建立一個簡單的Go網路應用程式，建置並部署為AWS ECR image。
事前要求
參考「Mac Homebrew 安裝 AWS CLI」安裝AWS CLI。
參考「AWS ECR 建立private repository」建立ECR private repositroy，名稱為ecr-1。
參考「Golang 建立網頁伺服器 Web Server」建立Go網路應用程式。
參考「Go 建立docker image」在應用程式專案根目錄下建立Dockerfile（不需要build image）。
Build image
在專案根目錄下以命令列執行docker build --platform linux/amd64 -t go-image:test .來使用Dockerfile來建立image，名稱為go-image。
~/../go-demo% docker build --platform linux/amd64 -t go-image:test .

輸入docker images檢視建立的image如下。

部署image到ECR repository
例如要部署的ECR private repository的URI為123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1。
Docker登入ECR private repository，輸入aws ecr get-login-password --region ap-northeast-1 | docker login --username AWS --password-stdin 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com。123456789012替換成你的AWS帳戶號碼，ap-northeast-1替換為ECR repository所在的region。
~% aws ecr get-login-password --region ap-northeast-1 | docker login --username AWS --password-stdin 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com
Login Succeeded
輸入docker tag go-image:test 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest將go-demo:test image標籤為123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest。
~% docker tag go-image:test 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest
輸入docker images檢視標記的image如下。

輸入docker push 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest將123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest標記的image推送到ECR repository。
~% docker push 123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1:latest
The push refers to repository [123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/ecr-1]

測試
在AWS console，前往ECR repository檢視上傳的image。。
