前言
与传统的web开发有所不同,区块链应用的测试工具还并不完善,如何在本地方便的进行联调,打通前端、后端、合约甚至graph节点的数据流,对于开发者而言是一个值得探索的路。
在我们团队中,不同的工程师使用的不同的环境,若要让架构师或者测试工程师在本地轻松的构建环境,不可避免的,我们要借助容器来实现这一目的。
docker在诸多容器中,应用广泛且工具完整,因此我们选用 docker 作为容器。
本文介绍使用了 hardhat 集成的 solidity 的合约如何在 docker 中运行。
Dockerfile
如果想把整个工程作为创建为 docker image,我们需要在根目录创建并编写 dockerfile 与 .dockerignore
Dockerfile
FROM node:16.9 as builder
WORKDIR /app
COPY package.json .
COPY yarn.lock .
RUN yarn install
FROM node:16.9
WORKDIR /app
COPY --from=builder /app/ /app/
COPY . .
EXPOSE 8545
ENTRYPOINT ["yarn"]
.dockerignore
这里注意,如果是环境是 macos ,一定要忽略 yarn.lock ,里面有一个依赖 linux 装不了。具体是哪个忘记了。

最后
可以参考菜鸟教程 https://www.runoob.com/docker/docker-hello-world.html
的相关教程,和容器进行交互。
常用指令如下:
- 创建新 image
docker build -t <image_name>:<tag> .
- 通过镜像创建并运行一个对应指令的容器
docker run -it --name <docker_name> <image_name>:<tag> <script command>
例:
docker run -it --name node dao:v1 start
