Setup Setup

yaml
type: "io.kestra.plugin.dbt.cli.Setup"

Setup dbt in a Python virtualenv.

Use it to install dbt requirements locally in a Python virtualenv if you don't want to use dbt via Docker. In this case, you need to use a WorkingDirectory task and this Setup task to setup dbt prior to using any of the dbt tasks.

Examples

Setup dbt by installing pip dependencies in a Python virtualenv and initializing the profile directory.

Properties

exitOnFailed

  • Type: boolean
  • Dynamic: ❌
  • Required: ✔️
  • Default: true

Exit if any non true return value.

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. This option is deprecated. Use failFast instead.

interpreter

  • Type: array
  • SubType: string
  • Dynamic: ❌
  • Required: ✔️
  • Default: [/bin/sh, -c]
  • Min items: 1

Which interpreter to use.

  • Default: true

Fail the task on the first command with a non-zero status.

If set to false all commands will be executed one after the other. The final state of task execution is determined by the last command. Note that this property maybe be ignored if a non compatible interpreter is specified.

inputFiles

  • SubType: string
  • Dynamic: ✔️
  • Required: ❌

Input files are extra files that will be available in the dbt working directory.

You can define the files as map or a JSON string. Each file can be defined inlined or can reference a file from Kestra's internal storage.

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.

outputDirectory

Definitions

io.kestra.core.models.tasks.NamespaceFiles

Properties

enabled
  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: true

Whether to enable namespace files to be loaded into the working directory. If explicitly set to true in a task, it will load all Namespace Files into the task's working directory. Note that this property is by default set to true so that you can specify only the include and exclude properties to filter the files to load without having to explicitly set enabled to true.

exclude
  • Type: array
  • SubType: string
  • Dynamic: ❌
  • Required: ❌

A 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.

include
  • Type: array
  • SubType: string
  • Dynamic: ❌
  • Required: ❌

A 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.

io.kestra.plugin.scripts.runner.docker.Cpu

Properties

cpus
  • Type: integer
  • Dynamic: ❌
  • Required: ❌

The maximum amount of CPU resources a container can use.

For instance, if the host machine has two CPUs and you set cpus:"1.5", the container is guaranteed at most one and a half of the CPUs.

io.kestra.core.models.tasks.runners.TaskRunner

io.kestra.plugin.scripts.runner.docker.Memory

Properties

kernelMemory
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

The maximum amount of kernel memory the container can use.

The minimum allowed value is 4m. 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 --kernel-memory details.

memory
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

The maximum amount of memory resources the container can use.

It is recommended that you set the value to at least 6 megabytes.

memoryReservation
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

Allows 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.

memorySwap
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

The amount of memory this container is allowed to swap to disk.

If memory and memorySwap are set to the same value, this prevents containers from using any swap. This is because memorySwap is the amount of combined memory and swap that can be used, while memory is only the amount of physical memory that can be used.

memorySwappiness
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

The amount of memory this container is allowed to swap to disk.

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.

oomKillDisable
  • Type: boolean
  • Dynamic: ❌
  • Required: ❌

By default, if an out-of-memory (OOM) error occurs, the kernel kills processes in a container.

To change this behavior, use the oomKillDisable option. Only disable the OOM killer on containers where you have also set the memory option. If the memory flag is not set, the host can run out of memory, and the kernel may need to kill the host system’s processes to free the memory.

io.kestra.plugin.scripts.exec.scripts.models.DockerOptions

Properties

image
  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Min length: 1

    • string
    • object
  • Dynamic: ✔️
  • Required: ❌

Docker configuration file that can set access credentials to private container registries. Usually located in ~/.docker/config.json.

cpu
  • Type: Cpu
  • Dynamic: ❌
  • Required: ❌

Limits 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.

credentials
deviceRequests

A list of device requests to be sent to device drivers.

entryPoint

  • Dynamic: ✔️
  • Required: ❌

Docker API URI.

memory
  • Type: Memory
  • Dynamic: ❌
  • Required: ❌

Limits 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.

networkMode
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

Docker network mode to use e.g. host, none, etc.

pullPolicy
  • Type: string
  • Dynamic: ❌

  • Default: ALWAYS
  • Possible Values:
    • IF_NOT_PRESENT
    • ALWAYS
    • NEVER

The image pull policy for a container image and the tag of the image, which affect when Docker attempts to pull (download) the specified image.

shmSize
  • Type: string
  • Dynamic: ✔️
  • Required: ❌

The size must be greater than 0. If omitted, the system uses 64MB.

user

  • Dynamic: ✔️
  • Required: ❌

volumes
  • Type: array
  • SubType: string
  • Dynamic: ✔️
  • Required: ❌

List of volumes to mount.
