# todo: better handling for input parameters.  Argbash?
# todo: skip storage volume init if deploying to a remote / cloud cluster (ICP IKS ROKS etc...)
# todo: for logging, set up a stack and allow multi-line status output codes
# todo: user:pass auth for tls and ecert bootstrap admins.  here and in the server-config.yaml
# todo: refactor chaincode install to support other chaincode routines
# todo: allow the user to specify the chaincode name (hardcoded as 'basic') both in install and invoke/query
# todo: track down a nasty bug whereby the CA service endpoints (kube services) will occasionally reject TCP connections after network down/up.  This is patched by introducing a 10s sleep after the deployments are up...

# todo: allow relative paths for input arguments.
