I like Brandon's first notion: "have your task query for what param it
should use based on the value of env.host_string", which seems like a much
better idea than the second that he gave an example for. I might be barking
up the wrong tree, but would something like the following work?
@parallel
def task(param_table):
param = param_table[env.host_string]
run("command with {}".format(param))
def launcher():
param_table = {
'192.168.1.100': 'param1',
'192.168.1.200': 'param2',
}
execute(task, param_table, hosts=list(param_table))
