-# A Macroscopic View
-
----
-
-## Macroscopic Items
-
-* The business case for containers
-
-* The problem containers are solving
-
-* What applications need
-
-* What is the OS doing provides?
-
----
-
-## What do CIOs worry about?
-
-Who are the CIO's customers?
-
-* Business Units: Need Computers to Run Applications
-  * Peak Capacity
-
-* CFO: Demanding Budget Justifications
-  * Spend Less
-
----
-
-## History of Solutions
-
-For Each Business Application Buy a Machine
-
-* Buy a machine for each application
-
-  * Big enough for Peak Load (CPU, Memory, Disk)
-  
-The Age of VMs
-
-* Buy bigger machines and chop them up into logical machines
-
-  * Distribute your applications as VMs theses machines
-
-* Observe what and when the application load  actually is
-
-  * Possibly rebalance be to inform possibly moving
-
-But Maintaining Machines (Bare Metal or VM) is hard (Patches, Packages, Drivers, etc)
-
----
-
-## What Developers and Ops worry about
-
-* Getting Software deployed
-
-* Mysterious reasons why deployed application doesn't work
-
-    * Developer to Ops:
-
-        * "Hey it works on my development machine..."
-        
-        * "I don't know why it isn't working for ***you***"
-
-        * "Everything ***looks*** the same"
-
-        * "I have no idea what could be different"  
-
----
-
-## The History of Software Deployment
-
-Software Deployment is just a reproducible way to install files:
-
-* Cards
-
-* Tapes
-
-* Floppy Disks
-
-* Zip/Tar Files
-
-* Installation "Files" (rpm/deb/msi)
-
-* VM Images
-
----
-
-## What is the Problem Containers are Solving?
-
-It depends on who you are:
-
-  * For the CIO: Better resource utilization
-
-  * For Ops: Software Distribution
-  
-  * For the Developer & Ops: Reproducible Environment
-
-<BR><BR>
-
-Ummm, but what exactly are containers....

