How do I get this running, what am I doing wrong?

Initially I tried running the zkValidium-quickstart demo. I played around with transaction bridging in metamask and it worked fine.
I then moved onto this codebase. I tried running the Docker-compose file in the ./test folder and I got:

Pulling cdk-validium-sequencer (cdk-validium-node:)...
ERROR: pull access denied for cdk-validium-node, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

I'm logged into my own docker-hub so I imagine this requires Polygon account permissions.
Then from ./ I tried docker build . which produced an executable but running it I get:

2023-12-14T11:57:13.575Z        FATAL   cmd/main.go:194 Required flags "cfg, network" not set
/home/azureuser/cdk-validium-node/log/log.go:140 github.com/0xPolygon/cdk-validium-node/log.appendStackTraceMaybeArgs()
/home/azureuser/cdk-validium-node/log/log.go:221 github.com/0xPolygon/cdk-validium-node/log.Fatal()
/home/azureuser/cdk-validium-node/cmd/main.go:194 main.main()
/snap/go/10455/src/runtime/proc.go:267 runtime.main()
        {"pid": 342008, "version": "v0.0.2-3-g8f4596d7"}

        /home/azureuser/cdk-validium-node/cmd/main.go:194
runtime.main
        /snap/go/10455/src/runtime/proc.go:267

so I need to add some config files. I tried building it with make build. Running ./dist/cdk-validium-node produces the same error so I'm on the right track.
I then tried passing to the executable some config files recommended in the readme and found in the /test folder:

CDK_VALIDIUM_NODE_STATEDB_HOST=cdk-validium-state-db CDK_VALIDIUM_NODE_POOL_DB_HOST=cdk-validium-pool-db ./dist/cdk-validium-node run -cfg ./test/config/debug.node.config.toml -network custom -custom-network-file ./test/config/test.genesis.config.json

which gives me the following error:

2023-12-14T13:14:35.440Z        FATAL   cmd/run.go:270  failed to connect to `host=cdk-validium-state-db user=state_user database=state_db`: hostname resolving error (lookup cdk-validium-state-db on 168.63.129.16:53: no such host)

Do I need to install a database?

How do I unblock myself here? I want to get to a point where I can locally run a chain and a rollup and test some things out.
