This repository contains voltctl, a CLI tool for managing and operating VOLTHA components.
It functions similarly to the docker CLI or kubernetes kubectl CLI, in that it's a simple standalone control application which can perform various functions and has flexible and customizable output formats either as a table or JSON.
To install the voltctl command, downloads are available for multiple platforms and architectures from the github releases page, or you can compile your own copy by installing Go 1.13.x, checking out the code and running make build.
voltctl supports shell completion for the bash shell. To enable shell Completion you can use the following command on most *nix based system.
source <(voltctl completion bash)
If you are running an older bash 3.x shell (default on MacOS), then you can try the following command:
source /dev/stdin <<<"$(voltctl completion bash)"
If you which to make bash shell completion automatic when you login to your account you can append the output of voltctl completion bash to your $HOME/.bashrc:
voltctl completion base >> $HOME/.bashrc
voltctl stores it's configuration file in ~/.volt/config. An example of the configuration file can be found in the voltctl.config file in this repo.

Help specific to each command can be found by running volctl <command> -h.
Each command has a default output table format. This can be overridden from the command line using the voltctl --format=... option. The specification of the format is roughly equivalent to the docker or kubectl command. If the prefix table is specified a table with headers will be displayed, else each line will be output as specified.
The output of a command may also be written as JSON or YAML by using the --outputas or -o command line option. Valid values for this options are table, json, or yaml.
The default format and ordering of commands can be overridden (specified) by the command line options, but they can also be set via a configuration file so that the overrides don't have to be specified on each invocation.
By default the file ~/.volt/command_options is loaded, but the file used can also be specified by the environment variable VOLTCTL_COMMAND_OPTIONS or via the command line arguments.
A sample of this file is include in the repository as voltctl_command_options.config.

If you do not see packages in your output it is possible you are not retrieving the data from the correct path in ETCD. The data is stored according to the helm chart defined value for kv_store_data_prefix.
If you deployed according to the README in the voltha-helm-charts README the value for kv_store_data_prefix is service/voltha/{{ .Release.Name }}_{{ .Values.global.stack_name }}, e.g service/voltha/voltha1_voltha1.
If you are unsure about the kv_store_data_prefix you can check through one of the pods, e.g. rw-core. Make sure to use the correct namespace for -n by checking it with kubectl get pods -A and then issue:
$ kubectl describe -n voltha1 $(kubectl -n voltha1 get pods -l app=rw-core -o name) | grep KV KV_STORE_DATAPATH_PREFIX: service/voltha/voltha1_voltha1
You can set the path for any voltctl command by exporting the KV_STORE_DATAPATH_PREFIX variable, e.g. KV_STORE_DATAPATH_PREFIX=service/voltha/voltha1_voltha1.
A full example command is:
KV_STORE_DATAPATH_PREFIX=service/voltha/voltha1_voltha1 voltctl log package list adapter-open-olt
When you run VOLTHA with a high number of OLTs/ONUs is possible that the gRPC response exceeds the default 4MB in size. This will be addressed on the server side in a future release, but you have the option to exceed the allowed response size using the -m, --maxcallrecvmsgsize=SIZE option.
The common error message when this happens is:
ERROR: RESOURCEEXHAUSTED: grpc: received message larger than max (4241141 vs. 4194304)
If that happens, retry the command passing the -m option, eg:
$ voltctl device list -m 8M
