cndi E200 - cndi-config must contain exactly one leader node

[johnstonmatt]

description

The cndi CLI exits with error code 200 when you call cndi overwrite (aka. cndi ow) with a cndi-config file which either designates multiple leaders, or designates none. CNDI is used to create clusters of one or many nodes, and there always must be one node with the role of "leader". Note how in the config below there is exactly one node with the property "role" set to "leader".

resolution tips

In order to resolve this issue, select a node to be leader of the cluster, then call cndi ow again.
