Amazon EKS - Kubernetes cluster on AWS

-

 1.) What is EKS?

-It is Managed Kubernetes Service

-What AWS provides through EKS:

    * AMS manages Master Nodes 

    * Necessary apps pre-installed

        **Container Runtime

        **Master Processes

    * Scaling and Backups

-You can focus on deploying your application

-You are creating only working nodes


2.) How to use EKS ?


a) basic confiruration

- Create AWS account (free tier)

- Create a VPC

- Create an IAM role with Security Group ( Create AWS user with list of permissions)

- Create Cluster Control Plane creatw with IAM role

    * choose cluster name, k8s version

    * choose region and VPC for your cluster

    * set security for your cluster

- Create Worker Nodes and connect to cluster ( EC2)

    * Create as a Node Group (group of Nodes)

    * Choose cluster it will attach to 

    * Define Security Group , select instance type, resources

    * Define max and min numbers of Nodes - Autoscaling 

- configure kubectl on local machnie to connect to remote Cluster

b) simple configuration with eksctl

- created by community

- setting up cluster with one command

brew tap weaveworks/tap

brew tap weaveworks/tap/eksctl

eksctl version

eksctl create cluster \ 
 --name test-cluster
 --version 1.17
 --region eu-central-1 \
 --nodegroup-name linux-nodes \
 --node-type t2.micro \
 --nodes 2

- destroing cluster

eksctl delete cluster --name test-cluster

I. Introduction 1. Kubernetes Overview - Kubernetes = popular container orchestrator  * it lets you schedule containers on a cluster of machines  * you can run multiple containers on one machine  * you can run long running services (like web applications)  * Kubernetes will manage the state of those containers:    ** Can start the container on specific nodeskubectl create -f pod-demo.yml    ** Will restart a container when it gets killed    ** Can move containers from one dnode to another node - you can run Kubernetes anywhere:   *on-premise (own datacenter)   *public (Google cloud, AWS)   *hybrid: public & private -highly modular -open source -backed by google -Container Orchestration = Make many servers act like one -Released by Google in 2015, maintained by large community -Runs on top of Docker (usually) as a set of APIs in containers -Provides API/CLI to managed containers across server...

 0. Overivew - Packet manager 1. Helm Provenance and Integrity - https://github.com/technosophos/k8s-helm/blob/master/docs/provenance.md - Helm has provenance tools which help chart users verify the integrity and origin of a package. Using industry-standard tools based on PKI, GnuPG, and well-respected package managers, Helm can generate and verify signature files. a) Overview   -  I ntegrity is established by comparing a chart to a provenance record. Provenance records are stored in   provenance files , which are stored alongside a packaged chart. For example, if a chart is named   myapp-1.2.3.tgz , its provenance file will be   myapp-1.2.3.tgz.prov .  -  Provenance files are generated at packaging time ( helm package --sign ... ), and can be checked by multiple commands, notable   helm install --verify . b) The workflow This section describes a potential workflow for using provenance data effectively. Prerequisites: A valid PGP keyp...

Ansible Tower / AWX

-
- Ansible Tower provides a web server interface to ansible.  - System rewuierments are somewhat heavy.  - Tower is only free for minimal use. Working with more than a few system requires a paid lincense.  - The two keys benefots of Ansible Tower are user permissioning and the audit trail (only provided with license.  - Only touched on in EX4077  - How is ansible Tower installed on your system? Ansible Tower is provided in a tarball containing binaries, config files, and an installation script that must be ran.  - To populate an Ansible Tower project with source files can be used:        * file system of the Ansible Tower server        * git        * subversion  - features:        * an interface for running Ansible plays and playbooks against target hosts.       * Separate user accounts permissioned for selective access to Tower-managed ...
