Terragrunt image tagged with 0.11.15 has an incompatible terragrunt version (too fresh)

[JZfi]

It seems that the new terragrunt build system packs an incompatible terragrunt version (0.29.0) with the new terraform 0.11.15. You will get HCL-related errors even if there are only old .tfvars/.tf files in our repo. The new tf 0.11.15 version is needed as the provider signing keys at Hashicorp were changed.

$ docker run -ti --rm alpine/terragrunt:0.11.15 bash
bash-5.1# terragrunt --version
terragrunt version v0.29.0

$ docker run -ti --rm alpine/terragrunt:0.11.14 bash
bash-4.4# terragrunt --version
terragrunt version v0.18.6

The error we encounter with the new terragrunt

terragrunt get --terragrunt-source-update
Error reading file at path terragrunt.hcl: open [..]/terragrunt.hcl: no such file or directory
Unable to determine underlying exit code, so Terragrunt will exit with error code 1

The old terragrunt works for our purposes and we bypass this issue atm. using this Dockerfile

FROM alpine/terragrunt:0.11.14
RUN apk add --update --no-cache curl unzip

RUN curl -o terraform.zip https://releases.hashicorp.com/terraform/0.11.15/terraform_0.11.15_linux_amd64.zip
RUN unzip terraform.zip
RUN cp terraform /usr/local/bin/terraform

Thanks for the report, do we have any tickets from Terragrunt about this issue?

terraform 0.11 is bit old to me and imcompatible for all new versions after 0.12+. Yesterday Terraform 1.0 GA was released.

Should we move on to focus on latest version, more than to spend time on these 3+ years old versions?

i would recommend to use the work around so it doesn't block your project, then think about to upgrade your terrafom project to latest ASAP, better to v1.0 GA release directly
