- Alpine seems to still be having issues with DNS resolutions inside an LCOW environment. In an effort to reduce these transient problems, switch the base container to a non-Alpine platform. A ticket has been filed with a repro for Alpine DNS issues under LCOW moby/libnetwork#2371 - While this may increase the image size by about 100MB, the goal here is reliability and robustness for the builder container: clojure:lein-alpine was about 142MB clojure:openjdk-8-lein is about 507MB for the target container: openjdk:8-jre-alpine was about 85MB openjdk:8-buster-slim is about 184MB - Ubuntu 18.04 shares a lineage with debian buster, which should be a well supported platform for PDB All OpenJDK container variants are listed at: https://github.com/docker-library/docs/blob/master/openjdk/README.md#supported-tags-and-respective-dockerfile-links

- When the base container image was changed from Alpine Linux to Debian Slim Buster in puppetlabs#3040, the /bin/sh implementation changed. 3c876e5 merged this code On Alpine, /bin/sh is the standard bare-bones cross-platform Bourne Shell. On Debian, /bin/sh is a symlink to dash. - Update shellscript syntax to be compatible with Dash.

Alpine seems to still be having issues with DNS resolutions inside
an LCOW environment. In an effort to reduce these transient
problems, switch the base container to a non-Alpine platform.
A ticket has been filed with a repro for Alpine DNS issues under LCOW
LCOW: Intermittent DNS resolution failures with Alpine containers moby/libnetwork#2371
While this may increase the image size by about 100MB, the goal here
is reliability and robustness
for the builder container:
clojure:lein-alpine was about 142MB
clojure:openjdk-8-lein is about 507MB
for the target container:
openjdk:8-jre-alpine was about 85MB
openjdk:8-buster-slim is about 184MB
Ubuntu 18.04 shares a lineage with debian buster, which should
be a well supported platform for PDB
