Ironman: Open Source Containers and Virtualization in bare metal
| Resumo: | Computer virtualization has become prevalent throughout the years for both business and personal use. It allows for hosting new machines, on computational resources that are left unused, running as independent computers. Apart from the traditional virtual machines, a more recent form of virtualization was introduced and will be explored in this project, containers, more specifically Linux Containers. While multiple virtualization tools are available, some of them require a premium payment, while others do not support container virtualization. For this project, LXD, an open source virtual instance manager, will be used to manage both virtual machines and containers. For added service availability, clustering support will also be developed. Clustering will enable multiple physical computers to host virtual instances as if they were a single machine. Coupled with the Ceph storage back end it allows for data to be replicated across all computers in the same cluster, enabling instance recovery when a computer from the cluster is faulty. The infrastructure deployment tool Puppet will be used to automate the installation and configuration of an LXD virtualization system for both a clustered and non clustered environment. This allows for simple and automatic physical host configuration limiting the required user input and thus decreasing the possibilities of system misconfiguration. LXD was tested for both environments and ultimately considered an effective virtualization tool, which when configured accordingly can be productized for a production environment. |
