Examples

Retrieving a bucket's lifecycle management rules.

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

bucket.lifecycle.size #=> 2
rule = bucket.lifecycle.first
rule.action #=> "SetStorageClass"
rule.storage_class #=> "COLDLINE"
rule.age #=> 10
rule.matches_storage_class #=> ["STANDARD", "NEARLINE"]
rule.matches_prefix #=> ["myprefix/foo"]
rule.matches_suffix #=> [".jpg", ".png"]

Updating the bucket's lifecycle rules in a block.

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

bucket.update do |b|
  b.lifecycle do |l|
    # Remove the last rule from the array
    l.pop
    # Remove rules with the given condition
    l.delete_if do |r|
      r.matches_storage_class.include? "NEARLINE"
    end
    # Update rules
    l.each do |r|
      r.age = 90 if r.action == "Delete"
    end
    # Add a rule
    l.add_set_storage_class_rule "COLDLINE", age: 10
  end
end

Methods

#action

def action() -> String

The type of action taken when the rule's conditions are met. Currently, only Delete and SetStorageClass are supported.

Returns

(String) — the current value of action

#action=

def action=(value) -> String

The type of action taken when the rule's conditions are met. Currently, only Delete and SetStorageClass are supported.

Parameter

value (String) — the newly set value

Returns

(String) — the newly set value

#age

def age() -> Integer

The age of a file (in days). This condition is satisfied when a file reaches the specified age.

Returns

(Integer) — the current value of age

#age=

def age=(value) -> Integer

The age of a file (in days). This condition is satisfied when a file reaches the specified age.

Parameter

value (Integer) — the newly set value

Returns

(Integer) — the newly set value

#created_before

def created_before() -> String, Date, nil

A date in RFC 3339 format with only the date part (for instance, "2013-01-15"). This condition is satisfied when a file is created before midnight of the specified date in UTC. When returned by the service, a non-empty value will always be a Date object.

Returns

(String, Date, nil) — the current value of created_before

#created_before=

def created_before=(value) -> String, Date, nil

Parameter

value (String, Date, nil) — the newly set value

Returns

(String, Date, nil) — the newly set value

#custom_time_before

def custom_time_before() -> String, Date, nil

A date in RFC 3339 format with only the date part (for instance, "2013-01-15"). This condition is satisfied when the custom time on an object is before this date in UTC.

Returns

(String, Date, nil) — the current value of custom_time_before

#custom_time_before=

def custom_time_before=(value) -> String, Date, nil

A date in RFC 3339 format with only the date part (for instance, "2013-01-15"). This condition is satisfied when the custom time on an object is before this date in UTC.

Parameter

value (String, Date, nil) — the newly set value

Returns

(String, Date, nil) — the newly set value

#days_since_custom_time

def days_since_custom_time() -> Integer, nil

Represents the number of days elapsed since the user-specified timestamp set on an object. The condition is satisfied if the days elapsed is at least this number. If no custom timestamp is specified on an object, the condition does not apply.

Returns

(Integer, nil) — the current value of days_since_custom_time

#days_since_custom_time=

def days_since_custom_time=(value) -> Integer, nil

Parameter

value (Integer, nil) — the newly set value

Returns

(Integer, nil) — the newly set value

#days_since_noncurrent_time

def days_since_noncurrent_time() -> Integer

Represents the number of days elapsed since the noncurrent timestamp of an object. The condition is satisfied if the days elapsed is at least this number. The value of the field must be a nonnegative integer. If it's zero, the object version will become eligible for Lifecycle action as soon as it becomes noncurrent. Relevant only for versioning-enabled buckets. (See Google::Cloud::Storage::Bucket#versioning?)

Returns

(Integer) — the current value of days_since_noncurrent_time

#days_since_noncurrent_time=

def days_since_noncurrent_time=(value) -> Integer

Parameter

value (Integer) — the newly set value

Returns

(Integer) — the newly set value

#is_live

def is_live() -> Boolean

Relevant only for versioned files. If the value is true, this condition matches live files; if the value is false, it matches archived files.

Returns

(Boolean) — the current value of is_live

Sets the attribute matches_suffix

#noncurrent_time_before

def noncurrent_time_before() -> String, Date, nil

A date in RFC 3339 format with only the date part (for instance, "2013-01-15"). This condition is satisfied when the noncurrent time on an object is before this date in UTC.
