A little over 6 moths in my current role as DevSecOps Engineer. Some days are the most uncomfortable I've felt in my life. This picture is a pretty accurate description of what it feels like learning some of the tools we use 😅 . But the knowledge and experience I’m gaining? 100% worth it.

I was productive yesterday - I spun up my first kubernetes cluster on my three node Proxmox cluster. The controller and 3x worker nodes are Rocky LXC containers.

The problem I'm attempting to solve is this monolithic beast of a docker host VM - it's running 12 containers and is struggling. I'm hoping to move to kubes to

  1. Learn kubes
  2. Distribute the workload across multiple physical hosts
  3. Limiting impact when one container hits high CPU/memory consumption

So far, I've successfully installed nginx ingress with cert-manager doing Let's Encrypt with cloud flare DNS proofs and direct container NFS mounts. I still need to figure out when/how to use persistent volumes/claims vs direct NFS mounts inside the container, and frankly I don't really grok labels/selectors/namespaces stuff.

Three windows: Foreground: console window showing the contents of index.html Middle distance: Synology window displaying the location of the index.html file Background: browser window showing the rendered index.html file from a kubes nginx poc container

Learn how to deploy a private #Docker registry on a Linode Kubernetes Engine cluster: linode.com/docs/kubernetes/how  via @leslitasalazar #LinodeDocs #LinodeK8s #LearnK8s

www.linode.comHow to Set Up a Private Docker Registry with Linode Kubernetes Engine and Object StorageIn this guide you will create a private Docker registry on Linode Kubernetes Engine where you can securely store your Docker images. Your Docker images will be stored in a Linode Object Storage bucket. You will use Let's Encrypt and cert-manager to create a TLS certificate for your private registry. To route your registry's traffic your will use the NGINX Ingress Controller and a Linode NodeBalancer. Finally, you will create a test deployment to ensure that your Linode Kubernetes Engine cluster can pull images from your Docker registry
