### Red Hat CodeReady Containers (CRC) on WSL

[Back to the Top](#table-of-contents)

[Red Hat CodeReady Containers (CRC)](https://developers.redhat.com/content-gateway/rest/mirror/pub/openshift-v4/clients/crc/2.9.0) is a tool that provides a minimal, preconfigured OpenShift 4 cluster on a laptop or desktop machine for development and testing purposes. CRC is delivered as a platform inside of the VM.

* **odo (OpenShift Do)**, a CLI tool for developers, to manage application components on the OpenShift Container Platform.
 
 
 <img src="https://user-images.githubusercontent.com/45159366/193531714-a4316c2c-4ba9-4d31-86cf-7a3edc6f6375.png">

**System Requirements:**

* **OS:** CentOS Stream 8/RHEL 8/Fedora or later (the latest 2 releases).
   * **Download:** [pull-secret](https://cloud.redhat.com/openshift/install/crc/installer-provisioned?intcmp=701f20000012ngPAAQ)
   * **Login:** [Red Hat account](https://access.redhat.com/login)

**Other physical requirements include:**

* Four virtual CPUs (**4 vCPUs**)
   * 10GB of memory (**RAM**)
   * 40GB of storage space

**To set up CodeReady Containers, start by creating the ```crc``` directory, and then download and extract the ```crc``` package:**

```mkdir /home/<user>/crc```

```wget https://mirror.openshift.com/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz```

```tar -xvf crc-linux-amd64.tar.xz```

**Next, move the files to the crc directory and remove the downloaded package(s):**

```mv /home/<user>/crc-linux-<version>-amd64/* /home/<user>/crc```

```rm /home/<user>/crc-linux-amd64.tar.xz```

```rm -r /home/<user>/crc-linux-<version>-amd64```

**Change to the ```crc``` directory, make ```crc``` executable, and export your ```PATH``` like this:**

```cd /home/<user>/crc```

```chmod +x crc```

```export PATH=$PATH:/home/<user>/crc```

**Set up and start the cluster:**

```crc setup```

```crc start -p /<path-to-the-pull-secret-file>/pull-secret.txt```

**Set up the OC environment:**

```crc oc-env```

```eval $(crc oc-env)```

**Log in as the developer user:**

```oc login -u developer -p developer https://api.crc.testing:6443```

```oc logout```

**And then, log in as the platform’s admin:**

```oc login -u kubeadmin -p password https://api.crc.testing:6443```

```oc logout```

#### Interacting with the cluster. The most common ways include:

**Starting the graphical web console:**

```crc console```

**Display the cluster’s status:**

```crc status```

**Shut down the OpenShift cluster:**

```crc stop```

**Delete or kill the OpenShift cluster:**

```crc delete```

### Setting up Podman on WSL

[Back to the Top](#table-of-contents)

[Podman (the POD manager)](https://podman.io/) is an open source tool for developing, managing, and running containers on your Linux® systems. It also manages the entire container ecosystem using the libpod library.  Podman’s daemonless and inclusive architecture makes it a more secure and accessible option for container management, and its accompanying tools and features, such as [Buildah](https://www.redhat.com/en/topics/containers/what-is-buildah) and [Skopeo](https://www.redhat.com/en/topics/containers/what-is-skopeo), allow developers to customize their container environments to best suit their needs.

* Fedora: ```sudo dnf install podman```
 * CentOS: ```sudo yum --enablerepo=extras install podman```
 * Ubuntu 20.04 or later: ```sudo apt install podman```
 * Debian 11 (bullseye) or later, or sid/unstable: ```sudo apt install podman```
 * ArchLinux: ```sudo pacman -S podman``` and then tweaks for rootless

### Setting up Buildah on WSL

[Back to the Top](#table-of-contents)

[Buildah](https://buildah.io/) is an open source, Linux-based tool that can build Docker- and Kubernetes-compatible images, and is easy to incorporate into scripts and build pipelines. In addition, Buildah has overlap functionality with [Podman](https://podman.io/), [Skopeo](https://github.com/containers/skopeo), and [CRI-O](https://cri-o.io/).

* Fedora: ```sudo dnf -y install buildah```
 * CentOS: ```sudo yum --enablerepo=extras install buildah```
 * Ubuntu 20.04 or later: ```sudo apt install buildah```
 * Debian 11 (bullseye) or later, or sid/unstable: ```sudo apt install -y buildah```
 * ArchLinux: ```sudo pacman -S buildah``` and then tweaks for rootless

### Installing Kubernetes on WSL with Rancher Desktop

[Back to the Top](#table-of-contents)

[Rancher Desktop](https://www.rancher.com/products/rancher-desktop) is an open-source desktop application for Mac, Windows and Linux. Rancher Desktop runs Kubernetes and container management on your desktop letting you choose the version of Kubernetes you want to run. It can also build, push, pull, and run container images using either the Docker CLI (with Moby/dockerd) or nerdctl (with containerd).

**Features:**

* Installs a new Linux VM in WSL2 that has a Kubernetes cluster based on [k3s](https://k3s.io/) as well as installs various components in it such as KIM (for building docker images on the cluster) and the [Traefik Ingress Controller](https://traefik.io/solutions/kubernetes-ingress/).
 
 * It installs the kubectl and Helm CLIs on the Windows side linked to them.
 
 * A nice Windows app to manage its settings and help facilitate its upgrades.

 Enable the WSL 2 base engine in Docker Desktop

We also need to set in Resources which WSL2 distribution we want to access Docker from, as shown below using Ubuntu 20.04. Then remember to restart Docker for Windows, and once the restart is complete we can use the docker command from within WSL:

Make sure to use kind as a simple way to run Kubernetes in a container. Here we will install the instructions from the official [Kind website](https://kind.sigs.k8s.io/docs/user/quick-start/).

```curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.16.0/kind-$(uname)-amd64```

```chmod +x ./kind```

```mv ./kind /usr/local/bin/```

Now that kind is installed, we can create the Kubernetes cluster

```echo $KUBECONFIG```

```ls $HOME/.kube```

```kind create cluster --name wslkube```

```ls $HOME/.kube```

We have successfully created a single-node Kubernetes cluster.

```kubectl get nodes```

```kubectl get all --all-namespaces```

### Installing Kubernetes on WSL with Microk8s

[Back to the Top](#table-of-contents)

* **Note:** This install option requires systemd to be running on WSL

* **WSL Systemd requirements:** Windows 11 and a version of WSL 0.67.6 or above.

[MicroK8s](https://microk8s.io/) is the simplest production-grade upstream Kubernets setup to get up and running.

Installing Microk8s

```sudo snap install microk8s --classic```

Checking the status while Kubernetes starts

```microk8s status --wait-ready```

Turning on the services you want

```microk8s enable dashboard dns registry istio```

Try **microk8s enable --help** for a list of available services and optional features. **microk8s disable <name>** turns off a service.

Start using Kubernetes

```microk8s kubectl get all --all-namespaces```

If you mainly use MicroK8s you can make our kubectl the default one on your command-line with **alias mkctl="microk8s kubectl"**.

