Docker - Containers

Pritesh Bhoi — Fri, 24 Jun 2022 05:11:03 +0000

Containers are instances of Docker images that can be run using the Docker run command. The main purpose of Docker is to run containers. Let's discuss how to work with containers.

Running container
Container execution is controlled by the Docker run command. To start a container in interactive mode, first start a Docker container.

sudo docker run - it centos/bin/bash

Listing of Containers
The docker ps command can be used to list all the containers on a computer. This command is used to return the running container.

Docker - Storage

storage drive

Docker has several storage drivers that make it possible to work with simple storage devices. The following table shows the different storage drivers along with the technology used for the storage drivers.

AUFS

This is a stable driver; can be used for series-ready applications.
It has good memory usage and is perfect for providing a smooth Docker container experience.
There is a high level of logging activity associated with this driver that should be taken into account.
This is great for systems that are a platform as a service type.

Device mapper

This is a stable driver; provides a seamless Docker experience.
This driver is great for testing lab applications.
This driver is compatible with the basic functionality of the Linux kernel.

Btrfs

This driver is compatible with the basic functionality of the Linux kernel.
There is a high level of logging activity associated with this driver that should be taken into account.
This driver is useful for cases where you support multiple build sets.

ZFS

It is a stable driver and is good for testing applications in the lab.
This is great for systems that work as a platform as a service.

Ovelay

It is a stable driver and conforms to the basic functionality of the Linux kernel.
Has good memory usage.
This driver is good for testing applications in the lab.

Docker components

Docker has the following components:

Docker for Mac - Allows Docker containers to run on Mac OS.

Docker for Linux - Allows Docker containers to run on Linux OS.

Docker for Windows - Allows Docker containers to run on Windows operating systems.

Docker Engine - Used to create Docker images and Docker containers.

Docker Hub - This is the registry used to host various Docker images.

Docker Compose - Used to define applications that use multiple Docker containers.

Docker features

Docker features

Docker is able to reduce development effort by providing a smaller operating system footprint via containers.
Containers make it easy for teams across departments such as development, QA, and operations to work seamlessly between applications.
You can use Docker containers anywhere, on any physical and virtual machine, even in the cloud.
Because Docker containers are quite light, they are very easy to scale.

Docker - Overview

Pritesh Bhoi — Fri, 24 Jun 2022 04:55:25 +0000

Docker is a container management service. Docker's buzzword is development, delivery and execution everywhere. The whole idea of Docker is that developers can easily develop applications and ship them in containers, which can then be deployed anywhere.

Docker was originally released in March 2013 and has since become the buzzword for modern global developments, especially when it comes to agile projects.

The official Docker site is https://www.docker.com/ This site contains all the information and documentation for the Docker software. It also has download links for different operating systems.

AWS Site-to-Site VPN introduces Private IP VPNs

Pritesh Bhoi — Thu, 23 Jun 2022 04:54:48 +0000

To date, AWS Site-to-Site VPN supports the ability to set up an IPSec VPN connection over Direct Connect with private IP addresses. This change will allow customers to encrypt DX traffic between their on-site network and AWS without the need for public IP addresses, which will also allow for better security and privacy on the network. AWS Site-to-Site VPN is a fully managed service that creates a secure connection between your data center or branch office and your AWS resources using IP Security Tunnels (IPSec). Until now, you had to use a public IP address to connect local networks to AWS VPC. Many customers require strong Direct Connect network traffic encryption and are not allowed to use public IP addresses for this communication. With this launch, you can configure private IP addresses (RFC1918) in their IPSec VPN tunnels with Direct Connect and ensure that traffic between AWS and the local network is both encrypted and private. This feature improves your overall security position and allows you to follow any security rules or commands more. To get started, create a private IP VPN connection with the AWS gateway in Direct Connect and enter the remote IP address type as the private IP. You must specify the appropriate Transit Gateway Direct Connect extension that you want to use as the carrier for this private IP VPN connection. You can route traffic over a private IP VPN connection between AWS and your network remotely using BGP (Dynamic) or by configuring static routes in the Transit Gateway routing tables. This feature is available through the AWS Management Console, the Amazon Command Line Interface (Amazon CLI) and the Amazon Software Development Kit (Amazon SDK). Private IP VPN support is available in all AWS areas where AWS Site-to-site VPN is available. The prices for a private IP VPN connection are the same as for a regular site-to-site VPN connection.

How AWS works

AWS is isolated into various administrations; each can be arranged in various ways in light of the client's requirements.

Clients ought to have the option to see design choices and individual server maps for an AWS administration.

In excess of 100 administrations contain the Amazon Web Services portfolio, including those for register, data sets, framework the board, application advancement and security. These administrations, by classification, include:

Compute
Storage databases
Data management
Migration
Hybrid cloud
Networking
Development tools
Management
Monitoring
Security
Governance
Big data management
Analytics
Artificial intelligence (AI)
Mobile development

Amazon Web Services

Pritesh Bhoi — Tue, 21 Jun 2022 04:11:56 +0000

In 2002, Amazon launched Amazon Web Services (AWS), which provides programmatic access to hidden features on its website.

In November 2005, Amazon began testing Amazon Mechanical Turk, an application programming interface (API) that allows programs to send tasks to human processors.

In March 2006, Amazon launched an online storage service called Amazon Simple Storage Service (Amazon S3).

An unlimited number of data objects ranging in size from 1 byte to 5 terabytes can be stored on the S3 and delivered via HTTP or BitTorrent. The service pays a monthly fee for stored and transmitted data.
In 2006, Amazon introduced the Amazon Simple Queue Service (Amazon SQS), a distributed queuing service and product wiki (later incorporated into Amapedia), and discussion forums for some products using guidelines that follow the standard. message board convention.

What is Amazon EKS?

Pritesh Bhoi — Fri, 17 Jun 2022 05:15:13 +0000

Amazon Elastic Kubernetes Service (Amazon EKS) is a controlled carrier that you may use to run Kubernetes on AWS without having to install, operate, and preserve your very own Kubernetes manipulate aircraft or nodes. Kubernetes is an open-supply gadget for automating the deployment, scaling, and control of containerized applications.

Runs and scales the Kubernetes manage aircraft throughout more than one AWS Availability Zones to make certain excessive availability.
Automatically scales manage aircraft times primarily based totally on load, detects and replaces dangerous manage aircraft times, and it gives computerized model updates and patching for them.
