Kestra server command
Kestra leverages five different server components. The kestra server command allows to start them one by one, or run an all-inclusive standalone server.
Separate server components
Kestra Executor
./kestra server executor
Options:
--skip-executions: the list of execution identifiers to skip. Use it only for troubleshooting e.g. when an execution cannot be processed by Kestra.
Kestra Indexer
./kestra server indexer
Options:
No special options for this server.
Kestra Scheduler
./kestra server scheduler
Options:
No special options for this server.
Kestra Worker
./kestra server worker
Options:
-tor--thread: the number of threads that can handle tasks at the same time. By default, the worker will start 2 threads per CPU core available.-gor--worker-group: the key of the worker group if using Worker Group (EE).
Kestra Webserver
./kestra server webserver
Options:
No special options for this server.
Kestra standalone, all server components in one process
./kestra server standalone
This server is a special server, since it will contain all the server components in one JVM. This works well for development or small-sized environments.
Options:
-for--flow-path: the path to a directory with YAML flow files. These files will be loaded to the repository at startup.--worker-thread: the number of worker threads. By default, the embedded worker will start 3 threads or a single thread per CPU core when more than 3 CPU cores are available.--skip-executions: the list of execution identifiers to skip. Use it only for troubleshooting e.g. when an execution cannot be processed by Kestra.
Kestra local, development server with no dependencies
./kestra server local
This server is a local development server. It will contain all the servers in one JVM, and use a local database (H2), and local storage - perfect to start a development server. All the data will be saved in a data directory on the current working directory.
Options:
-for--flow-path: the path to a directory with YAML flow files. These files will be loaded to the repository at startup.--worker-thread: the number of worker threads. By default, the embedded worker will start 3 threads or a single thread per CPU core when more than 3 CPU cores are available.
Options for all server commands
Log Level
Log level can be changed with two options:
-lor--log-level: possible values:[TRACE, DEBUG, INFO, WARN, ERROR], default:INFO-vor--verbose: forDEBUG,-vvforTRACE
These options affect global log levels for all flows only.
Internal Log
--internal-log: Kestra hides internal logs by default. Use this option to enable these logs.
This option enables logs of very high verbosity.
Configuration Files
-c or --config: You can change the location of Kestra configuration files, the default is ~/.kestra/config.yml.
Plugins directory
-p or --plugins: Path to the plugins directory. The default is the plugins directory located in the same directory as the Kestra executable.
Server port
--port: The server port, the default is 8080.
