Help with Update manager #353
Description
I can successfully create a new container via the Container Factory API, but when I try to update an existing container’s image using the Update Manager API over MQTT, nothing happens. The container-management service restarts the old containers but does not pull or run the new image.
Create a new nginx container (works):
mosquitto_pub -h localhost
-t "command//edge:mydevice:edge:containers/req//create"
-m '{
"topic":"edge/mydevice:edge:containers/things/live/messages/create",
"headers":{"response-required":true,"content-type":"application/json","correlation-id":"create-nginx-001"},
"path":"/features/ContainerFactory/inbox/messages/create",
"value":{"imageRef":"docker.io/library/nginx:1.27.5-alpine3.21","cmd":["nginx","-g","daemon off;"],"start":true}
}'
Verify container is running
sudo kanto-cm list
→ ID 91226b32… | nginx:1.27.5-alpine3.21 | Running
Attempt to update that container’s image (fails):
Publish desired state to Update Manager
mosquitto_pub -h localhost
-t "edge/update/desiredstate"
-m '{
"activityId":"update-nginx-to-perl-001",
"timestamp":'"$(date +%s%3N)"',
"payload":{"desiredState":{

}}

Could you please help me to publish a MQTT message to update my container ?
