Packer 1.7.2 can not find Linux 8.4 images using source "oracle-oci"

[Svetlio Shushkov]

Hello,

Since recently, I had to introduce changes to the packer code, so that it creates images from a base image, using the "base_image_filter" option. 

This part of source "oracle-oci", and the code could potentially use two types of images, which are both in the same compartment. The code I use for finding both the images looks like this:

base_image_filter {

  compartment_id           = "ocid1.compartment.oc1..EXAMPLE"

  display_name_search      = "^img_oci_oel_8\\.4.*"

  operating_system         = "Oracle Linux"

  operating_system_version = "8.4"

}

The two base images at my disposal have the following names:

img_oci_oel_8.4_123456_1.11.22.3333

img_oci_oel_7.9_123456_1.11.22.3333

Now, when I try this with 7.9:

  display_name_search      = "^img_oci_oel_7\\.9.*"

  operating_system_version = "7.9"

packer manages to find the image and I can proceed.

However, if I try the first piece of code, it errors out with message:

==> oracle-oci.custom-db-dev-image: Using existing SSH private key

==> oracle-oci.custom-db-dev-image: Pausing after run of step 'StepKeyPair'. Press enter to continue.

==> oracle-oci.custom-db-dev-image: Creating instance...

==> oracle-oci.custom-db-dev-image: Problem creating instance: base_image_filter returned no images

==> oracle-oci.custom-db-dev-image: Problem creating instance: base_image_filter returned no images

==> oracle-oci.custom-db-dev-image: Step "stepCreateInstance" failed

I tried different combinations for operating_system_version and operating_system, and the only thing that really did work was if I change the regexp for display_name_search to "^img_oci_oel_8.*", but I lose the minor version part, so it doesn't really work for me, as I have to comply with specific minor versions (part of the name).

When I started an instance from the Linux 8 image, I get the following in the /etc/os-release:

NAME="Oracle Linux Server"

VERSION="8.4"

ID="ol"

ID_LIKE="fedora"

VARIANT="Server"

VARIANT_ID="server"

VERSION_ID="8.4"

PLATFORM_ID="platform:el8"

PRETTY_NAME="Oracle Linux Server 8.4"

ANSI_COLOR="0;31"

CPE_NAME="cpe:/o:oracle:linux:8:4:server"

HOME_URL="https://linux.oracle.com/"

BUG_REPORT_URL="https://bugzilla.oracle.com/"

ORACLE_BUGZILLA_PRODUCT="Oracle Linux 8"

ORACLE_BUGZILLA_PRODUCT_VERSION=8.4

ORACLE_SUPPORT_PRODUCT="Oracle Linux"

ORACLE_SUPPORT_PRODUCT_VERSION=8.4

With 7.9 I get the same, just that "8" is "7" and "4" is "9".

Please tell me if there's something wrong I am doing, or if there's some sort of a problem with Packer itself.

Packer version: 1.7.2

OCI version: 3.0.1

Thanks
