Jenkins vs. AWS CodeBuild for building Docker applications

Add SonarQube quality gates to your Jenkins build pipeline
SonarQube is an excellent tool for measuring code quality, using static analysis to find code smells, bugs, vulnerabilities, and poor test coverage. Rather than manually analysing the reports, why not automate the process by integrating SonarQube with your Jenkins continuous integration pipeline? This way, you can configure a quality gate based on your own requirements, […]
Setup Spring Boot behind a load balancer using the X-Forwarded headers

VPCs, subnets, and gateways – fundamentals for working with containers in AWS
Let’s be honest, for most developers getting their software written and working on their own machine and maybe a test environment is the main priority. Deploying to production? Ah, that’s another team. All the AWS network ‘stuff’ – VPCs, subnets, gateways? Someone else’s business, right? Secondary to the contents of the holy Docker image and […]
