Simple Vagrant setup to quickly create multiple VM`s for testing and developing Epiphany clusters locally.
- Ubuntu with libvirt
- Latest Vagrant
- Vagrant libvirt provider
Other Linux distros should work but are untested.
- MacOS with libvirt
- Latest Vagrant
- Vagrant libvirt provider
MacOS should work but is untested.
There are 2 ways of configuration.
1: you can quickly create a number of similar VM`s with only the basic config:
cfg = {
:provider => "hyperv", # Set the which vagrant provider we want to use. "hyperv" on Windows and "libvirt" on Linux and MacOS.
:group => "group1", # Group included in a VM name.
:vm_count => 4, # If set to 0 a set of VM`s will be created with the definitions in boxes below. Of > 0 then the general cfg (vm_cpus, vm_memory) is used.
:vm_prefix => "prefix", # Prefix that will be used for creating the clusters.
:vm_cpus => 2, # Number of CPU cores each VM should have when using the vm_count.
:vm_memory => 2048, # Amount of memory each VM should have when using the vm_count.
:vm_box => "generic/ubuntu1804", #"generic/rhel7", "centos/7", # Image to use for the VM`s.
:ssh_priv => "/path/to/ssh/private/key", # Path of the private SSH key that you want to use to connect to the VMs
:ssh_public => "/path/to/ssh/public/key", # Path of the public SSH key that you want to use to connect to the VMs
:network_switch => "switchname" # HYPER-V ONLY - The network switch you want to use to connect the VMs to. This must be created in Hyper-V manager before hand and needs to be an external switch.
}With the above configuration 4 VM`s will be created labeled prefix1 ... ```prefix4``` with the specifications defined in ```vm_cpus``` and ```vm_memory```. The hostnames will be the same is the created VM labels.
2: You can set the vm_count to 0 and define a number of custom VM`s based on the configuration in the boxes array:
boxes = [
{
:name => "Kubernetes Master", # Name of the machine.
:hostname => "kmaster", # Hostname this VM will get on the network.
:memory => 2048, # Ammount of memory this VM will have.
:cpus => 2 # Number of CPU cores this VM will have.
},
{
:name => "Kubernetes Node 1", # Name of the machine.
:hostname => "knode1", # Hostname this VM will get on the network.
:memory => 2048, # Ammount of memory this VM will have.
:cpus => 2 # Number of CPU cores this VM will have.
},
{
:name => "Kubernetes Node 2", # Name of the machine.
:hostname => "knode2", # Hostname this VM will get on the network.
:memory => 2048, # Ammount of memory this VM will have.
:cpus => 2 # Number of CPU cores this VM will have.
}
]This will create 3 VM`s with the defined settings.
The following settings of the basic config will be used for both approaches described above:
cfg = {
:provider => "hyperv" # Set the which vagrant provider we want to use. "hyperv" on Windows and "libvirt" on Linux and MacOS.
:group => "group1", # Group included in a VM name.
:vm_box => "generic/ubuntu1804", #"generic/rhel7", "centos/7", # Image to use for the VM`s.
:ssh_priv => "/path/to/ssh/private/key", # Path of the private SSH key that you want to use to connect to the VMs.
:ssh_public => "/path/to/ssh/public/key", # Path of the public SSH key that you want to use to connect to the VMs.
:network_switch => "switchname" # HYPER-V ONLY. The network switch you want to use to connect the VMs to. This must be created in Hyper-V manager before hand and needs to be an external switch.
}You can use the normal Vagrant commands to manage the VM`s you create for the cluster. Few of the most common:
vagrant up ...to create a new set of VM`svagrant destroy ...to destroy a set of VM`svagrant snapshot ...for creating and managing VM snapshots. Usefull when developing functionality that needs to be retested frequently.
