The following tutorial will walk you through downloading the official CoreOS VMware images and configuring them using a cloud config drive. Once configured, the VMware images will be launched under VMware Fusion, and we will utilize the vmrun cli tool to interact with it.

Download VMware Images

wget http://alpha.release.core-os.net/amd64-usr/current/coreos_production_vmware.vmx
wget http://alpha.release.core-os.net/amd64-usr/current/coreos_production_vmware_image.vmdk.bz2

Decompress the disk image:

bzip2 -d coreos_production_vmware_image.vmdk.bz2

Generate cloud configs

Many of the vmrun guest OS commands require a valid username and password in order to work, some command require root access.

Generate the password hash for the core user

openssl passwd -1
Password:
Verifying - Password:
$1$83p0.W1P$rx1Gw1llFuNKfwWtcceA7/

Generate the password hash for the root user

openssl passwd -1
Password:
Verifying - Password:
$1$AwvTHbE9$RUB6nEX8dW5BJFbVDb207/

Create a cloud config file

A cloud config file can be used to bootstrap a CoreOS host. In our example we will create two user, core and root using the password generated above

edit cloud-config.yaml

#cloud-config

users:
  - name: core
    passwd: $1$83p0.W1P$rx1Gw1llFuNKfwWtcceA7/
    groups:
      - sudo
      - docker
  - name: root
    passwd: $1$AwvTHbE9$RUB6nEX8dW5BJFbVDb207/

Create a config drive

Generate a cloud config drive ISO

mkdir -p /tmp/new-drive/openstack/latest
cp cloud-config.yaml /tmp/new-drive/openstack/latest/user_data
hdiutil makehybrid -iso -joliet -joliet-volume-name "config-2" -o ~/cloudconfig.iso /tmp/new-drive
rm -r /tmp/new-drive

Add the cloud config drive to the VM

Append the following lines to coreos_production_vmware.vmx

ide0:0.present = "TRUE"
ide0:0.autodetect = "TRUE"
ide0:0.deviceType = "cdrom-image"
ide0:0.fileName = "/Users/kelseyhightower/cloudconfig.iso"
