Documented steps
Pass the entitlement at build time with --allow, e.g. docker buildx build --allow network.host . for host network mode, --allow security.insecure to run the build unsandboxed, or --allow device for CDI device access.
The BuildKit daemon must also grant the entitlement: for a non-docker builder create it with the flag, e.g. docker buildx create --use --name insecure --buildkitd-flags '--allow-insecure-entitlement security.insecure'.
Match the --allow at build time to the daemon-granted entitlement or the build fails with an entitlement-not-allowed error.

Known gotchas
--allow on the client alone is insufficient; the BuildKit daemon must have the matching --allow-insecure-entitlement or --allow-insecure-entitlement-devices flag set at builder creation.
network.host in a Bake file or Dockerfile requires granting the network.host entitlement at invocation (interactive prompt or --allow=network.host).
security.insecure is dangerous — it runs RUN steps without the sandbox; use only for trusted Dockerfiles.
