[dba-Tech] Building Containers

[Jim Lawrence]

Hi All:

I am still working to get myself up to speed in the building of Containers. After working so many years with VDs, where the installation process was obvious, Containers still leave me challenged...there is just so many items that must be handled when building a distributive container.

One interesting thing is the OS that a Container uses. It has to be super small, full featured and in the case of IoT (Internet of Things) applications, it must be very secure. To that end check out the Linux distro Alpine at https://alpinelinux.org.

If it is run "headless" and stripped, a fully functional Alpine OS can be squeezed to only into only 3MB. (Of course this is huge compared to our systems back in the 80's but by today's standards, where an OS can top 20GB...)
