fix Command
The packer fix command takes a template and finds backwards incompatible
parts of it and brings it up to date so it can be used with the latest version
of Packer. After you update to a new Packer release, you should run the fix
command to make sure your templates work with the new release.
The fix command will output the changed template to standard out, so you should redirect standard using standard OS-specific techniques if you want to save it to a file. For example, on Linux systems, you may want to do this:
$ packer fix old.json > new.json
If fixing fails for any reason, the fix command will exit with a non-zero exit status. Error messages appear on standard error, so if you're redirecting output, you'll still see error messages.
-> Even when Packer fix doesn't do anything to the template, the template will be outputted to standard out. Things such as configuration key ordering and indentation may be changed. The output format however, is pretty-printed for human readability.
The full list of fixes that the fix command performs is visible in the help
output, which can be seen via packer fix -h.
