Add Container Apps environment conflict pre-deployment check to azure-deploy by Copilot · Pull Request #1746 · microsoft/GitHub-Copilot-for-Azure

Copilot · 2026-04-07T16:02:08Z

azd up silently resolves existing Container Apps environment conflicts by creating a new environment (e.g. "deployment-prod"), causing unexpectedly long deployments and test timeouts.

Changes

pre-deploy-checklist.md — New mandatory Step 5a for Container Apps deployments: run az containerapp env list against the target resource group before azd up. If existing environments are found, surface them via ask_user with three resolution paths:
1. Select the matching AZD env to reuse the existing environment (recommended)
2. Create a new env with a unique name targeting a clean resource group
3. Delete the conflicting environment (destructive; requires user confirmation per global-rules)
pre-deploy-checklist.md — Added Skipping Container Apps environment check to the Common Mistakes table
SKILL.md — Version bumped 1.0.15 → 1.0.17

Example check

az containerapp env list \
  --resource-group rg-<env-name> \
  --query "[].{name:name, location:location, provisioningState:properties.provisioningState}" \
  -o table

Pull request overview

Adds a pre-deployment safeguard to prevent azd up from silently creating a new (unexpectedly named) Container Apps environment when one already exists in the target resource group, reducing long deployments and timeout risk.

Changes:

Adds a new mandatory “Step 5a” to detect existing Container Apps environments in the target RG and guide user resolution via ask_user.
Updates the “Common Mistakes to Avoid” table to include skipping the Container Apps environment check.
Bumps azure-deploy skill version to 1.0.16.

The new Common Mistakes row uses rg-<env> while the new Step 5a section uses rg-<env-name> (and Step 4 uses rg-<environment-name>). Please align this row’s placeholder with the convention used in the checklist steps so readers can copy/paste without guessing.

| Assuming location without checking RG | Check `az group show` before choosing |
| Ignoring tag conflicts in target RG | Check `az resource list --resource-group rg-<env>` before deploy |
| Skipping Container Apps environment check | Run `az containerapp env list --resource-group rg-<env>` before deploy (Step 5a) |

Adds a pre-deployment checklist guardrail to detect and resolve Azure Container Apps environment name/resource-group conflicts before running azd up, helping prevent silent creation of unexpected Container Apps environments that can prolong deployments and cause drift/timeouts.

Changes:

Introduces a new mandatory “Step 5a” in the azure-deploy pre-deploy checklist to list existing Container Apps environments in the target resource group and prompt the user with resolution options.
Extends the “Common Mistakes to Avoid” table with a reminder to run the Container Apps environment check.

plugin/skills/azure-deploy/references/pre-deploy-checklist.md:226

The new Common Mistakes row suggests running az containerapp env list --resource-group rg-<env> unconditionally. Since Step 5a explicitly gates this check on the resource group already existing (Step 4), consider reflecting that in the table entry (e.g., "If rg-<env> exists, run...") to avoid reintroducing the earlier "RG not found" failure mode.

| Running `azd up` without environment | `azd env new <name>` first |
| Assuming location without checking RG | Check `az group show` before choosing |
| Ignoring tag conflicts in target RG | Check `az resource list --resource-group rg-<env>` before deploy |
| Skipping Container Apps environment check | Run `az containerapp env list --resource-group rg-<env>` before deploy (Step 5a) |
