These can then be conveniently run on an intel Nuc or a Synology disk station in the Homelab. https://www.christian-knedel.de/en/post/2021/april/20210411-docker-prestashop/ Sun, 11 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210411-docker-prestashop/ PrestaShop is a European open source e-commerce platform with, by its own admission, currently over 300,000 installations. Today I am installing this PHP software on my server. Some Linux, Docker and Docker Compose knowledge is required for this tutorial. Step 1: Install PrestaShop I create a new directory called “prestashop” on my server: x – + Terminal $ mkdir prestashop $ cd prestashop After that I go to the prestashop directory and create new file called “prestashop. https://www.christian-knedel.de/en/post/2021/april/20210411-esxi-mount/ Sun, 11 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210411-esxi-mount/ Step 1: Enable “NFS” service The first thing to do is to enable the “NFS” service on the Diskstation. To do this, I go to the “Control Panel” > “File Services” setting and click on “Enable NFS”. Then I click on “Shared folder” and select a directory. Step 2: Mount directories in ESXi In ESXi I click on “Storage” > “New Datastore” and enter my data there. https://www.christian-knedel.de/en/post/2021/april/20210405-docker-peertube/ Mon, 05 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210405-docker-peertube/ With Peertube you can create your own video portal. Today I show how I installed Peertube on my Synology Diskstation. Step 1: Prepare Synology The first thing to do is to enable SSH login on Diskstation. To do this, go to the “Control Panel” > “Terminal After that you can log in via “SSH”, the specified port and the administrator password. I log in via Terminal, winSCP or Putty and leave this console open for later. https://www.christian-knedel.de/en/post/2021/april/20210404-xdotools-xclip/ Sun, 04 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210404-xdotools-xclip/ In this tutorial I show how to control a Linux - desktop via Bash. The following packages are needed for the bash robot: x – + Terminal $ apt-get install xdotool xclip After that you can use all xdotool commands, for example: #!/bin/bash #mouse bewegen xdotool mousemove 100 200 #Mouse - Koordinaten erfassen xdotool getmouselocation #Mouse-klick xdotool click 1 Mouse-Klick auf Koordinaten xdotool mousemove 100 200 click 1 #usw. https://www.christian-knedel.de/en/post/2021/april/20210404-docker-jenkins/ Sun, 04 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210404-docker-jenkins/ This tutorial builds on the previous knowledge of “Great things with containers: running Jenkins on the Synology DS”. If you already have LDAP at the start, you only have to create a suitable application group: After that you need to enter the settings in Jenkins. I click on “Manage Jenkins” > “Configure Global Security”. Important: For self-signed certificates, the truststore must be provided by the Java-Opts from the Jenkins server. https://www.christian-knedel.de/en/post/2021/april/20210403-flyer-design/ Sat, 03 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210403-flyer-design/ The Corona crisis is hitting restaurateurs and caterers in Germany hard. Digital tools and solutions can help to get through the Corona pandemic as safely as possible.In this tutorial series “Creative from the crisis” I show technologies or tools that can be useful for small businesses. Today I’m creating a weekly menu for the “OUT OF HOUSE BUSINESS.” You can find many menu templates at https://www.365layouts.com/de/vorlagen/menu/. You can also customize these templates instantly in 365Layouts editor. https://www.christian-knedel.de/en/post/2021/april/20210402-nginx-reverse-proxy/ Fri, 02 Apr 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210402-nginx-reverse-proxy/ As a Synology Diskstation user, I run many services on my Homelab network. I deploy software in Gitlab, document knowledge in Confluence and read technical references via the Calibre web server. All network services communicate encrypted and are secured via a central user management.Today I show how I secured my Calibre service with SSL encryption, access logging and LDAP access restriction. This tutorial requires prior knowledge from “Cool stuff with Atlassian: Use all Atlassian tools with LDAP” and “Great things with containers: Running Calibre with Docker Compose”. https://www.christian-knedel.de/en/post/2021/march/20210321-atlassian-ldap/ Wed, 24 Mar 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/march/20210321-atlassian-ldap/ You can consider yourself lucky if you have your