Bhojpur Host - Infrastructure Framework

The Bhojpur Host is a high-performance, compute hosting resource provider applied within the Bhojpur.NET Platform ecosystem for delivery of distributed applications or services. It lets you create virtual or Container hosts and/or Unikernel hosts on a bare metal computer, on cloud providers (e.g., Amazon Web Services, Google Cloud Platform, Microsoft Azure, DigitalOcean, IBM Bluemix, Oracle Cloud Infrastructre), and inside your own data center (e.g. using OpenStack, VMware). It creates servers, installs the Bhojpur Host server-side runtime engine on them, then configures the Bhojpur Host client-side CLI to talk to them.

The Bhojpur Host project is intended to be embedded and executed by full Bhojpur products. The standalone Bhojpur Host CLI functionality will remain, but human use of it will not be our primary focus as we would expect inputs provided by other things (e.g., Terraform or User Inferfaces)

Key Features

• Computing Host instance management
• Host Farm (i.e. cluster) management
• Container Cluster Operations management

It integrates seamlessly with the Bhojpur DCP (i.e., distributed cloud platform), which leverages Bhojpur OS as its operating system and the Bhojpur Kernel framework for Unikernel development.

Computing Host Instance Provision

The Bhojpur Host machine instance is managed using hostutl tool. It can provision hosting nodes (i.e. machine instances) in a Virtualized Data Center. It could connect to a wide range of Cloud infrastructure providers.

To get a list of hosting machines available in the resource pool, type the following command

$ hostutl ls

To create a new machine instance locally using virtualbox driver

$ hostutl create --driver virtualbox default

To remove a host machine from managed resource pool

$ hostutl rm default

Host Farm Cluster Provision

The Bhojpur Host server farm is managed using the hostfarm tool. It creates Kubernetes clusters on different Cloud infrastructure providers.

A list of commands to manage Kubernetes Cluster in a multi-cloud environment

$ hostfarm create --driver $driverName [OPTIONS] cluster-name
$ hostfarm inspect cluster-name
$ hostfarm ls
$ hostfarm update [OPTIONS] cluster-name
$ hostfarm rm cluster-name

To see what driver create options it has, run the following command

$ hostfarm `create --driver` $driverName --help

To see what update options for a cluster, run the following command

$ hostfarm update --help cluster-name

A serviceAccountToken that binds to the clusterAdmin is automatically created for you, to see what it is, run the following command

$ hostfarm inspect clusterName

Before running Google Kubernetes Engine driver, make sure you have the credential. To get the credential, you can run any of the steps below

gcloud auth login or,

export GOOGLE_APPLICATION_CREDENTIALS=$HOME/gce-credentials.json or,

$ hostfarm create --driver gke --gke-credential-path /path/to/credential cluster-name

Container Cluster Operations Management

The Bhojpur Kubernetes Engine could host a wide range of applications or services. It is managed using the hostops tool. The installation and configuration of hosting clusters is the primary focus of hostops tool.

$ hostops

Build Source Code

Firstly, you need a running instance of Docker instance so that the dapper tool can build everything from the source code and use a local Docker Registry.

$ sudo make

Alternately, you can use the following commands

$ task build-tools
$ task build-cloud
