DTaaS Vagrant Box

This README provides instructions on creating a custom Operating System virtual disk for running the DTaaS software. The virtual disk is managed by vagrant. The purpose is two fold:

  • Provide cross-platform installation of the DTaaS application. Any operating system supporting use of vagrant software utility can support installation of the DTaaS software.
  • Create a ready to use development environment for code contributors.

There are two scripts in this directory:

Script name Purpose Default
user.sh user installation ✅
developer.sh developer installation ❌

If you are installing the DTaaS for developers, the default installation caters to your needs. You can skip the next step and continue with the creation of vagrant box.

If you are a developer and would like additional software installed, you need to modify Vagrantfile. The existing Vagrantfile has two lines:

1
2
    config.vm.provision "shell", path: "user.sh"
    #config.vm.provision "shell", path: "developer.sh"

Uncomment the second line to have more software components installed. If you are not a developer, no changes are required to the Vagrantfile.

This vagrant box installed for users will have the following items:

  1. docker v24.0
  2. nodejs v18.8
  3. yarn v1.22
  4. npm v10.2
  5. containers - ml-workspace v0.13, traefik v2.10, gitlab-ce v16.4, influxdb v2.7, grafana v10.1, rabbitmq v3-management, eclipse-mosquitto (mqtt) v2

This vagrant box installed for developers will have the following items additional items:

  • docker-compose v2.20
  • microk8s v1.27
  • jupyterlab
  • mkdocs
  • container - telegraf v1.28

At the end of installation, the software stack created in vagrant box can be visualised as shown in the following figure.

vagrant base box

The upcoming instructions will help with the creation of base vagrant box.
