使用docker运行一个简单的httpserver
项目源码没几行，很简单，golang1.14

Dockerfile

FROM golang:1.14 AS build
COPY . /opt/CloudNative
WORKDIR /opt/CloudNative
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o httpserver

FROM alpine
COPY --from=build /opt/CloudNative/httpserver /opt/CloudNative/httpserver
EXPOSE 8080
ENTRYPOINT ["/opt/CloudNative/httpserver"]

构建镜像脚本

#!/usr/bin/env sh
version=$(date +%Y%m%d.%H%M%S)
img=sjjwantfish/cloudnative:v$version
echo "\033[32m""$img""\033[0m"
docker build . -t $img
docker push $img

构建&运行

# 在Dockerfile目录下运行build.sh
sh build.sh  # 输出忽略
docker run -d -p 8080:8080 sjjwantfish/cloudnative:v20211019.105456

docker ps

docker inspect compassionate_brown | grep -i pid
