Deleting a resource​

The best way to delete a resource cleanly is to delete the resource group associated with that resource:

  1. Go to Resource groups

  2. Click the menu icon to the right of the resource group you'd like to delete > Delete resource group

App Service​

Build process​

The build process is run by Oryx

Oryx will build the application based on the detected language. See its documentation on how it detects and builds languages.

Deployment process​

The deployment process is run by kudu

Deploying Java apps using Local Git​

Local Git isn't officially supported for Java apps. To get it working:

  1. Create a .deployment file with this content:

    [config]
    command = bash deployment.sh

  2. Create a deployment.sh file with this content:

    # Echo all commands in this script
    set -x

    # Install Java (the Azure App Service build runs using https://github.com/microsoft/Oryx)
    /opt/oryx/oryx prep -s "$DEPLOYMENT_SOURCE" 2>&1

    # Gradle needs to know where Java is
    export JAVA_HOME=$(ls -d /tmp/oryx/platforms/java/*)

    # Clean any previous builds and build the jar file
    ./gradlew clean bootJar 2>&1

    # Get the path to the app jar file
    APP_JAR=$(find build/ -name "*.jar" -not -name "*-plain.jar")

    # Copy the app jar file to /home/site/wwwroot/app.jar which will be run by default
    # (https://github.com/Azure-App-Service/java/blob/dbba8f05c433df825a06d7a27bbf5060b1c4d812/shared/init_container.sh#L146)
    cp "${DEPLOYMENT_SOURCE}/${APP_JAR}" "${DEPLOYMENT_TARGET}/app.jar"

    Customize as needed, e.g. for Maven you might use this instead:

    ./mvnw clean package 2>&1
    APP_JAR=$(find target/ -name "*.jar" -not -name "*-plain.jar")

    You can also use the built-in Oryx build logic for Java by replacing the oryx line with this:

    /opt/oryx/oryx build --platform java --output "$DEPLOYMENT_TARGET" "$DEPLOYMENT_SOURCE" 2>&1

    However, it seems to run mvn clean compile so you'll still need to run mvn clean package manually in order to generate the .jar file.

Web apps​

Create a new web app from a Github repo​

  1. Create a resource

  2. Web > Web App

    • Note: Don't choose Web App for Containers. This will only allow you to deploy your app by creating and updating a container for the app itself

  3. Once the app resource has been created, go to Deployment > Deployment options to set up a repository for automated deployments

  4. Define any environment variables as desired (see below)

Set environment variables​

  1. Settings > Application settings > Application settings

  2. Make sure to click Save when you're done

Monitoring web app deployments from Github​

Go to Deployment > Deployment options

SSH into web app container instance​

https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-ssh-support#open-ssh-session-from-remote-shell

View logs​

  1. Enable logging

    1. Monitoring > Diagnostics logs

    2. Docker Container logging > change it to something other than Off

    3. Save

  2. SSH into the container instance (see above)

  3. Logs will be located in /home/LogFiles

    • The log naming is inconsistent, but the log you want will be one of the more recent ones and should grow in size

VMs​

Restrict access to a VM​

  1. Settings > Networking

  2. Under Inbound port rules click on the specific entry you'd like to restrict

  3. Change the Source as desired > Save
