# Azure WebApp Application Deployment Failures
---

This incident type refers to the failure of deployment for web applications hosted on the Azure WebApp platform. The applications fail to update due to various reasons such as incorrect configuration of deployment sources like Azure DevOps, GitHub, Bitbucket, and errors in deployment logs. The resolution of this incident is to check the logs for errors, verify the application settings, and connection strings.

### Parameters
```shell
export WEB_APP_NAME="PLACEHOLDER"

export RESOURCE_GROUP_NAME="PLACEHOLDER"

export DATABASE_CONNECTION_STRING="PLACEHOLDER"

export API_ENDPOINT="PLACEHOLDER"
```

## Debug

### List all the web apps deployed on Azure
```shell
az webapp list --query '[].name'
```

### View the deployment details for a specific web app
```shell
az webapp deployment source show --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

### Check the deployment logs for a specific web app
```shell
az webapp log tail --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

### Verify the application settings for a specific web app
```shell
az webapp config appsettings list --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

### Check the connection string for the specific web app
```shell
az webapp config connection-string list --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

## Repair

### Verify application settings: Check the application settings to ensure they are correctly configured for the WebApp environment. Verify the database connection strings, API endpoints, and other configuration settings.
```shell


#!/bin/bash



# Get the resource group and WebApp name

resource_group=${RESOURCE_GROUP_NAME}

webapp_name=${WEB_APP_NAME}



# Values to be added as key value pair

DATABASE_CONNECTION_STRING=${DATABASE_CONNECTION_STRING}

API_ENDPOINT=${API_ENDPOINT}



# Verify the application settings

az webapp config appsettings list --resource-group $resource_group --name $webapp_name



# Update the database connection string

az webapp config appsettings set --resource-group $resource_group --name $webapp_name --settings $DATABASE_CONNECTION_STRING



# Update the API endpoint

az webapp config appsettings set --resource-group $resource_group --name $webapp_name --settings $API_ENDPOINT



# Verify the updated settings

az webapp config appsettings list --resource-group $resource_group --name $webapp_name



# Retry the deployment

az webapp deployment source sync -g $resource_group -n $webapp_name
