Packer get instance_id in a variable

[Svetlio Shushkov]

Hi All,

I am using oracle-oci builder to create the instance and the image afterwards, but in between these two, I need to apply some configuration using ansible.

I would like to let ansible know the instance that it needs to do this to (local ansible), since I need to attach a block volume to it.

Is there a normal way of obtaining this information from either packer or the builder or any other way, so that I can configure the instance?

Thanks

Hi there, 

Packer does provide a way for providing the instance id to provisioners using build variables. However, these build variables do vary by builder type as it is on the builder to set the value. If the oracle-oci builder offers access to the instance id you can reference it via ${build.ID} for HCL2 templates or {{build `ID`}} in JSON templates. 

Is the instance ID the information you are looking for?

There are additional build variables such as HOST, Password, etc.
I would suggest giving the build variable a try and seeing if it contains the information you are looking for.

More details on Build Variable can be found https://www.packer.io/docs/templates/hcl_templates/contextual-variables#build-variables

Hey guys,

Thanks for letting me know of this, I wasn't paying attention to those variables.

Thanks again :)
