Most
gcloud
commands return a list of resources on success. By default they are pretty-printed on the standard output. The--format=

EXPRESSION
flags along with projections can be used to format and change the default output to a more meaningful result.Use the
--format
flag to change the default output format of a command. Resource formats are described in detail below.Use the
--filter
flag to select resources to be listed. For details run $ gcloud topic filters.Use resource-keys to reach resource items through a unique path of names from the root. For details run $ gcloud topic resource-keys.
Use projections to list a subset of resource keys in a resource. For details run $ gcloud topic projections.
Note: To refer to a list of fields you can sort, filter, and format by for each resource, you can run a list command with the format set to
text
orjson
. For example, $ gcloud compute instances list --limit=1 --format=text.To work through an interactive tutorial about using the filter and format flags instead, see: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/GoogleCloudPlatform/cloud-shell-tutorials&page=editor&tutorial=cloudsdk/tutorial.md
- Formats
-
A format expression is used to change the default output format of a command.
Many output formats are available; some for pretty printing human-readable
output and others for returning machine-readable output.
A format expression has 3 parts:
NAME
-
name
ATTRIBUTES
-
[
[no-]attribute-name
[=value
] [, … ]]
PROJECTION
-
(
resource-key
[, …])
NAME
is required,ATTRIBUTES
are optional, andPROJECTIONS
may be required for some formats. Unknown attribute names are silently ignored. Eachgcloud
list
command has a default format expression. The--format
flag can alter or replace the default. For example,--format="[box]"
adds box decorations to a default table, and--format=json
lists the resource injson
format. The formats and format specific attributes are:config
-
A dictionary of dictionaries in config style.
The format attributes are:
export
- Display the dictionary as a list of system specific environment export commands.
unset
- Display the dictionary as a list of system specific environment unset commands.
csv
-
Comma Separated Values with no
keys. This format requires a projection to define the values to be printed.
To use
\n
or\t
as an attribute value please escape the\
with your shell's escape sequence, exampleseparator="\\n"
for bash.The format attributes are:
delimiter="string"
- The string printed between list value items, default ";".
no-heading
- Disables the initial key name heading record.
separator="string"
- The string printed between values, default ",".
terminator="string"
- The string printed after each record, default "\n" (newline).
default
-
An alias for the
yaml
format. To override usegcloud config set core/default_format
property. diff
-
A unified diff of the first two projection columns.
The format attributes are:
format
- The format of the diffed resources. Each resource is converted to this format and the diff of the converted resources is displayed. The default is 'flattened'.
disable
-
Disables formatted output and does not consume the resources. Equivalent to the
none
format, but also short-circuits early for commands that return pageable lists. flattened
-
A flattened tree. Each output line contains one
key
:value
pair.The format attributes are:
no-pad
-
Don't print space after the separator. The default adjusts the space to align
the values into the same output column. Use
no-pad
for comparing resource outputs. separator=
SEPARATOR
-
Print
SEPARATOR
between thekey
andvalue
. The default is ": ".
get
-
Equivalent to the
value[no-transforms]
format. Default transforms are not applied to the displayed values. json
-
JSON, JavaScript Object Notation.
The format attributes are:
no-undefined
- Does not display resource data items with null values.
list
-
An ordered list of items.
The format attributes are:
always-display-title
- Display the title even if there are no records.
compact
- Display all items in a record on one line.
multi
-
Each projection key must have a subformat defined by the :format=FORMAT-STRING
attribute. For example,
`--format="multi(data:format=json, info:format='table[box](a, b, c)')"`
formats the
data
field as JSON and theinfo
field as a boxed table.The format attributes are:
separator
- Separator string to print between each format. If multiple resources are provided, the separator is also printed between each resource.
none
- Disables formatted output and consumes the resources.
object
-
Bypasses JSON-serialization and prints the object representation of each
resource.
The format attributes are:
separator
- The line printed between resources.
terminator
- The line printed after each resource.
table
-
Aligned left-adjusted columns with optional title, column headings and sorting.
This format requires a projection to define the table columns. The default
column headings are the disambiguated right hand components of the column keys
in ANGRY_SNAKE_CASE. For example, the projection keys (first.name, last.name)
produce the default column heading ('NAME', 'LAST_NAME').
