通过golang实现一个简单的镜像下载工具
总体步骤
启动一台海外区域的ec2实例安装docker和awscli配置凭证访问国内ecr仓库编写web服务实现镜像转换和自动推送
安装docker和awscli
sudo yum remove awscli -y
sudo yum install less -y
sudo yum install unzip -y
curl https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip -o awscliv2.zip
unzip awscliv2.zip
sudo ./aws/install --update
complete -C /usr/local/bin/aws_completer aws
sudo yum install docker -y
sudo systemctl start docker
sudo systemctl enable docker
sudo groupadd docker
sudo usermod -aG docker ec2-user配置ecr凭证助手 https://github.com/awslabs/amazon-ecr-credential-helper sudo yum install amazon-ecr-credential-helper
vim ~/.docker/config.json
{credsStore: ecr-login
}或者手动临时配置凭证
aws ecr get-login-password --region cn-north-1 | docker login --username AWS --password-stdin xxxxxx.dkr.ecr.cn-north-1.amazonaws.com.cn编写web服务
使用golang原生的http包实现比较简单粗糙测试用的话足够了
