Trouble Running Iris using Docker in Linux

Hi all, I am having problems trying to get Docker to run correctly on my Linux Mint machine.

I did the following:

1. Installed Docker.


docker --version

Docker version 19.03.6, build 369ce74a3c

docker-compose -v

docker-compose version 1.17.1, build unknown

2. Downloaded zip from

and unzipped it

3. Entered the following command:

docker-compose up -d

This generated the following error:

ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see

Following the suggestion in the error message,  I modified docker-compose.yml, changing version "3.6" to version "3.3"

docker-compose up -d

That still failed:

root      1701     1  0 09:19 ?        00:00:03 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
marlin   11391 11244  0 10:32 ?        00:00:00 /usr/share/code/code /home/marlin/.vscode/extensions/ms-azuretools.vscode-docker-1.6.0/dist/dockerfile-language-server-nodejs/lib/server.js --node-ipc --node-ipc --clientProcessId=11244

Any suggestion on what to do to get it working?  Thanks!

Update compose to to the latest version (docs) and try to run original docker-compose.yml (with 3.6).
