`exitOnFailed`

Type: boolean

Definitions

`DockerOptions-Memory`

`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 the container can use.

That is, you must 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 memory.

`DockerOptions`

`image`

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

Docker image to use

`cpu`

Type: DockerOptions-Cpu
Dynamic: ❌
Required: ❌

Limits cpu usage.

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.

`deviceRequests`

Type: array
SubType: DockerOptions-DeviceRequest
Dynamic: ❌
Required: ❌

A list of request for devices to be sent to device drivers

`dockerConfig`

Type: string
Dynamic: ✔️
Required: ❌

Docker config file

Full file that can be used to configure private registries, ...

`dockerHost`

Type: string
Dynamic: ✔️
Required: ❌

Docker api uri

`entryPoint`

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

Docker entrypoint to use

`extraHosts`

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

Docker extra host to use

`memory`

Type: DockerOptions-Memory
Dynamic: ❌
Required: ❌

Limits memory usage.

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

`pullImage`

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

Is a pull of image must be done before starting the container

Mostly used for local image with registry

`user`

Type: string
Dynamic: ✔️
Required: ❌

`volumes`

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

List 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 enabled on server configuration with kestra.tasks.scripts.docker.volume-enabled to true
