calicoctl apply

Usage:
  calicoctl apply --filename=<FILENAME> [--config=<CONFIG>]

Examples:
  # Apply a policy using the data in policy.yaml.
  calicoctl apply -f ./policy.yaml

  # Apply a policy based on the JSON passed into stdin.
  cat policy.json | calicoctl apply -f -

Options:
  -h --help                 Show this screen.
  -f --filename=<FILENAME>  Filename to use to apply the resource.  If set to
                            "-" loads from stdin.
  -c --config=<CONFIG>      Path to the file containing connection
                            configuration in YAML or JSON format.
                            [default: /etc/calico/calicoctl.cfg]

Description:
  The apply command is used to create or 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, and profile.

  When applying a resource:
  -  if the resource does not already exist (as determined by it's primary
     identifiers) then it is created
  -  if the resource already exists then the specification for that resource is
     replaced in it's entirety by the new resource specification.

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

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

  When applying a resource to perform an update, the complete resource spec
  must be provided, it is not sufficient to supply only the fields that are
  being updated.

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

# Apply two policy resources based on the JSON passed into stdin.
$ cat policy.json | calicoctl apply -f -
Successfully applied 2 'policy' resource(s)

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

-c --config=<CONFIG>      Path to the file containing connection
                          configuration in YAML or JSON format.
