【Azure App Service】本地Git部署Python Flask应用上云(Azure App Service For Linux)关键错误

简介: 【Azure App Service】本地Git部署Python Flask应用上云(Azure App Service For Linux)关键错误

问题描述

Python Flash应用上云,本地Git部署(https://docs.azure.cn/zh-cn/app-service/quickstart-python?tabs=flask%2Cwindows%2Cazure-cli%2Clocal-git-deploy%2Cdeploy-instructions-azportal%2Cterminal-bash%2Cdeploy-instructions-zip-azcli),遇见两类问题。

1: src refspec master does not match any

> git push azure master

error: src refspec master does not match any

error: failed to push some refs to 'https://xxxxxxxxx.scm.chinacloudsites.cn:443/xxxxxxxxx.git'

2:remote: Error - Changes committed to remote repository but deployment to website failed.

问题解答

面对问题,反复尝试。

继续使用 " git push azure master " " git push azure main " 指令push本地文件到App Service, 但总是显示 error : xxxx 或 Everything up-to-date 。 根本无法完成App Service的部署操作。

对比文档,对有默认的 master  branch变换为main,检查官方文档中,需要设置DEPLOYMENT_BRANCH参数,并设置为 main。

应用服务的默认部署分支是 master,但许多 Git 存储库将从 master 移至 main。 可以在推送中指定本地分支名称和远程分支名称之间的对应关系(如下所示),也可以配置 DEPLOYMENT_BRANCH 应用设置

配置完成后,通过对本地文件修改,使得 push 时不再是 everything up-to-date。

# 添加修改的内容

git add  .

# 提交修改到本地 Ropes

git commit -m "update"

# Push到App Service Repostory

git push azure main

此次,输出内容完成,并明确提示Deployment successful。

PS C:\MyWorkPlace\CaseFile\CASE\msdocs-python-flask-webapp-quickstart> git push azure main
Everything up-to-date
PS C:\MyWorkPlace\CaseFile\CASE\msdocs-python-flask-webapp-quickstart> git add  .
