This blog post aims to provide an overview about how to setup a decent CI/CD workflow for an android app with the capabilities of Gitlab. The blog post has been written for Gitlab Ultimate. Nevertheless, most features are also available in the free edition.
The goal is mainly to provide an overview about Gitlab’s CI/CD capabilities. It is not object of the blog post to test and/or develop a complex android app, or to handle special edge-cases in android app development.
For all my university software projects, I use the HdM Gitlab instance for version control. But Gitlab offers much more such as easy and good ways to operate a pipeline. In this article, I will show how we can use the CI/CD functionality in a university project to perform automated testing and an automated build process.
Everyone knows the problem of keeping track of expenses. Many applications offer an overview of all expenses, but entering all data individually can be quite time-consuming. To overcome this task, we have developed SWAI, ‘A Scanner with A.I.’.
Some users might have concerns regarding security using GitLab for a variety of purposes, including commercial and business applications. That is, because GitLab is commonly used as a cloud-based service – on someone else’s computer, so to speak. So setting it up for running it on your own server is the conclusion, whether it be a NAS, real dedicated server or even a Raspberry Pi. So, as a side quest, we decided to set things up on a Raspberry Pi Model 3 for comparison. The following part will cover the installation procedure (mostly according to the official GitLab page) as well as hints to some potential pitfalls. Continue reading →
When it comes to software development, chances are high that you’re not doing this on your own. The main reason for this is often that implementing components like UI, frontend, backend, servers and more is just too much to handle for a single person leading to a slow development process. So, you have to team up with others. Therefore some collaboration tools (e.g. SVN, Git) have been established so that you don’t accidentally overwrite someone else’s code and vice versa.
The big challenge with such collaborative projects is to ensure a high quality of the software even with a high level of developer activity. One instrument for this is continuous integration, whereby the individual application components are continuously brought together and successful interaction is ensured.
Especially in large projects high software quality and a structured development process are of enormous importance. That is why we decided to carry out the complete development and quality assurance process from the creation of a project, the definition of tests and continuous integration of the components to the automatic deployment of the application using a small sample project.
The following image shows the architecture of the small node application:
