This topic describes how to use Windows Server to deploy Roaming User Profiles to Windows client computers. Roaming User Profiles redirects user profiles to a file share so that users receive the same operating system and application settings on multiple computers.
There are multiple ways to run a Kubernetes cluster with Ubuntu. These pages explain how to deploy Kubernetes on Ubuntu on multiple public and private clouds, as well as bare metal.
Ignition is a new provisioning utility designed specifically for CoreOS Container Linux. At the the most basic level, it is a tool for manipulating disks during early boot. This includes partitioning disks, formatting partitions, writing files (regular files, systemd units, networkd units, etc.), and configuring users. On first boot, Ignition reads its configuration from a source-of-truth (remote URL, network metadata service, hypervisor bridge, etc.) and applies the configuration.
Even though Ignition only runs once, it packs a powerful punch. Because Ignition runs so early in the boot process (in the initramfs, to be exact), it is able to accomplish configuration all before the userspace has begun booting, which enables advanced features that Container Linux admins require.
VXLAN is an overlay network to encapsulate Ethernet traffic over an existing (highly available and scalable, possibly the Internet) IP network while accomodating a very large number of tenants. It is defined in RFC 7348. For an uncut introduction on its use with Linux, have a look at my “VXLAN & Linux” post.
VXLAN is an overlay network to carry Ethernet traffic over an existing (highly available and scalable) IP network while accommodating a very large number of tenants. It is defined in RFC 7348.
Starting from Linux 3.12, the VXLAN implementation is quite complete as both multicast and unicast are supported as well as IPv6 and IPv4. Let’s explore the various methods to configure it.
