To connect with Amazon AWS you need to use a key. Usually that key is protected with a password. Because it is not possible to use Ansible with a password protected key some configuration is necessary.Continue Reading
Installed a first Kubernetes cluster consisting of 1 master node and 1 worker node on CentOS 7. Kubernetes has version 1.6.2.
Kubernetes is not working with CentOS 8 yet so I have used the latest CentOS 7. Everything is installed on Oracle VM VirtualBox on a Windows 10 host.Continue Reading
The idea is to fully script the creation of a WordPress server including the database on CentOS 8 and Amazon Web Services. For this Ansible will be used. I will describe this in several steps/posts.
Step 1 Create the Linux server
Step 1 is to create the Linux server from a bastion host within AWS. For now we will use CentOS 7 because CentOS 8 is not availabe. Later it will be changed for CentOS 8.
To get some hands on experience with OpenShift I have installed OpenShift 4.1 on AWS using the defaults.Continue Reading
In order to gain some knowledge about Grafana, InfluxDB and Telegraf I did a basic installation. Grafana and InfluxDB were installed on a CentOS 7 server. The Telegraf agent was installed on a separate CentOS 7 server (which also hosts petersplanet.nl by the way).
Although I had setup a daily cronjob for the certbot renew command it appeared that the automatic renewal did not work. It only worked interactively as root.
I have created an Ansible script to automatically update WordPress on a server. In this case the Ansible script runs locally on that server.
A few years ago I bought a Raspberry Pi but I never found time to experiment with the GPIO bus.
If you buy cycling tyres with a width 25 mm this does not automatically mean they are exactly 25 mm or 25,4 mm (1 inch).
If you want to experiment with servers and applications you will probably need your own test lab with virtual machines. The point is that you don’t want your test lab to interfere with your home network. This can be easily realised with Oracle VirtualBox and a network address translation network (NATNetwork) on a workstation.
