ECRにDockerイメージを登録する。
表題通り、チュートリアルを実装して行きます。
①ECRにリポジトリを作成する
→これでリポジトリが完成します！！では、次にDockerイメージを作成します。
②Dokcerイメージを作成する
FROM golang:1.17-alpine
WORKDIR /go/src/app
RUN apk update && apk add git
COPY main.go .
CMD go run main.go
main.go
package main
import "fmt"
func main() {
fmt.Println("Hello Docker")
}
Dockerイメージを作成

③ECRにDockerイメージをPushする
AWS-CLIでログインする
~/develop/go_hello_docker $aws ecr get-login-password --region ap-northeast-1 | docker login --username AWS --password-stdin XXXX.dkr.ecr.ap-northeast-1.amazonaws.com
Login Succeeded

tag付する
~/develop/go_hello_docker $ docker tag go_hello_docker:latest XXXX.dkr.ecr.ap-northeast-1.amazonaws.com/go_hello_docker:latest
ECRにイメージをPushする
~/develop/go_hello_docker $ docker push XXXXXX.dkr.ecr.ap-northeast-1.amazonaws.com/go_hello_docker:latest
The push refers to repository [XXXXXX.dkr.ecr.ap-northeast-1.amazonaws.com/go_hello_docker]
