go docker application deployment
1. Create hello.go
//hello.go
package main
import (
"fmt"
)
func main() {
fmt.Println("Hello, World!")
}
2. Set go compilation environment
GOOS=linux //编译到linux
GOARCH=amd64 //64位,如果镜像系统是32位，则GOARCH=386
go build
3. Write Dockerfile
one: so out of large image files.
FROM golang
COPY ./hello /tmp/hello
WORKDIR /tmp/
RUN chmod +x hello
Method two: Construction minimized (recommended)
FROM alpine
COPY ./hello /tmp/hello
WORKDIR /tmp/hello
RUN chmod +x hello
ENTRYPOINT ["./hello"]
4. Construction of the mirror
docker build -t hello-image .
docker images //查看镜像
5. Run the container
docker run hello-image ./hello
