gcloud beta compute diagnose routes - routes to/from Compute Engine virtual machine instances

gcloud beta compute diagnose routes [NAME …] [--container=CONTAINER] [--dry-run] [--external-route-ip=EXTERNAL_ROUTE_IP] [--force-key-file-overwrite] [--plain] [--regexp=REGEXP, -r REGEXP] [--reverse-traceroute] [--ssh-flag=SSH_FLAG] [--ssh-key-file=SSH_KEY_FILE] [--strict-host-key-checking=STRICT_HOST_KEY_CHECKING] [--user=USER] [--zones=ZONE,[ZONE,…]] [--ssh-key-expiration=SSH_KEY_EXPIRATION     | --ssh-key-expire-after=SSH_KEY_EXPIRE_AFTER] [GCLOUD_WIDE_FLAG …] [-- TRACEROUTE_ARGS …]

NOTE: The name filtering will cycle through all the VMs in the project. Depending on the size of the project, this could be a considerable amount of work.

If that is the case, use the --regexp flag to filter down the amount of VMs considered in the filtering.

[NAME …]

If provided, show details for the specified names and/or URIs of resources.

[-- TRACEROUTE_ARGS …]

Flags and positionals passed to the underlying traceroute call. The '--' argument must be specified between gcloud specific args on the left and TRACEROUTE_ARGS on the right. Example:

gcloud beta compute diagnose routes example-instance -- -w 0.5 -q 5 42

--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 Container-Optimized OS virtual machine image. For more information, see https://cloud.google.com/compute/docs/containers

--dry-run

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

--external-route-ip=EXTERNAL_ROUTE_IP

For reverse traceroute, this will be the ip given to the VM instance to traceroute to. This will override all obtained ips.

--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.

--regexp=REGEXP, -r REGEXP

Regular expression to filter the names of the results on. Any names that do not match the entire regular expression will be filtered out.

--reverse-traceroute

If enabled, will also run traceroute from the VM to the host

--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 beta compute diagnose routes 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.

--user=USER

User for login to the selected VMs. If not specified, the default user will be used.

--zones=ZONE,[ZONE,…]

If provided, only resources from the given zones are queried.

At most one of these can be specified:

--ssh-key-expiration=SSH_KEY_EXPIRATION

The time when the ssh key will be valid until, such as "2017-08-29T18:52:51.142Z." This is only valid if the instance is not using OS Login. See $ gcloud topic datetimes for information on time formats.

--ssh-key-expire-after=SSH_KEY_EXPIRE_AFTER

The maximum length of time an SSH key is valid for once created and installed, e.g. 2m for 2 minutes. See $ gcloud topic datetimes for information on duration formats.

Run $ gcloud help for details.
