# Building this Dockerfile executes a full build of the Recovery Tool, cross-compiling inside
|
|
# the container. The resulting executable is copied to the output directory using Docker BuildKit.
|
|
|
|
# You need to pass 3 parameters via --build-arg:
|
|
# 1. `os` : the GOOS env var -- `linux`, `windows` or `darwin`.
|
|
# 2. `arch`: the GOARCH env var -- `386` or `amd64` (note that darwin/386 is not a thing).
|
|
# 3. `out` : the name of the resulting executable, placed in the output directory on the host.
|
|
|
|
# For example, to build a linux/386 binary into `bin/rt`:
|
|
# docker build . --output bin --build-arg os=linux --build-arg arch=386 --build-arg out=rt
|
|
|
|
# Note that the --output <dir> flag refers to the host, outside the container.
