Start your servers. You signed in with another tab or window. Reload to refresh your session. You signed out in another tab or window.So far I have used the install kernel, the install init ram disk and the fedora-core-os bare metal image to install on VMware.
My question is if this approach is at all possible. I really hope it is at it will save me the work to set-up a bare metal server in the data centre.
So far the first phase of the installation seems to work fine. When the server reboots the system goes into the emergency. What you are trying to accomplish should indeed be feasible. The root issue is likely related to the content of your Ignition configuration, or how you are passing it via the installer.
Before digging further into this, please note that we directly provide OVA images.
Thanks for the answer. I slimmed down my ignition file to the bare minimum a user and a method to be able to login and indeed now it works! The transpiler did not complain so it was at least not a silly formatting error. Probably some logical error on my behalf. Out of curiosity, do you intend to expand on the FCOS configuration options?
In CoreOS one could configure network options in the ignition file too. Is that in the pipeline for fedora coreOS? There is an ignition-validate binary attached to each Ignition release that you can use to validate the syntax of your Ignition config.
Hi, I hope I am right here to ask the following question. Regards, Johan. Hi, Thanks for the answer.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This repo provides a template Vagrantfile to create a CoreOS virtual machine using the VirtualBox software hypervisor.
After setup is complete you will have a single CoreOS virtual machine running on your local machine. Mailing list: coreos-dev. There are two "providers" for Vagrant with slightly different instructions.
Follow one of the following two options:. The VMware provider is a commercial addon from Hashicorp that offers better stability and speed.
If you use this provider follow these instructions. Configuration is stored in the directory so you can always return to this machine by executing vagrant ssh from the directory where the Vagrantfile was located.
There is optional shared folder setup.
How to install and configure CoreOS inside VMware
You can try it out by adding a section to your Vagrantfile like this. When using the VirtualBox provider for Vagrant the defaultIgnition is used to provision the machine. This uses a special plugin that is automatically installed when using the default Vagrantfile. The config options for the plugin are all prefixed with config. More configuration may be added if necessary. Then, use config transpiler to write the Ignition config to config.
There is also a basic Ignition file provided based on the Container Linux config that is included. To use that instead not recommendedcopy config. Check out the Ignition Getting Started documentation to learn about the available features. To get started, copy user-data. Check out the coreos-cloudinit documentation to learn about the available features. The Vagrantfile will parse a config. See config. If using the VirtualBox provider defaultcopy the make sure to create a config.
Also, make sure to provide a fresh discovery URL in your config. If you are using the VMWare provider, make sure you provide a fresh discovery URL in your user-data if you wish to bootstrap etcd in your cluster.
CoreOS is a rolling release distribution and versions that are out of date will automatically update. If you want to start from the most up to date version you will need to make sure that you have the latest box file of CoreOS.
You can do this by running. The first machine will be available on the port that you specify and each additional machine will increment the port by 1. If vagrant fails to run successfully, first make sure that the latest version of the coreos-vagrant project has been downloaded, then run vagrant destroy -f to remove old machines, vagrant box update to update the OS box, and vagrant plugin update vagrant-ignition to update the ignition plugin.

Minimal Vagrantfile for Container Linux. Branch: master.September 27, 2 Comments. Fortunately for me and you! Information about the supported properties is here. The short version is that you base64 encode and inject your cloud-config, along with any additional parameters.
For me it looks like:. Ok, so this is all great, but how to you get it into VMWare? You have two choices, you can manually edit the. VMX file boring! The script I use is in githubbut the workflow is basically:.
The script will pick up a cloud-config. Check out the source in github to learn more. For example, guestinfo. Filed under Linux.
Too many interests to list here, check out my posts, or look me up on LinkedIn. Great article Robert! My system is esx 5. Are there any special settings that need to be in place on the vmware side for that to work? The api created the machines just fine, and the vmx file has the correct information in it. Kind of stumped at the moment. Sorry for the long delay. Make sure the interface name is actually ens … depending on the VNIC you chose or the ESX version, the kernel might give it some other name.

I simply wanted to automate the process and have a means of showing a working cluster, hence this blog post. For the etcd VM, this only happens once and requires not cognizance of any other machines.
Enter that directory. This is where all the generated files and VMware images will exist. You will need to find the utility vmlist. When this utility is run, it will need to be run via sudoor you can change it to allow the user you use to have the execute privilege to it. After this script is completed, there should be the image in the expected location. Log into the instance. Now the cluster can be launched.
As the above example shows, the IP address for etcd is This will be the single argument to the next script:. This will result in the same sequence of steps as the etcd server, but 3 times. Once all VMs are launched, you can verify that they are up:. A working cluster! Next, create a test service and launch it. In this example, the "hello" service shown on Core OS Quickstart.
Once the service is created as a file with the editor of choice, submit it and run it. This document has shown how to easily set up a CoreOS cluster, as well as how to do some useful work with the VMware command line tools.
Lastly, many many thanks to Kelsey Hightower for his patience and help with setting this up and answering a slew of questions! Skip to content.

