.sh
convenience script) - dynamically load the Helm chart from upstream with a
values.yaml
...then patch override anything the chart doesn't directly support using the standard Kustomize patching examples given in the kustomization.yaml.
The best documentation links are provided at the top of each yaml for fast referencing (my advanced .vimrc can open these URLs from the current file via a hotkey!)
.envrc - use with direnv
to auto-load correct Kubernetes context isolated to current shell to avoid race conditions between shells and scripts caused by naively changing the global ~/.kube/config
context
Shortcut symlinks are for faster instantiation from these configs using the standard kubernetes shortcuts such as new pvc.yaml
- see the Templates repo for more details on the new
command to fast create new files from templates.
Forked from the DevOps Perl tools repo, this is now a submodule of the Templates repo which is a submodule of the DevOps Bash, Perl and Python tools repos.