Access the Kubernetes dashboard

```microk8s dashboard-proxy```

### Setting up on Microsoft Azure

[Back to the Top](#table-of-contents)

[Microsoft Azure Red Hat OpenShift](https://learn.microsoft.com/en-us/azure/openshift/) is a fully managed offering of OpenShift running in Azure. This service is jointly managed and supported by [Microsoft](https://www.microsoft.com) and [Red Hat](https://redhat.com/).

**Requirements:**

* [Azure CLI](https://learn.microsoft.com/en-us/cli/azure/) version 2.6.0 or later.

* **56 vCPUs**, so you must increase the account limit.

By default, each cluster creates the following instances:

* One bootstrap machine, which is removed after installation

* Three control plane machines

* Three compute machines

Because the bootstrap, control plane, and worker machines use ```Standard_DS4_v2``` virtual machines, which use **8 vCPUs**, a default cluster requires **56 vCPUs**. The bootstrap node VM is used only during installation. To deploy more worker nodes, enable autoscaling, deploy large workloads, or use a different instance type, you must further increase the vCPU limit for your account to ensure that your cluster can deploy the machines that you require.

* **1 VNet.** Each default cluster requires one Virtual Network (VNet), which contains two subnets.

* **7 Network interfaces.** Each default cluster requires seven network interfaces. If you create more machines or your deployed workloads create load balancers, your cluster uses more network interfaces.

* **2 Network security groups.** Each cluster creates network security groups for each subnet in the VNet. The default cluster creates network security groups for the control plane and for the compute node subnets:
controlplane

* Allows the control plane machines to be reached on port 6443 from anywhere.
node

* Allows worker nodes to be reached from the internet on ports 80 and 443.

* **3 Network load balancers.** Each cluster creates the following load balancers:
default

* Public IP address that load balances requests to ports 80 and 443 across worker machines
internal

* Private IP address that load balances requests to ports 6443 and 22623 across control plane machines
external

* Public IP address that load balances requests to port 6443 across control plane machines

* **Note:** If your applications create more Kubernetes LoadBalancer service objects, your cluster uses more load balancers.

* **2 Public IP addresses.** The public load balancer uses a public IP address. The bootstrap machine also uses a public IP address so that you can SSH into the machine to troubleshoot issues during installation. The IP address for the bootstrap node is used only during installation.

* **7 Private IP addresses.** The internal load balancer, each of the three control plane machines, and each of the three worker machines each use a private IP address.

#### Minimum Requirements:

* [gcloud CLI](https://cloud.google.com/sdk/gcloud/) or [OpenShift CLI (oc)](https://access.redhat.com/downloads/content/290).
 
**Master Nodes:**
 
   * Minimum 4 vCPU (additional are strongly recommended).

* Minimum 16 GB RAM (additional memory is strongly recommended, especially if etcd is co-located on masters).

* Minimum 40 GB hard disk space for the file system .
 
**Worker Nodes:**
 
   * 1 vCPU.

* Minimum 8 GB RAM.

* Minimum 15 GB hard disk space for the file system.
 
 * If you don’t have a GCP account already, [sign-up for Cloud Platform](https://cloud.google.com/free-trial/), setup billing and activate APIs.
 
 * Setup a service account. A service account is a way to interact with your GCP resources by using a different identity than your primary login and is generally intended for server-to-server interaction. From the GCP Navigation Menu, click on **"Permissions."**

* Click on **"Service accounts."**
 
 
 <img src="https://user-images.githubusercontent.com/45159366/195022808-4b4fbe2f-d04f-4ef1-b1a7-dda46df4869e.PNG">
 

 
Click on **"Create service account,"** which will prompt you to enter a [service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#overview) name. Provide a name for your project and click on **"Furnish a new private key."** The default **"JSON"** Key type should be left selected.

Once you click **"Create,"** a service account **“.json”** will be downloaded to your browser’s downloads location.

* **Important:** Like any credential, this represents an access mechanism to authenticate and use resources in your GCP account. Never place this file in a publicly accessible source repo (Public GitHub or GitLab).
 
 using the JSON credential via a Kubernetes secret deployed to your OpenShift cluster. To do so, first perform a base64 encoding of your JSON credential file:
 
 ``` base64 -i ~/path/to/downloads/credentials.json```
 
 Keep the output (a very long string) ready for use in the next step, where you’ll replace ```‘BASE64_CREDENTIAL_STRING’``` in the pod example (below) with the output just captured from base64 encoding.
 
 * **Note:** base64 is encoded (not encrypted) and can be readily reversed, so this file (with the base64 string) is just as confidential as the credential file above. 
 
 Create the [Kubernetes secret](http://kubernetes.io/docs/user-guide/secrets/) inside your OpenShift Cluster. A secret is the proper place to make sensitive information available to pods running in your cluster (like passwords or the credentials downloaded in the previous step).
 
 ```
apiVersion: v1
kind: Secret
metadata:
  name: google-services-secret
type: Opaque
data:
  google-services.json: BASE64_CREDENTIAL_STRING
```

