Very approachable explanation how Union File Systems work used by #Docker #Container images. https://t.co/Rh5Qiyrivm

[Simon Pirschel @aboutsimon]

Trouble with small interactive terminal windows in #Docker #container? "reset -w" in container, closing and reopening the session will scale to full size.

Finally an enterprise ready #container image registry. "apt purge nexus-oss" ;) @project_harbor https://t.co/xCm2Flc7oq

CRI Runtimes Deep Dive: Who's Running My Kubernetes Pod!? Good talk by @estesp about #Kubernetes, #Container Runtimes and #containerd as well. https://t.co/qpgiAWh1Qc

[Simon Pirschel @aboutsimon]

Since #containerd 1.1 nativly supports #Kubernetes CRI I figured "Why not replace #Docker ?" This is a quick #howto on how to use #K8s with containerd 1.1 and #runc. https://t.co/6uHO1pp7fY

#Google #GCP The Good, Bad, and Ugly, good read 👍https://t.co/DTrNpsLSP7

HA support finally arrived in #kubeadm with the #Kubernetes 1.11 release. https://t.co/ftY5u3mTD5

[Simon Pirschel @aboutsimon]

Probably the best feature of #Kubernetes 1.11 IPVS support for kube-proxy. Moving away from hacky iptables rules to rock solid tech made for load balancing. https://t.co/IfwPu8A6i9

kube-state-metrics provides you a ton of state information about your #Kubernetes cluster, like kube_deployment_status_replicas_unavailable for your #Prometheus monitoring https://t.co/b3FEw57Kuj

#Helm 3 says goodbye to Tiller 👍 Many sweet changes! But #LUA? Arrays start with index 1 in LUA, that's the devils work! 😱 https://t.co/yddQQ2BtHD #Kubernetes

How to test if your #Kubernetes label selector is working: kubectl get pods --selector=app=myapp,env=dev

"The problem I see with #Kubernetes is that the cognitive load in the early parts of a project are simply too high." The most critical factor after the hype, simplicity. https://t.co/aUkh4hI8Mc

[Simon Pirschel @aboutsimon]

Need to debug #DNS in a #Kubernetes #Pod and no DNS utils available? Try Python: python -c 'import socket; print(socket.gethostbyname("kube-dns"))'
Try getent: getent hosts kube-dns

[Simon Pirschel @aboutsimon]

Really exited about the efforts of the https://t.co/r2L5EbdULq #Kubernetes project. This will greatly reduce cluster setup/management cost and make #K8s much more accessible. Hopefully also consolidate the installer jungle.

[Simon Pirschel @aboutsimon]

Just finished a basic #Kubernetes #PodSecurityPolicy guide, check https://t.co/9Z1B8t7wNa for introducing PodSecurityPolicies in your #K8s cluster
