Usage: consul acl set-agent-token [options] TYPE TOKEN
This command will set the corresponding token for the agent to use. If token
persistence is not enabled, then tokens uploaded this way are not persisted
and if the agent reloads then the tokens will need to be set again.
Token Types:
default The default token is the token that the agent will use for
both internal agent operations and operations initiated by
the HTTP and DNS interfaces when no specific token is provided.
If not set the agent will use the anonymous token.
agent The token that the agent will use for internal agent operations.
If not given then the default token is used for these operations.
recovery This sets the token that can be used to access the Agent APIs in
the event that the ACL datacenter cannot be reached.
replication This is the token that the agent will use for replication
operations. This token will need to be configured with read access
to whatever data is being replicated.
config_file_service_registration This is the token that the agent uses to register services
and checks defined in config files. This token needs to
be configured with permission for the service or checks
being registered. If not set, the default token is used.
If a service or check definition contains a 'token'
field, then that token is used instead.
Example:
$ consul acl set-agent-token default c4d0f8df-3aba-4ab6-a7a0-35b760dc29a1