**Note:** Replace ```‘BASE64_CREDENTIAL_STRING’``` with the base64 output from the prior step.

**Deploy the secret to the cluster:**

```oc create -f google-secret.yaml```

This generally infers that a connection is built before the data transfer (by following the procedures laid out in a protocol) and then is deconstructed at the at the end of the data transfer.

- Packet: A packet is, generally speaking, the most basic unit that is transferred over a network. When communicating over a network, packets are the envelopes that carry your data (in pieces) from one end point to the other.

Packets have a header portion that contains information about the packet including the source and destination, timestamps, network hops. The main portion of a packet contains the actual data being transferred. It is sometimes called the body or the payload.

- Network Interface: A network interface can refer to any kind of software interface to networking hardware. For instance, if you have two network cards in your computer, you can control and configure each network interface associated with them individually.

A network interface may be associated with a physical device, or it may be a representation of a virtual interface. The "loop-back" device, which is a virtual interface to the local machine, is an example of this.

- LAN: LAN stands for "local area network". It refers to a network or a portion of a network that is not publicly accessible to the greater internet. A home or office network is an example of a LAN.

- WAN: WAN stands for "wide area network". It means a network that is much more extensive than a LAN. While WAN is the relevant term to use to describe large, dispersed networks in general, it is usually meant to mean the internet, as a whole.
If an interface is connected to the WAN, it is generally assumed that it is reachable through the internet.

- Protocol: A protocol is a set of rules and standards that basically define a language that devices can use to communicate. There are a great number of protocols in use extensively in networking, and they are often implemented in different layers.

Some low level protocols are TCP, UDP, IP, and ICMP. Some familiar examples of application layer protocols, built on these lower protocols, are HTTP (for accessing web content), SSH, TLS/SSL, and FTP.

- Port: A port is an address on a single machine that can be tied to a specific piece of software. It is not a physical interface or location, but it allows your server to be able to communicate using more than one application.

- Firewall: A firewall is a program that decides whether traffic coming into a server or going out should be allowed. A firewall usually works by creating rules for which type of traffic is acceptable on which ports. Generally, firewalls block ports that are not used by a specific application on a server.

- NAT: Network address translation is a way to translate requests that are incoming into a routing server to the relevant devices or servers that it knows about in the LAN. This is usually implemented in physical LANs as a way to route requests through one IP address to the necessary backend servers.

- VPN: Virtual private network is a means of connecting separate LANs through the internet, while maintaining privacy. This is used as a means of connecting remote systems as if they were on a local network, often for security reasons.

## Network Layers

While networking is often discussed in terms of topology in a horizontal way, between hosts, its implementation is layered in a vertical fashion throughout a computer or network. This means is that there are multiple technologies and protocols that are built on top of each other in order for communication to function more easily. Each successive, higher layer abstracts the raw data a little bit more, and makes it simpler to use for applications and users. It also allows you to leverage lower layers in new ways without having to invest the time and energy to develop the protocols and applications that handle those types of traffic.

As data is sent out of one machine, it begins at the top of the stack and filters downwards. At the lowest level, actual transmission to another machine takes place. At this point, the data travels back up through the layers of the other computer. Each layer has the ability to add its own "wrapper" around the data that it receives from the adjacent layer, which will help the layers that come after decide what to do with the data when it is passed off.

One method of talking about the different layers of network communication is the OSI model. OSI stands for [Open Systems Interconnect](https://en.wikipedia.org/wiki/OSI_model).This model defines seven separate layers. The layers in this model are:

- Application: The application layer is the layer that the users and user-applications most often interact with. Network communication is discussed in terms of availability of resources, partners to communicate with, and data synchronization.

- Presentation: The presentation layer is responsible for mapping resources and creating context. It is used to translate lower level networking data into data that applications expect to see.

- Session: The session layer is a connection handler. It creates, maintains, and destroys connections between nodes in a persistent way.

- Transport: The transport layer is responsible for handing the layers above it a reliable connection. In this context, reliable refers to the ability to verify that a piece of data was received intact at the other end of the connection. This layer can resend information that has been dropped or corrupted and can acknowledge the receipt of data to remote computers.

- Network: The network layer is used to route data between different nodes on the network. It uses addresses to be able to tell which computer to send information to. This layer can also break apart larger messages into smaller chunks to be reassembled on the opposite end.

- Data Link: This layer is implemented as a method of establishing and maintaining reliable links between different nodes or devices on a network using existing physical connections.

- Physical: The physical layer is responsible for handling the actual physical devices that are used to make a connection. This layer involves the bare software that manages physical connections as well as the hardware itself (like Ethernet).

The TCP/IP model, more commonly known as the Internet protocol suite, is another layering model that is simpler and has been widely adopted.It defines the four separate layers, some of which overlap with the OSI model:

- Application: In this model, the application layer is responsible for creating and transmitting user data between applications. The applications can be on remote systems, and should appear to operate as if locally to the end user.
