Re: [vagrant-up] Re: Using array variables in Vagrantfile?
I got some help and the following can be done if used directly in the
vagrantfile
"10.10.10.11 10.10.10.12".scan(/\S+/)
although I am unable to substitute the variable that I export. If before
running vagrant up I export the variable
export LIST_OF_IP="10.10.10.11 10.10.10.12"
and the vagrantfile has the following:
CFG_IP = ENV['LIST_OF_IP'].scan(/\S+/)
It throws an error:
Message: NoMethodError: undefined method `scan' for nil:NilClass. Any
ideas on how the variable can be substituted
CFG_IP = ENV['LIST_OF_IP'].scan(/\S+/) ==> have also tried
"$LIST_OF_IP".scan(/\S+/)
CFG_NAME="test-vm-"
#TODO: Configure private networks and assign static ip
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.ssh.forward_agent = true
#(1..CFG_NUM).each do |i|
CFG_IP.to_enum.with_index(1).each do |ip, i|
config.vm.define CFG_NAME+"#{i}" do |s|
s.vm.box = "ceph/ubuntu-xenial"
s.vm.hostname = CFG_NAME+"#{i}"
s.vm.network :private_network, ip: ip
s.vm.provider :libvirt do |v|
v.memory = 4094
v.cpus = 2
v.nested = true
end
end
end
end

So I now want to export a variable with space separated IPs
ARR_IP="10.20.20.10 10.20.20.11 10.20.20.12"
Is there a way to break this up in the Vagrantfile? Some sort of
operations?

Re: [vagrant-up] Re: Using array variables in Vagrantfile?
I tried to do the following:
CFG_IP="$LIST_IPS".split(",") or CFG_IP="$LIST_IPS".split(" ")
Neither worked and added a debug to understand
DEBUG create_networks: In config found network type private_network options
{:ip=>"$LIST_IPS", :protocol=>"tcp",
:id=>"49129a87-dcdd-4539-a898-e2ef8b2bed38"}
Dont think the substitution worked as I had expected.

Re: [vagrant-up] Re: Using array variables in Vagrantfile?
Thank you Alvaro. This certainly helps but since I am exporting a space
separated(or comma separated) variable of IP addresses can I perform
operations on the env var in the vagrantfile for it to become a list that u
mentioned
export LIST_IP="10.10.10.10 10.10.10.11"
in Vagrantfile:
CFG_IP=$LIST_IP (some action on LIST_IP)
How can I perform some operation on the var LIST_IP in the vagrant file so
that CFG_IP becomes ["10.10.10.10", "10.10.10.11"] so that its usable like
the way you defined.

Re: [vagrant-up] Re: Using array variables in Vagrantfile?
you can use:
["192.168.11.11", "192.168.12.12"].to_enum.with_index(1).each do |ip, i|
then you can use the ip and/or the index/counter i
