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
