YESJBangs commands to run.
YESAUTOLINUXWINDOWSAUTOThe target operating system where the script will run.
YESA list of commands that will run before the commands, allowing to set up the environment e.g. pip install -r requirements.txt.
YESjbangdev/jbang-actionThe task runner container image, only used if the task runner is container-based.
NODeprecated - use the 'taskRunner' property instead.
Only used if the taskRunner property is not set
YESAdditional environment variables for the current process.
YEStrueYESThe files to create on the local filesystem. It can be a map or a JSON object.
YES["/bin/sh","-c"]Which interpreter to use.
NOInject namespace files.
Inject namespace files to this task. When enabled, it will, by default, load all namespace files into the working directory. However, you can use the include or exclude properties to limit which namespace files will be injected.
YESfalseYESThe files from the local filesystem to send to Kestra's internal storage.
Must be a list of glob expressions relative to the current working directory, some examples: my-dir/**, my-dir/*/** or my-dir/my-file.txt.
NOPROCESSDOCKERDeprecated - use the 'taskRunner' property instead.
Only used if the taskRunner property is not set
NO{
"type": "io.kestra.plugin.scripts.runner.docker.Docker"
}The task runner to use.
Task runners are provided by plugins, each have their own properties.
YEStrue0The exit code of the entire flow execution.
The output files' URIs in Kestra's internal storage.
The value extracted from the output of the executed commands.
YEStrueYESA list of filters to exclude matching glob patterns. This allows you to exclude a subset of the Namespace Files from being downloaded at runtime. You can combine this property together with include to only inject a subset of files that you need into the task's working directory.
YESA list of filters to include only matching glob patterns. This allows you to only load a subset of the Namespace Files into the working directory.
YESYESThe maximum amount of kernel memory the container can use.
The minimum allowed value is 4MB. Because kernel memory cannot be swapped out, a container which is starved of kernel memory may block host machine resources, which can have side effects on the host machine and on other containers. See the kernel-memory docs for more details.
YESThe maximum amount of memory resources the container can use.
Make sure to use the format number + unit (regardless of the case) without any spaces.
The unit can be KB (kilobytes), MB (megabytes), GB (gigabytes), etc.
Given that it's case-insensitive, the following values are equivalent:
"512MB""512Mb""512mb""512000KB""0.5GB"
It is recommended that you allocate at least 6MB.
YESAllows you to specify a soft limit smaller than memory which is activated when Docker detects contention or low memory on the host machine.
If you use memoryReservation, it must be set lower than memory for it to take precedence. Because it is a soft limit, it does not guarantee that the container doesn’t exceed the limit.
YESThe total amount of memory and swap that can be used by a container.
If memory and memorySwap are set to the same value, this prevents containers from using any swap. This is because memorySwap includes both the physical memory and swap space, while memory is only the amount of physical memory that can be used.
YESA setting which controls the likelihood of the kernel to swap memory pages.
By default, the host kernel can swap out a percentage of anonymous pages used by a container. You can set memorySwappiness to a value between 0 and 100 to tune this percentage.
YESYES1Docker image to use.
YESDocker configuration file.
Docker configuration file that can set access credentials to private container registries. Usually located in ~/.docker/config.json.
NOLimits the CPU usage to a given maximum threshold value.
By default, each container’s access to the host machine’s CPU cycles is unlimited. You can set various constraints to limit a given container’s access to the host machine’s CPU cycles.
YESYESDocker entrypoint to use.
YESExtra hostname mappings to the container network interface configuration.
YESDocker API URI.
NOLimits memory usage to a given maximum threshold value.
Docker can enforce hard memory limits, which allow the container to use no more than a given amount of user or system memory, or soft limits, which allow the container to use as much memory as it needs unless certain conditions are met, such as when the kernel detects low memory or contention on the host machine. Some of these options have different effects when used alone or when more than one option is set.
YESDocker network mode to use e.g. host, none, etc.
YESYESALWAYSIF_NOT_PRESENTALWAYSNEVERThe image pull policy for a container image and the tag of the image, which affect when Docker attempts to pull (download) the specified image.
YESSize of /dev/shm in bytes.
The size must be greater than 0. If omitted, the system uses 64MB.
YESUser in the Docker container.
YESList of volumes to mount.
Must be a valid mount expression as string, example : /home/user:/app.
Volumes mount are disabled by default for security reasons; you must enable them on server configuration by setting kestra.tasks.scripts.docker.volume-enabled to true.
YESThe registry authentication.
The auth field is a base64-encoded authentication string of username: password or a token.
YESThe identity token.
YESThe registry password.
YESThe registry URL.
If not defined, the registry will be extracted from the image name.
YESThe registry token.
YESThe registry username.
YESA list of capabilities; an OR list of AND lists of capabilities.
YESYESYESYESDriver-specific options, specified as key/value pairs.
These options are passed directly to the driver.
