Short Description
This is a stand alone FME engine that listens for jobs on a port
Full Description

This container will listen on a port (7777 on the container) for job requests and execute them. The format for sending job requests is detailed in the python script below.

There are 2 volumes in this container:

  • /fmeengine/workspaces - this is where the workspaces you want to run should be located
  • /fmeengine/logs - this is where log files are output

You can mount a directory on your host machine that contains the workspaces you want to run using this image. Alternatively you could create your own container from this one with your workspaces already inside the container.

If you want to be able to access logs, you can also mount the logs directory.

Start this container with a command similar to:

docker run --rm -p 7777:7777 -v ~/workspaces:/fmeengine/workspaces -v ~/logs:/fmeengine/logs safesoftware/fme-engine-2017

And send it jobs using the below python script using the command: <host> <port> <FME command line>

For a more complete example see

import struct
import socket
import sys

if len(sys.argv) != 4:
   print "Usage: " + sys.argv[0] + " <host> <port> <request>"

TCP_IP = sys.argv[1] # The host name to send the request to
TCP_PORT = sys.argv[2] # The port to send the request to

request_str = sys.argv[3] # the parameters to pass to FME on the command line

# pack the messages we are going to send
keyword = struct.pack('!i' + str(len(keyword_str)) + 's', len(keyword_str), keyword_str)
request = struct.pack('!i' + str(len(request_str)) + 's', len(request_str), request_str)

# open the socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, int(TCP_PORT)))

# send the request

# receieve the size of the message which is the first 4 bytes
data = s.recv(4)
recv_size = struct.unpack('!i', data)[0]

# recieve the message
data = s.recv(recv_size)
result_message = struct.unpack('!' + str(recv_size) + 's', data)[0]

# print what we got back from the engine
print result_message

# close the socket