If
--page-size
=N
is specified then output is grouped into tables with at mostN
rows. Headings, alignment and sorting are done per-page. The title, if any, is printed before the first table.If screen reader option is True, you may observe flattened list output instead of a table with columns. Please refer to $ gcloud topic accessibility to turn it off.
The format attributes are:
all-box
- Prints a box around the entire table and each cell, including the title if any.
box
- Prints a box around the entire table and the title cells if any.
format=
FORMAT-STRING
-
Prints the key data indented by 4 spaces using
FORMAT-STRING
which can reference any of the supported formats. no-heading
- Disables the column headings.
margin=N
- Right hand side padding when one or more columns are wrapped.
pad=N
-
Sets the column horizontal pad to
N
spaces. The default is 1 for box, 2 otherwise. title=
TITLE
-
Prints a centered
TITLE
at the top of the table, within the table box ifbox
is enabled.
text
-
An alias for the
flattened
format. value
-
CSV with no heading and <TAB> separator instead of <COMMA>. Used to
retrieve individual resource values. This format requires a projection to define
the value(s) to be printed.
To use
\n
or\t
as an attribute value please escape the\
with your shell's escape sequence, exampleseparator="\\n"
for bash.The format attributes are:
delimiter="string"
- The string printed between list value items, default ";".
quote
- "…" quote values that contain delimiter, separator or terminator strings.
separator="string"
- The string printed between values, default "\t" (tab).
terminator="string"
- The string printed after each record, default "\n" (newline).
yaml
-
YAML, YAML ain't markup language.
The format attributes are:
null="string"
-
Display string instead of
null
for null/None values. no-undefined
- Does not display resource data items with null values.
version=VERSION
- Prints using the specified YAML version, default 1.2.
All formats have these attributes:
disable
- Disables formatted output and does not consume the resources.
json-decode
- Decodes string values that are JSON compact encodings of list and dictionary objects. This may become the default.
pager
- If True, sends output to a pager.
private
- Disables log file output. Use this for sensitive resource data that should not be displayed in log files. Explicit command line IO redirection overrides this attribute.
transforms
-
Apply projection transforms to the resource values. The default is format
specific. Use
no-transforms
to disable.
- EXAMPLES
-
List a table of compute instance resources sorted by
name
with box decorations and titleInstances
:gcloud compute instances list --format="table[box,title=Instances](name:sort=1, zone:label=zone, status)"
List a nested table of the quotas of a region:
gcloud compute regions describe us-central1 --format="table(quotas:format='table(metric,limit,usage)')"
Print a flattened list of global quotas in CSV format:
gcloud compute project-info describe --flatten="quotas[]" --format="csv(quotas.metric,quotas.limit,quotas.usage)"
List the disk interfaces for all compute instances as a compact comma separated list:
gcloud compute instances list --format="value(disks[].interface.list())"
List the URIs for all compute instances:
gcloud compute instances list --format="value(uri())"
List all compute instances with their creation timestamps displayed according to the local timezone:
gcloud compute instances list --format="table(name,creationTimestamp.date(tz=LOCAL))"
List the project authenticated user email address:
gcloud info --format="value(config.account)"
List resources filtered on repeated fields by projecting subfields on a repeated message:
gcloud alpha genomics readgroupsets list --format="default(readGroups[].name)"
Return the scope of the current instance:
gcloud compute zones list --format="value(selfLink.scope())"
selfLink is a fully qualified name. (e.g. 'https://www.googleapis.com/compute/v1/projects/my-project/zones/us-central1-a') The previous example returns a list of just the names of each zone (e.g. 'us-central1-a'). This is because selfLink.scope() grabs the last part of the URL segment. To extract selfLink starting from /projects and return the scope of the current instance:
gcloud compute zones list --format="value(selfLink.scope(projects))"
List all scopes enabled for a Compute Engine instance and flatten the multi-valued resource:
gcloud compute instances list --format="flattened(name,serviceAccounts[].email,serviceAccounts[].scopes[].basename())"
Display a multi-valued resource's service account keys with the corresponding service account, extracting just the first '/' delimited part with segment(0):
gcloud iam service-accounts keys list --iam-account[email protected]--project=test-minutia-123 --format="table(name.scope(serviceAccounts).segment(0):label='service Account',name.scope(keys):label='keyID',validAfterTime)"
The last example returns a table with service account names without their full paths, keyID and validity.
