rds – create, delete, or modify an Amazon rds instance

Synopsis

• Creates, deletes, or modifies rds instances. When creating an instance it can be either a new instance or a read-only replica of an existing instance. This module has a dependency on python-boto >= 2.5. The ‘promote’ command requires boto >= 2.18.0. Certain features such as tags rely on boto.rds2 (boto >= 2.26.0)

Requirements

The below requirements are needed on the host that executes this module.

• boto

• python >= 2.6

Parameters

Parameter	Choices/Defaults	Comments
apply_immediately boolean	Choices: no ← yes	Used only when command=modify. If enabled, the modifications will be applied as soon as possible rather than waiting for the next preferred maintenance window.
aws_access_key string		AWS access key. If not set then the value of the AWS_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string		AWS secret key. If not set then the value of the AWS_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
backup_retention -		Number of days backups are retained. Set to 0 to disable backups. Default is 1 day. Valid range: 0-35. Used only when command=create or command=modify.
backup_window -		Backup window in format of hh24:mi-hh24:mi. If not specified then a random backup window is assigned. Used only when command=create or command=modify.
character_set_name -		Associate the DB instance with a specified character set. Used with command=create.
command - / required	Choices: create replicate delete facts modify promote snapshot reboot restore	Specifies the action to take. The 'reboot' option is available starting at version 2.0
db_engine -	Choices: mariadb MySQL oracle-se1 oracle-se2 oracle-se oracle-ee sqlserver-ee sqlserver-se sqlserver-ex sqlserver-web postgres aurora	The type of database. Used only when command=create. mariadb was added in version 2.2
db_name -		Name of a database to create within the instance. If not specified then no database is created. Used only when command=create.
debug_botocore_endpoint_logs boolean added in 2.8	Choices: no ← yes	Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
ec2_url string		Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
engine_version -		Version number of the database engine to use. Used only when command=create. If not specified then the current Amazon RDS default engine version is used
force_failover boolean added in 2.0	Choices: no ← yes	Used only when command=reboot. If enabled, the reboot is done using a MultiAZ failover.
instance_name -		Database instance identifier. Required except when using command=facts or command=delete on just a snapshot
instance_type -		The instance type of the database. Must be specified when command=create. Optional when command=replicate, command=modify or command=restore. If not specified then the replica inherits the same instance type as the source instance.
iops -		Specifies the number of IOPS for the instance. Used only when command=create or command=modify. Must be an integer greater than 1000.
license_model -	Choices: license-included bring-your-own-license general-public-license postgresql-license	The license model for this DB instance. Used only when command=create or command=restore.
maint_window -		Maintenance window in format of ddd:hh24:mi-ddd:hh24:mi. (Example: Mon:22:00-Mon:23:15) If not specified then a random maintenance window is assigned. Used only when command=create or command=modify.
multi_zone boolean	Choices: no yes	Specifies if this is a Multi-availability-zone deployment. Can not be used in conjunction with zone parameter. Used only when command=create or command=modify.
new_instance_name -		Name to rename an instance to. Used only when command=modify.
option_group -		The name of the option group to use. If not specified then the default option group is used. Used only when command=create.
parameter_group -		Name of the DB parameter group to associate with this instance. If omitted then the RDS default DBParameterGroup will be used. Used only when command=create or command=modify.
password -		Password for the master database username. Used only when command=create or command=modify.
port -	Default: "3306 for mysql, 1521 for Oracle, 1433 for SQL Server, 5432 for PostgreSQL."	Port number that the DB instance uses for connections. Used only when command=create or command=replicate. Prior to 2.0 it always defaults to null and the API would use 3306, it had to be set to other DB default values when not using MySql. Starting at 2.0 it automatically defaults to what is expected for each db_engine.
profile string		Uses a boto profile. Only works with boto >= 2.24.0.
publicly_accessible -		explicitly set whether the resource should be publicly accessible or not. Used with command=create, command=replicate. Requires boto >= 2.26.0
region string / required		The AWS region to use. If not specified then the value of the EC2_REGION environment variable, if any, is used. aliases: aws_region, ec2_region
security_groups -		Comma separated list of one or more security groups. Used only when command=create or command=modify.
security_token string		AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
size -		Size in gigabytes of the initial storage for the DB instance. Used only when command=create or command=modify.
snapshot -		Name of snapshot to take. When command=delete, if no snapshot name is provided then no snapshot is taken. If used with command=delete with no instance_name, the snapshot is deleted. Used with command=facts, command=delete or command=snapshot.
source_instance -		Name of the database to replicate. Used only when command=replicate.
subnet -		VPC subnet group. If specified then a VPC instance is created. Used only when command=create.
tags -		tags dict to apply to a resource. Used with command=create, command=replicate, command=restore. Requires boto >= 2.26.0

vpc_security_groups -		Comma separated list of one or more vpc security group ids. Also requires `subnet` to be specified. Used only when command=create or command=modify.
wait boolean	Choices: no ← yes	When command=create, replicate, modify or restore then wait for the database to enter the 'available' state. When command=delete wait for the database to be terminated.

Notes

Note

• If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION

• Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html

• AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
