如何将 "gcloud compute operations list" 与实例名称过滤器一起使用？
How does one use "gcloud compute operations list" with a filter by instance name?
根本问题是我有一个项目有数以万计的操作，因此很难追踪与正在创建或删除的特定实例相关的操作。所以，我正在寻找一种按目标列出操作的方法。
已弃用的 gcutil 文档讨论了将过滤器表达式设置为可能 filter operations by target instance name or instance selfLink, but there doesn't seem to be any mention of a similar filter expression in gcloud compute operations list described here:
gcloud compute operations list [NAME …] [--format FORMAT] [--help] [--limit LIMIT] [--log-http] [--project PROJECT_ID] [--quiet, -q] [--regexp REGEXP, -r REGEXP] [--sort-by SORT_BY] [--trace-token TRACE_TOKEN] [--uri] [--global | --regions [REGION,…] | --zones [ZONE,…]] [-h]
唯一列出的非全局标志如下：
--global
If provided, only global resources are shown.
--limit LIMIT
The maximum number of results.
--regexp REGEXP, -r REGEXP
A regular expression to filter the names of the results on. Any names that do not match the entire regular expression will be filtered out.
--regions [REGION,…]
If provided, only regional resources are shown. If arguments are provided, only resources from the given regions are shown.
--sort-by SORT_BY
A field to sort by. To perform a descending-order sort, prefix the value of this flag with a tilde (~).
--uri
If provided, the list command will only print URIs for the resources returned. If this flag is not provided, the list command will print a human-readable table of useful resource data.
--zones [ZONE,…]
If provided, only zonal resources are shown. If arguments are provided, only resources from the given zones are shown.
此外，gcutil 文档给出的示例似乎不起作用：
$ gcutil listoperations --zone us-east1-a --filter="target eq '.*dhuo.*'"

Error: Invalid value for field 'filter': 'target eq '.*dhuo.*''. Unrecognized field name in list filter: target.
尽管原始 API 文档将 'target' 描述为 example here:
Filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must contain the following:
FIELD_NAME COMPARISON_STRING LITERAL_STRING
FIELD_NAME: The name of the field you want to compare. The field name must be valid for the type of resource being filtered. Only atomic field types are supported (string, number, boolean). Array and object fields are not currently supported. For example, if you search for machineType in the Firewalls collection, the filter will fail, because the machineType field is specific to instances and other resources do not have that property.
COMPARISON_STRING: The comparison string, either eq (equals) or ne (not equals).
LITERAL_STRING: The literal string value to filter to. The literal value must be valid for the type of field (string, number, boolean). For string fields, the literal value is interpreted as a regular expression using RE2 syntax. The literal value must match the entire field. For example, when filtering instances by name, name eq my-instance won't work, but name eq .*my-instance will work.
For example, for Operation resources, you could filter by the type of the operation:
filter=operationType ne insert
The above filter returns only results whose type field does not equal insert. You can also enclose your literal string in single, double, or no quotes. For example, all three of the following would be valid expressions:
filter=operationType ne "insert"
filter=operationType ne 'insert'
filter=operationType ne insert
If you use a complex regular expression, you need to encode the special characters, including quotes. Consider the following regular expression:
target eq 'example-name-[0-9]+'
To use the expression, you would need to encode it:
filter=target+eq+%27example-name-%5B0-9%5D%2B%27
If you are using the API through a client, such as client libraries, or gcloud compute, keep in mind that your client might encode your regular expression automatically so that you will not need to encode it yourself.
我是否做错了什么，是否确实可以根据我尝试插入的实例的名称过滤区域操作？
我不确定如何使用 gcloud 执行此操作，但您仍然可以使用 gcutil：
gcutil listoperations --zone us-east1-a --filter="targetLink eq '.*dhuo.*'"
所以它几乎和你的一样，但应该使用 'targetLink' 而不是 'target'。
如果您想使用 gcloud 并专门搜索目标，您也可以这样做：
$ gcloud compute operations list | awk ' ~ /dhuo\./ {print [=10=]}'
