bash - 来自守护进程的错误响应：当我尝试在容器内提交更改时未能获得摘要：第 1 部分

Question

我想设置一个脚本，将更改提交到 docker 映像。我正在学习如何阅读这篇文章：

脚本完成后如何运行 docker 容器并提交更改？

我做了一些修改以使其适合我的场景。

这是我的“env_setup_script.sh”脚本：

开始.sh：

#!/bin/bash
XSOCK=/tmp/.X11-unix
XAUTH=/tmp/.docker.xauth
touch $XAUTH
xauth nlist $DISPLAY | sed -e 's/^..../ffff/' | xauth -f $XAUTH nmerge -
sudo service docker start

hostusername=$(whoami)

echo -n " Hello, whats your name ?"
read -r
username=$REPLY

docker run \
 --gpus all \
 --rm -it \
 -v $XSOCK:$XSOCK:rw \
 -v $XAUTH:$XAUTH:rw \
 -e DISPLAY=$DISPLAY \
 -e XAUTHORITY=$XAUTH \
 -v /:/home/$username/Shared-$hostusername \
 -t firefox/docker

根据帖子，这是我的：

提交.sh：

#!/bin/bash

# Run a docker with the env boot script

./start.sh

# Get the container ID of the last run docker (above)

export CONTAINER_ID=\docker ps -lq``

echo $CONTAINER_ID

# Commit the container state (returns an image_id with sha256: prefix cut off)# and write the IMAGE_ID to disk at ~/.docker_image_id

(docker commit $CONTAINER_ID | cut -c8-) > docker_image_id

不幸的是它不起作用：

# ./commit.sh    

Hello, whats your name ? mario
