+### Why do I see `get_mempolicy: Operation not permitted` when running in Docker?
+
+In some container environments (like Docker), NUMA-related syscalls used by vLLM (e.g., `get_mempolicy`, `migrate_pages`) are blocked/denied in the runtime's default seccomp/capabilities settings. This may lead to warnings like `get_mempolicy: Operation not permitted`. Functionality is not affected, but NUMA memory binding/migration optimizations may not take effect and performance can be suboptimal.
+
+To enable these optimizations inside Docker with the least privilege, you can follow below tips:
+
+```bash
+docker run ... --cap-add SYS_NICE --security-opt seccomp=unconfined  ...
+
+# 1) `--cap-add SYS_NICE` is to address `get_mempolicy` EPERM issue.
+
+# 2) `--security-opt seccomp=unconfined` is to enable `migrate_pages` for `numa_migrate_pages()`.
+# Actually, `seccomp=unconfined` bypasses the seccomp for container,
+# if it's unacceptable, you can customize your own seccomp profile,
+# based on docker/runtime default.json and add `migrate_pages` to `SCMP_ACT_ALLOW` list.
+
+# reference : https://docs.docker.com/engine/security/seccomp/
+```
+
+Alternatively, running with `--privileged=true` also works but is broader and not generally recommended.
+
+In K8S, the following configuration can be added to workload yaml to achieve the same effect as above:
+
+```yaml
+securityContext:
+  seccompProfile:
+    type: Unconfined
+  capabilities:
+    add:
+    - SYS_NICE
+```
