Problem

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.

Solution

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
