Keycloak and Nextcloud are both popular open source software. The first is an identity provider and broker, the second one is collaboration platform. Instead of having multiple accounts on several online platforms, you want to have one identity and log into multiple platforms. This is the job of the OpenID Connect protocol and is supported by Keycloak. In this guide I walk you through the steps of connecting Nextcloud with Keycloak to support a seamless single sign-on experience.
The public perception of success seems very wrong to me. if media and the public discuss the success it is often referred to an individual that single-handedly built a fortune. “He/She is a successful person, because he/she funded a successful company”. Wealth and power are the keys to success and being an outstanding person. Seeking power and wealth is part of the human nature.
When you work on multiple projects with different tech (Docker, npm, python, ..), a common interface to build, start, install or clean the state of the project is a powerful tool. There are various task runners for this job, however, every one of them requires you to install at least one dependency and so must everybody else who wants to use the project. What if we can use a task runner that is preinstalled on every computer? What about bash/zsh?
Nobody wants to be notified by email anymore, especially if its a failed cron job. We have advanced monitoring systems that tell if somethings wrong. In my case I use Grafana and Prometheus and Node exporter to collect host metric, visualize them and send out alerts. Usually, one would set up an exporter to monitor an new piece of software, but for cron there isn’t any exporter available. In contraire there are a lot of online service to monitor your cron jobs, such as Cronitor.io. But we do not want to add another dependency for simply monitoring cron jobs.
You can easily batch resize groups of images within Mac OS by using the included Preview app, that is, taking a group of pictures set at one or various resolutions, and collectively resize them all together in a group to a new resolution.
Wiki-Links[[ ]] are not part of the markdown specification, but are often used by markdown editors such as Obsidian. As they are not supported by most markdown converters we need to convert the wiki links on our own.
In this tutorial I am going to show how you can connect a Garafana container that is hidden behind proxy with Keycloak. We want to log into Grafana with a Keycloak user and experience a seamless SSO-flow. Therefore we are going to configure an OAuth client for Grafana.
The official Docker documentation has section about container backup. This section tells you how to backup an attached volume and the command to do so is pretty elaborate. For automating backups you don’t want to script parametrized commands such as this one. A simple script will do the job.
Open Source Software (OSS) is free to access. Everybody can download the code, change it and build something new. This requires expertise. Expertise that is hard to find on the market. Therefore open source software is not free.
