Usage: consul acl policy create -name NAME [options]

|
|
|
The -rules option values allows loading the value from stdin, a file
|
|
or the raw value. To use stdin pass '-' as the value. To load the value
|
|
from a file prefix the value with an '@'. Any other values will be used
|
|
directly.
|
|
|
|
Create a new policy:
|
|
|
|
$ consul acl policy create -name "new-policy" \
|
|
-description "This is an example policy" \
|
|
-datacenter "dc1" \
|
|
-datacenter "dc2" \
|
|
-rules @rules.hcl
