Cannot connect to the Docker in Cloud Shell

[v-hongli1]

Describe the issue: Can't start the docker in Cloud Shell.

Repro Steps:

1. Login to Azure Portal
2. Open Cloud Shell terminal
3. Installation: to install run “mkdir -b ~/bin && curl -fsSL https://aka.ms/install-azd.sh | bash -s -- --install-folder ~/bin”
4. Create a folder for test templates
5. Run command azd init -t <template>
6. Run command azd up

Error Message:

Error Trace: After investigation, docker needs to be started, but we are neither the root user nor do we know the root password, so we can't start docker.

Environment: OS: Cloud Shell Template:

• https://github.com/Azure-Samples/todo-nodejs-mongo-aca
• https://github.com/Azure-Samples/todo-python-mongo-aca

Azd version: 0.4.0-beta.1 (commit 2bf7a529914d86d8e9f5d7b6f95a4f20a2351e01)

Expected behavior: The docker service can successfully start.

@danieljurek for notification.

@danieljurek should we reach-out to the Cloud Shell team on this for making our ACA templates work in Cloud Shell?

[danieljurek]

Possible solution... use an ACR task to build in the ACR instance. https://learn.microsoft.com/en-us/azure/container-registry/container-registry-tasks-overview#quick-task

Docker daemon on the host is not supported in Cloud Shell currently: https://learn.microsoft.com/en-us/azure/cloud-shell/troubleshooting#you-cant-run-the-docker-daemon

Recommendation is to do actions which require the docker daemon (e.g. docker build) on another host.

Thanks for finding out more Daniel.

@savannahostrowski @puicchan @jongio If Cloud Shell doesn't natively support what we want. Instead of circumventing and making it work. Should we callout saying ACA templates are not supported form Cloud Shell?

[savannahostrowski]

Pinged the Cosmos team to check in on if there are particular scenarios they are targeting, which might help inform our path forward.

I think we can proceed and document this as a known limitation for now. I'll mark as docs, cc: @gkulin

Should be added to doc in the release which contains CloudShell support in Azd. Currently it is blocked with the JDK upgrade #1207
