@spinarr Hello, can you please tell me the version number of your docker-compose?
`$ docker-compose --version`
I suspect you are using docker-compose version 1.23.0 or 1.23.1, which appends hashes to containers name. This behaviour has been reverted in 1.23.2. If this is the case, can you please upgrade (or downgrade) your docker-compose and try again?

Yes. Many thanks.

Hello,
in order to connect the device to our running demo server do we need to distribute certificates to the device client?
Many thanks

For the demo server we do have a set of certificates that you need to use, it can be found [here](https://github.com/mendersoftware/mender/blob/master/support/demo.crt).
It depends a bit on how you are installing the Mender client, as these might already be installed on your device.

Great, one of our device is in demo server.
Is there a way to name devices in the image so that when they appear in dashboard we have a way to distinguish them?
Thanks.

You would typically customize the [Device identity](https://docs.mender.io/2.3/client-configuration/identity) to achieve this. Let me know if it needs additional clarifications.

Hi,
we are doing first update with our demo server and facing fail.
GW device is connected to our server.
Any pointers are much appreciated.

Is there any reason to connect to [mender.io](http://mender.io)?

In the demo example we use `s3.docker.mender.io` and `docker.mender.io` as domains for which we also provide a demo certificate for which is required by https.
To have the domains resolve correctly, you must add an entry in `/etc/hosts` on the device, e.g
```auto
192.168.1.100 s3.docker.mender.io docker.mender.io
```
Replace `192.168.1.100` above with the actual IP address of the PC running the demo server
