Usage: consul troubleshoot ports [options]
|
|
Checks ports for TCP connectivity. Add the -ports flag to check specific ports or omit the -ports flag to check default ports.
|
|
Refer to the following reference for default ports: https://developer.hashicorp.com/consul/docs/install/ports
|
|
|
|
consul troubleshoot ports -host localhost
|
|
|
|
or
|
|
export CONSUL_HTTP_ADDR=localhost
|
|
consul troubleshoot ports
|
|
|
|
Use the -ports flag to check non-default ports, for example:
|
|
consul troubleshoot ports -host localhost -ports 1023,1024
|
|
or
|
|
export CONSUL_HTTP_ADDR=localhost
|
|
consul troubleshoot ports -ports 1234,8500
|
