Oscker

Oscker aim to make a generic descriptor to make images for different CSPs.

Run

Specify the cloud vendor and basic image by calling the getHclScript method in Main to generate the hcl script executed by packer

input param

Provisioner

• base_image: The default CPU architecture is X86
• image_name: Name of the created image
• inline: The script to be executed to make the image

Packer needs real resource replacement demo to execute hcl

source "huaweicloud-ecs" "demo" { vpc_id = "demo" subnets = ["demo"] security_groups = ["demo"] } build { sources = ["demo"]
