private ipv4 & public ip is not exposed via afterburn in Oracle which is required for some tests. So I need to add it upstream. For now I will use systemd hack. Correct me if I am mistaken. @tormath1

Thanks a lot, overally it looks good. I just have one request, usually the ore command is used to create and upload an image on the cloud provider. Is that possible to implement this?

It's then used like that: https://github.com/flatcar/scripts/blob/d2c217cb741debc9becda0bda86347319f17a65c/ci-automation/vendor-testing/stackit.sh#L24-L48

We first upload the image then we use the resulting image ID in the kola run command.

It seems that the Go SDK has a Retry mechanism, that would be interesting to use it: https://pkg.go.dev/github.com/oracle/oci-go-sdk/v65#hdr-Retry

Mantle has its own Retry function as well:

$ go doc util.Retry
package util // import "github.com/flatcar/mantle/util"

func Retry(attempts int, delay time.Duration, f func() error) error
    Retry calls function f until it has been called attemps times, or succeeds.
    Retry delays for delay between calls of f. If f does not succeed after
    attempts calls, the error from the last call is returned.

Done, tested ore image uploads.

➜ IMAGE_ID=$(./bin/ore oracle \
  --oracle-config-file="${ORACLE_CONFIG_FILE:-$HOME/.oci/config}" \
  --oracle-profile="${ORACLE_PROFILE:-DEFAULT}" \
  --oracle-compartment-id="${ORACLE_COMPARTMENT_ID}" \
  --oracle-bucket="${ORACLE_BUCKET}" \
  create-image \
  --board="${CIA_ARCH:-amd64}-usr" \
  --name="flatcar-oracle-upload-test-$(date +%s)" \
  --file="${ORACLE_IMAGE_NAME}"
)

echo "${IMAGE_ID}"
ocid1.image.oc1.ap-hyderabad-1.aaaaaaaairf3z42rr5qlebezgmxpyaitpyok7bm24inistcnujec7jiohbqa

Added retry also, using DefaultRetryPolicy of OCI SDK:

Retries 409 IncorrectState
Retries 409 LockConflict
Retries 429 TooManyRequests
Retries 5xx, except 501 MethodNotImplemented
Uses exponential backoff with jitter
Maximum wait per retry is about 30s + 1s jitter
Up to 8 attempts
Cumulative backoff is about 1.5 minutes
With eventual consistency handling, up to 9 attempts
Eventual consistency cumulative backoff is about 4 minutes
