The goal is to use the az iot edge deployment update command to change a module in an azure iot hub/edge deployment. The attempt to do this uses the property-path within the deployment configuration json to replace the image path. The problem is that there is a dot in a json property properties.desired and attempts of escaping it have been futile. The file is a default azure deployment configuration file.
Command format
az iot edge deployment update --deployment-id <name-of-deployment> --hub-name <name-of-iot-hub> --set <json-path>=<new-value>
First part of the deployment configuration (json)
The goal is to change the value of image
{
"content": {
"modulesContent": {
"$edgeAgent": {
"properties.desired": {
"modules": {
"demoimage1-latest": {
"settings": {
"image": "demoworkspac2478a907.azurecr.io/demoimage1:6",
The most obvious attempt
az iot edge deployment update --deployment-id demoimage1-6 --hub-name iot-hubski --set content.modulesContent.'$edgeAgent'.'properties.desired'.modules.'demoimage1-latest'.settings.image=demoworkspac2478a907.azurecr.io/demoimage1:5
Gives
Couldn't find 'properties' in 'content.modulesContent.$edgeAgent.properties.desired.modules.demoimage1-latest'. Available options: ['properties.desired']
Status
Many things have been tried using both bash (ubuntu LTS vm) and powershell (win10)
[properties.desired]'[properties.desired]'['properties.desired']properties\.desiredproperties.desired`properties.desired'..."properties.desired"...''...\"properties.desired\"...''$edgeAgent'[properties.desired]'$edgeAgent'['properties.desired']^[properties.desired^]^^[properties.desired^^]]you need to manually strinigying the $edgeHub JSON.
az iot edge deployment update --deployment-id testedge --hub-name microwaves --set content.modulesContent.'$edgeHub'="{'properties.desired': {'routes': {'route': 'FROM /messages/* INTO $upstream'},'schemaVersion': '1.0','storeAndForwardConfiguration': {'timeToLiveSecs': 7201}}}"
However it doesn't do anything because of content being immutable. Items that can be updated by az iot edge deployment update command: labels, metrics, priority and targetCondition. labels and metrics do not allow values with ‘.’ in the name.
