dora-rs cli client
Usage: dora <COMMAND>
Commands:
check Check if the coordinator and the daemon is running
graph Generate a visualization of the given graph using mermaid.js. Use --open to open
browser
build Run build commands provided in the given dataflow
new Generate a new project, node or operator. Choose the language between Rust,
Python, C or C++
up Spawn a coordinator and a daemon
destroy Destroy running coordinator and daemon. If some dataflows are still running, they
will be stopped first
start Start the given dataflow path. Attach a name to the running dataflow by using
--name
stop Stop the given dataflow UUID. If no id is provided, you will be able to choose
between the running dataflows
list List running dataflows
logs Show logs of a given dataflow and node
daemon Run daemon
runtime Run runtime
coordinator Run coordinator
help Print this message or the help of the given subcommand(s)
Options:
-h, --help Print help
