About configuring calicoctl
calicoctl commands require access to the Calico datastore. In most
calicoctl cannot achieve this connection by default. You can provide
calicoctl with the information it needs using either of the following.
Configuration file: by default,
calicoctlwill look for a configuration file at
/etc/calico/calicoctl.cfg. You can override this using the
--configoption with commands that require datastore access. The file can be in either YAML or JSON format. It must be valid and readable by
calicoctl. A YAML example follows.
apiVersion: projectcalico.org/v3 kind: CalicoAPIConfig metadata: spec: datastoreType: "etcdv3" etcdEndpoints: "http://etcd1:2379,http://etcd2:2379" ...
Environment variables: If
calicoctlcannot locate, read, or access a configuration file, it will check a specific set of environment variables.
Refer to the section that corresponds to your datastore type for a full set of options and examples.
Note: When running
calicoctlinside a container, any environment variables and configuration files must be passed to the container so they are available to the process inside. It can be useful to keep a running container (that sleeps) configured for your datastore, then it is possible to
execinto the container and have an already configured environment.
