Consul
Consul Intention
Command: consul intention
The intention
command is used to interact with Connect
intentions. It exposes commands for
creating, updating, reading, deleting, checking, and managing intentions.
This command is available in Consul 1.2 and later.
Intentions are managed primarily via
service-intentions
config
entries after Consul 1.9. Intentions may also be managed via the HTTP
API.
Deprecated - This command is deprecated in Consul 1.9.0 in favor of
using the config entry CLI command. To create an
intention, create or modify a
service-intentions
config
entry for the destination.
