use jp merge two json files, it works for me.

  # install jp
  yum install epel-release -y
  yum install jq -y
  jq --version

  # add registry-cbu.languoguang.com
  cat /etc/docker/daemon.json
  jq -s '.[0]."insecure-registries"=([.[]."insecure-registries"]|flatten)|.[0]' /etc/docker/daemon.json $PWD/ci/daemon.json > /etc/docker/daemon.extension.json
  mv -f /etc/docker/daemon.extension.json /etc/docker/daemon.json
  cat /etc/docker/daemon.json

  echo "restart docker..."
  sudo systemctl daemon-reload
  sudo systemctl restart docker
