How can I assign random ports to a cni network and read these back from
srv. What is the equivalent of portDefinitions at network/host for
network/container?

Subject: health check not working after changing host network
If I change a task from:
"networks": [
{ "mode": "host" }
],
"portDefinitions": [
{"port": 0, "name": "health", "protocol": "tcp"},
{"port": 0, "name": "metrics", "protocol": "tcp"}
],
To:
"networks": [
{ "mode": "container", "name": "cni-storage" }
],
"portDefinitions": [
{"port": 0, "name": "health", "protocol": "tcp"},
{"port": 0, "name": "metrics", "protocol": "tcp"}
],
I am getting this error:

What am I doing wrong?
