Error: 404;NotAuthorizedOrNotFound - caused by hard-coded compute image IDs in the wrong region

A terraform apply throws this error:

│ Error: 404-NotAuthorizedOrNotFound, Authorization failed or requested resource not found.

Suggestion: instead of hard-coded into a locals section in the variables.tf file, use a data lookup using the correct region / shape.

Workaround: If anyone else is using the eu-amsterdam-1 region you can use these:

    // Canonical-Ubuntu-22.04-Minimal-aarch64-2023.04.18-0 eu-amsterdam-1
    source_id   = "ocid1.image.oc1.eu-amsterdam-1.aaaaaaaa4yojwha4rdsnagwul4ncgy45lx7q2g3pd5ru2io6rsx6pog35mfq"

    // Canonical-Ubuntu-20.04-Minimal-2023.04.19-0 eu-amsterdam-1
    source_id   = "ocid1.image.oc1.eu-amsterdam-1.aaaaaaaaml7w5cdrj2fzoa7yaaa4ynymkolvshyz3cc4rbxymk52kcwxt6ma"

If you're in another region, use the oci command to look them. You'll need your compartment ID.

oci compute image list --shape "VM.Standard.E2.1.Micro" --compartment-id ${YOUR_COMPARTMENT_ID}
