Azure App Service Deploy, how to set docker ENV variables

I have a docker image that requires an ENV variable to start in the correct mode (eg. $ docker run -e "env_var_name=another_value" ...). The Dockerfile starts with:

FROM nginx:alpine
ENV env_var_name standalone

In the Azure Devops release pipeline I use AzureRmWebAppDeployment@3 to create the docker container but I do not understand where I can do the ENV settings. I cannot use the .env file. many thanks

You can add it as AppSettings to the Application Service by setting up AzureRmWebAppDeployment task in the pipeline, here is a template YAML sample:

 #11. Deploy web app
    - task: AzureRMWebAppDeployment@4
      displayName: Deploy web app on Linux container
      inputs:
        appType: webAppContainer
        DockerImageTag: ${{ parameters.image_tag }}
        DockerNamespace: ${{ parameters.registry_url }}
        DockerRepository: ${{ parameters.repository_name }}
        ...
        AppSettings: ${{ parameters.webapp_settings }}

example of webapp_settings values: webapp_settings: '-key1 "text" -key2 12 -otherKey 34'

App Settings are injected into your app as environment variables at runtime. (see here)
