免费使用公有云服务

[TOC] AWS领先的设计理念和强大的技术生态 使你身陷其中,学习你要用它,开发你要 用它,上线还要用它。 一年下来项目还没有 正式商用,已经有十几万的研发费用。 今天向你推荐 localstack(与openstack啥关系?私有云+公有云), 让你使用AWS免费,至少在项目POC或开发测试阶段免费。 有了它, 你不用再焦急的等待老板审批公有云的 计算,存储,数据库资源开发申请。 是不是这个项目听起来很激动? 那如何使用localstack呢? 安装localstack localstack是一个非常活跃的正在快速成长中的项目, 建议通过源代码安装 下载源代码 git clone [email protected]:localstack/localstack.git git fetch --all git checkout tags/v0.10.3 -b v0.10.3 启用需要使用的AWS服务 修改配置文件,启用你需要使用的AWS服务:ec2,s3,iot,kafka等。 注意服务的名字必须来自服务名字列表, 否则不识别 启用服务就是修改下边的配置文件 localstack\docker-compose.yml SERVICES=${SERVICES-ec2,ecs,stepfunctions,iam,lambda,dynamodb,apigateway,s3,sns} DATA_DIR=${DATA_DIR-/tmp/localstack/data } volumes: - "${TMPDIR:-d:/tmp/localstack}:/tmp/localstack" make sure driver D is shared in docker desktop daemon docker-compose up localstack_1 | Starting mock S3 (http port 4572)... localstack_1 | Starting mock SNS (http port 4575).
