[BUG] failed to start docker container in orin target with error: failed to create endpoint on network bridge, operation not supported

Dear @lizhensheng,
To run docker services on the Target, developers must follow the steps to rebuild the kernel and filesystem per the instructions in Compiling the Kernel (Kernel 5.15) | NVIDIA Docs
with the following modifications:

  1. For step 4, include libncurses-dev and vim in the apt-get install command.
  2. For step 6, use defconfig.
  3. For step 7, after starting the menuconfig with make -C kernel O=${PWD}/out-linux menuconfig, press ENTER to select General setup. Navigate to Namespaces support and press the space bar to enable. Press ENTER to select Namespaces support. Navigate to User namespace and press the space bar to enable. Save the configuration and exit the menuconfig. Save the menuconfig with the make -C kernel O=${PWD}/out-linux savedefconfig command. When copying the updated defconfig, use cp ${PWD}/out-linux/defconfig kernel/arch/arm64/configs/tegra_defconfig.
  4. For step 11.d, replace instances of <kernel_version> in the code snippet with 5.15.98-rt-tegra before executing the commands.
  5. For step 12.c.i, replace the <fstype> string with standard before saving the new update_rfs.CONFIG.json file. Before running Build-FS per #12.c.i.2, execute the following snippet to remove all YAML entries for kernel modules for the updates/dkms path
python3 -B - << END
import yaml
with open('/drive/drive-linux/filesystem/copytarget/manifest/copytarget-kernel-modules.yaml', 'r') as f:
    data = yaml.safe_load(f)
data['fileList'] = [data_ for data_ in data['fileList'] if data_['destination'].find('updates/dkms') == -1]
with open('/drive/drive-linux/filesystem/copytarget/manifest/copytarget-kernel-modules.yaml', 'w') as f:
    yaml.dump(data, f)

Let me know if it works for you.
