利用Amazon的弹性容器注册表作为Docker的仓库-马春杰杰

第一步、创建存储库

打开亚马逊官网，然后注册一个账号，注册是免费的，另外，弹性容器注册表可以免费使用12个月，还是很香的~

注册完成之后，打开Elastic Container Registry | ap-northeast-2 (amazon.com)，选择创建存储库：

接下来，以公有存储库为例，介绍如何使用。

设置好存储库名字之后，直接选择创建存储库即可，接下来就能看到已经创建的公有存储库：

第二步、安装Amazon CLI

接下来就是如何使用存储库。在使用之前，需要安装Amazon CLI，对于Linux来说，运行以下命令：

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

unzip awscliv2.zip

sudo ./aws/install

安装完成之后，运行/usr/local/bin/aws --version查看安装版本：

aws-cli/2.16.4 Python/3.11.8 Linux/3.10.0-1160.108.1.el7.x86_64 exe/x86_64.centos.7

然后需要配置访问凭证，首先打开安全凭证 | IAM | Global (amazon.com)，选择创建访问密钥：

保存获取到的密钥：

然后在终端输入aws configure，将上面获取到的密钥输入。

[opc@instance-20240410-1646 ~]$ aws configure
AWS Access Key ID [None]: AKIA6GBMAWOAI33
AWS Secret Access Key [None]: 7I2uz2L9gdTw4kJr1dLaSsmXWN1
Default region name [None]: us-east-1
Default output format [None]:json

[opc@instance-20240410-1646 ~]$ aws configure

AWS Access Key ID [None]: AKIA6GBMAWOAI33

AWS Secret Access Key [None]: 7I2uz2L9gdTw4kJr1dLaSsmXWN1

Default region name [None]: us-east-1

Default output format [None]:json

第三步、推送镜像

接下来，点击存储库名称，进入存储库配置界面，选择查看推送命令：

找到第一条命令，在终端上输入即可：

[opc@instance-20240410-1646 ~]$ aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/f6xxxx
WARNING! Your password will be stored unencrypted in /home/opc/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

[opc@instance-20240410-1646 ~]$ aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/f6xxxx

WARNING! Your password will be stored unencrypted in /home/opc/.docker/config.json.

Configure a credential helper to remove this warning. See

https://docs.docker.com/engine/reference/commandline/login/#credentials-store

然后，我们以自定义的Dockerfile为例，讲解如何使用存储库。首先，新建一个Dockerfile，内容为：

# 使用一个基础镜像
FROM alpine:latest

# 设置镜像作者信息
LABEL maintainer="machunjie"

# 执行打印 "Hello, World!"
CMD echo "Hello, World!"

# 使用一个基础镜像

FROM alpine:latest

# 设置镜像作者信息

LABEL maintainer="machunjie"

# 执行打印 "Hello, World!"

CMD echo "Hello, World!"

然后执行：

sudo docker build -t machunjie_docker .

[opc@instance-20240410-1646 aws_docker]$ sudo docker build -t machunjie_docker .
