Bash script to translate docker-compose service name with hostname:port

durl.sh

#!/bin/bash

########## C O N F I G ##########
DOCKER_HOST_NAME=localhost
#################################

cmd="curl $@"
service_name=`echo $cmd | sed -n  's/.* \([a-zA-Z0-9_][a-zA-Z0-9_]*\)\/.*/\1/p'`

row=`docker-compose ps |grep _${service_name}_1`

### Check if the service does exist in the current project
if [[ $row == "" ]]; then
  echo "There is no service called '$service_name'";
  exit -1;
fi

status=`echo $row | awk '{print $3}'`

### Check if the service is running
if [[ $status != "Up" ]]; then
  status=`echo $row | awk '{print $4}'`

  ### Check if the service is running
  if [[ $status != "Up" ]]; then
    echo "Service is not running";
    exit -1;
  fi

  port=`echo $row | awk '{print $5}'`; port=${port:8:5}
else
  port=`echo $row | awk '{print $4}'`; port=${port:8:5}
fi

real_host="${DOCKER_HOST_NAME}:$port"

### Build the find/replace strings with leading space and trailing / for a 'more exact' string match
IFS="¢"
find=" ${service_name}/"
replace=" ${real_host}/"
unset IFS

echo $real_host

cmd=${cmd/${find}/${replace}}

### Run the translated curl command
$cmd

Running ./durl.sh users/v1/users/1 will be translated into curl docker:32878/v1/users/1

What the script does is to translate the users hostname into the docker host + port (in the example docker:32878)

I have added an alias so that I can just run durl xxx.

As an addition docker-machine ip default could be added to find the DOCKER_HOST_NAME as well
