项目目录

➜  ehandbook ls -alh
total 38800
drwxr-xr-x   8 weimo  staff   256B  7 22 17:22 .
drwx------@ 79 weimo  staff   2.5K  7 22 12:42 ..

-rw-r--r--   1 weimo  staff   4.4K  7 22 17:37 ehandbook.js

编写docker-compose.yaml

version: "0.0.1"

services:
  app:
    build: ./
    ports:
      - 8888:8888
    volumes:
      - ./:/app
    environment:
      - TZ=Asia/Shanghai

编写dockerfile

FROM node:16-alpine
ADD . ./app
WORKDIR /app
# RUN npm install
CMD pwd && ls && echo "启动服务~" && node ehandbook.js

构建镜像

➜  ehandbook docker build -t ehandbook:v0.0.1 .

运行容器

➜  ehandbook docker run -p 8888:8888 --name ehandbookcon ehandbook:v0.0.1

push镜像到hub

首先要登录（梯子

➜  ehandbook docker login
Log in with your Docker ID or email address to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com/ to create one.
You can log in with your password or a Personal Access Token (PAT). Using a limited-scope PAT grants better security and is required for organizations using SSO. Learn more at https://docs.docker.com/go/access-tokens/

# 对本地镜像要打一个tag
➜  ehandbook docker tag ehandbook:v0.0.1 weimo9/ehandbook:v0.0.1
# 检查一下
➜  ehandbook docker images
REPOSITORY         TAG       IMAGE ID       CREATED          SIZE
weimo9/ehandbook   v0.0.1    df836bb667c9   19 minutes ago   136MB
ehandbook          v0.0.1    df836bb667c9   19 minutes ago   136MB
weimo9/koa-test    latest    a87090af61aa   22 months ago    117MB

直接挂梯子push

➜  ehandbook docker push weimo9/ehandbook:v0.0.1 
The push refers to repository [docker.io/weimo9/ehandbook]
5f70bf18a086: Pushed 
15111b888f32: Pushing  19.86MB
fabb6e7cc132: Retrying in 5 seconds 
46e75cb9d01b: Pushed 
525e899ff770: Pushing  69.58MB/101.1MB