own Atlassian installation. Today I show how I connected Jira, Bamboo and Confluence to my LDAP server. Step 1: Install OpenLDAP I have OpenLDAP set up on my Synology NAS using this Docker compose file. ersion: '2' services: openldap: restart: always image: osixia/openldap container_name: openldap environment: LDAP_TLS: 'true' LDAP_TLS_CRT_FILENAME: '....pem' LDAP_TLS_KEY_FILENAME: '......pem' LDAP_TLS_CA_CRT_FILENAME: '......pem' LDAP_ORGANISATION: "365Layouts" LDAP_DOMAIN: "homelab.local" LDAP_BASE_DN: "dc=homelab,dc=local" LDAP_ADMIN_PASSWORD: ". https://www.christian-knedel.de/en/post/2021/march/20210324-gitlab-setup/ Wed, 24 Mar 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/march/20210324-gitlab-setup/ After my first tutorial about “Gitlab on Synology Diskstation”, I was asked several times if I still use this solution. Nope! In the meantime I have moved my Atlassian tools and the following GitLab installation to an intel NUC. Enclosed I show once my current Compose -file, which can of course also be run on a Synology diskstation.You can clearly see that I now use special setting for OpenLDAP, container registry, mail, certificates and logging. https://www.christian-knedel.de/en/post/2021/march/20210321-atlassian-bamboo-jmeter/ Sun, 21 Mar 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/march/20210321-atlassian-bamboo-jmeter/ Today I am creating a jMeter test in Bamboo. Of course, you can also implement this test setup with Gitlab runners or Jenkins slaves. Step 1: Create jMeter test The first thing to do, of course, is to create a jMeter test. I downloaded jMeter from the following url https://jmeter.apache.org/ and started it with this command: x – + Terminal $ java -jar bin/ApacheJMeter.jar See:My demo test for this tutorial is intended to contain buggy and working samplers. https://www.christian-knedel.de/en/post/2021/march/20210321-docker-jenkins/ Sun, 21 Mar 2021 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/march/20210321-docker-jenkins/ Step 1: Prepare Synology The first thing to do is to enable SSH login on Diskstation. To do this, go to the “Control Panel” > “Terminal After that you can log in via “SSH”, the specified port and the administrator password (Windows users take Putty or WinSCP).

Often, the TV operating systems contain serious gaps or are not kept up to date. A good solution can be a standalone MediaPC operating system. LibreElec runs on the weakest Raspberry and can be controlled with the TV’s remote. LibreElec is more customizable than a SmartTv operating system and offers a variety of apps/modules. All you need is a RaspberryZeroW and a blank SD card. https://www.christian-knedel.de/en/post/2019/july/20190717-gitlab-on-synology/ Wed, 17 Jul 2019 00:00:00 +0000 https://www.christian-knedel.de/en/post/2019/july/20190717-gitlab-on-synology/ Here I show how I installed Gitlab and a Gitlab runner on my Synology nas. First, you need to install the GitLab application as a Synology package. Search for “Gitlab” in the “Package Center” and click “Install”. The service listens on port “30000” for me. If everything worked, I call my gitlab with http://SynologyHostName:30000 and see this picture: At the first login I am asked for the future “admin” password. https://www.christian-knedel.de/en/post/2019/july/20190717-synology-gitlab-runner/ Wed, 17 Jul 2019 00:00:00 +0000 https://www.christian-knedel.de/en/post/2019/july/20190717-synology-gitlab-runner/ How do I install a Gitlab runner as a Docker container on my Synology NAS? Step 1: Find Docker image I click on the “Registration” tab in the Synology Docker window and search for Gitlab. I select the Docker image “gitlab/gitlab-runner” and then select the tag “bleeding”. Step 2: Put image/image into operation: Hosts problem My synology-gitlab-insterlation always identifies itself by hostname only. Since I took the original synology-gitlab-package from the package-center, this behavior cannot be changed afterwards. https://www.christian-knedel.de/en/post/2021/april/20210402-bamboo-monitor/ Mon, 01 Jan 0001 00:00:00 +0000 https://www.christian-knedel.de/en/post/2021/april/20210402-bamboo-monitor/ How to create a build monitor for Bamboo, Jenkins or Gitlab? I’ll figure it out by tonight! I have already written a similar Tutorial for Gitlab Issue Boards. The basis for this tutorial is the Raspberry imager and the “Raspberry Pi OS Lite” operating system. After the OS installation, the SD card can be inserted into the Raspberry. In my case this is a Raspberry Pi Zero. Step 1: Install Matchbox/Window Manager To run a Raspberry in kiosk mode, a window manager and a browser are needed.
