PEcAn docker stack on M1 Mac (POC version)

gistfile1.txt

* built a local ARM tidyverse image (I did this in a tempdir)
	- Dockerfile:
		```
		FROM rocker/r-ver:4.2.1

		ENV S6_VERSION=v2.1.0.2
		ENV RSTUDIO_VERSION=daily
		ENV DEFAULT_USER=rstudio
		ENV PANDOC_VERSION=default
		ENV PATH=/usr/lib/rstudio-server/bin:$PATH

		# Needed for compilation of arrow
		RUN apt-get update \
		  && apt-get install -y --no-install-recommends cmake \
		  && rm -rf /var/lib/apt/lists/*

		# Needed for compilation of duckdb
		RUN sed -i -e 's/-fpic/-fPIC/' /usr/local/lib/R/etc/Makeconf

		RUN /rocker_scripts/install_rstudio.sh
		RUN /rocker_scripts/install_pandoc.sh
		RUN /rocker_scripts/install_tidyverse.sh

		EXPOSE 8787

		CMD ["/init"]
		```
	- `docker build -t pecan/tidyverse:armtest .`
* edited docker/depends/Dockerfile to start `FROM pecan/tidyverse:armtest`, then built depends image:
	```
	cd docker/depends \
	&& docker build \
	--tag pecan/depends:armtest \
	--build-arg R_VERSION=armtest \
	.
	```
* built other images: `cd .. && ./docker.sh -i armtest -r armtest`
* docker.sh failed at ed2 model image (ld can't find -lhdf5_fortran, -lhdf5, -lhdf5_hl)
	
	I left ed2 and maespa unbuilt and finished by building sipnet and API manually
	when doing this again I'll instead comment out the ed2 and maespa images before running docker.sh
	```
	docker build \
        --tag pecan/model-sipnet-git:armtest \
        --build-arg MODEL_VERSION=git \
        --build-arg IMAGE_VERSION=armtest \
        models/sipnet
	docker build \
        --tag pecan/model-sipnet-r136:armtest \
        --build-arg MODEL_VERSION=r136 \
        --build-arg IMAGE_VERSION=armtest \
        models/sipnet
	docker build \
        --tag pecan/api:armtest \
        --build-arg IMAGE_VERSION=armtest \
        --build-arg PECAN_VERSION="1.7.2.9000" \
        --build-arg PECAN_GIT_BRANCH=dash-ess \
        --build-arg PECAN_GIT_CHECKSUM="eed4817b50c9669dae3ebbad010bcf2d8530021f" \
        --build-arg PECAN_GIT_DATE="Wed Sep 14 13:29:13 2022 -0700" \
        apps/api/
    ```

* Reset shared R libraries (have to do this any time switching versions, esp. if changing between ARM and AMD64 stacks):
	```
	docker volume rm pecan_lib
	docker run -ti --rm -v pecan_lib:/rlib pecan/base:armtest cp -a /usr/local/lib/R/site-library/. /rlib/
	```
	If you forget this step, loading any R package with shared objects will give e.g. 
	```
	Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  		unable to load shared object '/usr/local/lib/R/site-library/Rcpp/libs/Rcpp.so': /usr/local/lib/R/site-library/Rcpp/libs/Rcpp.so: cannot open shared object file: No such file or directory
	```


* Let's test! 
	- commented out ed2 and maespa in docker-compose.yml
	- `PECAN_VERSION='armtest' docker-compose up`
	- Images that are still running as AMD64: bety, dbsync, postgres, thredds
