DevOps Toolchain Enhancement

Historically, our company ubitec had started with a customer project. Agile/Scrum was our proposal for working with customers. Time by time, Agile/Scrum also became our culture for software development.

To be successful with this development approach, we somehow needed to have a fast release for customers (i.e. every one week). Back then, we had a build tool Jenkins which was responsible for having sprint release packages for our customers. The build job pipelines contain some steps such as gathering the artifacts, checking the code convention, running the tests, building docker images, and packaging an archived file (a zip file).

The set of tools involved in a pipeline is roughly called a toolchain. It is just a part of a bigger process called the DevOps toolchain.

DevOps is a proven method that fits Agile. Today, it is even treated as a mandatory factor to have Agile succeed. Therefore, DevOps toolchain enhancement is a critical task.

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent"> <div id="child"> </div> </div> And, CSS: #parent{ position: relative; overflow:hidden; } #child{ position: absolute; top: -1; right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-positi...

BIRT - Fix the size of an image

I use a dynamic image as a logo my report in pdf. At the beginning, I use table to align the logo in left or right. I meet a problem with some images with a large width or height. My customer requires that the logo should be displayed in original size. These following steps solves my problem: 1. Use Grid instead of Table 2. Set Grid "Height" is 100% and "Width" is blank 3. Set "Fit to container" for images are "true". Download the the template here .

From JSP to AngularJS

Our team maintained a project that was used a quite old web technology JSP . Our project likes a web portal that can contain some other smaller projects, I called it a module. Now, our customers want to add a new module into it. We met a problem is the current projects can't be testable and hard to maintain because both the logic and GUI are mixed together by using JSP and JSTL. It was really a messy project structure. Therefore, we didn't want to continue this approach. Testing is very important, as well as a good structure for maintenance. We would like to apply MVC pattern for testable and maintainable ability purpose. Yeah, that was actually time for changes. Our project structure can't be testable and has poor structure. We listed out some options: Refactoring all current modules -- terrible approach, too much efforts, too risky due to a lot of modules. Using MVC just for the new modules with Servlet for C ontroller, Java class for M odel and JSP for V i...

DevOps for Dummies

Everyone talks about it, but not everyone knows what it is. Why DevOps? In general, whenever an organization adopts any new technology, methodology, or approach, that adoption has to be driven by a business need. Any kind of system that need rapid delivery of innovation requires DevOps (development and operations). Why? DevOps requires mechanisms to get fast feedback from all the stakeholders in the software application that's being delivered. DevOps approaches to reduce waste and rework and to shift resources to higher-value activities. DevOps aims to deliver value (of organization or project) faster and more efficiently. DevOps Capabilities The capabilities that make up DevOps are a broad set that span the software delivery life cycle. The following picture is a reference architecture which provides a template of a proven solution by using a set of preferred methods and capabilities. My Remarks Okay, that sounds cool. What does it simply mean, again? The f...

PSMDB - A MongoDB alternative for having Encryption At Rest

Encryption is the most popular tool for securing data both in transit and at rest. - For protecting data in transit, we can configure to use the TLS connection - For protecting data at rest, we can use Percona Server for MongoDB (PSMDB), an open-source alternative for MongoDB Enterprise. License PSMDB Docker images follow the SSPL license. Therefore, it is not a problem when I only have my containers deployed in on-premises environments. Running MongoDB Replication on OpenShift I have successfully installed the replication by following the guide Install Percona Server for MongoDB on OpenShift . In order to make it work properly with my needs, I disabled some features from the default deployment. See the detail in this change Basically, I needed to create a CRD (Custom Resource Definition) to let OpenShift/Kubernetes what PSMDB is. Then, I deployed the Operator pod. Finally, I deployed the PSMDB StatefulSet. I used NFS shares for Persistent Volumes. Create CRD for PSMDB 2 git clone http...
