Using the asdf version manager to manage versions of various binaries like terraform, vault or packer is easily done by following the instructions below:
asdf plugin add terraform asdf install terraform latest asdf global terraform 0.14.9 asdf list terraform 0.14.9 terraform --version Terraform v0.14.9
Trying to follow along the example in the Exoscale article about creating custom templates, you get the error about exoscale-import not found, when you are trying to validate the packer template.
Make sure that you use a current packer installation as the exoscale-import was not supported in the older versions.
kosmas:terraform (add_vault *%)$ packer --version 1.0.4
So after installing the latest version the above error goes away
kosmas:terraform (add_vault *%)$ packer --version 1.6.1
You are trying to build a QEMU image with Packer, but you are getting the error suggesting to use the PACKER_LOG=1 option. But there is no indication where to place it in the command line.
Put it at the begging of the command line as folows:
kosmas:terraform (add_vault *%)$ PACKER_LOG=1 packer build vault_orchestration/template.json
