How can avoid the echo command run each time as I run "vagrant up --provision"

[Jason Yu]

I have the following vagrantfile. If I run it for the  first time with "vagrant up", it works well. but when I ran it for the second time with "vagrant up --provision" it added the "export P4CONFIG=/vagrant/repos/.p4config"

it adds this line every time I run the command. Is there a way I can avoid it to be added twice?

Vagrant.configure("2") do |config|

## Specify the base box

config.vm.box = "xxxxx/vagrant_developer_box"

config.vm.box_version = "0.07"

## source .p4config file in .bashrc

config.vm.provision "shell", inline: 'echo "export P4CONFIG=/vagrant/repos/.p4config" >> /home/vagrant/.bashrc'

config.vm.provision "shell", inline: 'echo "After you ssh in, please modify the P4USER and P4PASSWD in your .p4config file" >> /etc/motd'

## Mount the user repos dir

config.vm.synced_folder '.', '/vagrant/repos', id: "vagrant-root",

owner: "vagrant",

group: "vagrant",

mount_options: ["dmode=775,fmode=664"]

config.vm.box_download_insecure = true

Hey there,

Provisioners have the option to define how often you want them to run. You can add a new key that will make it run only once:

config.vm.provision "shell", run: "once", inline: "echo 'hi'"

More information can be found here https://www.vagrantup.com/docs/provisioning/basic_usage.html#run-once-always-or-never

Thanks!

hello.

make your scripts idempotent.

just add those lines if you need them

ie

config.vm.provision "shell", inline: 'grep P4CONFIG /home/vagrant/.bashrc || echo "export P4CONFIG=/vagrant/repos/.p4config" >> /home/vagrant/.bashrc'

Thanks

Alvaro
