Hey everyone 😄 recently I completed a team project regarding set up some CI/CD with Rest API and because it should have CI/CD so we use Jenkins but in here I am going to demonstrate that "How to fetch all repositories of any workspace in bitbucket ". So here, we use bash script and bitbucket rest API  But first, we need to understand curl command. Well according to GfG:- "curl is a command-line tool to transfer data to or from a server, using any of the supported protocols (HTTP, FTP, IMAP, POP3, SCP, SFTP, SMTP, TFTP, TELNET, LDAP or FILE). This tool is preferred for automation since it is designed to work without user interaction. curl can transfer multiple files at once." So hey we know, we need curl for sending/receiving request and response from bitbucket server. The other thing we need is bitbucket APIs which can found in here Bitbucket API . In the website, there are lots of APIs available but we need only this one  {workspace} .  So ...

Configure 5099 rpm packages using Yum Without Internet

-
Image
Hey everyone 😀, Today I want to share an exciting configuration tool which is called YUM "not Yumraj " but RHEL's Yum . Yum is the default package management utility in RHEL/Centos Linux. For your knowledge aptitude (apt) is a  default package manager for Debian GNU/Linux systems. Note :- Without Yum or apt you will face difficulty to manually install the packages in a Linux system. Why we need Yum?  Yum is used to searching, installing, updating and removing necessary rpm files from the system. RHEL/Centos Linux use .rpm file to manage the software. A . rpm file extension represents the Linux software package file. Yum uses a repository to manage the rpm files. A repository is the collection of RPM files. Since Yum depends on the repository, there must be at least one working repository before it can be used. A repository can be configured either locally (on local hard) or remotely (on network or internet). KeyPoints To Remember YUM stands for Yellow Dog Updater Man...

Today, we see how to allow Postgres Database Logical Replication in our local setup using docker-compose.  Environment Setup We have two PostgreSQL instances configured using Docker Compose: Publisher (postgres-1): The source server where changes are captured. Subscriber (postgres-2): The destination server that receives replicated data. Docker Compose Configuration Publisher (docker-compose.yml) version: '3.8' services: postgres-1: build: ./ container_name: postgres-1 environment: POSTGRES_USER: postgresadmin POSTGRES_PASSWORD: admin123 POSTGRES_DB: postgresdb PGDATA: "/data" volumes: - ./postgres-1/pgdata:/data - ./postgres-1/config:/config - ./postgres-1/archive:/mnt/server/archive ports: - "5000:5432" networks: - custom_net...

Regex 101: An Introduction to Regular Expressions for Developers

-
Regular expressions (regex) are a powerful tool for searching and manipulating text. They allow you to describe patterns of characters that you want to match, rather than specifying every possible combination of characters. In this blog, we will go over some common regex operations and provide examples for each one. Matching a literal string: regex: hello will match the string "hello". Matching any character: regex: . will match any single character. Matching a set of characters: regex: [aeiou] will match any single vowel. Matching a range of characters: regex: [a-z] will match any single lowercase letter. Matching a negated set of characters: regex: [^aeiou] will match any single non-vowel character. Matching zero or one occurrence: regex: a? will match either the string "a" or an empty string. Matching zero or more occurrences: regex: a* will match any string that contains zero or more "a" characters. Matching one or more occurrences: regex: a+ will matc...
