Lots of things happen here. Smart things. Funny things. Questions whose answer is usually 'RTFM' except we know how to say it nicely. Well, some of us do.

What is Stacki?

Stacki is a CentOS/RHEL/SLES 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.

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 repositories for all backend machines. All machines will be at the latest kernel and RPM revisions of the OS and installed applications.

I know whatever, what does Stacki do?

  • Install OS.
  • Configure OS.
  • 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.
  • Configure networking. This includes configuring multiple network interfaces, multiple network types: IB, 10G, 1G, and authenticated SSH password-less access at boot.
  • Machines are disposable. Everything is built from the ground up programmatically. Recovering from disasters is a simple rebuild.
  • Data is preserved across reinstalls.
  • Integrates with DevOps tools: Ansible, Puppet, Chef, Salt.
  • Leave you to be productive, to focus on more interesting problems.

stacki's Issues

Translate MS excel spreadsheets to Unix

Install the 'dos2unix' package on the frontend, then preprocess all spreadsheets through dos2unix to translate all MS characters to a Unix compatible format.

iptables-services

Kranti, our bug bounty hunter, discovered backend nodes cannot route through the frontend to get internet access. This is because iptables is on, but in 7.x RHEL/CentOS the actual service files are broken into iptables and iptables-services rpms.

Investigate Creating Updates.img on a StackI frontend.

  • Currently stacki does not offer a way to make changes to the installer. initrd.img, and install.img are created during build, and are not modified.
  • Products.img is built on the frontend during distribution creation.
  • updates.img is not used anymore and may be a good avenue for making changes to the installer at a customer site.

man_db.conf vs. man.config

In redhat 7.x they seem to be using /etc/man_db.conf instead of /etc/man.config. MANPATH entries need to be appended to /etc/man_db.conf and not man.config.

It also needs to be MANDATORY_MANPATH and no just plain 'ole MANPATH.

Plugin-based Intrinsic attribute computation

  1. Intrinsic attributes are currently part of the mainline StackI command line process.
  2. They are not extensible.
  3. Change the intrinsic attribute computation to a plugin based architecture, so that any customer can
    define attributes that are computed (as opposed to stored).

Examples:

  1. Attribute that is a list of all hosts in a cluster that have zookeeper attribute set to true
  2. Attribute that is a list of all non-root disks of a machine.

Support for Multiple DVDs during Installation

Currently, the only way to add pallets during installation is over the network using a central server.
We need to ability to supply pallets from multiple DVDs during installation (As it used to be for StackIQ 6.6).

The changes should be made in the wizard.

  1. When an admin clicks on "Add Pallets", the dialog box that opens should allow for adding pallet using DVD along with adding pallets through the network.
  2. When pallets have been selected using multiple DVDs, the "Download Pallets" window should eject an existing DVD, and inform the user to insert a new DVD for download.

Wiki - How To for VirtualBox

Document process of build a Frontend and Backend in VirtualBox. Disk/RAM requirement and VirtualBox networking.

private - host only
public - NAT network

The "NAT network" means you can ssh from your host environment directly onto the Frontend.
