The image name is long — assign it to a variable first:

  IMG=harbor.baai.ac.cn/flagos-app/sglang0.5.18-ascend-cann9.0.0:2.1.2-0.1.dev1_g2e568482e

The two approaches below are alternatives — pick the one that matches how your host runs containers:

With the container toolkit

Start an interactive shell:

  docker run --rm -it \
  --privileged \
  -e ASCEND_VISIBLE_DEVICES=0,1 \
  $IMG bash

Start the app with its default settings:

  docker run --rm -it \
  --privileged \
  -e ASCEND_VISIBLE_DEVICES=0,1 \
  $IMG

Pass arguments to the launcher:

  docker run --rm -it \
  --privileged \
  -e ASCEND_VISIBLE_DEVICES=0,1 \
  $IMG sglang-serve --model-path <path> --port 9000

Without a toolkit — plain docker / podman

Start an interactive shell:

  docker run --rm -it \
  --device /dev/davinci0 \
  --device /dev/davinci1 \
  --device /dev/davinci_manager \
  --device /dev/devmm_svm \
  --device /dev/hisi_hdc \
  -v /usr/local/Ascend/driver:/usr/local/Ascend/driver \
  -v /usr/local/dcmi:/usr/local/dcmi \
  -v /usr/local/sbin/npu-smi:/usr/local/sbin/npu-smi \
  $IMG bash

Start the app with its default settings:

  docker run --rm -it \
  --device /dev/davinci0 \
  --device /dev/davinci1 \
  --device /dev/davinci_manager \
  --device /dev/devmm_svm \
  --device /dev/hisi_hdc \
  -v /usr/local/Ascend/driver:/usr/local/Ascend/driver \
  -v /usr/local/dcmi:/usr/local/dcmi \
  -v /usr/local/sbin/npu-smi:/usr/local/sbin/npu-smi \
  $IMG

Pass arguments to the launcher:

  docker run --rm -it \
  --device /dev/davinci0 \
  --device /dev/davinci1 \
  --device /dev/davinci_manager \
  --device /dev/devmm_svm \
  --device /dev/hisi_hdc \
  -v /usr/local/Ascend/driver:/usr/local/Ascend/driver \
  -v /usr/local/dcmi:/usr/local/dcmi \
  -v /usr/local/sbin/npu-smi:/usr/local/sbin/npu-smi \
  $IMG sglang-serve --model-path <path> --port 9000
