Current Trends in DC Networking - CoreOS Install


As I outlined in my last post, CoreOS Container Linux is not your traditional operating system. The same can be said about the base install of CoreOS.

Depending on the use case there are multiple deployment options for CoreOS. For cloud deployments all major providers are supported.



For bare metal installs you can either iPXE/PXE install to memory or install to disk. Also with VMWare you have the option to install through an OVA. and point to your cloud-config or ignition file via a config drive.

Even though I am running this lab on VMWare vSphere Im going to use the bare metal install.

Current Trends in DC Networking - CoreOS

Now that the network side of this series is complete we can move onto the servers. Containers and micro-services are all the rage these days and continuing to grow in popularity. When virtualization took over the data center we saw a shift in many aspects of data center server and application management. We even started to see a shift in how networks were designed and networking logic started shift into the servers.

Now with the rise of containers upon us, we are seeing a lot of the same things happening as applications and services start to move into containers. And the shift of network control is continuing to move further into the servers.



Operating systems have all embraced the support for containers, including Windows now. CoreOS has emerged with a unique approach as a container focused server OS with Container Linux (formerly just CoreOS) and has built a solid reputation against the giants in the server world.

So lets dig into CoreOS as see what we can do with it!
