利用命令：

docker build -t welcome-to-docker .

创建容器时遇到如下报错：

ERROR: failed to solve: node:18-alpine: failed to resolve source metadata for docker.io/library/node:18-alpine: failed to authorize: failed to fetch oauth token: Post "https://auth.docker.io/token": dial tcp [2a03:2880:f112:83:face:b00c:0:25de]:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

考虑由于网络问题导致Docker 无法从 Docker Hub 直接拉取 node:18-alpine 镜像。

解决方式：

利用命令手动拉取 node:18-alpine 镜像：

docker pull node:18-alpine

运行以上命令后，可以正常创建镜像、运行容器。