-
-## Macroscopic view: Applications and the OS
-
-Applications:
-
-* What are the inputs/outputs to a program?
-
-The OS:
-
-* What does the OS provide?
-
----
-
-## What are the inputs/outputs to a program?
-
-Explicitly:
-* Command Line Arguments
-* Environment Variables
-* Standard In
-* Standard Out/Err
-
-Implicitly (via the File System):
-
-* Configuration Files
-* Other Installed Applications
-* Any other files
-
-Also Implicitly
-
-* Memory
-* Network
-
-    
----
-
-
-## What does the OS provide?
-
-* OS Kernel
-    * Kernel loded at boot time
-        * Sets up disk drives, network cards, other hardware, etc
-        * Manages all hardware, processes, memory, etc
-    * Kernel Space
-        * Low level innards of Kernel (fluid internal API)
-        * No direct access by applications of most Kernel functionality
-
-
-* User Space (userland) Processes
-    * Code running outside the Kernel
-    * Very stable shim library access from User Space to Kernel Space (Think "fopen")
-
-* The "init" Process
-    * User Space Process run after Kernel has booted
-    * Always PID 1
-
----
-
-## OS Processes
-
-* Created when an application is launched
-    *  Each has a unique Process ID (PID)
-
-* Provides it its own logical 'view' of all implicit inputs/output when launching app
-    * File System ( root directory, / )
-    * Memory
-    * Network Adaptors
-    * Other running processes
-
----
-
-## What do we mean by "The OS"
-
-Different Linux's
-
-* Ubuntu / Debian; Centos / RHEL; Raspberry Pi; etc
-
-What do they have in common?
-
-* They all have a kernel that provides access to Userland (ie fopen)
-
-* They typically have all the commands (bash, sh, ls, grep, ...)
-
-What may be different?
-
-* May use different versions of the Kernel (4.18, 5.4, ...)
-    * Internally different, but providing same Userland API
-
-* Many other bundled commands, packages and package management tools
-    * Namely what makes it 'Debian' vs 'Centos'
-
----
-
-## What might a 'Minimal' Linux be?
-
-You could actually just have:
-
-* A Linux Kernel
-
-* An application (for simplicity a statically linked C program)
-
-* The kernel configured to run that application as its 'init' process
-
-Would you ever do this?
-
-* Why not? 
-
-    * It certainly would be very secure
-    
----
-
-## So Finally... What are Containers?
-
-Containers just a Linux process that 'thinks' it is it's own machine
-
-* With its own 'view' of things like:
-    * File System ( root directory, / ), Memory, Network Adaptors, Other running processes
-
-* Leverages our understanding that a (logical) Linux Machine is 
-    * A kernel
-    * A bunch of files ( Maybe a few Environment Variables )
-
-Since it is a process running on a host machine
-
-* It uses the kernel of the host machine
-* And of course you need some tools to create the running container process
-
----
-
-## Container Runtimes and Container Images
-
-The Linux kernel actually has no concept of a container.
-
-* There have been many 'container' technologies
-
-* See [A Brief History of containers: From the 1970's till now](https://blog.aquasec.com/a-brief-history-of-containers-from-1970s-chroot-to-docker-2016)
-
-* Over the years more capabilities have been added to the kernel to make it easier
-
-<BR>
-A 'Container technology' is:
-
-* A Container Image Format of the unit of software deployment
-    * A bundle of all the files and miscellaneous configuration 
-
-* A Container Runtime Engine
-    * Software that takes a Container Image and creates a running container
-
----
-
-## The Container Runtime War is now Over
-
-The Cloud Native Computing Foundation (CNCF) has standardized containers
-
-* A standard container image format
-
-* A standard for building and configuring container runtimes
-
-* A standard REST API for loading/downloading container image to a registries 
-
-There primary Container Runtimes are:
-
-* containerd: using the 'docker' Command Line Interface (or Kubernetes)
-
-* CRI-O: using the 'podman' Command Line Interface (or Kubernetes/OpenShift)
-
-* Others exists, for example Singularity which has a history in HPC
-
----
-
-## Linux Namespaces Makes Containers Possible
-
-- Provide processes with their own isolated view of the system.
-
-    - Namespaces limit what you can see (and therefore, what you can use).
-
-- These namespaces are available in modern kernels:
-
-  - pid: processes
-  - net: network
-  - mnt: root file system (ie chroot)
-  - uts: hostname
-  - ipc
-  - user: UID/GID mapping
-  - time: time
-  - cgroup: Resource Monitoring and Limiting
-
-- Each process belongs to one namespace of each type.
-
----
-
-## Namespaces are always active
-
-- Namespaces exist even when you don't use containers.
-
-- This is a bit similar to the UID field in UNIX processes:
-
-  - all processes have the UID field, even if no user exists on the system
-
-  - the field always has a value / the value is always defined
-    <br/>
-    (i.e. any process running on the system has some UID)
-
-  - the value of the UID field is used when checking permissions
-    <br/>
-    (the UID field determines which resources the process can access)
-
-- You can replace "UID field" with "namespace" above and it still works!
-
-- In other words: even when you don't use containers,
-  <br/>there is one namespace of each type, containing all the processes on the system.

-## Terminals
-
-Once in a while, the instructions will say:
-<br/>"Open a new terminal."
-
-There are multiple ways to do this:
-
-- create a new window or tab on your machine, and SSH into the VM;
-
-- use screen or tmux on the VM and open a new window from there.

-You are welcome to use the method that you feel the most comfortable with.

-
-[Tmux](https://en.wikipedia.org/wiki/Tmux) is a terminal multiplexer like `screen`.
-
-*You don't have to use it or even know about it to follow along.
-<br/>
-But some of us like to use it to switch between terminals.

-It has been preinstalled on your workshop nodes.*
-
-- Ctrl-b c → creates a new window
-- Ctrl-b n → go to next window
-- Ctrl-b p → go to previous window
-- Ctrl-b " → split window top/bottom
-- Ctrl-b % → split window left/right
-- Ctrl-b Alt-1 → rearrange windows in columns
-- Ctrl-b Alt-2 → rearrange windows in rows
-- Ctrl-b arrows → navigate to other windows
-- Ctrl-b d → detach session
-- tmux attach → re-attach to session
