devenv

#!/usr/bin/env bash

#
# A wrapper around the docker command to make it easier to run commands in 
# the app container accross Linux and MacOS. On MacOS, the user and group
# ids are different than on Linux, so we need to pass them in as environment
# variables to the container. This script will set the USER_ID and GROUP_ID
# environment variables to the current user and group ids.
#
# The USER_ID and GROUP_ID environment variables are used in the docker-compose.yml
# file to set the user and group ids in the app container that is the same as the
# current user and group ids on the host machine. This is done to avoid permission
# issues when creating files in the app container.
#

#
# Usage:
#
#   devenv build       - Build the app container
#   devenv up          - Start the app container
#   devenv stop        - Stop the app container
#   devenv down        - Stop and remove the app container
#   devenv shell       - Start a shell in the app container
#   devenv <command>   - Run a command in the running app container
#

    # passed in as environment variables. Instead, we'll set the USER_ID and GROUP_ID

    # app container.
    #
    # This will on MacOS because Docker Desktop for Mac uses a file sharing system
    # that doesn't require the user and group ids to be the same in the container
    # as on the host machine.
