You may want to move your data from a server to another for any reason. Migrating between VPS providers can seem like a daunting task. Like DigitalOcean, other VPS providers, such as Linode and Rackspace, provide root access. This allows you to transfer all of the necessary files to your new DigitalOcean VPS. For this guide, we will demonstrate how to transfer a simple WordPress blog from Linode to a DigitalOcean cloud server.

Running your database inside a container is a very portable solution. It is also reproductible. But how do you manage the data inside that container? With my mysql server running in a docker container, I wanted to connect to it and manage it. The purpose of this tutorial is to share with you how to do it.

One of the priorities of a system administrator is the performance optimization of the deployments and the underlying infrastructure. I have a deployed and running mariadb on a linux server. It is optimized for performance and database storage. Now I am planning deploying a dolibarr docker container on top of it. How can I connect from the dolibarr docker container to the local mariadb database?

This also makes it a great tool to see what is happening in a container instead of having to use the –format specifier which I can never remember how to use exactly

I have previously shared a short [[2020-08-13-work-with-kubernetes-with-minikube tutorial on Minikube]], and while I was using it, I thought I would reuse my local images directly, without uploading and then downloading them again.

There are several APIs in Kubernetes. A ConfigMap is one of these. It is an object which helps to storing some non-confidential data. The data is in the form of key-value pairs. Some use envrionment variables. In this blog post, we will see how you can show multi-value lines. Working with Kubernetes Helm, I went to the documentation.
