plan: avoid nil pointer dereference in OCI provider build#65
Merged
Conversation
If OCI authentication setup fails (missing compartment OCID for instance principal mode, or LoadOCIConfig error) the local `config` is nil while err is non-nil. The next line then dereferenced `config.ZoneCacheDuration` and panicked. Move the ZoneCacheDuration assignment and the NewOCIProvider call into the `err == nil` guard so the nil config can never be dereferenced. Signed-off-by: Tamal Saha <tamal@appscode.com>
