Cannot save mutiple hosts file entries under advanced network setup

[ghost]

Bug description

The UI allows me to add multiple host file entries under the advanced network setup but when I save and provision the container is only saves and applies the first host file entry and all other entries are lost.

Expected behavior

The ability to define multiple host file entries and for them to be saved to the running docker container and then displayed in the UI.

Steps to reproduce the issue:

Steps to reproduce the behavior:

1. Go to advanced network settings for an existing or new docker container
2. Add multiple host file entries
3. Deploy the container
4. Go in and edit the container
5. Only the first host file entered is displayed

Hey @ollieatseats

I'm not able to reproduce this issue, see the screenshots below:

Could you share the exact informations you're using?

I started a new container hello-world:linux and added the following two records

config.management.local:10.22.8.9
client.management.local:10.22.8.9

When the container started it only persisted the first record so I went in and added the second record again and it still did not persist it.

I am running the docker host on a fully patched Ubuntu 16.04 Azure VM (DSv2) with 18.03.1-ce installed. If you cant recreate it, its probably just my environment, it just seems strange,

I went in and added the second record again and it still did not persist it.

What do you mean by that? Did you alter the container manually?

I added the second host name via the UI again and redeployed the container and it still not add the second value.

@ollieatseats via the container creation of container edition ?

[ghost]

When I create the container I add the following host entries:

Once the container is created I then go in to edit the host entries to redeploy the container:

Ah, so this is related to container-edition ! I'll investigate.