The communication takes place between peers network.

- Transport: The transport layer is responsible for communication between processes. This level of networking utilizes ports to address different services. It can build up unreliable or reliable connections depending on the type of protocol used.

- Internet: The internet layer is used to transport data from node to node in a network. This layer is aware of the endpoints of the connections, but does not worry about the actual connection needed to get from one place to another. IP addresses are defined in this layer as a way of reaching remote systems in an addressable manner.

- Link: The link layer implements the actual topology of the local network that allows the internet layer to present an addressable interface. It establishes connections between neighboring nodes to send data.

### Interfaces
**Interfaces** are networking communication points for your computer. Each interface is associated with a physical or virtual networking device. Typically, your server will have one configurable network interface for each Ethernet or wireless internet card you have. In addition, it will define a virtual network interface called the "loopback" or localhost interface. This is used as an interface to connect applications and processes on a single computer to other applications and processes. You can see this referenced as the "lo" interface in many tools.

## Network Protocols

Networking works by piggybacks on a number of different protocols on top of each other. In this way, one piece of data can be transmitted using multiple protocols encapsulated within one another.

**Media Access Control(MAC)** is a communications protocol that is used to distinguish specific devices. Each device is supposed to get a unique MAC address during the manufacturing process that differentiates it from every other device on the internet. Addressing hardware by the MAC address allows you to reference a device by a unique value even when the software on top may change the name for that specific device during operation. Media access control is one of the only protocols from the link layer that you are likely to interact with on a regular basis.

**The IP protocol** is one of the fundamental protocols that allow the internet to work. IP addresses are unique on each network and they allow machines to address each other across a network. It is implemented on the internet layer in the IP/TCP model. Networks can be linked together, but traffic must be routed when crossing network boundaries. This protocol assumes an unreliable network and multiple paths to the same destination that it can dynamically change between. There are a number of different implementations of the protocol. The most common implementation today is IPv4, although IPv6 is growing in popularity as an alternative due to the scarcity of IPv4 addresses available and improvements in the protocols capabilities.

**ICMP: internet control message protocol** is used to send messages between devices to indicate the availability or error conditions. These packets are used in a variety of network diagnostic tools, such as ping and traceroute. Usually ICMP packets are transmitted when a packet of a different kind meets some kind of a problem. Basically, they are used as a feedback mechanism for network communications.

**TCP: Transmission control protocol** is implemented in the transport layer of the IP/TCP model and is used to establish reliable connections. TCP is one of the protocols that encapsulates data into packets. It then transfers these to the remote end of the connection using the methods available on the lower layers. On the other end, it can check for errors, request certain pieces to be resent, and reassemble the information into one logical piece to send to the application layer. The protocol builds up a connection prior to data transfer using a system called a three-way handshake. This is a way for the two ends of the communication to acknowledge the request and agree upon a method of ensuring data reliability. After the data has been sent, the connection is torn down using a similar four-way handshake. TCP is the protocol of choice for many of the most popular uses for the internet, including WWW, FTP, SSH, and email. It is safe to say that the internet we know today would not be here without TCP.

**UDP: User datagram protocol** is a popular companion protocol to TCP and is also implemented in the transport layer. The fundamental difference between UDP and TCP is that UDP offers unreliable data transfer. It does not verify that data has been received on the other end of the connection. This might sound like a bad thing, and for many purposes, it is. However, it is also extremely important for some functions. It’s not required to wait for confirmation that the data was received and forced to resend data, UDP is much faster than TCP. It does not establish a connection with the remote host, it simply fires off the data to that host and doesn't care if it is accepted or not. Since UDP is a simple transaction, it is useful for simple communications like querying for network resources. It also doesn't maintain a state, which makes it great for transmitting data from one machine to many real-time clients. This makes it ideal for VOIP, games, and other applications that cannot afford delays.

**HTTP: Hypertext transfer protocol** is a protocol defined in the application layer that forms the basis for communication on the web. HTTP defines a number of functions that tell the remote system what you are requesting. For instance, GET, POST, and DELETE all interact with the requested data in a different way.

**FTP: File transfer protocol** is in the application layer and provides a way of transferring complete files from one host to another. It is inherently insecure, so it is not recommended for any externally facing network unless it is implemented as a public, download-only resource.

**DNS: Domain name system** is an application layer protocol used to provide a human-friendly naming mechanism for internet resources. It is what ties a domain name to an IP address and allows you to access sites by name in your browser.

**SSH: Secure shell** is an encrypted protocol implemented in the application layer that can be used to communicate with a remote server in a secure way. Many additional technologies are built around this protocol because of its end-to-end encryption and ubiquity. There are many other protocols that we haven't covered that are equally important. However, this should give you a good overview of some of the fundamental technologies that make the internet and networking possible.
