## A little about me and the past
|
||
|
|
|
||
|
|
- I work professionally as a "DevOps" engineer at Elsevier with a focus on Kubernetes and containers
|
||
|
|
- Previously a JavaScript developer, now a Go developer
|
||
|
|
- I've been running my own servers for as long back as I can recall (historically cheap VPS's with applications running either directly on the OS or using Dokku)
|
||
|
|
- I like to tinker with "Smart Home" stuff
|
||
|
|

## Kubernetes - local
|
||
|
|
|
||
|
|
**Primary Use**: Hosting sensitive or local-specific applications that I want to keep off the internet.
|
||
|
|
E.g.
|
||
|
|
|
||
|
|
- custom built CCTV monitoring application covering the 8 cameras I currently have set up
|
||
|
|
- automated download tools so I can kick off downloads remotely while I'm out
|
||
|
|
- DNS-based ad blocker (AdGuard)
|

**Primary Use**: Hosting internet facing services and providing a secure, authenticated tunnel to my local cluster
|
||

|
E.g.
|
||
|
|
|
||
|
|
- My personal blog plus some related sites
|
||
|
|
- Self-hosted alternatives to cloud services: Gitea, Nextcloud, Harbor, Photoprism, etc.
|
||
|
|
- Tekton - handle all my CI/CD needs, triggered by webhooks from Gitea
|
||
|
|
- "Utility" applications to make my life easier:
|
||
|
|
- Convert SVG to DXF - used when creating 3D print designs from SVG
|
||
|
|
- website-to-remarkable - lets me send a webpage as a PDF to my reMarkable tablet for later reading
