The latest Vagrant box of OEL8 will be downloaded, and Vagrant can tell us which Vagrant boxes are downloaded so far. Now we are good to go, so start the virtual machines with Vagrant. # create a linked clone of the master VM config.vm.define "email-MDA" do |mda| mda.vm.box_check_update = false mda.vm.box = "ol8-latest" mda.vm.box_url = " " mda.vm.define "ol8-smtp-mda" # name of the virtual machine instance mda.vm.hostname = "" # assign a static IP mda.vm.network "private_network", ip: "192.168.1.10" end Now configure the second virtual machine. # create a linked clone of the master VM config.vm.define "email-MTA" do |mta| mta.vm.box_check_update = false mta.vm.box = "ol8-latest" mta.vm.box_url = " " mta.vm.define "ol8-smtp-mta" # name of the virtual machine instance mta.vm.hostname = "" # assign a static IP mta.vm.network "private_network", ip: "192.168.1.9" end We’ll assign a host name and static IP address.
Now let’s configure the attributes of the first virtual machine. For the linked clones only differencing disk images are created where the parent disk image belongs to the master VM. Linked clones are based on a master VM, which is generated by importing the base box only once the first time it is required. Using linked clones can drastically reduce this overhead. For large boxes this produces a large overhead in terms of time (the import operation) and space (the new machine contains a copy of the base box’s image). # create a master VM before creating the linked clones vb.linked_clone = trueįrom the Vagrant documentation, the ‘linked_clone = true’ does the following:īy default new machines are created by importing the base box.
VAGRANT LAWS CODE
# hardware bound config.vm.provider "virtualbox" do |vb| vb.memory = 1024 vb.cpus = 1 # create a master VM before creating the linked clones vb.linked_clone = true endĪt the end of the first code block I have configure the ‘linked_clone = true’. Let’s start with each virtual machine receiving a maximum of 1GB of memory, and just 1 CPU core. endįor the first code block, you may want to create a resource limit for each virtual machine. nfigure(VAGRANTFILE_API_VERSION) do |config|. So all the code blocks will be placed within the main block. However, to get multi-machines, the Vagrant file needs to be edited. Out-of-the-box, the Vagrant file present in the \OracleLinux\8 directory will configure a single virtual host using the latest OEL8.
