Why Bare Metal Provisioning?

 

Automation and consistency across Linux infrastructure is hard. Our goal is to make Linux installations of heterogeneous hardware across 10s to 1000s of machines fast, flexible, and absolutely consistent.

The Stacki default installation process will bring bare metal infrastructure (or VMs) to a ping and a prompt. The frontend machine has password-less SSH access to the backend machines on first boot, and the repositories on the frontend act as YUM repositories for all backend machines. All machines will be at the latest kernel and RPM revisions of the OS and installed applications.

Stacki initial installations are relatively fast and simple, but may not completely reflect site-specific desired state. Configuration can be layered on using advanced features to customize local environments. The speed of installation/reinstallation Stacki provides allows convergence to a known/desired configuration of resources that reflect local needs. Deployed across the infrastructure, you’ve just made the complex simple and repeatable for existing or new infrastructure.

What is Stacki ?

Stacki is a CentOS/RHEL bare metal install tool that can take your servers from bare hardware (or virtual hardware) to working Linux, ready to install applications. Stacki does this at scale, so deploying 1000+ servers is no more complex than deploying one. Advanced users can use Stacki to install applications (Hadoop, OpenStack, HPC etc.). Stacki has a long history, and is in use at some of the most demanding organizations in the world.

 

What does Stacki do?

  • Configure RAID controllers and partitioning (both customizable).
    (This means you never have to touch a monitor and keyboard to customize the RAID configuration on machines, not even once. Set-up the RAID controller configuration via spreadsheet, ingest it, and install. The RAID will be configured on first installation with no human interaction required.)
  • Install OS.
  • Configure OS.
  • Configure networking
    (These include configuring multiple network interfaces, multiple network types: IB, 10G, 1G, and authenticated SSH password-less access at boot.)
  • Leave you to be productive, to focus on more interesting problems.

 

With Stacki, machines are disposable. Everything is built from the ground up programmatically so recovering from disasters just means rebuilding your servers.

Machines are disposable but data is not. After the initial installation, data is preserved across reinstalls. Data drives are reformatted only by deliberate action. A reinstall is a refresh of the OS and/or application software while data on disk is preserved.

Stacki delivers certainty. If you’re configuring individual machines on a daily basis without automation, you’re losing. Our goal is to keep you from having to configure individual servers and always knowing the answer to: “What state are my servers in?”

Once your servers are installed with Stacki, augment them with your favorite configuration toolset – be it shell scripts, Salt, Chef, Puppet, CFEngine, Ansible, or homegrown – you don’t have throw away work already done. (Although, once you see what it can do, some of that post-install configuration management may be easily replaced during installation.)

Other Open Source Downloads for Stacki

With Stacki, you can add Pallets to expands the range of software available to backend nodes. The following Pallets were developed by the StackIQ engineering team and released as open source.

*Note: These Pallets do not currently work with RHEL/CentOS 6 frontends. They only work with RHEL/CentOS 7 frontends at this time.

Stacki Pallet for Docker

The Stacki Pallet for Docker runs Docker Community Edition (17.03.0), has Docker Swarm mode baked in (installs and validates it automatically) and is TLS protected. If you are interested in just Docker and Docker Swarm Mode, this is the pallet for you.

Download the following ISOs (MD5 checksum & MD5 checksum) to your frontend and visit the GitHub repo for documentation:

If you would like to add monitoring capabilities to your frontend, download the following Prometheus Pallet and visit the GitHub Repo for documentation:

Stacki Pallet for Hortonworks

Stacki enables the consistency and configuration required for a functioning Hadoop installation. This open source Hortonworks bridge pallet enables the installation of Hortonworks through the Ambari appliance. With Stacki and this Pallet, you can automate your Hadoop cluster installs quickly and efficiently.

Download the following ISOs (MD5 checksum & MD5 checksum) to your frontend and visit the Stacki-hdp-bridge GitHub repo for documentation:

If your frontend does not have internet connection, you will also have to download these ISOs (MD5 checksum):

Stacki Pallet for Kubernetes

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Stacki+Kubernetes, can deploy a Kubernetes stack on bare metal. This Pallet installed on top of Stacki, will give you a functioning Kubernetes cluster with a kubernetes-dashboard deployment if you request it.
