tried to use the same image for creating fedora instance, although i didn't get the panic, but the process gets stuck for ~15mins trying to download the pulumi aws provider:

Did you use exact same params? nested + airgap + custom memory and cpu?

Yeah I notice the aws provider...I think this is the provider from terraform. Not from pulumi.

May I can create a different issue for this, as we have 2 options now:

1. Quick one, add the provider within the Containerfile so it is not downloaded on runtime

2. [Enhancement] Migrate to aws native provider #315 (But this is a huge one). Last time not all resources were available on the native..now is GA so may now we can fully migrate.

Did you use exact same params? nested + airgap + custom memory and cpu?

yes, this is the command i ran:

 % podman run -d  --name create-fedora \
            -v ${PWD}:/workspace:z \
            -e AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID} \
            -e AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY} \
            -e AWS_DEFAULT_REGION=${AWS_DEFAULT_REGION} \
            quay.io/redhat-developer/mapt:v0.8.0-dev-linux aws fedora create \
                --project-name fedora \
                --backed-url "file:///workspace" \
                --conn-details-output "/workspace" \
                --tags project=user=anath \
                --spot \
                --airgap \
                --cpus 6 \
                --nested-virt \
                --memory 16
Trying to pull quay.io/redhat-developer/mapt:v0.8.0-dev-linux...

from the stack trace: the panic is occurring at

mapt/pkg/provider/aws/modules/spot/stack.go

Lines 137 to 138 in 57e2325

	Region: outputs["region"].Value.(string),
	AvailabilityZone: outputs["az"].Value.(string),

i think we should use the util.IfNillable() helper here

[adrianriobo]

So what would be the reason no error and outputs must be nil... Meaning there was no results for the spot request. So it should print some log (debug or error) before, even if we add the check here.

[anjannath]

this occurs when the spot price stack exists but it has no outputs which can happen if the create operation is interrupted, so if we run the following command:

 % ./out/mapt aws fedora create --spot --airgap --nested-virt --cpus 6 --memory 16 --project-name aws-mapt-fedora-test --backed-url file:///Users/anath/workspace --conn-details-output /tmp/fedora --tags user=anath
^C

stop it mid execution using Ctrl+c then re-ran the command, then we hit the panic as mentioned in this issue, we need to add a check in getOutputs() to see if the returned outputs map is empty
