Because each existing Packer template is quite unique, I cannot simply provide a definite guide here. Hence, I suggest you instead look for templates made by others, and customize them, if necessary.
If in doubt, deliberately use older hypervisor versions on the build machine.Ĭreate a Vagrant box with Packer, using pre-made templatesĬreating your own Packer templates from scratch is a lot of work. I’ve personally encountered this problem, where a box built with VirtualBox 6.x would not start on a different host that has VirtualBox 5 installed. In particular, some hypervisors are not downward compatible, i.e., if you create a VM (and the resulting box) on a newer version of the hypervisor on host #1, it might not start using an older hypervisor version on host #2.
Tips and caveatsīefore I present some details regarding specific operating systems, there are a few general points to consider before you start using Packer templates:īeware of version incompatibilities of hypervisors. To find well-maintained templates at the time you read this, I suggest you just search the Internet for terms like “packer template ”, e.g. However, these templates come and go over time. The remainder of this article will contain links to a few of those. Thus, I recommend you use pre-made templates. It is possible to build such templates yourself, but it requires a lot of skill and expertise. The recipe that tells Packer how to do these things is called a packer template. These steps run fully automated, and can be repeated for different providers, like Hyper-V or VirtualBox.
Installs custom software packages that you define,.Configures settings in the OS, such as creating a vagrant user,.Installs OS updates, downloading them from the Internet,.Installs the OS into the new VM, from the installation medium,.Downloads an installation medium (e.g.
Hashicorp’s Packer is a separate tool which create boxes. This reduces the provisioning time for a new VM, because that software already comes with the box, thus it does not need to be provisioned. You need a customized box where specific software is already pre-installed.
