Description

It will be a nice feature to add the support of external file for credentials. Actually the builder support :

• Static credentials
• Environment variables

The documentation (https://www.packer.io/docs/builders/outscale#authentication) mention the support of Shared credential file, but I haven't found documentation or support of this feature. It will improve the security in usage of credentials. (cc @Hakujou )

Use Case(s)

• Reducing the risks to commit credentials in the JSON
• Reducing the risks to type secret in a terminal by settings environment variable

Potential configuration

Something like :

"credentials_file" = "<path>"
"credentials_profile = "<profile>"

content of the file :

[<profile>]
access_key=...
secret_key=..
