azdWhen a project uses a built-in service host, run `azd deploy --preview` to ask each selected service target to describe deployment changes. Read the human-readable `Message` in text output or `services.<name>.data` with JSON output.
azd deploy --previewWhen tuning parallel work in an azd project, set the relevant concurrency environment variables for `azd up`, `azd deploy`, or `azd provision`. Configure `AZD_CONCURRENCY_MAX` for the global ceiling; values are clamped to 64, and standalone `azd package` remains sequential.
AZD_PACKAGE_CONCURRENCY=<positive-integer> AZD_PROVISION_CONCURRENCY=<positive-integer> AZD_DEPLOY_CONCURRENCY=<positive-integer> AZD_CONCURRENCY_MAX=<positive-integer> azd upWhen deploying an existing remote image by reference, set `services.<name>.docker.imagePassthrough: true` and set the service-level `image` to its fully qualified registry reference, then run `azd deploy <service>`.
azd deploy <service>When the extension bundle is self-contained and hosted at an HTTPS URL, pass that URL as the extension name to `azd extension install`.
azd extension install https://<host>/<path>/<bundle>.zipWhen you want to install only a named extension, run `azd extension install` with `--no-dependencies` to skip its declared dependencies.
azd extension install <extension-id> --no-dependenciesWhen deploying a Docker-based service to App Service, set `host: appservice` and `language: docker` or `docker.path`. Then run `azd deploy <service>` to build and push the image to ACR and update the site’s container image reference.
services:
<service>:
project: ./src/web
host: appservice
language: docker
docker:
path: ./DockerfileWhen installing or upgrading an extension from a registry URL or local path, pass that location with `--source` to register and use it. The current docs describe `list --source` as read-only; see conflicts.
azd extension install <extension-id> --source <registry-url-or-local-path>When interactive subscription prompts should show only selected subscriptions for a tenant, run `azd config sub-filter set` and select the subscriptions to include. Run `azd config sub-filter remove` to clear that tenant’s filter and show all subscriptions in prompts.
azd config sub-filter setWhen deploying a Go Function App on Flex Consumption, run `azd up` from the project template folder. The command packages, provisions, and deploys the project.
azd upWhen a program or script needs the current azd environment context, run it with `azd exec`; the documented syntax supplies azd environment variables to the child process. The 1.25.1 release note also says this includes Key Vault secret resolution.
azd exec <program> [args...]
