# Base docker image with all required dependencies for OB-USP-A
#
# Based on Ubuntu 22.10 (Kinetic Kudu), which provides libmosquitto 2.0.11 and libwebsockets 4.1.6
# This image includes some basic compilation tools (automake, autoconf)
#
# One-liner execution line (straightforward build for OB-USP-A execution):
# > docker build -f Dockerfile -t obuspa:latest .
#
# Multi-stage builds execution lines (to tag build stages):
# 1) Create the build environment image:
# > docker build -f Dockerfile -t obuspa:build-env --target build-env .
# 2) Create the OB-USP-A image, then build the application
# > docker build -f Dockerfile -t obuspa:latest --target runner .
