This blog post dives into setting up the Open Source “S3” compatible object storage server “MinIO” as backend for “restic” backups. The main focus of this setup is to have a stable storage backend with nearly zero maintenance – ok more or less zero maintenance.
One of “Go”’s strengths is its capability to build your “Go” project cross-platform for all kinds of operating systems and architectures, e. g. windows/amd64 (Windows), linux/386 (Linux), darwin/amd64 (MacOS). But setting up the environment for this is not that easy. This article is a small “HOWTO” listing all the steps required to set up a cross-platform “Go” environment.
Occasionally I get some really weird errors when I try to install gems using gem or bundler. It took me some time to find out the reason for this. Read on if you’d like to hear the full story.
It’s quite easy to pull images via docker down to your local developer machine. But sometimes you need to get images onto servers which have no access to the World Wide Web (WWW) nor to an internal docker registry. In this article I show you how to use docker save and docker load to get the required images onto those servers.
… or why you should care about “OOMScoreAdjust” in your systemd-enabled docker-images Recently I put together a docker image with “PostgreSQL 9.4” installed from the project’s software repository on “CentOS 7.1” to back a rails application. Unfortunately I was not abled to run the “PostgreSQL”-server in a container based on that image. It failed with exit code 206/OOM_ADJUST. In this article I’m going to describe the reason for the failure using a minimal failing example.
Given you’re a professional website designer and would like to work on some wonderful project. This project might be about designing a new website with a blog and a shop for one of your favourite customers. To get involved in this project, she asked you to design a mock-up with your ideas first and send it to her. In this article I’m going to show you how you can give away your mock-up in an easy manner without setting up a full-blown web server stack.
I use middleman for my own website. To make it easier for me to pickup my work over different machines , I added a small start script to the repository. In this article I’m going to show you how it works and how you can make use of it for your own website build on top of middleman.
If you need to share files from your local system with others, you’ve got plenty of options. For some of them you need a client installed locally and an account at a remote website. Fortunately there are easier options available as most programming languages come with an HTTP server. In most cases it’s able to serve files from a local directory and is sufficient for a lot use cases. In this article I am going to show you, how I solved the problem by “writing” a local web server in Go running on Linux, Windows and Mac OS X.
You can find quite a few IT infrastructures where an HTTP proxy is used to secure the access to the “World Wide Web” (WWW). In smaller company environments you can configure the proxy for each workstation manually. In larger environments you normally use a so called “proxy.pac” for this. This article gives you an introduction to “proxy.pac”-files.
Recently I faced a rather strange issue with networking and docker: I was neither able to install Rubygems in a container nor access any other services on external IP addresses. In this article I’m going to describe how I solved this issue and what I learned about systemd-networkd.
