1、现在开始构建Docker镜像,使用指定的镜像名称和标签
# 先进入到DockerFile项目目录文件下
cd ~/../Documents/trae_projects/test
# 指定的镜像名称和标签
docker build -t test:1.0.0 .
# 指定在特定架构平台能运行的镜像
docker buildx build --platform linux/amd64 -t test:1.0.0 -t coderjohnhao/test:1.0.0 .完成后终端会打印日志,如下

docker tag test:1.0.0 coderjohnhao/test:1.0.0 3、现在尝试将镜像推送到Docker Hub。
docker push coderjohnhao/test:1.0.0 终端打印日志,如下
The push refers to repository [docker.io/coderjohnhao/test]

终端直接运行
docker pull coderjohnhao/test:1.0.0
docker run -d -p 3000:3000 coderjohnhao/test:1.0.0使用docker-compose.yml
version: '3.9'
services:
docker-test:
image: 'coderjohnhao/test:1.0.3'
ports:
- '3000:3000'在docker-compose.yml文件夹目录下,执行
docker compose up -d --build
