Documented steps

  1. 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.
  2. 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'.
  3. Match the --allow at build time to the daemon-granted entitlement or the build fails with an entitlement-not-allowed error.
  4. Official docs: https://docs.docker.com/reference/cli/docker/buildx/build/ ; https://docs.docker.com/build/building/builders/
