Azure-docs: Layered deployment not reapplied when base deployment changes

[jokarl]

I am using a base deployment which deploys a number of containers and configures routes on the edgeHub. Our edges have different types, and to solve that we use layers and target tags.

If I change the base deployment, the layered deployment is dropped and never reapplied, even though I can see it still targets devices:

If I deploy the exact same layer again and just increment the deployment id:

According to the documentation, my base deployment has priority 0 and should be applied to all devices in the dev environment. I then want to apply a layered deployment which also has priority 0 and should be applied on top of my base deployment.

What am I missing? It seems like the purpose of layered deployments is defeated if I cannot change the base without reapplying all layers.

Do I need a "blank" base deployment with only edgeHub and edgeAgent, and then one layered deployment for all my common containers, and then one last additional layer that depends on the type tag?

@jokarl I am enquiring on this issue. Please stay tuned for further updates.

Hello @jokarl , according to the doc:

"An IoT Edge device can apply one and only one standard automatic deployment, but it can apply multiple layered automatic deployments. Any layered deployments targeting a device must have a higher priority than the automatic deployment for that device."

Therefore, it is not supported that both the standard automatic deployment (what I believe you refer as base deployment) and layered automatic deployment have the same priority 0. Did you try adding a higher priority to the layered automatic deployment?

Thank you

Thank you @asergaz, apparently I'm just bad at reading the documentation.
