Renewing DHCP While Keeping a NetworkManager Connection Up

I recently changed my DNS setup on my home network and wanted to move all the clients over to the new nameserver before turning down the old one. My DHCP server was already updated to hand out the new DNS nameserver so all I needed to do was refresh the clients. Due to a few other changes in my network, I had a multi-hour file transfer going on between two machines.

Monitoring GitLab on Kubernetes

If you want decent monitoring of GitLab deployed via GitLab’s helm charts, skip the built-in Prometheus config and go straight to InfluxDB. Make sure you enable InfluxDB’s UDP interface and replace the autogenerated, default retention policy with a 1h policy. Use GitLab’s Grafana dashboards by using jq to extract the dashboard node from each .json file and then changing the datasource name to match yours.
