Description
According to the API documentation, the container Config field is meant to indicate portable configuration between hosts, however, since v25, this field will include the dynamically generated Mac address, which doesn't seem to fit the definition of portable.
This also means that the Config field no longer reflects the configuration options passed to docker run, e.g.
docker network create my-network
# Config.MacAddress should be null for this container
docker run --rm -d --name test --network my-default --mac-address "" alpine sleep infinity
Reproduce
docker network create my-network
docker run --rm -d --name test --network my-default --mac-address "" alpine sleep infinity
# Output: "02:42:ac:13:00:02"
docker inspect test | jq .[].Config.MacAddress
Expected behavior
docker network create my-network
docker run --rm -d --name test --network my-default --mac-address "" alpine sleep infinity
# Output: null
docker inspect test | jq .[].Config.MacAddress
This is the behavior on v24
