+# This Dockerfile defines the following targets for building an fcli fcli Docker image:
+# - fcli-alpine
+# - fcli-ubi9
+# - fcli-scratch
+# You can select between these variants by passing the --target option to the 'docker build'
+# command, for example 'docker build . --target fcli-alpine'. If no target is specified, all
+# targets may be built but the final image will correspond to the fcli-scratch target.
+#
+# In general, the fcli-scratch image is preferred to avoid having to deal with any CVEs reported
+# on the base images, and potentially having to provide refreshed images for older fcli versions
+# to fix such CVEs. Potentially, we could add commands to upgrade all base OS packages to reduce
+# the number of CVEs on those packages, in case the base image doesn't include those upgraded
+# packages yet.
+#
+# For now, we're only automatically publishing the fcli-scratch image for the reasons above; if
+# there's any demand, we can also publish ubi9, alpine and/or other (like busybox) images that 
+# include a shell. Primary advantage is that this would allow for running a sequence of fcli 
+# commands in a single container invocation (potentially removing the need to mount the data 
+# directory to a persistent volume/host directory, as fcli state will be stored inside the container 
+# for as long the container is alive). Primary disadvantage is that users might expect to be able to 
+# run something like the following:
+#   fcli tool sc-client install
+#   scancentral package ...
+#   submit scan request, ...
+# However, these images don't include Java (required to run ScanCentral Client) nor any other
+# build tools (which may be required by ScanCentral Client to properly package application source
+# code). Users would need to build a custom image that includes fcli and any other tools required
+# for building/packaging an application, or alternatively any of the fcli Docker images can be
+# used to install ScanCentral Client on the host system (using proper volume mappings), from
+# where it can be run with (presumably) all relevant build tools and Java being available.
+# 
+# Before running the 'docker build' command, the fcli executable to be included in the image
+# must be copied into the same directory as this Dockerfile. The fcli build process will 
+# automatically take care of this when releasing a new fcli version. For manual testing of
+# this Dockerfile, you can safely copy fcli 2.5.4 or above into your workspace; the .gitignore
+# file will have git operations ignore the fcli executable.
+#
+# All of the targets defined below have more or less the same structure:
+# - Add fcli user to /etc/passwd
+# - Add fcli executable to the image
+# - Add /data (and /tmp for fcli-scratch) directories with 777 permissions to the image
+# - Set WORKDIR to /data
+# - Set FCLI_USER_HOME to /data
+# - Set container user to fcli user
+# - Define an appropriate entrypoint (fcli for fcli-scratch, shell for others)
+#
+# Regarding FCLI_USER_HOME, fcli uses user.home by default, but if the Docker container is being
+# run as a different user through 'docker run -u <UID>:<GID>', user.home returns a directory 
+# containing a '?' to represent unknown user name for the given UID, which causes issues. Fcli
+# versions 2.5.4 and up allow for overriding user.home through FCLI_USER_HOME.

+# This Dockerfile allows for building a Windows-based fcli image. Although functional, for now

+# the same issues regarding base OS CVEs and ability run run ScanCentral Client as detailed in 
+# the Linux Dockerfile.
+#
+# Some questions to be answered (also see more detailed comments on the actual Dockerfile instructions):
+# - What base image to use for the final image; nanoserver, servercore, ...?
+# - Any improvements necessary for VC++ redistributables installation?
+# - Should container run as ContainerUser, or should we create fcli user like for the Linux images?
+# - Should we have fcli.exe or CMD.exe as entry point (or both)?
+# 
+# Before running the 'docker build' command, the fcli Windows executable to be included in the
