本文介绍了阿里云ACR入门的相关内容,包括ACR的服务特性、账号注册、实例创建以及基本操作。通过阅读本文,您可以快速了解如何使用阿里云 ACR入门并开始管理容器镜像。
阿里云容器镜像服务 (Alibaba Cloud Container Registry, 简称ACR) 是阿里云提供的容器镜像托管服务,支持Docker等格式的容器镜像和镜像仓库管理。ACR可以帮助用户安全地存储和管理容器镜像,并与阿里云的其他服务集成,方便用户在开发、测试和生产环境中快速部署应用程序。
要使用阿里云的ACR服务,首先需要注册一个阿里云账号。
注册成功后,您将收到一条短信验证码,用于验证手机号。按照提示完成验证即可。
import requests import json # 访问阿里云API注册账号的URL api_url = "https://authcenter-intl.aliyun.com/home/register" headers = { "Content-Type": "application/json" } # 注册账号的请求体 data = { "username": "your_email@example.com", "password": "your_password", "captcha": "captcha_code" } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("账号注册成功") else: print("账号注册失败", response.text)
完成阿里云账号注册后,接下来需要在阿里云控制台创建ACR实例。
示例代码:
import requests import json # 访问阿里云API创建ACR实例的URL api_url = "https://cr.console.aliyun.com/acr/instance/create" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 创建ACR实例的请求体 data = { "InstanceName": "myacr", "RegionId": "cn-hangzhou" } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("ACR实例创建成功") else: print("ACR实例创建失败", response.text)
仓库是ACR中用来管理容器镜像的集合。您可以为不同的项目或服务创建不同的仓库。
示例代码:
import requests import json # 访问阿里云API创建仓库的URL api_url = "https://cr.console.aliyun.com/acr/repositories/create" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 创建仓库的请求体 data = { "InstanceName": "myacr", "RepositoryName": "myrepo", "Public": False, "Permissions": ["pull", "push"] } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("仓库创建成功") else: print("仓库创建失败", response.text)
镜像推送是指将本地构建好的容器镜像上传到ACR仓库中,以便后续使用。
docker login
命令登录仓库。
docker login -u YOUR_USERNAME -p YOUR_PASSWORD registry.cn-hangzhou.aliyuncs.com/myacr
docker tag myimage registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
docker push
命令将镜像推送到仓库。
docker push registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
示例代码:
import requests import json import subprocess # 登录仓库 login_command = ["docker", "login", "-u", "YOUR_USERNAME", "-p", "YOUR_PASSWORD", "registry.cn-hangzhou.aliyuncs.com/myacr"] subprocess.run(login_command) # 打标签 tag_command = ["docker", "tag", "myimage", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(tag_command) # 推送镜像 push_command = ["docker", "push", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(push_command)
拉取镜像是指从ACR仓库中获取镜像并下载到本地,以便后续使用。
docker login
命令登录仓库。
docker login -u YOUR_USERNAME -p YOUR_PASSWORD registry.cn-hangzhou.aliyuncs.com/myacr
docker pull
命令从仓库中拉取镜像。
docker pull registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
示例代码:
import requests import json import subprocess # 登录仓库 login_command = ["docker", "login", "-u", "YOUR_USERNAME", "-p", "YOUR_PASSWORD", "registry.cn-hangzhou.aliyuncs.com/myacr"] subprocess.run(login_command) # 拉取镜像 pull_command = ["docker", "pull", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(pull_command)
ACR支持设置不同类型的访问权限,以确保只有具备权限的用户或服务才能访问您的镜像。
示例代码:
import requests import json # 访问阿里云API设置仓库权限的URL api_url = "https://cr.console.aliyun.com/acr/repositories/permissions/update" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 设置仓库权限的请求体 data = { "InstanceName": "myacr", "RepositoryName": "myrepo", "Permissions": ["pull"] } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("仓库权限设置成功") else: print("仓库权限设置失败", response.text)
ACR支持使用多种凭证(如访问密钥、凭据等)来访问和管理仓库。凭证可以帮助您更安全地管理访问权限。
示例代码:
import requests import json # 访问阿里云API获取凭证的URL api_url = "https://cr.console.aliyun.com/acr/credentials/create" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 创建凭证的请求体 data = { "InstanceName": "myacr", "CredentialType": "accessKey" } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("凭证创建成功") else: print("凭证创建失败", response.text)
镜像签名是一种确保容器镜像来源可信、未被篡改的技术手段。通过签名,您可以验证镜像的真实性和完整性。
docker sign
命令签署镜像。
docker sign registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
docker push
命令推送签名后的镜像。
docker push registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
docker verify
命令验证镜像签名。
docker verify registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest
示例代码:
import subprocess # 签署镜像 sign_command = ["docker", "sign", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(sign_command) # 推送签名后的镜像 push_command = ["docker", "push", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(push_command) # 验证签名 verify_command = ["docker", "verify", "registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest"] subprocess.run(verify_command)
ACR可以与阿里云的容器服务(如容器服务Kubernetes版、容器服务企业版等)无缝集成,简化应用的部署流程。
示例代码:
import requests import json # 访问阿里云API绑定ACR实例的URL api_url = "https://cr.console.aliyun.com/acr/instances/bind" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 绑定ACR实例的请求体 data = { "InstanceName": "myacr", "ServiceName": "myk8s" } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("ACR实例绑定成功") else: print("ACR实例绑定失败", response.text)
ACR可以与阿里云的CI/CD(持续集成/持续部署)服务集成,实现自动化构建和部署。
示例代码:
import requests import json # 访问阿里云API配置构建任务的URL api_url = "https://cr.console.aliyun.com/cicd/buildtasks/create" headers = { "Content-Type": "application/json", "Authorization": "Bearer YOUR_ACCESS_TOKEN" } # 配置构建任务的请求体 data = { "PipelineId": "mypipeline", "BuildType": "docker", "BuildCommand": "docker build -t registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest .", "PushCommand": "docker push registry.cn-hangzhou.aliyuncs.com/myacr/myrepo:latest" } response = requests.post(api_url, headers=headers, data=json.dumps(data)) # 检查请求是否成功 if response.status_code == 200: print("构建任务配置成功") else: print("构建任务配置失败", response.text)
在使用ACR过程中可能会遇到一些常见错误,以下是部分常见错误及解决方案。

ACR的费用及计费方式如下:
阿里云经常会有各种优惠活动,包括新用户优惠、包年包月折扣等。您可以在阿里云官网查看最新的优惠信息。
假设您存储了1GB的镜像,并在一个月内拉取或推送了10GB的网络流量,则您的费用可能如下:
示例代码:
def calculate_cost(storage_gb, traffic_gb): storage_price = 0.01 # 存储单价,单位:元/GB traffic_price = 0.001 # 流量单价,单位:元/GB storage_cost = storage_gb * storage_price traffic_cost = traffic_gb * traffic_price total_cost = storage_cost + traffic_cost return total_cost # 示例计算 storage_gb = 1 traffic_gb = 10 total_cost = calculate_cost(storage_gb, traffic_gb) print(f"总费用: {total_cost} 元")
通过以上介绍,您应该对阿里云的ACR服务有了更深入的了解。ACR提供了丰富的功能和灵活的计费方式,帮助您高效管理和部署容器镜像。希望您能够充分利用ACR提供的各种功能,提高开发和部署效率。如果您有任何疑问或需要进一步的帮助,请随时咨询阿里云的技术支持团队。
