## Intro
Advanced Kubernetes YAML configurations & templates, based on my experiences running Kubernetes in production at different companies.
The top-level directory contains standard Kubernetes object templates with many Best Practices, Tips & Tricks learned over time across production environments.
The sub-directories contain ready-to-run real world apps that I've run across environments.
## Templates
Start with [deployment.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/deployment.yaml) / [statefulset.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/statefulset.yaml), for advanced users see [kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/kustomization.yaml).
The [service.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/service.yaml) and
[ingress.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/service.yaml) configs contain settings
for using static public IP addresses and locking down your cloud load balancer's firewall rules eg. to private IP
addresses, and patches for Cloudflare Proxied or VPN IPs. You may need to extend those IP lists to your office /
VPN / public addresses if really want to permit direct internet access to your ingresses and aren't proxying them
through a WAF in proxied mode etc.
See also the [Dockerfile](https://github.com/HariSekhon/Templates/blob/master/Dockerfile) template in the
[HariSekhon/Templates](https://github.com/HariSekhon/Templates) repo to containerize your custom apps for deploying
on to Kubernetes.
## Apps
Real-world app deployments are found in the more specific `/` directories.
These follow the standard Kustomize `/base/` and `/overlay/` layout to make it easy to use as-is by just tweaking a couple settings in the overlay to your specific environment.
## CI/CD
Advanced auto-scaling production-grade CI/CD on Kubernetes:
- [ArgoCD](https://argoproj.github.io/cd/) - deployment, configs and optimizations. Start here: [argocd/base/kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/argocd/base/kustomization.yaml)
- [Jenkins](https://www.jenkins.io/) - jenkins server and dynamically scaling agents on kubernetes. Start here: [jenkins/base/kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/jenkins/base/kustomization.yaml)
- see also: [Jenkins](https://github.com/HariSekhon/Jenkins) repo with advanced Jenkinsfile & Jenkins Shared Library
- [TeamCity](https://www.jetbrains.com/teamcity/) - teamcity server and dynamically scaling agents on kubernetes. Start here: [teamcity/base/kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/teamcity/base/kustomization.yaml)
- [Selenium Grid](https://www.selenium.dev/documentation/grid/) - simple and distributed auto-scaling deployments. Start here: [selenium-grid/base/kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/selenium-grid/base/kustomization.yaml) / [selenium-grid-distributed/base/kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/selenium-grid-distributed/base/kustomization.yaml)
## Helm Repos
Helm repos you should probably have installed:
| Repo Label | URL |
|------------------|-------------------------------------|
| stable | https://charts.helm.sh/stable |
| bitnami | https://charts.bitnami.com/bitnami |
| fairwinds-stable | https://charts.fairwinds.com/stable |
Table generated from [helm-repos.txt](https://github.com/HariSekhon/Kubernetes-configs/blob/master/helm-repos.txt)
by script [generate_repos_markdown_table.sh](https://github.com/HariSekhon/Kubernetes-configs/blob/master/generate_repos_markdown_table.sh)
and can be quickly installed via the script [install_repos.sh](https://github.com/HariSekhon/Kubernetes-configs/blob/master/install_repos.sh):
```shell
./install_repos.sh
```
## Helm + Kustomize integration
See [kustomization.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/kustomization.yaml) for 2 methods provided:
1. template the Helm chart using a `values.yaml` to Git and serve from there (see [DevOps Bash Tools](https://github.com/HariSekhon/DevOps-Bash-tools) for the `helm_template.sh` convenience script)
2. 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](https://github.com/HariSekhon/Kubernetes-configs/blob/master/kustomization.yaml).
## Production Ready Checklist

- Horizontal Pod Autoscaler - [horizontal-pod-autoscaler.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/horizontal-pod-autoscaler.yaml)
- Pod Disruption Budget - [pod-disruption-budget.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/pod-disruption-budget.yaml)
- Pod Anti-Affinity - stable vs preemptible, HA across AZs, see [deployment.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/deployment.yaml)
- Ingress Controllers - [Nginx](https://kubernetes.github.io/ingress-nginx/) ([config](ingress-nginx/base/)), [Kong](https://konghq.com/) ([config](kong/base/)) or [Traefik](https://traefik.io/traefik/) ([config](traefik/base/))

- App Lifecycle Management - [ArgoCD](https://argoproj.github.io/cd/) ([config](argocd/base/))
- App Ingresses - [ingress.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/ingress.yaml), `*/base/ingress.yaml`
- App Resources - see resources section in [deployment.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/deployment.yaml)
- App Right-Sizing - [Goldilocks](https://www.fairwinds.com/goldilocks) ([config](goldilocks/base/)) to generate VPAs and resource recommendations
- DNS - [External DNS](https://github.com/kubernetes-sigs/external-dns) ([config](external-dns/base/)) integration to AWS Route53, Cloudflare etc.

- Resource Quotas per Namespace - [resource-quota.yaml](https://github.com/HariSekhon/Kubernetes-configs/blob/master/resource-quota.yaml)

- Governance, Security & Best Practices - [Polaris](https://www.fairwinds.com/polaris) ([config](polaris/base/)) for recommendations
- Find Deprecated API objects to replace - [Pluto](https://pluto.docs.fairwinds.com/) - see [pluto_detect_kustomize_materialize.sh](https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/kubernetes/pluto_detect_kustomize_materialize.sh) and [pluto_detect_kubectl_dump_objects.sh](https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/kubernetes/pluto_detect_kubectl_dump_objects.sh) in the [DevOps Bash Tools](https://github.com/HariSekhon/DevOps-Bash-tools) repo
- Helm is not IaC idempotent by itself - that is PoC territory - you must wrap it in Kustomize, ArgoCD or similar to detect live drift!
- Quickly update any Helm Charts in a `kustomization.yaml` file using [kustomize_update_helm_chart_versions.sh](https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/kubernetes/kustomize_update_helm_chart_versions.sh) in the [DevOps Bash Tools](https://github.com/HariSekhon/DevOps-Bash-tools) repo

## Environment Enhancements
[.envrc](https://github.com/HariSekhon/Kubernetes-configs/blob/master/.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](https://github.com/HariSekhon/Templates) repo for more details on the `new` command to fast create new files from templates.

[argocd.d2](argocd.d2):
### OpenTSDB on Kubernetes and HBase
A high scale production OpenTSDB replatform I did to Kubernetes for a client, ingesting 9 billion data points per day and serving 3 million queries per day.
I also had to do advanced performance tuning of their production HBase cluster which was suffering from frequent outages at this scale due to being set up by a non-SME on the wrong hardware (I had to make do with the existing hardware of course).
This was the second client I did in-depth performance tuning of HBase for - I've published a selection of useful HBase tools - see `hbase_*.py` and `opentsdb_*.py` in my [DevOps Python tools](https://github.com/HariSekhon/DevOps-Python-tools) repo.
