DC/OS Vagrant Box

Vagrant box builder for use by tools such as miniDC/OS. It makes use of Packer to automate the build process.

The box produced by this builder does not include DC/OS, just its dependencies.

Pre-provisioning this box front-loads internet access requirements, flakiness, and slowness resulting from third party package managemers and installers. This makes DC/OS installation faster and more reliable at the cost of potentially having slightly outdated dependencies.

Provisioning Summary

Build

The DC/OS Vagrant Box is normally built in CI, on demand, but can be built manually as well.

Note that because the build process uses internet repositories with unversioned requirements, it's not exactly reproducible. Each built box may be slightly different than the last, but installations using the same box should be exactly the same.

Build Requirements

Build Pipeline

  1. Checkout - Clone or pull this repo
  2. Clean - Delete any left over box files
  3. Build - Use Packer to install the OS, runs all the build scripts, and export a compressed box file (~700MB)
  4. Upload - Upload the new box to S3
  5. Add - Add the new box version to the Vagrant Box Catalog Metadata (metadata.json)
  6. Publish - Upload the updated Vagrant Box Catalog Metadata to S3

Note that because the build process uses internet repositories with unversioned requirements, it's not exactly reproducible. Each built box may be slightly different than the last, but installations using the same box should be exactly the same.

Manual Build

Use the following commands to build a dcos-centos-virtualbox box:

cd <dcos-vagrant-box>
packer build -except=vmware-iso packer-template.json

Test

New boxes can be tested with either the Vagrantfile in this repo or (preferably) with miniDC/OS.

Test Requirements

Install Vagrant VBGuest Plugin

The VBGuest Plugin manages automatically installing VirtualBox Guest Additions appropriate to your local Vagrant version on each new VirtualBox VM as it is created.

vagrant plugin install vagrant-vbguest

This allows the pre-built vagrant box image to work on multiple (and future) versions of VirtualBox.

Test Local Box

To test a new local box (e.g. after ci/build_release.sh), add the box to vagrant and set the DCOS_BOX_VERSION environment variable:

cd <dcos-vagrant-box>
vagrant box add mesosphere/dcos-centos-virtualbox dcos-centos-virtualbox-iso.box
export DCOS_BOX_VERSION=0
vagrant up

Or with dcos-vagrant:

cd <dcos-vagrant>
vagrant box add mesosphere/dcos-centos-virtualbox dcos-centos-virtualbox-iso.box
export DCOS_BOX_VERSION=0
vagrant up [vms...]

To revert back to the remote Vagrant Box Catalog:

unset DCOS_BOX_VERSION
vagrant box remove mesosphere/dcos-centos-virtualbox --box-version=0

Test Local Catalog

To test a local Vagrant Box Catalog (e.g. after ci/update_catalog.sh), set the DCOS_BOX_URL environment variable:

cd <dcos-vagrant-box>
export DCOS_BOX_URL=file://~/workspace/dcos-vagrant-box/metadata.json
vagrant up

Or with dcos-vagrant:

cd <dcos-vagrant>
export DCOS_BOX_URL=file://~/workspace/dcos-vagrant-box/metadata.json
vagrant up [vms...]

To revert back to the remote Vagrant Box Catalog:

unset DCOS_BOX_URL
echo -n "https://downloads.dcos.io/dcos-vagrant/metadata.json" > ~/.vagrant.d/boxes/mesosphere-VAGRANTSLASH-dcos-centos-virtualbox/metadata_url