If you do not have one, see Producing an Ignition File. Fedora CoreOS is designed to be updated automatically, with different schedules per stream. Once you have picked the relevant stream, you can download the latest OVA:.
Alternatively, OVA images can be manually downloaded from the download page. For the vmware provider, Ignition requires two "guestinfo" fields to be present when the VM is first booted:. For maximum compatibility, it is recommended to use base64 encoding and to prepare the Ignition configuration as such:. This section shows how to use vSphere facilities to configure and run VMs, via the govc utility.State of containers: a debate with CoreOS, VMware and Google

As an operating system, Container Linux provides only the minimal functionality required for deploying applications inside software containerstogether with built-in mechanisms for service discovery and configuration sharing. Container Linux adds new functionality and customization to this shared foundation to support server hardware and use cases. Container Linux provides no package manager as a way for distributing payload applications, requiring instead all applications to run inside their containers.
Serving as a single control host, a Container Linux instance uses the underlying operating-system-level virtualization features of the Linux kernel to create and configure multiple containers that perform as isolated Linux systems. That way, resource partitioning between containers is performed through multiple isolated userspace instances, instead of using a hypervisor and providing full-fledged virtual machines.
Initially, Container Linux exclusively used Docker as a component providing an additional layer of abstraction and interface  to the operating-system-level virtualization features of the Linux kernel, as well as providing a standardized format for containers that allows applications to run in different environments. Container Linux uses ebuild scripts from Gentoo Linux for automated compilation of its system components,   and uses systemd as its primary init system with tight integration between systemd and various Container Linux's internal mechanisms.
Container Linux achieves additional security and reliability of its operating system updates by employing FastPatch as a dual-partition scheme for the read-only part of its installation, meaning that the updates are performed as a whole and installed onto a passive secondary boot partition that becomes active upon a reboot or kexec.
This approach avoids possible issues arising from updating only certain parts of the operating system, ensures easy rollbacks to a known-to-be-stable version of the operating system, and allows each boot partition to be signed for additional security. To ensure that only a certain part of the cluster reboots at once when the operating system updates are applied, preserving that way the resources required for running deployed applications, CoreOS provides locksmith as a reboot manager for Container Linux.
Internally, locksmith operates as the locksmithd daemon that runs on cluster members, while the locksmithctl command-line utility manages configuration parameters. The updates distribution system employed by Container Linux is based on Google 's open-source Omaha project, which provides a mechanism for rolling out updates and the underlying request—response protocol based on XML.
Operations available through CoreUpdate include assigning cluster members to different groups that share customized update policies, reviewing cluster-wide breakdowns of Container Linux versions, stopping and restarting updates, and reviewing recorded update logs. Container Linux provides etcd, a daemon that runs across all computers in a cluster and provides a dynamic configuration registry, allowing various configuration data to be easily and reliably shared between the cluster members.
Etcd is also used in Kubernetes software. Container Linux also provides the fleet cluster manager which controls Container Linux's separate systemd instances at the cluster level. As of "fleet" is no longer actively developed and is deprecated in favor of Kubernetes. Using fleetd allows the deployment of single or multiple containers cluster-wide, with more advanced options including redundancyfailoverdeployment to specific cluster members, dependencies between containers, and grouped deployment of containers.
A command-line utility called fleetctl is used to configure and monitor this distributed init system;  internally, it communicates with the fleetd daemon using a JSON-based API on top of HTTP, which may also be used directly.
When used locally on a cluster member, fleetctl communicates with the local fleetd instance over a Unix domain socket ; when used from an external host, SSH tunneling is used with authentication provided through public SSH keys.
All of the above-mentioned daemons and command-line utilities etcdetcdctlfleetd and fleetctl are written in the Go language and distributed under the terms of the Apache License 2. Container Linux can also be deployed through its commercial distribution called Tectonicwhich additionally integrates Google's Kubernetes as a cluster management utility. Following its acquisition of CoreOS, Inc. For those who are putting together large, distributed systems—web applications being a prime example—CoreOS would appear to have a lot of interesting functionality.
It should allow applications of that type to grow and shrink as needed with demand, as well as provide a stable platform where upgrades are not a constant headache. For "massive server deployments", CoreOS, or something with many of the same characteristics, looks like the future.
