$ gcloud compute firewall-rules create --network=NETWORK \
      default-allow-ssh --allow tcp:22

POSITIONAL ARGUMENTS

[USER@]INSTANCE

Specifies the instance to SSH into.
USER specifies the username with which to SSH. If omitted, $USER from the environment is selected.
INSTANCE specifies the name of the virtual machine instance to SSH into.

[-- SSH_ARGS ...]

Flags and positionals passed to the underlying ssh implementation.

The '--' argument must be specified between gcloud specific args on the left and SSH_ARGS on the right. Example:

$ gcloud alpha compute ssh example-instance --zone us-central1-a \ -- -vvv -L 80:%INSTANCE%:80

FLAGS

--command=COMMAND

A command to run on the virtual machine.
Runs the command on the target instance and then exits.

--container=CONTAINER

The name or ID of a container inside of the virtual machine instance to connect to. This only applies to virtual machines that are using a Google Container-Optimized virtual machine image. For more information, see cloud.google.com/compute/docs/containers

--dry-run

Print the equivalent scp/ssh command that would be run to stdout, instead of executing it.

--force-key-file-overwrite

If enabled, the gcloud command-line tool will regenerate and overwrite the files associated with a broken SSH key without asking for confirmation in both interactive and non-interactive environments.
If disabled, the files associated with a broken SSH key will not be regenerated and will fail in both interactive and non-interactive environments.

--plain

Suppress the automatic addition of ssh(1)/scp(1) flags. This flag is useful if you want to take care of authentication yourself or use specific ssh/scp features.

--ssh-flag=SSH_FLAG

Additional flags to be passed to ssh(1). It is recommended that flags be passed using an assignment operator and quotes. This flag will replace occurences of %USER% and %INSTANCE% with their dereferenced values. Example:

$ gcloud alpha compute ssh example-instance --zone us-central1-a \
    --ssh-flag="-vvv" --ssh-flag="-L 80:%INSTANCE%:80"

is equivalent to passing the flags --vvv and -L 80:162.222.181.197:80 to ssh(1) if the external IP address of 'example-instance' is 162.222.181.197.

--ssh-key-file=SSH_KEY_FILE

The path to the SSH key file. By default, this is ~/.ssh/google_compute_engine.

--strict-host-key-checking=STRICT_HOST_KEY_CHECKING

Override the default behavior of StrictHostKeyChecking for the connection. By default, StrictHostKeyChecking is set to 'no' the first time you connect to an instance, and will be set to 'yes' for all subsequent connections. STRICT_HOST_KEY_CHECKING must be one of: yes, no, ask.

--zone=ZONE

Zone of the instance to connect to. If not specified and the compute/zone property isn't set, you may be prompted to select a zone.
To avoid prompting when this flag is omitted, you can set the compute/zone property:

$ gcloud config set compute/zone ZONE

A list of zones can be fetched by running:

$ gcloud compute zones list

To unset the property, run:

$ gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

At most one of these may be specified:

--internal-ip

Connect to instances using their internal IP addresses rather than their external IP addresses. Use this to connect from one instance to another on the same VPC network, over a VPN connection, or between two peered VPC networks.
For this connection to work, you must configure your networks and firewall to allow SSH connections to the internal IP address of the instance to which you want to connect.
To learn how to use this flag, see cloud.google.com/compute/docs/instances/connecting-advanced#sshbetweeninstances

--tunnel-through-iap

Tunnel the ssh connection through the Cloud Identity-Aware Proxy.
