dshell: A little wrapper around the docker-compose run command that intelligently gets you a shell inside a container

dshell

#!/bin/bash

if [ ! -z $1 ]; then
  MATCHER=$1
else
  # Try to guess the project based on directory name
  MATCHER=`pwd | sed 's/\/.*\///'`
fi

echo "Looking for web container named '$MATCHER'..."

CONTAINER_ID=`docker ps -a -f name=web_run | grep $MATCHER | head -n 1 | cut -d' ' -f1`
#CONTAINER_ID=`docker ps -a -f name=web_run | head -n 2 | tail -n 1 | cut -d' ' -f1`

if [ -z $CONTAINER_ID ]; then
  echo "No container exists, creating it (hit enter after a sec to bring up terminal)..."
  docker-compose run --service-ports --use-aliases web /bin/bash
  exit 0
fi

STATUS=`docker inspect --format='{{json .State.Status}}' $CONTAINER_ID`
echo -n "Found $CONTAINER_ID and it is currently $STATUS. "

if [[ "$STATUS" = '"running"' ]]; then
    echo "Shelling in..."
    docker exec -i -t $CONTAINER_ID /bin/bash
else
    echo "Starting and shelling in..."
    docker start $CONTAINER_ID
    docker exec -i -t $CONTAINER_ID /bin/bash
fi
