Functions

func AssumeIamRole

func AssumeIamRole(iamRoleOpts options.IAMRoleOptions) (*sts.Credentials, error)

Make API calls to AWS to assume the IAM role specified and return the temporary AWS credentials to use that role

func AssumeRoleAndUpdateEnvIfNecessary

func AssumeRoleAndUpdateEnvIfNecessary(terragruntOptions *options.TerragruntOptions) error

Assume an IAM role, if one is specified, by making API calls to Amazon STS and setting the environment variables we get back inside of terragruntOptions.Env

func CreateAwsSession

func CreateAwsSession(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (*session.Session, error)

Returns an AWS session object. The session is configured by either:

• The provided AwsSessionConfig struct, which specifies region (required), profile name (optional), and IAM role to assume (optional).
• The provided TerragruntOptions struct, which specifies any IAM role to assume (optional).

Note that if the AwsSessionConfig object is null, this will return default session credentials using the default credentials chain of the AWS SDK.

func CreateAwsSessionFromConfig

func CreateAwsSessionFromConfig(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (*session.Session, error)

Returns an AWS session object for the given config region (required), profile name (optional), and IAM role to assume (optional), ensuring that the credentials are available.

func GetAWSAccountID

func GetAWSAccountID(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (string, error)

Get the AWS account ID of the current session configuration

func GetAWSCallerIdentity

func GetAWSCallerIdentity(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (sts.GetCallerIdentityOutput, error)

Return the AWS caller identity associated with the current set of credentials

func GetAWSIdentityArn

func GetAWSIdentityArn(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (string, error)

Get the ARN of the AWS identity associated with the current set of credentials

func GetAWSPartition

func GetAWSPartition(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (string, error)

Get the AWS Partition of the current session configuration

func GetAWSUserID

func GetAWSUserID(config *AwsSessionConfig, terragruntOptions *options.TerragruntOptions) (string, error)

Get the AWS user ID of the current session configuration

func MarshalPolicy

func MarshalPolicy(policy Policy) ([]byte, error)
