Accessing Rancher cluster I was doing update on Kubernetes cluster I had not touch in a while when I noticed weird behaviour: the output of get command was incomplete the -o wide option had no effect on the command output (IP addresses are masked) ➜ .kube git:(master) ✗ kubectl --kubeconfig dropship-dev-uat get nodes NAME AGE ip-172-xx-xx-xx.ca-central-1.compute.internal 613d ip-172-xx-xx-xx.ca-central-1.compute.internal 628d ip-172-xx-xx-xx.ca-central-1.compute.internal 558d and ➜ .kube git:(master) ✗ kubectl --kubeconfig dropship-dev-uat get nodes -o wide NAME AGE ip-172-xx-xx-xx.

Accessing Rancher cluster After creation, you can access the K8s cluster running Rancher by saving the config file available from the console and using standard kubectl command kubectl --kubeconfig ./quickstart.kubeconfig get pods --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE cattle-system cattle-cluster-agent-5c98cb979f-bbhxf 1/1 Running 0 5d23h cattle-system cattle-node-agent-dwnxk 1/1 Running 0 5d23h cattle-system kube-api-auth-d4zgq 1/1 Running 0 5d23h ingress-nginx default-http-backend-67cf578fc4-grmsw 1/1 Running 0 5d23h ingress-nginx nginx-ingress-controller-mpnmb 1/1 Running 0 5d23h kube-system canal-jw85q 2/2 Running 0 5d23h kube-system coredns-5c59fd465f-47q5z 1/1 Running 0 5d23h kube-system coredns-autoscaler-d765c8497-sm5xf 1/1 Running 0 5d23h kube-system metrics-server-64f6dffb84-bp864 1/1 Running 0 5d23h kube-system rke-coredns-addon-deploy-job-95qnk 0/1 Completed 0 5d23h kube-system rke-ingress-controller-deploy-job-brv7w 0/1 Completed 0 5d23h kube-system rke-metrics-addon-deploy-job-tvt89 0/1 Completed 0 5d23h kube-system rke-network-plugin-deploy-job-7rqcr 0/1 Completed 0 5d23h The same information (and much more) is available using rancher CLI.

Time to make checkpoint number 1 - it is day 11 of 30. So far - out of this 11 days I have 10 days with commits. The missing day was fully dedicated to working on presentation and documentation, that unfortunately ends up Confluence and Google Doc, not in some proper textual format (read: Markdown or RestructuredText) backed by a repository. Stuff that I worked on: some minor updates to resume (added AWS badges, fixed some typos) notes from certification courses + code fragments scripts for automation of documents / ebooks backup from iCloud to local drives Most commits went to documentation / practice code for my project “Many ways to Kubernetes” where I play with building up K8s clusters using different approaches.

This is the scariest thing I have read since spring 2018: https://hackernoon.com/im-harvesting-credit-card-numbers-and-passwords-from-your-site-here-s-how-9a8cb347c5b5 written by @david.gilbertson. It pretty sure what he describes is actually happening, has been happening before he described it and will be happening going on - just obviously not in the named module. The ecosystem of Node modules is so vast and so unstable that considerable number of project do not do enough to catch behaviour like this.

My work in last few years took my away from practical coding towards DevOps. Despite the increased role of IaaC in our DevOps, this often means living in iTerm and AWS console with interaction not being captured in any form. On writing side, lots of my output shifted from code towards writing text in Wiki’s, GoogleDocs and more and more in Slack messages. The code I write are short one-liners or small scripts with very short life span.
