vagrant files for Fedora and CentOS

Vagrant file and some scripts to start docker, k8s, nomad and consul on CentOS or Fedora. It is supporting only AWS and libvert now.

Note that k8s, nomad and consul are installed and started only on CentOS for now.

NOTE: vagrant-aws-mkubenka does not work with vagrant 2.2.19. If you use vagrant-libvirt on 2.2.19(or later?), do not install vagrant-aws-mkubenka.

install packages for vagrant

$ dnf install vagrant

or download vagrant CentOS RPM package from https://www.vagrantup.com/downloads.

install pcakges for aws plugin

$ dnf install ruby-devel libffi-devel redhat-rpm-config libvirt-devel

$ vagrant plugin install vagrant-aws

or(for spot instance support)

$ vagrant plugin uninstall vagrant-aws
$ vagrant plugin install vagrant-aws-mkubenka --plugin-version "0.7.2.pre.24"

Note: For spot instance, "Auto-assign public IPv4" for AWS VPC subnet needs to be set to yes.

install libvirt plugin(kvm/qemu)

$ dnf install vagrant-libvirt

$ vagrant plugin install vagrant-libvirt

disk resizing for VirtualBox

In order to resize disk spaze for VirtualBox provider, it needs following option to enable experimental feature of Vagrant.

export VAGRANT_EXPERIMENTAL="disks"

Example Vagrantfile:

   config.vm.provider "virtualbox" do |v, override|
     override.vm.box = LIBVIRTBOX
     override.vm.synced_folder ".", "/home/vagrant/sync", type: "rsync"
     # export VAGRANT_EXPERIMENTAL="disks" is necessary for following disk options
     override.vm.disk :disk, size: "50GB", primary: true

With these setup, Vagrant resize the primary disk device to 50GB. However it does not resize partitions of the device. It will need to run fdisk, partprobe and xfs_growfs commands(see example below).

Example:

[root@v2 ~]# fdisk /dev/sda

Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
