Helm is extremely useful and efficient when it comes to distributing, installing and upgrading applications hosted in Kubernetes. But sometimes you may have a need to patch an existing release and there is a quick way to do that which I would like to share with you today. A scenario I had to face was that I discovered missing PodDisruptionBudget on one of the production deployments and after this has been fixed in the source code I had therefore a need to add it to the existing Helm release to ensure configuration consistency. ...

So, recently I’ve faced a scenario where I got a chance to dig more into different Kubernetes Service types and experiment with those. I would like to share about one of the experiments where I tested several Kubernetes Service types in order to implement proxying of the requests to external services from Kubernetes cluster. Why would proxying to external services from Kubernetes cluster be relevant? There may be multiple reasons for why you would look into setting up this kind of proxying to external services from Kubernetes cluster. ...

What is static code analysis and why do I need it? Developers are doing an important job - we create programs and systems that make life on this planet easier, better and safer. Ideally. But, how do we actually ensure that the code, that these systems and programs are built upon, is actually secure? Though we're developers we're also humans, and humans make mistakes. Let's say we're developing an online store where users can buy products, pay for them and get them delivered to their doorstep by providing their personal and credit card information. While developing this application we've unintentionally introduced a SQL injection vulnerability which was discovered and exploited by a malicious actor resulting in him/her getting access to application's database and stealing all information about our customers and their credit cards. Well, that sounds pretty scary, don't you think? ...

If you're a .NET developer, I bet that at least once you've experienced errors like "System.IO.FileLoadException: Could not load file or assembly '[ASSEMBLYNAME], Version=x.x.x.x, Culture=neutral, PublicKeyToken=xxxxxx' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)" If you did, welcome to the club! I've been dealing with issues like this for several years now and there are some tools out there that could make this process less painful. Trust me, sometimes it may get pretty painful… ...

There are probably no developers out there (or at least very few) who have never created a console application - use cases where such apps are a first choice are hundreds, if not thousands. In my team we have several administrative tools that are being distributed as console apps in addition to the main application. Multiple stakeholders are using these apps in order to easily perform administrative tasks, make changes to application's metadata, interact with the database, integrate customizations into standard application functionality, etc. ...
