Keeping your system tidy: creating simple packages

Filed under

Installing software on a GNU/Linux system is often as simple as opening a package management interface, selecting with the mouse which packages you want installed, and letting the package management system install the wanted packages—plus, any dependencies required for the package to run. But what can you do if you want to install software which is not already packaged in your distribution of choice, and you still want it to be registered in your package management system for easy maintenance?

Create your own package, of course. Which doesn't have to be all that hard.
As most people know, there are two main package management systems: the Red Hat Package Management system, or RPM, and the packages used for Debian and its derivatives, commonly known as .deb files. Since I'm a Debian developer, my experience with the latter format is obviously quite a bit higher than the experience I have with the RPM format, and so this post will focus on Debian packages; but it should be noted that most of the concepts explained here will apply equally well to self-made RPM packages.

Package management concepts

Before I can go ahead and explain how to create a simple package, it's important to understand a few things about packages and package management systems in general.

OpenStack in the Headlines

  • OpenStack Adoption and Revenues on the Rise
    One thing you can count on at the semiannual OpenStack Summits are new studies and reports about OpenStack. And that's the case at the OpenStack Summit going on in Barcelona, Spain, now through Oct. 28. A number of studies are being discussed at the event, including the October 2016 OpenStack User Survey and new analysis on the state of OpenStack from analyst firm 451 Group. According to the 451 Group, the OpenStack software market will generate $1.8 billion in revenue in 2016 and grow to $5.7 billion by 2020. The firm is forecasting that the five-year compound annual growth rate for OpenStack from 2015 through 2020 will be 35 percent. The semiannual OpenStack User Survey is also a topic of discussion at the OpenStack Summit, providing insight into the state of OpenStack deployment. Among the high-level findings is that 71 percent of OpenStack clouds are now in production and fully operational, up from 59 percent in 2015. Also of note is how well-regarded the Kubernetes orchestration system has become, outpacing CloudFoundry in terms of user interest. In this slide show, eWEEK takes a look at some of the highlights of the latest OpenStack research studies.
  • ​HPE backs off from OpenStack development
    HPE still supports OpenStack in its Helion cloud program, but it's cutting way back on how much it's spending on helping create OpenStack.
  • Is OpenStack Cloud Interoperability a Myth?
    Boris Renski, co-founder of Mirantis, argues that interoperability doesn't start at the infrastructure layer. It starts with applications, he said. BARCELONA—A keynote highlight on Oct. 26 at the OpenStack Summit here was a live, onstage demonstration with 16 OpenStack vendors, all showing a degree of interoperability. The demonstration was part of an interoperability challenge, though, according to Boris Renski, co-founder of Mirantis and member of the OpenStack board of directors, the infrastructure layer is not necessarily the right place to emphasize interoperability.
