Description:
  The replace command is used to replace a set of resources by filename or
  stdin.  JSON and YAML formats are accepted.

  Valid resource types are:

    * node
    * bgpPeer
    * hostEndpoint
    * workloadEndpoint
    * ipPool
    * policy
    * profile

  Attempting to replace a resource that does not exist is treated as a
  terminating error.

  The output of the command indicates how many resources were successfully
  eplaced, and the error reason if an error occurred.

  The resources are replaced in the order they are specified.  In the event of
  a failure replacing a specific resource it is possible to work out which
  resource failed based on the number of resources successfully replaced.

  When replacing a resource, the complete resource spec must be provided, it is
  not sufficient to supply only the fields that are being updated.
```

### Examples

```
# Replace a set of resources (of mixed type) using the data in resources.yaml.
# Results indicate that 8 resources were successfully replaced.
$ calicoctl replace -f ./resources.yaml
Successfully replaced 8 resource(s)

# Replace a policy based on the JSON passed into stdin.
# Results indicate the policy does not exist.
$ cat policy.json | calicoctl replace -f -
Failed to replace any 'policy' resources: resource does not exist: Policy(name=dbPolicy)
```

### Options

```
-f --filename=<FILENAME>   Filename to use to replace the resource.  If set
                           to "-" loads from stdin.
```

### General options

```
-c --config=<CONFIG>       Path to the file containing connection
                           configuration in YAML or JSON format.
                           [default: /etc/calico/calicoctl.cfg]
```
