When you try to add a node to an existing cluster of Starcluster, some plugins can fail depending if you are in master or secondary node.
If your plugin has something like:
for node in nodes:
do something...
when you add a node with
starcluster addnode myexistingcluster
the previous form does not works.
So how would try to differentiate the plugin's operations for master and secondaries nodes.
How can I check if I am in the master from inside the plugin? I tried with the index of nodes list but does not works.
given plugins on_add_node signature
def on_add_node(self, node, nodes, master, user, user_shell, volumes):
You can call
node.is_master()
