The following works: # From my shell on macOS: I already have a private repo on the free Dockerhub which I am able to push/pull after I login. In the next article, we will take a look at how to ansible provisioner to automate our workflow using playbooks.I would like to create a provisioner that can pull a docker image from a private repository. config.vm.provision "file", source: "/home/karthick/vagrant/centos7", destination: "~/centos7" If you want the same name for your directory as in the source you have to provide the destination name same. To copy a directory you have to pass the directory path in source and destination. If you start/restart the virtual machine you will see in the log file provisioner is called and the file is copied to the virtual machine. config.vm.provision "file", source: "/home/karthick/vagrant/centos7/script.sh", destination: "~/script.sh" Replace source and destination path according to your location. To copy a file add the following property in your Vagrantfile with source and destination path. File provisioner accepts two parameter source paths and destination paths. Run External Script in Vagrant How to Use File Provisioner in Vagrantįile provisioner lets you upload files are directories to the vagrant machine from your host machine. The vagrant will copy the script to /tmp/ location in the virtual machine and will trigger the script. config.vm.provision "shell", path: "/home/karthick/welcome.sh" This is pretty simple, create a shell script externally and provide the path of the script in the shell provisioner as below. How to Work with External Script in VagrantĪn alternate option to the inline script is the external script. You can also pass -no-provision flag with the start/reboot command to suppress the run parameter behavior. nfigure("2") do |config|Ĭonfig.vm.provision "shell", inline: "/usr/bin/bash ~/welcome.sh", When set to “ never” the provisioner will not run. Run accepts two values “ always” and “ never”. If you want the provisioner to run whenever you start/reboot your virtual machine then you can use block style definition and pass “ always” to “ run”. Inline: "/usr/bin/bash /home/vagrant/welcome.sh" I have a test script named welcome.sh in vagrant host and to run it add the following syntax to the configuration file. You can also call the scripts that are already available in the vagrant machine. You can see from the above screenshot both epel-repo and wget are installed successfully. Install Epel Repository in VM Install Wget in VM I am passing the $COMMANDS variable as the value to inline which will run the series of yum commands we passed inside the block of code. I am creating a variable called $COMMANDS and storing heredoc in the variable. $COMMANDS = <<-'BLOCK'Ĭonfig.vm.provision "shell", inline: $COMMANDS Here I am trying to install epel-repository and install the wget command. Similar to that Ruby also supports Heredoc which you can use in vagrant files and redirect a series of bash commands to it. If you have worked with bash you might have used heredoc. config.vm.provision "shell" do |cmd|Ĭmd.inline = "echo Welcome to Linuxshelltips" This is the same as the previous one-line definition. You can also use block syntax which offers more readability. $ vagrant reload -provision # Restarting the VM Shell Provisioner $ vagrant up -provision # Starting the VM Take a look at the below image, I added the shell provisioner to the Vagrantfile and started my virtual machine and it tells me to use the -provision flag since this is not the first time I am booting this VM. Provisioner normally runs only when you execute “ vagrant up” for the first time. config.vm.provision "shell", inline: "echo Welcome to linuxshelltips"īefore running any provisioner there is an important point to be noted. Go ahead and modify the Vagrantfile and add the above line. After defining the shell provisioner you have to pass inline and command as a key-value pair. The below example shows how to use an inline script. There are many ways to use an inline script. In the inline script, you will pass the shell commands inside the Vagrantfile. How to Work with Inline Script in Vagrant There are two ways you can execute shell commands in vagrant. To use shell provisioner you have to pass shell as the argument to vm.provision method. Shell provisioners allow you to execute shell commands in your vagrant machine. How to Use a Shell Provisioner in Vagrant This article will see two of the provisioner’s File and Shell that you may use regularly when you are deploying new virtual machines. You can use any of these tools and automate your virtual machine deployment workflow. Vagrant support provisioners like file, shell, ansible, puppet, and salt stack. Provisioners are tools that allow you to automate your workflow when you are booting up a virtual machine.
