DOCKER-FOR-GO-APPLICATION-PACKAGING-AND-PUSHING-TO-DOCKER-HUB
##DOCKER COMMANDS:
(Don’t forget to navigate to the directory that contains the app and the docker file when using the Docker App):
- docker build -t go-helloworld .
- docker images
- docker run -d -p 6111:6111 go-helloworld
- docker ps
- docker tag go-helloworld rothwulf/go-helloworld:v1.0.0
- docker push rothwulf/go-helloworld:v1.0.0
IMPORTANT:
- Edit the app on this way:
package main
import (
"fmt"
"net/http"
)
func helloWorld(w http.ResponseWriter, r *http.Request){
fmt.Fprintf(w, "Hello World")
}
func main() {
http.HandleFunc("/", helloWorld)
http.ListenAndServe(":6111", nil)
}
- Edit the dockerfile on this way:
FROM golang:alpine
LABEL maintainer="Andres R. Bucheli"
WORKDIR /go/src/app
ADD . .
RUN go mod init
RUN go build -o helloworld
EXPOSE 6111
CMD ["./helloworld"]
THE LAST POINT TO TAKE INTO CONSIDERATION:
Check what IP you got for DOCKER_HOST after running the above command(default is 192.168.99.100:2376)
In browser type whatever IP you got for DOCKER_HOST along with port 5000 Ex: http://192.168.99.100:5000/
