To login to the Kubernetes dashboard, you need a token. This token can be retrieved with the following command: kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep <admin-user> | awk '{print $1}')
I have many private git repos to manage all the configuration files, ansible playbooks, source code and other stuff you would want to version. Most of them are just for me to view and often I want to quickly ‘save’ my current process by creating a commit I can go back to. I just recently switched to zsh after years of using bash – never had I thought that my life would change that much. So many neat little things that are really helpful and make my life easier. Themes, plugins and the oh so amazing oh-my-zsh really make it a pleasure to do stuff on the console. (I always have to bite my tongue once I SSH into a server that only has sh or bash now. ...
I finally wanted to setup my own kubernetes cluster as everyone I talk to, said its the hottest shit. I’m using three VMs, hosted at Netcup running the latest Debian 9 Stretch build. I’ve installed most basic tools for me and also already set up docker using this amazing ansible role. Make sure to disable any swap you have configured – kubelet will not start otherwise. The documentation on how to install things is pretty good, but I’ve missed some details, that I banged my head on, so I will copy most snippets over for future reference. Keep in mind, that this might have already changed and is no longer working at the time you read this. ...
Usually I love to use guake as my terminal in gnome, as it quickly hides using the F12 key and you always have your terminal in reach. When doing more server heavy tasks, I often end up having several tabs in guake which tends to be messy. In those cases I love to use Terminator – the ultimate Terminal. Quickly installed using the following: # Debian / Ubuntu apt install terminator # Arch Linux pacman -S terminator Then you can use the following keyboard shortcuts to easily spawn new terminals the GUI way, instead of using tmux. ...
I’ve been using Arch on my XPS 2015 edition since the very beginning. Not only was the support of the software components newer/better than Dell’s official Ubuntu version for the developer edition, but also I absolutely love the rolling release before it was cool. So as we are bleeding edge, sometimes things break. Arch moved over to wayland some time ago, but like two days ago my touchpad’s right & middle click stopped working. Quick google search later revealed, that my gnome settings had the following option set to ‘fingers’. That didn’t work as my XPS has ‘areas’ – so switching it over with this simple command, fixed things for me. ...
The default way to copy your ssh key(s) to a remote server is to use the _ssh-copy-id _command. This will create a secure connection to the remote server over SSH and then check if the user exists, create the folder&files if needed and add your keys. Works, Easy, Simple. My problem is, that often I’m already in the shell and I logged in with some password combination, that I would need to enter a second time to copy my ids. Also I don’t always have all my keys on one machine. As I often get asked by my colleagues, what my SSH keys are, there is a nifty trick you can do, instead of sending them over via E-Mail. ...
