Hey Folks, beginner here. I'm getting the following error: sudo fleetctl preview Downloading dependencies into /root/.fleet/preview... Pulling Docker dependencies... Invalid interpolation format for “fleet01” option in service “services”: “fleetdm/fleet:${FLEET_VERSION:-latest}”

What version of docker & docker compose are you running?

Hi Ben: docker v. 20.10.8 docker-compose v. 1.25.0

I am on Ubuntu, and just pulled main. Docker:

Docker version 20.10.7, build f0df35096d

Docker Compose

docker-compose version 1.29.2

and running `fleetctl preview`:

fleetctl preview
Downloading dependencies into /home/ben/.fleet/preview...
Pulling Docker dependencies...

Waiting for server to start up...

Fleet UI is now available at <http://localhost:1337>.

Preview environment complete. Enjoy using Fleet!

Invalid interpolation format seems like a Docker issue. This command pulls down https://github.com/fleetdm/osquery-in-a-box and combines the docker compose files there to start up all the dependencies and the local environment. Seems odd to me that there isn't a

version

declaration in https://github.com/fleetdm/osquery-in-a-box/blob/master/docker-compose.yml which I suspect might be an issue for the version of compose you are running.

Hey Benjamin -- I'll give that a go today (this morning EST) and let you know.

Glad I could help
