Log rotation on IoT Edge Agent - azure

Question

I am following Microsoft documentation and trying to set the logs for edge Agent through the container options. My deployment.template.json file is as follows:
{
"$schema-template": "2.0.0",
"modulesContent": {
"$edgeAgent": {
"properties.desired": {
"schemaVersion": "1.0",
"runtime": {
"type": "docker",
"settings": {
"minDockerVersion": "v1.25",
"loggingOptions": "",
"registryCredentials": {
"myRegistryName": {
"username": "$CONTAINER_REGISTRY_USERNAME",
"password": "$CONTAINER_REGISTRY_PASSWORD",
"address": "myRegistryAddress.azurecr.io"
}
}
}
},
"systemModules": {
"edgeAgent": {
"type": "docker",
"settings": {
"image": "mcr.microsoft.com/azureiotedge-agent:1.0",
"createOptions": {
"HostConfig": {
"LogConfig": {
"Type": "json-file",
"Config": {
"max-size": "10m",
"max-file": "3"
}
}
}
}
}
},
"edgeHub": {
"type": "docker",
"status": "running",
"restartPolicy": "always",
"settings": {
"image": "mcr.microsoft.com/azureiotedge-hub:1.0",
"createOptions": {
"HostConfig": {
"PortBindings": {
"5671/tcp": [
{
"HostPort": "5671"
}
],
"8883/tcp": [
{
"HostPort": "8883"
}
],
"443/tcp": [
{
"HostPort": "443"
}
]
},
"LogConfig": {
"Type": "json-file",
"Config": {
"max-size": "10m",
"max-file": "3"
}
}
}
}
}
}
},
"modules": {
"Module_Name": {
"version": "1.0",
"type": "docker",
"status": "running",
"restartPolicy": "always",
"settings": {
"image": "${MODULES.Module_Name}",
"createOptions": {
"HostConfig": {
"LogConfig": {
"Type": "json-file",
"Config": {
"max-size": "10m",
"max-file": "3"
}
}
}
}
}
}
}
}
},
"$edgeHub": {
"properties.desired": {
"schemaVersion": "1.0",
"routes": {
"route": "FROM /messages/* INTO $upstream"
},
"storeAndForwardConfiguration": {
"timeToLiveSecs": 7200
}
}
}
}
}
When I build and deploy it on my device, edge Hub and my module log rotation are applied but edgeAgent log rotation is not applied. I check the log rotation settings in the
/var/lib/docker/containers/{container_id}/hostconfig.json file.
What I have done so far:
Removed the image through sudo docker rmi sudo docker rmi mcr.microsoft.com/azureiotedge-agent:1.0 and removed all the containers including the edgeAgent container and restarted the edge environment by sudo systemctl restart iotedge. The log rotation is still not applied to the new container created by the edge run time. I am not sure, what am I missing ? Any help is appreciated. Please note, I don't want to apply log rotation by creating a daemon.json file and placing it in the edge run time folder. I need to do it through the container options specified in the deployment.template.json file.

This is a known bug where edge agent deployment does not apply if version number is identical to the one in config.yaml; please help to create a github issue for it. To workaround, please set the options in config.yaml.
