Modern scale-out environments with containers make log collection difficult. We present concepts and methods for collecting application logfiles with a sidecar container in Kubernetes environments.
Some application developers try to handle containerized applications as if they were conventional monoliths, but managing updates and security patches in containers needs a totally different approach.
Kubernetes has limited support for multitenancy, so many admins prefer to build multiple standalone Kubernetes clusters that eat up resources and complicate management. As a solution, Loft launches any number of clusters within the same control plane.
Automatically update software in the Docker universe with Watchtower.
Enforce container compliance in Kubernetes in one of two ways: with Open Policy Agent or Gatekeeper.
A zero-ops installation of Kubernetes with MicroK8s operates on almost no compute capacity and roughly 700MB of RAM.
Create a full-blown Kubernetes cluster in a Docker container with just one command.
Tune the iptables configuration for Docker by establishing your own forwarding rules.
Traefik promises not only to manage mesh implementations for container environments reliably, but to do so in a way that makes them enjoyable to administer.
Software from the open source OpenEBS project provides a cloud-native storage environment that makes block devices available to individual nodes in the Kubernetes cluster.
