v0.2.1
v0.2.0
Modules affected
bash-commons
Description
Update to use IMDSv2 by default (still supports manually setting v1 if needed)
IMPORTANT
There is a bug modules/bash-commons/src/aws.sh that will result in an unbound variable error if GRUNTWORK_BASH_COMMONS_IMDS_VERSION is undefined. This is fixed in v0.2.1.
v0.1.9
Modules affected
log.sh
Description
Added convenience function for echo-ing to stderr.
v0.1.8
Modules affected
aws.sh
Description
Introduce support for AWS Instance Metadata Service (IMDS) Version 2. These changes are fully backward compatible, and bash-commons continues to default to Version 1 of the Instance Metadata Service.
You can override the version of IMDS that bash-commons contacts by setting the following environment variable:
GRUNTWORK_BASH_COMMONS_IMDS_VERSION="2"
bash-commons will continue to default to IMDSv1 until we have migrated all our dependent modules to use version 2. Once this migration is complete, we will issue another release that updates bash-commons to use IMDSv2 by default.
For more information on the differences between Instance Metadata Service Versions 1 and 2 see here.
