Containerized Alpine shines in some key areas: While there are some other uses for Alpine, most projects will fall under these two categories. Alpine is arguably the most user-friendly, containerized Linux distro. The result is a compact, single-file executable that contains much of the functionality of a full Linux distro, though many of the functional options available in those full versions have been left out of BusyBox in the name of saved space. Next, youll create a Dockerfile for your statically-compiled BusyBox binary. Although it is Where are Docker images stored on the host machine? Follow these tips to spot Linux admins can use Cockpit to view Linux logs, monitor server performance and manage users. Alpine has also taken a strong stance on security in general.

Creating a BusyBox container using the Docker CLI (enabling us to run common commands). I guess the MIT license is maybe a key factor. 16.04. These components help Alpine Linux function while enabling developer-centric features. Beyond the basic performance benefits, though, there are deployment factors that may argue in favor of RancherOS. Ubuntu has moved into the space once occupied exclusively by Red Hat Linux: its a safe choice for enterprise deployments, with the support and reputation to make its selection one that most executive committees will see as reasonable. Its important to remember, though, that reasonable does not translate to best in every circumstance its still a big, full operating system with all that that implies.
