This Terraform upgrade must be done with great care, as it can cause irreparable damage to a deployment.
This should be done AFTER changes for #265 have been approved via PR and merged into main
This is a PREREQ for upgrading Cumulus to v18
This should be done in isolation from any other terraform changes
Steps:
[x] Checkout and pull the latest code on the main branch (which should include changes made for #265)
[x] Run make all-up-yes to make sure there are no pending terraform changes prior to upgrading terraform
[x] BACKUP all tfstate files in the "tfstate" bucket:
make bash
SUFFIX=$(aws sts get-caller-identity --query Account --output text | cut -c 9-12)
aws s3 cp --recursive s3://csda-${CUMULUS_PREFIX}-tfstate-${SUFFIX}/${TS_ENV} s3://csda-${CUMULUS_PREFIX}-tfstate-${SUFFIX}/${TS_ENV}-0.13.6
[x] In .terraform-version change the version number to 1.5.7
[x] Run make all-init
[x] Run make all-plan to examine planned changes, if any (not sure if the version change will cause any errors due to deprecations and such)
[x] If there aren't any errors from the plan, run make all-up-yes, which should update the tfstate files to match the format for the new terraform version (NOTE: this should show 0 changes for any of the modules, and should simply update the version of the tfstate files)
