  Docker container command Tips & Tricks Here my idea is to use the Unix/Linux 'alias' command for most those common docker container,   network, volume sub- commands to form as shorten to give you more productivity while working on developing the docker images and playing around the newly constructing containers. This trick work on bash, zsh shells. Improve Productivity with smart work alias for Docker commands   First examine the docker container listing with the powerful option '--format' docker container ps -s \ --format "table {{.Names}}\t{{.Image}}\t{{.Status}}\t{{.Size}}" docker ps command To get the logs of any applications that runs in containers we can use the following: alias dkrlogs='docker logs' alias dkrlogsf='docker logs -f ' docker logs with alias trick List of the images alias dkri='docker image ls' docker image list alias trick The container list alias dkrcs='docker container ls' d...

Hey DevOps, DevSecOps Engineers, SRE new bees here I am going to share the Learnings which I've executed every day found that this the best and new tip to improve the performance of ansible playbook executions sorted out and listed here. Planning and designing automation with Ansible Most common DevOps tool used for Planning and Designing is Confluence page Design document must contain a  clear " Objective " - where you will be describe why you wish to do automation on what area Tracking purpose always use a ticketing tool entry preferred tool Jira The design can be breakdown into two levels High level design where we will detail about what each task need to be covered Low level design where we discuss in-depth ideology on each task along with the possible constraints   Usage of global variables (AWX UI use extra vars, host_vars, group_vars etc) discuss their necessity AWX/Tower Job template construct possible options as input to handle overall objective, if...

Hey, hello, dear DevOps, DevSecOps, and SRE team heroes!! Here I came across a new challenge to solve the common problem on Git. You may be using GitHub or GitLab or even Bitbucket for source code management. Now, a few projects, websites, or mobile apps require storing images, audio files, or video files that are larger in size. During the transfer to the client systems, they are facing the following issues: Slowness in git clone and fetch operations: files taking too long to upload or download, leading to delays in deployment and user experience Sluggish commits and status checks: some clients are encountering errors related to file size limitations, causing frustration and hindering workflow efficiency Repository size bloat Complexity in managing multiple branches It's crucial for us to explore solutions that can streamline this process and ensure smooth handling of large sized media files. Git LFS installation on Ubuntu Using the package manager command we can ...

Git installation on Ubuntu is pretty simple. If you are looking for git instatlling on the RHEL or Rocky or Oracle Linux you can use this link . Now most of the software projects are using Git. So let's do installation on Ubuntu wit the following steps: Check for Git exists Install Git Confirm Git Installation Pre-requisites: Pick an instance on Cloud or online terminal of Ubuntu 20+ version to this experiment. Here I'm using the KillerCoda provided Ubuntu. Check for Git exists This is a common requirement when you join a new project and on the Linux machine you would like to know git installed or not. We have couple of options to check it. Let's do it here: dpkg -l git #or dpkg --list git In the output first 'ii' in the list means (if there are packages installed, you should see this mark) that the package is correctly installed and available. alternatively you can also try other option to check git installation on Ubuntu. apt list g...

Hey Guys!! I'm back with a new learning this week, I worked and experimented on Apache Cassandra Distributed database. It's special feature is it's quering capability with NoSQL - Not only SQL. Let's jump to our last set blog post where we have learnt about the Cassandra installation on a VM. Hope you are ready with Cassandra DB node. 1: Optimizing Data Modeling Objective: Understand partitioning and primary key design to optimize performance. Create an inefficient table within company_db keyspace: CREATE KEYSPACE company_db WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1}; USE company_db; CREATE TABLE company_db.employees_bad ( id UUID PRIMARY KEY, name TEXT, department TEXT, age INT, city TEXT ); Now let's Insert some sample records into the table and try to query it. INSERT INTO employees_bad (id, name, department, age, city) VALUES (uuid(), 'Reemi', 'Engineering', 30, 'New York...
