1. 创建镜像1.1 从dockerhub上拉取docker pull ****:***1.2 保存镜像docker save -o *.tar image:tag1.3 从镜像文件中创建docker load *.tar1.4 更新镜像docker commit containerid image:tag2. 创建容器2.1 英伟达GPU下docker run --gpus device0 --nethost -it -v /:/mnt --shm-size12g --memory-swap-1 --namecontainername image:tag bash-v挂载路径宿主机路径容器路径--net网络端口映射host表示容器网络和宿主机完全联通。-u: 用户权限设置root表示该镜像用户权限为root用户防止镜像中权限限制。注意谨慎使用docker exec进入容器保存文件。使用docker exec -it ID bash进入容器时保存文件一定不要保存文件在容器环境中否则退出时文件会消失。2.2 昇腾NPU下Atlas800T A2服务器npu 为Ascend910B3(8*64GB)docker run -it --nethost \ -v /home/jiao/train_example/:/home/yolo/ \ --nameyolov11n \ --device/dev/davinci6 \ --device/dev/davinci7 \ --device/dev/davinci_manager \ --device/dev/hisi_hdc \ --device/dev/devmm_svm \ -v /usr/local/Ascend/driver:/usr/local/Ascend/driver \ -v /usr/local/Ascend/firmware:/usr/local/Ascend/firmware \ -v /usr/local/sbin/npu-smi:/usr/local/sbin/npu-smi \ -v /usr/local/sbin:/usr/local/sbin \ -v /etc/hccn.conf:/etc/hccn.conf \ yolov11-train:v1 \ /bin/bash3.
