gcloud topic formats

NAME
gcloud topic formats - resource formats supplementary help
DESCRIPTION
Mostgcloud commands return alist of resources on success. By default they are pretty-printed on the standardoutput. The--format=NAME[ATTRIBUTES](PROJECTION)and--filter=EXPRESSION flags along withprojections can be used to format and change the default output to a moremeaningful result.

Use the--format flag to change the default output format of acommand. Resource formats are described in detail below.

Use the--filter flag to select resources to be listed. For detailsrun $gcloud topic filters.

Use resource-keys to reach resource items through a unique path of names fromthe root. For details run $gcloud topic resource-keys.

Use projections to list a subset of resource keys in a resource. For details run$gcloud topicprojections.

Note: To refer to a list of fields you can sort, filter, and format by for eachresource, you can run a list command with the format set totext orjson. For example, $gcloud compute instanceslist --limit=1 --format=text.

To work through an interactive tutorial about using the filter and format flagsinstead, 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-readableoutput 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 areoptional, andPROJECTIONS may be required for someformats. Unknown attribute names are silently ignored.Eachgcloudlistcommand has a default format expression. The--format flag canalter 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 Valueswith no keys. This format requires a projection to define the values to beprinted.

To use\n or\t as an attribute value please escapethe\ 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 theyaml format. To override usegcloud configset 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 formatand the diff of the converted resources is displayed. The default is'flattened'.
disable
Disables formatted output and does not consume the resources. Equivalent to thenone format, but also short-circuits early for commands that returnpageable lists.
flattened
A flattened tree. Each output line contains onekey:value pair.

The format attributes are:

no-pad
Don't print space after the separator. The default adjusts the space to alignthe values into the same output column. Useno-pad for comparingresource outputs.
separator=SEPARATOR
PrintSEPARATOR between thekey andvalue. The default is ": ".
get
Equivalent to thevalue[no-transforms] format. Default transformsare 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-STRINGattribute. For example,
`--format="multi(data:format=json, info:format='table[box](a, b, c)')"`

formats thedata field as JSON and theinfo field as aboxed table.

The format attributes are:

separator
Separator string to print between each format. If multiple resources areprovided, 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 eachresource.

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 defaultcolumn headings are the disambiguated right hand components of the column keysin 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 outputis grouped into tables with at mostN rows. Headings,alignment and sorting are done per-page. The title, if any, is printed beforethe first table.

If screen reader option is True, you may observe flattened list output insteadof a table with columns. Please refer to $gcloud topic accessibilityto 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 usingFORMAT-STRING which can reference any of the supportedformats.
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 toN spaces. The defaultis 1 for box, 2 otherwise.
title=TITLE
Prints a centeredTITLE at the top of the table, withinthe table box ifbox is enabled.
text
An alias for theflattened format.
value
CSV with no heading and <TAB> separator instead of <COMMA>. Used toretrieve individual resource values. This format requires a projection to definethe value(s) to be printed.

To use\n or\t as an attribute value please escapethe\ 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 ofnull 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 dictionaryobjects. 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 notbe displayed in log files. Explicit command line IO redirection overrides thisattribute.
transforms
Apply projection transforms to the resource values. The default is formatspecific; table-like formats may define default transforms to certain columns.Useno-transforms to disable.
EXAMPLES
List a table of compute instance resources sorted byname with boxdecorations and titleInstances:
gcloudcomputeinstanceslist--format="table[box,title=Instances](name:sort=1, zone:label=zone, status)"

List a nested table of the quotas of a region:

gcloudcomputeregionsdescribeus-central1--format="table(quotas:format='table(metric,limit,usage)')"

Print a flattened list of global quotas in CSV format:

gcloudcomputeproject-infodescribe--flatten="quotas[]"--format="csv(quotas.metric,quotas.limit,quotas.usage)"

List the disk interfaces for all compute instances as a compact comma separatedlist:

gcloudcomputeinstanceslist--format="value(disks[].interface.list())"

List the URIs for all compute instances:

gcloudcomputeinstanceslist--format="value(uri())"

List all compute instances with their creation timestamps displayed according tothe local timezone:

gcloudcomputeinstanceslist--format="table(name,creationTimestamp.date(tz=LOCAL))"

List the project authenticated user email address:

gcloudinfo--format="value(config.account)"

List resources filtered on repeated fields by projecting subfields on a repeatedmessage:

gcloudalphagenomicsreadgroupsetslist--format="default(readGroups[].name)"

Return the scope of the current instance:

gcloudcomputezoneslist--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 theURL segment. To extract selfLink starting from /projects and return the scope ofthe current instance:

gcloudcomputezoneslist--format="value(selfLink.scope(projects))"

List all scopes enabled for a Compute Engine instance and flatten themulti-valued resource:

gcloudcomputeinstanceslist--format="flattened(name,serviceAccounts[].email,serviceAccounts[].scopes[].basename())"

Display a multi-valued resource's service account keys with the correspondingservice account, extracting just the first '/' delimited part with segment(0):

gcloudiamservice-accountskeyslist--iam-account=svc-2-123@test-minutia-123.iam.gserviceaccount.com--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 fullpaths, keyID and validity.
