Today we are going to deep dive into that jenkins is and how it improves your devops continuous integration environments. We are going to cover what life is like before using jenkins and the issues that jenkins specifically addresses. Then we will get into what jenkins is about and how it applies to continuous integration and the other continuous integration tools that you need in your devops team.
If you are familiar with Jenkins, you would usually create new jobs or builds and configure them. Basically what Jenkins file is that instead of you creating and configuring jobs on the Jenkins user interface you would write a file or you would script that build and it's configuration in a file.
In this post we are going to see the docker exec and how we use it. Then we are going to see is docker attach and how we use it. So what is docker attach and how is it different from docker exec.
Email validation is a very debatted question. The one we are going to see in this post will probably not catch every single email. There’s a lot of debate for what is the best regular expression for an email and I’ve done a fairly simple one here it captures a most of them to be honest in my opinion but it’s maybe not the perfect one.
How do I run a docker container with a specific user. You connect to the terminal as root user, but I would like to connect as a different user. How can you achieve that ? The solution is to add a user flag to your command line when you start the container or in your docker compose.
In my daily work, I have utility containers. Some are based on ubuntu, others just on busy box. I start them, run few commands and destroy them. For some specific task I need a long running container and populate it with files that are from the host. And after my work is done, I copy the result from the container back to the host.
Apache groovy is an object-oriented programming language used for the jvm platform. This dynamic language has a lot of features drawing inspiration from python small talk and ruby. It can be used to orchestrate your pipeline in jenkins and it can glue different languages together, meaning that teams in your project can be contributing in different languages.

I am moving my configuration from a windows machine into an Amazon AWS EC2 instances which runs Linux.
I have successfully installed and made to work an Hudson installation on Windows machine. Now I am trying to move my installation to a Linux server. When I perform the installation and run it, gives me an error. Here is how I fixed it.
We're on a clean docker install on Linux all the networks we saw came as part of that default install so this bridge network was created for us. It contains a single virtual switch called docker0. We said this is the default Network and switch meaning if we create new containers and don't specify a network for them to join they're gonna get connected to that docker0 switch, be part of this bridge network and because the bridge network is created with the bridge driver it's a single host network.
![[SOLVED] Laravel docker /usr/sbin/apache2ctl,: not found exited with code 127](https://res.cloudinary.com/brightsoftwares/image/upload/t_BSBlogImage/f_auto/q_auto/dpr_auto/v1653595902/daniel-jensen-UDleHDOhBZ8-unsplash_prytio.jpg)
I recently finished a Laravel project and I steped one more step to package it in docker. In the process I encountered a strange behaviour. The docker-compose tool threw this error /usr/sbin/apache2ctl,: not found exited with code 127 at me. I finally managed to solve it. Here is how.
![[SOLVED] Could not open input file: artisan in Laravel using docker image](https://res.cloudinary.com/brightsoftwares/image/upload/t_BSBlogImage/f_auto/q_auto/dpr_auto/v1653589966/pexels-greta-hoffman-7859013_qwwcme.jpg)
When I run my laravel application, I get the error Laravel docker image Could not open input file: artisan. I finally found the root cause of the issue, let me share it with you. I generated my application in Laravel sail but now I am working to make it run inside a docker container. My application runs well in I use the docker-compose run but during the docker build process to generate the image, I get an error.
Laravel is a very useful PHP framework to build awesome projets. It has interesting tools that allow a developper to quickly release a prototype of his/her application. I am a fan of organizing my application inside containers for easy deployment and dependencies management. I came accross an interesting project I wanted to deploy and test. I though I would share with you the steps to perform such a deployment. Let's get started.
