DV alone with CLI - docker run command missing flags

[KaloyanTanev]

🎯 Problem to be solved

While trying to launch a cluster alone following the CLI in the docs, it didn't seem as streamlined as I hoped for.

In step 1.2 there is code snippet that I don't quite get:

WITHDRAWAL_ADDR=[ENTER YOUR WITHDRAWAL ADDRESS HERE]
FEE_RECIPIENT_ADDR=[ENTER YOUR FEE RECIPIENT ADDRESS HERE]
NETWORK="holesky"

Those values are not exported, neither do they exist in the .env.

Furthermore in step 1.4 the command:

docker run --rm -v "$(pwd):/opt/charon" --env-file .env obolnetwork/charon:v0.19.0 create cluster

returns:

20:43:32.172 ERRO cmd        Fatal error: missing --nodes flag       
	cmd/createcluster.go:310 .validateCreateConfig
	cmd/createcluster.go:145 .runCreateCluster
	cmd/createcluster.go:91 .func1
	cmd/cmd.go:80 .func1
	main.go:19 .main

while I do understand (after diving into the charon code) that there should be either --nodes flag or --definition-file, from where they are fetched, I believe it should be a bit more clear for the user what to do, with the example code snippets running out of the box.

🛠️ Proposed solution

1. Remove

WITHDRAWAL_ADDR=[ENTER YOUR WITHDRAWAL ADDRESS HERE]
FEE_RECIPIENT_ADDR=[ENTER YOUR FEE RECIPIENT ADDRESS HERE]
NETWORK="holesky"

if it is not required.

2. Add the necessary flags to the docker run --rm -v "$(pwd):/opt/charon" --env-file .env obolnetwork/charon:v0.19.0 create cluster command so the user can see what is the bare minimum config required to run. Potentially again with similar [ENTER YOUR WITHDRAWAL ADDRESS HERE] values where necessary.

Or

Add example definition file that the user can use and pass to the docker run --rm -v "$(pwd):/opt/charon" --env-file .env obolnetwork/charon:v0.19.0 create cluster command. Potentially again with similar [ENTER YOUR WITHDRAWAL ADDRESS HERE] values where necessary.

🧪 Tests

Be able to seamlessly follow the instructions 1:1 for running cluster alone via the CLI.
