Why it happens

The deployment reaches Docker Compose startup, but the OpenSearch container cannot be created. The nested Docker runtime is not permitted to set rlimit type 8, commonly associated with the container's memlock limit. This is a DinD or host-permission mismatch rather than a Composer or Git failure.
