I'm looking for a way to pass parameter to Chef cookbook like:
$ vagrant up some_parameter
And then use some_parameter
inside one of the Chef cookbooks.
You cannot pass any parameter to vagrant. The only way is to use environment variables
MY_VAR='my value' vagrant up
And use ENV['MY_VAR']
in recipe.
You also can include the GetoptLong Ruby library that allows you to parse command line options.
Vagrantfile
require 'getoptlong'
opts = GetoptLong.new(
[ '--custom-option', GetoptLong::OPTIONAL_ARGUMENT ]
)
customParameter=''
opts.each do |opt, arg|
case opt
when '--custom-option'
customParameter=arg
end
end
Vagrant.configure("2") do |config|
...
config.vm.provision :shell do |s|
s.args = "#{customParameter}"
end
end
Then, you can run :
$ vagrant --custom-option=option up
$ vagrant --custom-option=option provision
Note: Make sure that the custom option is specified before the vagrant command to avoid an invalid option validation error.
More information about the library here.
It is possible to read variables from ARGV and then remove them from it before proceeding to configuration phase. It feels icky to modify ARGV but I couldn't find any other way for command-line options.
# Parse options
options = {}
options[:port_guest] = ARGV[1] || 8080
options[:port_host] = ARGV[2] || 8080
options[:port_guest] = Integer(options[:port_guest])
options[:port_host] = Integer(options[:port_host])
ARGV.delete_at(1)
ARGV.delete_at(1)
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
# Create a forwarded port mapping for web server
config.vm.network :forwarded_port, guest: options[:port_guest], host: options[:port_host]
# Run shell provisioner
config.vm.provision :shell, :path => "provision.sh", :args => "-g" + options[:port_guest].to_s + " -h" + options[:port_host].to_s
port_guest=8080
port_host=8080
while getopts ":g:h:" opt; do
case "$opt" in
g)
port_guest="$OPTARG" ;;
h)
port_host="$OPTARG" ;;
esac
done
@benjamin-gauthier 's GetoptLong solution is really neat, fits in with the ruby and vagrant paradigm well.
It however, needs one extra line to fix clean handling of the vagrant arguments, such as vagrant destroy -f
.
require 'getoptlong'
opts = GetoptLong.new(
[ '--custom-option', GetoptLong::OPTIONAL_ARGUMENT ]
)
customParameter=''
opts.ordering=(GetoptLong::REQUIRE_ORDER) ### this line.
opts.each do |opt, arg|
case opt
when '--custom-option'
customParameter=arg
end
end
which allows this block of code to pause when the custom options are processed.
so now,
vagrant --custom-option up --provision
or
vagrant destroy -f
are cleanly handled.
Hope this helps,
Vagrant.configure("2") do |config|
class Username
def to_s
print "Virtual machine needs you proxy user and password.\n"
print "Username: "
STDIN.gets.chomp
end
end
class Password
def to_s
begin
system 'stty -echo'
print "Password: "
pass = URI.escape(STDIN.gets.chomp)
ensure
system 'stty echo'
end
pass
end
end
config.vm.provision "shell", env: {"USERNAME" => Username.new, "PASSWORD" => Password.new}, inline: <<-SHELL
echo username: $USERNAME
echo password: $PASSWORD
SHELL
end
end
