Docker to AWS, A journey

I am following this lecture to build from here: https://amigoscode.com/courses/631065/lectures/11260263

Docker Image:

Image is a template for creating an environment of your choice, snapshot, has everything to run your apps, OS, software, app code.

Below code we are pulling Apache httpd in docker desktop:

Check the images:

Run container from this image:

It will hang up so we write ctrl+c to delete it

we check with this code:

docker run

we check:

or

Docker port exposing: before that we are stopping the running container

docker stop objective_roentgen
docker stop intelligent_wiles

Now writing command for exposing the port and running the container:

d for dettach and p for port exposing t

Now the container is running perfectly and exposing the port which we can visit and check with command:

 

Now going to

will work perfectly.

It means the container port 80 is exposing to user by port 8080

Now I stopped the container:

So cannot reach to localhost:8080
Now we want to run in different port we can also follow the step:

Now we can also run multiple containers from a single command:

We stop and start again the docker container:

 

now docker help finding:

it will show like this:

removing a container from here:

we can show id  by

it will show like this:

when we need to remove running container forcefully

-f for force

Custom name for docker container:

Now stopping docker container named website

Now running again the docker container:

we check containers with command

Docker ps formatting:

 

Docker volumes: between host and controllers

pwd=present working directory

Kubernetes Diary

Tried this code from github issue and solved:

minikube start –no-vtx-check

Test :

kubectl get nodes

Deep Dive Into Cloud Computing: Docker and Kubernetes and Basics

What is docker ?
Instance of redis in my computer

Why we use docker ?
Docker makes it really easy to install and run software without worrying about setup and depenedenies

Docker ecosystem-> Docker client Docker server Docker machine Docker images Docker hub Docker compose

Used docker command:

command:

 

we are using node.js server
Docker on AWS:

npm run start = starts up a development server. For development use only
npm run test= run tests associated with the project
npm run build = build a production version of the application

We need Travis CI
AWS hosting

One question to professor:
For lab report:
Explain what is the output, what is the process and some codes. Some screenshots.
What does documentation contains is it lab report A4 page ?

Advanced Formal Modelling Excercise-1

Let Rz={(a,b)|a,b is belongs to Z^+ and a-b is an odd positive integer}.

The set of integers is represented by the letter Z. An integer is any number in the infinite set,

Z={.., -3,-2,-1, 0, 1, 2 ,3, …}
Z+ is the set of all positive integers(1,2,3,….) there is no 0 here
Z- is the set of all negative integers (…,-3,-2,-1) there is no 0 here
Z^nonneg is the set of all positive integers including 0, while Z^nonpos is the set of all negative integers including 0

Source: https://calculus.nipissingu.ca/tutorials/numbers.html#:~:text=An%20integer%20is%20any%20number,%2D2%2C%20%2D1).

Soln:
Set R1 is reflexive because
Q1) For every a is belongs to Z+ . (a,a) is belongs to R . a-a = 0 is not an odd  number. So, R is not reflexive.

For every a,b is belongs to Z+ : if a,b is positive, then b-a is negative. That if( a,b) is belongs R then (b,a) is not belongs to R. So not symmetric.

Due to the same reason, as above, (a,b) and (b,a) cannot be simultaneously in R . So the condition in the definition of anti symmetry is false.

The implication holds trivially , R is anti symmetric.

Cloud Computing Lectures and Notes Winter 2020/21

1st week:
Task: Choose a team with topic is the exercise.

You need to chose a software solution, you need make it and present.
You need to submit it before February and every week prof. needs update
It should be multi node implementation

No exam this time only project that mean

Your installation guide should provide detailed steps how to deploy,
configure and use the service

The client-server architecture consists of 2 layers and is called two-tier model
(tier = layer)

Parental Computing is company provided the service[47 minutes in recording]

According to their areas of responsibility, 4 types of clients exist:
1 Text-/X-Terminals
2 Thin/Zero Clients
3 Applet Clients
4 Fat Clients

— My Topic For Project: Kubernetes and Docker
– Most of the cloud/DevOps engineer needs this skill and First experience in the public cloud environment (AWS or AZURE)
– good knowledge of object-oriented languages ​​(e.g. Java, Python, PowerShell or NET) and containerization strategies

References:
https://www.educative.io/blog/roadmap-to-cloud-engineer-jobs
https://www.educative.io/courses/cloud-computing-101-master-the-fundamentals

The goal of the project:
|Linux administration
Documentation reading
Architecture Building
Not so hardcore programming
If you don’t do project you will fail

 

2nd week:
We shared our topic name maybe we may change the topic name if needed.
Topic: Content Delivery Network with Kubernetes and Docker
We have 3 team members, Syed Ahmed Zaki, Daniel Von Barany, Kranthi kumar reddy Kasireddy
– We want to make a system in different server which distributes content like images, mp3, text known as content delivery networking
-We are very new to Kubernetes and Docker still researching about this
– We want to deploy in cloud maybe Minio in multi node environment or openNebula it is serverless
– It will be scalable
– Any of your suggestion Prof. ?
– My other team members and colleagues will share the details

Learned from Youtube this week about Docker and little bit Kubernetes

 

3rd week:
Notes from class lecture:
Heteregenous is better because one system and multi computer
Failover and Failback
