At NameHero, we’re big fans of docker, and have multiple docker tutorials to help you get started. However, there can also be too much of a good thing, as it’s very easy to download a docker image and then forget about it after testing it for a while. Because docker images can replicate entire systems […]

We’ve seen the usefulness of docker, and how we can use it to run applications normally requiring huge amounts of configuration such as web servers and databases. This seems like the perfect solution for complex packages that require expert maintenance and setup. And it is! There’s a reason why docker is widely used and loved. […]

Using docker can become addictive. Once you see how easy it is to download and start a container running an application that normally requires heavy configuration – like a web server, for example – you start to think of everything in terms of docker containers. But with this comes risks. Docker containers can grow in […]

In the article on how to fix the Docker “permission denied” error, we saw that we can use docker to easily set up pre-configured instances of applications so that we don’t have to know too much about setting it up and running it ourselves. Long-running applications like database servers and web servers that require complex […]

Docker is a way for developers to package applications with all their dependencies and configurations into a single image that can run on any setup, making it easy to port applications across machines in a consistent manner that removes all complaints such as “it works on my machine”. These images or containers are designed to […]

Docker allows you to create “images” for your application that contain everything needed for the app to run on another machine. The process of creating this image is called “building,” and during this build process, you need to specify all the files and folders required for your application. You can add these in two ways. […]

Docker is a framework for downloading and easily installing applications on your server. If you don’t use Docker and install an application directly on your system, it can change your system files, and you may need to resolve dependencies, among other things. Uninstalling the application can leave stuff on your server as well. But with […]

The “envsubst” tool is part of the GNU’s “gettext” package that programmers use to create multilingual programs. We use envsubst to substitute environment variables in a file or a data stream. This is particularly useful when creating and adapting configuration file templates in a variety of scenarios. For example, you sometimes have a template configuration […]
