Client command line usage

The client (mcc) is used to interact with the daemon (mccd). It is installed on every node in the network.

General options

-s /tmp/.mcc-socket
--unix /tmp/.mcc-socket

The daemon's UNIX socket path. The client uses this socket to talk to the daemon.

Commands

mcc --help

Print help.

mcc --version

Print MCC version.

mcc id

Get current node's ID.

mcc parent

Get parent node's socket address (ip:port).

mcc health

destination

Destination node ID.

source

mcc generate-node-certificate [options] [output-directory]

Generate node certificate and private key. This is alternative way of provisioning the nodes that does not require using self-service portal. Easy to automate with IaC tools.

-p /etc/mcc/network-certificate.txt
--parent /etc/mcc/network-certificate.txt

Path to your network certificate.

--stdin

Read network private key from standard input.

output-directory

Output directory (default is /etc/mcc).

mcc generate-dependent-node-certificate [options] ipv4-address [output-directory]

Generate dependent node certificate and private key.

-p /etc/mcc/network-certificate.txt
--parent /etc/mcc/network-certificate.txt

Path to your network certificate.

--stdin

Read network private key from standard input.

ip-address

IPv4 address outside MCC network to which the traffic will be directed. Only addresses from private networks (RFC 1918) are allowed here.

output-directory

Output directory (default is /etc/mcc/dependent-nodes).

mcc certificates [configuration-file]

-f table
--output-format table
