Local tester for Rocker RStudio image on M1 Macs

pl-rocker-local-test.sh

#!/bin/bash

# Local tester for the PrairieLearn Workspaces version of Rocker. We'd like to
# find out if this truly works on M1 Macs (and why). The macOS version of
# Docker Desktop should handle permissions appropriately here, but this script
# may not work on Windows and Linux. If you are not using macOS, just use
# normal Rocker instead of this script.

# USAGE INSTRUCTIONS
# 1. Edit the LOCAL_MOUNT variable below to whatever working directory you'd
#    like to mount into the container. The session uses /home/rstudio/workspace
#    as the working directory, so your mount will be at: /home/rstudio/workspace/rocker-mounted
# 2. Run this script with:
#      bash ./pl-rocker-local-test.sh
# 3. You'll see some warnings and errors about s6 that you can ignore,
#    and eventually "Starting nginx". Then go here in your browser:
#      http://localhost:3939/rstudio

# ---

# Pull the PrairieLearn version of the Rocker image
# (After the first download, comment out this line for faster restarts.)
sudo docker pull prairielearn/workspace-rstudio

# Prepare a local directory to be mounted inside the container read-write
LOCAL_MOUNT="$HOME/rocker-mounted"
mkdir -p "$LOCAL_MOUNT"

sudo docker run -it --rm -v "$LOCAL_MOUNT:/home/rstudio/workspace/rocker-mounted" -p 127.0.0.1:3939:3939 -u 0 prairielearn/workspace-rstudio

Works macOS Monterey 12.5 on an M1 14inch pro; Docker version 20.10.17, build 100c70180f

Thanks a mil!
