createSharedSecret

Purpose Create shared secret for secure communication

Syntax createSharedSecret

createSharedSecret -file <filename>

Description createSharedSecret creates a shared secret file used for secure

communication between job managers and workers. T he file is named

secret in the curren t fold er.

createSharedSecret -file <filename> create a s hared secret file as

the giv en filename.

Before passing sensitive data from one service to another (e .g., between

job manager and workers), these services need to establish a trust

relationship using a shared secret. This script creates a file that serves

as a shared secret betw een the services. Each service is trusted that

has access to that secret file.

Create the secret file only once per cluster on o ne machine, then copy

it into the location specified by

SHARED_SECRET_FILE in the mdce_def

file on each machine before starting any job managers or workers. In a

shared file system, all nodes can po int to the same file. Shared secrets

can be reused in subse quent sessions.

Examples Create a shared secret file in a central location for all the nodes of the

cluster:

cd matlabInstallDir/toolbox/distcomp/bin

createSharedSecret -file /share/secret

Then make sure that the nodes’ shared or copied mdce_def files set

the parameter

SHARED_SECRET_FILE to /share/secret before starting

the m dce service on each.
