Trying to run the docker image built with `make docker-build-dev` would
result in an error at startup:
standard_init_linux.go:228: exec user process caused: no such file or directory
This was due to the dev docker image lacking `dumb-init` which is used
by `docker-entrypoint.sh`.
This commit updates the dev dockerfile to add dumb-init. It also adds
additional packages so that the dev image aligns with the release image.
Pass correct context to docker build for multiarch and dev build targets.
* fixed missing file errors; bumped boundary version
* downgraded alpine due to build issues
* fixing makefile
* bumping boundary and alpine versions
* fixed docker directory in makefile and dockerfile
* updating dev.dockerfile & makefile
* updated dockerfile to support multi-arch; added new section in Make for multi-arch
* adding a line to changelog
* switching base image to hashicorp mirror
