Optimising Docker Image Sizes: “Self-extracting” Node.js Applications

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.As a follow-up on last week's article on tools for inspecting Docker images, and Docker image sizes in particular, today I'd like to introduce another - more custom - approach for reducing the size of Docker images for production deployments. As a means of shaving off an additional 50 MB from the packaged application in question I came up with an idea somewhat reminiscent of the self-extracting archives of yore (of the WinRAR and ...

Tools for Inspecting Docker Images

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.Recently, I needed to inspect a Docker image in order to optimize its size for distribution and deployment on an ARM-based industrial microcontroller with rather tight bandwidth constraints. Once deployed at customer sites, these controllers typically don't have an Internet connection but still need to be updated occasionally, via the local network in that case. Since there's no guaranteed minimum network speed in this type of environment, yet software updates still have to complete ...

Cloudcraft – Cloud Architecture Diagrams and Visualisations

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.After recently having written about AWS cloud visualisation and management tools such as CloudMapper and Vantage I was made aware of yet another such tool by Sebastian Reuße: Cloudcraft allows you to not only visualise your AWS cloud architecture with beautiful as well as somewhat playful isometric infrastructure diagrams reminiscent of turn-based strategy games but also provides live connectivity with your actual AWS infrastructure and so-called "smart" components. Using these features you don't have to ...

Vantage – A Unified AWS Console

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.In last week's blog post I casually mentioned that out-of-the-box with AWS there's no single unified console providing you with an overview of your deployed infrastructure. Thankfully, there's Vantage - a centralized dashboard that provides you with such an overview and cost transparency across AWS regions and accounts through views, global search, and actionable insights. Up to $500 in monthly AWS spend Vantage is free. Beyond that there are Pro and Business plans at a ...

CloudMapper: An AWS Visualisation Tool

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.CloudMapper is an AWS visualisation tool that's highly useful for getting an overview of your AWS infrastructure and network setup. Depending on the number of services, instances, VPCs, and subnets used, getting lost is quite easy, especially when considering that out-of-the-box with AWS there's no single unified console from which to get an overview of your deployed resources but rather a multitude of consoles, one for each AWS service. Therefore, keeping track of your infrastructure ...
