DDS's SSH plug-in is capable to deploy DDS agents on any resource machine available for password-less access (public key, ssh agent, etc.).
In order to define resources for the SSH plug-in we use a comma-separated values (CSV) configuration file, in cases if you want to deploy agents on several computing nodes.
The ssh plug-in can also spawn agents on the local machine only. In this case you don't need a configuration file - just use dds-submit -n X, where X is a desired number of agents to spawn.
As for the configuration file. Fields are normally separated by commas. If you want to put a comma in a field, you need to decorate it with quotes around. Also 3 escape sequences are supported.
DDS's SSH plug-in configuration fields:
- An id (must be any unique string).
This id string is used just to distinguish different DDS workers in the plug-in. - A host name with or without a login, in a form:
[email protected] - Additional SSH params (could be empty).
- A remote working directory.
- A number of agents to spawn.
An example of the SSH plug-in configuration file:
r1, [email protected], -p24, /tmp/test, 10
# this is a comment
r2, [email protected],,/home/user/dds,10
125, user2@host, , /tmp/test,
Call using a given configuration file:
dds-submit -r ssh -c your-ssh-Resource-definition-config-fileCall using a local system only to spawn 10 DDS agents on it:
dds-submit -r ssh -n 10
