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:
No special options for this server.
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:
-t
or--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.
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:
-f
or--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.
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:
-f
or--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:
-l
or--log-level
: possible values:[TRACE, DEBUG, INFO, WARN, ERROR]
, default:INFO
-v
or--verbose
: forDEBUG
,-vv
forTRACE
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
