graalvm 23.1.0 独立nodejs docker 镜像&简单试用
graaljs docker 镜像
很简单就是下载官方包，集成下，然后进行一些简单的配置
- Dockerfile
FROM debian:bullseye-backports
LABEL author="rongfengliang"
LABEL email="1141591465@qq.com"
WORKDIR /opt/
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo 'Asia/Shanghai' >/etc/timezone
COPY graalnodejs-23.1.0-linux-amd64/ /opt/nodejs/
ENV PATH=/opt/nodejs/bin:$PATH
参考项目
- package.json
{
"name": "graaljs-learning",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"build": "ncc build index.js -o dist"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"fastify": "^4.23.2",
"hashids": "^2.3.0"
},
"devDependencies": {
"@vercel/ncc": "^0.38.0"
}
}
- index.js
const hashids = require('hashids')
const myid = new hashids('this is my salt', 10, 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890')
const Fastify = require('fastify')
const fastify = Fastify()
fastify.get('/', async (request, reply) => {
console.log(myid.encode(1, 2, 3))
reply.send({ hello: myid.encode(1, 2, 3) })
})
fastify.listen({
port: 3000,
host: "0.0.0.0",
backlog: 511
}, (err, address) => {
if (err) {
console.error(err)
process.exit(1)
}
console.log(`Server listening at ${address}`)
})
- 构建
yarn build
- docker-compose 文件
version: '3'
services:
app:
image: dalongrong/graaljs:23.1.0
command: node --jvm --polyglot /app/index.js
ports:
- "3000:3000"
volumes:
- ./dist:/app/
- 效果
说明
docker 镜像我已经push dockerhub了 dalongrong/graaljs:23.1.0 目前来说独立的graaljs 的确会简化node 与jvm 项目的集成，当然从实际测试来说graaljs 暂时还是不如nodejs 项目启动快速,但是对于业务有node 与java 互调用的场景是一个特别好的选择，比基于node-addon 的模式很很多
