docker build报错：unknown-sha256:

docker打包时出现如下错误:

ERROR: failed to solve: node:18-alpine: failed to resolve source metadata for docker.io/library/node:18-alpine: 
failed commit on ref "unknown-sha256:xxxx": "unknown-sha256:xxx" failed size validation: 1355 != 1181: failed precondition

查阅得知是镜像问题，跟换docker镜像即可：
