Installing Podman and Buildah on Red Hat Enterprise Linux 7įirst, we need to install Podman, which is in the extras repo on Red Hat Enterprise Linux 7. You’ll be able to use systemctl to start and stop the container just as you would for a non-container installation. This article also shows how you can use Buildah to build an image with your completed application that you could use for production.Īdditionally, you’ll set up the Red Hat Enterprise Linux 8 Redis application stream in a container that is managed by systemd. This method isn’t the way you’d want to do things for production, but it gets you started developing quickly and should give you essentially the same development inner loop as you’d have when developing locally without containers. Because it is mapped via a volume mount, the changes you make to the code will be immediately visible from the container, which is convenient for dynamic languages that don’t need to be compiled. You’ll be able to edit the code on your local machine as you would any other application. The code will be stored on your local machine and mapped into the RHEL 8 Node.js container when it runs. In this article, you’ll create a Red Hat Enterprise Linux 8 Node.js container with Buildah, and run it with Podman. You don’t have to worry about conflicting versions. Instead, each container gets an isolated user space. There is no need to use scl commands to manage the selected software versions. While you need to get comfortable with containers, all of the software installs in the locations you’d expect. In this article, I’ll build on that base to show how to get started with Node using the current RHEL 8 application stream versions of Node.js and Redis 5.įrom my perspective, using Red Hat Enterprise Linux 8 application streams in containers is preferable to using software collections on RHEL 7. In my previous article, Run Red Hat Enterprise Linux 8 in a container on RHEL 7, I showed how to start developing with the latest versions of languages, databases, and web servers available with Red Hat Enterprise Linux 8, even if you are still running RHEL 7.
