The image used for the file sidecar container.

The maximum amount of CPU resources a container can use.

Make sure to set that to a numeric value e.g. cpus: "1.5" or cpus: "4" or 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.

The registry authentication.

The auth field is a base64-encoded authentication string of username: password or a token.

The identity token.

The registry password.

The registry URL.

If not defined, the registry will be extracted from the image name.

The registry token.

The registry username.

The ARM resource ID of the user assigned identity.

Extra boot disk size for each task.

The milliCPU count.

Defines the amount of CPU resources per task in milliCPU units. For example, 1000 corresponds to 1 vCPU per task. If undefined, the default value is 2000. If you also define the VM's machine type using the machineType property in InstancePolicy field or inside the instanceTemplate in the InstancePolicyOrTemplate field, make sure the CPU resources for both fields are compatible with each other and with how many tasks you want to allow to run on the same VM at the same time.

For example, if you specify the n2-standard-2 machine type, which has 2 vCPUs, you can set the cpu to no more than 2000. Alternatively, you can run two tasks on the same VM if you set the cpu to 1000 or less.

Memory in MiB.

Defines the amount of memory per task in MiB units. If undefined, the default value is 2048. If you also define the VM's machine type using the machineType in InstancePolicy field or inside the instanceTemplate in the InstancePolicyOrTemplate field, make sure the memory resources for both fields are compatible with each other and with how many tasks you want to allow to run on the same VM at the same time.

For example, if you specify the n2-standard-2 machine type, which has 8 GiB of memory, you can set the memory to no more than 8192.

The namespace where the pod will be created.

Whether to reconnect to the current pod if it already exists.

The additional duration to wait for logs to arrive after pod completion.

As logs are not retrieved in real time, we cannot guarantee that we have fetched all logs when the pod complete, therefore we wait for a fixed amount of time to fetch late logs.

The maximum duration to wait until the pod is created.

This timeout is the maximum time that Kubernetes scheduler can take to

• schedule the pod
• pull the pod image
• and start the pod.

The configuration of the target Kubernetes cluster.

Id of the pool on which to run the job.

Whether to reconnect to the current job if it already exists.

Determines how often Kestra should poll the container for completion. By default, the task runner checks every 5 seconds whether the job is completed. You can set this to a lower value (e.g. PT0.1S = every 100 milliseconds) for quick jobs and to a lower threshold (e.g. PT1M = every minute) for long-running jobs. Setting this property to a lower value will reduce the number of API calls Kestra makes to the remote service — keep that in mind in case you see API rate limit errors.

Whether the job should be deleted upon completion.

Warning, if the job is not deleted, a retry of the task could resume an old failed attempt of the job.

Compute resource requirements.

ComputeResource defines the amount of resources required for each task. Make sure your tasks have enough compute resources to successfully run. If you also define the types of resources for a job to use with the InstancePolicyOrTemplate field, make sure both fields are compatible with each other.

Whether the job should be deleted upon completion.

Warning, if the job is not deleted, a retry of the task could resume an old failed attempt of the job.

Container entrypoint to use.

Lifecycle management schema when any task in a task group is failed.

Currently we only support one lifecycle policy. When the lifecycle policy condition is met, the action in the policy will execute. If task execution result does not meet with the defined lifecycle policy, we consider it as the default policy. Default policy means if the exit code is 0, exit task. If task ends with non-zero exit code, retry the task with max_retry_count.

Maximum number of retries on failures.

The default, 0, which means never retry.

Google Cloud Batch will automatically timeout the job upon reaching such duration and the task will be failed.

The 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.

The 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.

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.

The 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.

A 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.

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.

The reference to the user assigned identity to use to access the Azure Container Registry instead of username and password.

Docker configuration file.

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

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.

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

Docker entrypoint to use.

Extra hostname mappings to the container network interface configuration.

Docker API URI.

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.

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

Give extended privileges to this container.

File handling strategy.

How to handle local files (input files, output files, namespace files, ...). By default, we create a volume and copy the file into the volume bind path. Configuring it to MOUNT will mount the working directory instead.

Docker configuration file.

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

Limits the CPU usage to a given maximum threshold value.

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

Docker entrypoint to use.

Extra hostname mappings to the container network interface configuration.

Docker API URI.

When a task is killed, this property sets the grace period before killing the container.

By default, we kill the container immediately when a task is killed. Optionally, you can configure a grace period so the container is stopped with a grace period instead.

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.

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

List of port bindings.

Corresponds to the --publish (-p) option of the docker run CLI command using the format ip: dockerHostPort: containerPort/protocol. Possible example :

User in the Docker container.

The version of the plugin to use.

List of volumes to mount.

Make sure to provide a map of a local path to a container path in the format: /home/local/path:/app/container/path. Volume mounts are disabled by default for security reasons — if you are sure you want to use them, enable that feature in the plugin configuration by setting volume-enabled to true.

Here is how you can add that setting to your kestra configuration:

kestra: 
  plugins: 
    configurations: 
      - type: io.kestra.plugin.scripts.runner.docker.Docker
        values: 
          volume-enabled: true

Determines how often Kestra should poll the container for completion. By default, the task runner checks every 5 seconds whether the job is completed. You can set this to a lower value (e.g. PT0.1S = every 100 milliseconds) for quick jobs and to a lower threshold (e.g. PT1M = every minute) for long-running jobs. Setting this property to a lower value will reduce the number of API calls Kestra makes to the remote service — keep that in mind in case you see API rate limit errors.
