DeploymentWindow

When you create a condition, you can add the DeploymentWindow rule. This section provides a reference for the rule parameters. For more information about rules and conditions, see How do stage conditions work?.

Important

In cases where the DeploymentWindow rule and the CloudWatchAlarm rule are contained together in an entry condition, it is possible that the CloudWatchAlarm alarm might succeed before the deployment window for the DeploymentWindow rule opens. After the deployment window opens, CodePipeline does not check the CloudWatchAlarm alarm again. This can result in an alarm state when the pipeline execution enters the stage.

Configuration parameters

Cron

Required: Yes

The expression that defines the days and times when the deployment will be allowed. Cron expressions are comprised of 6 required fields and one optional field separated by white space. The cron expression fields allow you to specify a schedule pattern with a cron expression as follows.

Field name	Allowed values	Allowed special characters
Seconds	0-59	, - * /
Minutes	0-59	, - * /
Hours	0-23	, - * /
Day-of-month	1-31	, - * ? / L W
Month	0-11 or JAN-DEC	, - * /
Day-of-Week	1-7 or SUN-SAT	, - * ? / L #
Year (Optional)	empty, 1970-2199	, - * /

The '*' character is used to specify all values. For example, "*" in the minute field means "every minute".
The '?' character is allowed for the day-of-month and day-of-week fields. It is used to specify 'no specific value'. This is useful when you need to specify something in one of the two fields, but not the other.
The '-' character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12".
The ',' character is used to specify additional values. For example "MON,WED,FRI" in the day-of-week field means "the days Monday, Wednesday, and Friday".
The '/' character is used to specify increments. For example "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". Specifying '*' before the '/' is equivalent to specifying 0 is the value to start with.
The 'L' character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "last", but it has different meaning in each of the two fields. For example, the value "L" in the day-of-month field means "the last day of the month" - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means "7" or "SAT". But if used in the day-of-week field after another value, it means "the last <specified_day> day of the month" - for example "6L" means "the last friday of the month". You can also specify an offset from the last day of the month, such as "L-3" which would mean the third-to-last day of the calendar month.
The 'W' character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify "15W" as the value for the day-of-month field, the meaning is: "the nearest weekday to the 15th of the month". So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th.
The 'L' and 'W' characters can also be combined for the day-of-month expression to yield 'LW', which translates to "last weekday of the month".
The '#' character is allowed for the day-of-week field. This character is used to specify "the nth" <specified_day> day of the month. For example, the value of "6#3" in the day-of-week field means the third Friday of the month (day 6 = Friday and "#3" = the 3rd one in the month).
The legal characters and the names of months and days of the week are not case sensitive.

TimeZone

Required: Yes

The time zone for the deployment window.
