1. Local env: Ubuntu CLI, terraform

2. Error messages: sts get caller identity error, "signature does not match"

2.2 check aws sts command (same error)

soyi@SOYI /mnt/c/Users/SOYI/tf-test/fundamental-aws-infra/terraform $ aws sts get-caller-identity

An error occurred (SignatureDoesNotMatch) when calling the GetCallerIdentity operation: Signature expired: 20230807T110934Z is now earlier than 20230808T053813Z (20230808T055313Z - 15 min.)

 

3. resolve: 

3.1 check the aws configure credentials first

3.2 if 3.1 is ok, then synchronize the ntpdate if the env is Ubuntu like -

# run following command if it's Ubuntu
$ sudo ntpdate ntp.ubuntu.com
 8 Aug 14:55:29 ntpdate[1292]: step time server 91.189.91.157 offset +67418.817306 sec
 
# the result means it's done.

# if ntpdate command is not found, then install ntp as below.
sudo apt install ntp && ntpdate -y
