Install Vagrant on Fedora
Run command on your terminal as below
dnf -y install vagrant
Test Vagrant and Virtualbox
Create a minimal Vagrantfile
$ mkdir vagrant-test
$ cd vagrant-test
$ vi Vagrantfile
An example that also sets the amount of memory and number of CPUs in the Vagrantfile file
[huupv@localhost vagrant-test]$ cat Vagrantfile
Vagrant.configure("2") do |config|
config.ssh.insert_key = false
config.vm.provider :virtualbox do |vb|
vb.memory = 256
vb.cpus = 1
end
config.vm.define "DevopsRoles" do |server01|
server01.vm.hostname = "DevopsRoles.com"
server01.vm.box = "centos/7"
#server01.vm.network :private_network, ip: "192.168.3.4"
end
end
