     1  # Overview
     2  
     3  The `cnitool` is a utility that can be used to test a CNI plugin
     4  without the need for a container runtime. The `cnitool` takes a
     5  `network name` and a `network namespace` and a command to `ADD` or
     6  `DEL`,.i.e, attach or detach containers from a network. The `cnitool`
     7  relies on the following environment variables to operate properly:
     8  
     9  * `NETCONFPATH`: This environment variable needs to be set to a
    10    directory. It defaults to `/etc/cni/net.d`. The `cnitool` searches
    11    for CNI configuration files in this directory with the extension
    12    `*.conf` or `*.json`. It loads all the CNI configuration files in
    13    this directory and if it finds a CNI configuration with the `network
    14    name` given to the cnitool it returns the corresponding CNI
    15    configuration, else it returns `nil`.
    16  * `CNI_PATH`: For a given CNI configuration `cnitool` will search for
    17    the corresponding CNI plugin in this path.
