Get a shell prompt, inside a container

shell.sh

#!/usr/bin/env bash

# How to use me:
#  1. put me into any bin path, or run me using a full path (probably make me executable.)
#  2. cd into any path in which you would like to have shell access
#  3. run me, and you will be entered into an alternate shell with more tools 
#

# define which image to use as a command shell image
#
# * this image is still under development, and has some quirks.
# * you will need to occasionally update this image: docker pull quay.io/wunder/wundertools-image-fuzzy-developershell
# * you can report any image related issues here: https://github.com/wunderkraut/wundertools-image-fuzzy-developershell/issues

# define what paths are used to bind/mount into the container
PATH_TARGET="$(pwd)"
PATH_HOME="${HOME}"

# Run a container:
#
# --rm -ti : remove the container after running, give it a tty, and attach input
#
# Map 3 host paths into the container (add more as needed)
# --volume="${PATH_TARGET}:/app/target" \                 <-- the current host path will be mapped to /app/target in the container
# --volume="${PATH_HOME}/.gitconfig:/app/.gitconfig" \    <-- you may need to use ssh, so use the host keys
# --volume="${PATH_HOME}/.ssh:/app/.ssh" \                <-- you may use a github token, so save it if so
#
# Tell docker what directory to run the command inside the container
# -w=/app \
#
# $@ will pass all command arguments to the docker command, so composer receives your command
#
docker run --rm -t -i \
    --volume="${PATH_TARGET}:/app/target" \
    --volume="${PATH_HOME}/.gitconfig:/app/.gitconfig" \
    --volume="${PATH_HOME}/.ssh:/app/.ssh" \
    -w=/app/target \
    ${DOCKER_IMAGE_DEVELOPERTOOL} \
    $@

# Notes:
#
# * The will run zsh inside a container, AND THEN REMOVE THE CONTAINER and all of the container changes upon exit
# * this process is not perfect, and may once in a while require some manual support in removing dead containers
#
# - if zsh crashes, the container will exit, but will not remove itself.  You will need to clean it yourself
#
# - this doesn't link to any other containers.  Consider adding something like "--link MyDBContainerName:db.app"
