Modern software is built on top of dozens if not hundreds of dependencies. This help developers to focus on business value instead of reinventing the wheel. But those dependencies must be updated to prevent shipping security vulnerabilities. Renovate scans your source code repository for a wide range of languages and offers updates as merge requests. This post provides an introduction to use Renovate with Docker, containers and container images.

curl is the go-to tool when it comes to talking to API from the console and in shell scripts. But working with the HTTP response code and the body of the response at the same time does not work easily. This post demonstrates how to receive response headers and body at once if the response body contains JSON.
Please note that I made a mistake :-( The parameter --write-out does not print the response header. I corrected the post and published a script to achieve the same.
