Features

Overview

Features are building blocks for constructing Workload Profiles . They bundle predefined properties and specific UI / API behavior.

Use can use features to help build Custom Workload Profiles quickly. The Platform Orchestrator’s built-in Workload Profiles are also composed out of features.

The following features are available. Keep in mind that some features have dependencies on others to work, as stated in the Requires column.

Runtime only features don’t influence the editing interface of a Workload, but are used to enable specific capabilities when viewing a running Workload.

Top-level features

Feature Description Requires
humanitec/annotations Defined annotations on your Workload
humanitec/containers Contains a list of container. The available container sub-features are described below.
humanitec/ingress [DEPRECATED - use a route instead] Configure an ingress resource humanitec/service to add the necessary ports
humanitec/labels Defined labels on your Workload
humanitec/schedules Define schedules e.g. in a cronjob Workload
humanitec/service-account Specify a service account
humanitec/service Define service ports and container ports
humanitec/volumes Define additional volumes. (Usually hidden)
humanitec/image-pull-secrets Define image pull secrets. (Required if you Humanitec manages your registry credentials or use the built in registry)
humanitec/extra-containers Additional containers that might be injected by the Platform Orchestrator. (Usually hidden)
humanitec/extra-variables Additional variables that might be injected by the Platform Orchestrator. (Usually hidden)
humanitec/extra-volumes Additional volumes that might be injected by the Platform Orchestrator. (Usually hidden)
humanitec/replicas (Runtime only) Enable the modification of the replica count in the UI.

Sub-features

Sub-features are usually used inside a humanitec/container collection.

Feature Description Requires
humanitec/image Select a container image.
humanitec/variables Provides variables that can be used in a container, with support for resolving Humanitec placeholders to resources and values. humanitec/env (inside humanitec/container) to mount the resulting environment variables. humanitec/annotations to re-deploy your Workload in case of changes.
humanitec/files Mount files as volumes humanitec/volume-mounts (inside humanitec/container) to mount the resulting volumes.humanitec/extra-variables to hold the file content.
humanitec/volume-mounts Define volume mount inside the container
humanitec/probe Configure a probe (can be used inside liveness or readiness probes)
humanitec/resources Defined container resources
humanitec/overrides Use for CMD or ARG overrides
humanitec/envs Define environment variables. (Usually hidden)
humanitec/logs (Runtime only) Surface container logs inside the UI.

JSON schema

The complete JSON input schema for each feature can be fetched from the Humanitec API.

Set the following environment variables:

Variable Example Description
HUMANITEC_TOKEN lsakdjhcals A Humanitec token of a user with the Member or above role on the Organization.
HUMANITEC_ORG my-org The Humanitec organization the Application is in. 

humctl api get /orgs/${HUMANITEC_ORG}/workload-profile-features \
  | jq .


curl -H "Authorization: Bearer $HUMANITEC_TOKEN" \
  https://api.humanitec.io/orgs/${HUMANITEC_ORG}/workload-profile-features \
  | jq .

humanitec/annotations

The annotations feature defines Annotations that are added to Pods generated for the Workload. Depending on how this feature is implemented by the Workload Profile itself, this may only make up a subset of annotations on the Pod.

Annotations are defined as a map with keys and values.

Keys are made up of an optional prefix followed by a name, separated by a slash (/).

  • The name segment is required and must be 63 characters or less, beginning and ending with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.
  • The prefix is optional. If specified, the prefix must be a DNS subdomain: a series of DNS labels separated by dots (.), not longer than 253 characters in total, followed by a slash (/).

Values do not have any validation requirements.

humanitec/containers - resources

Specify the minimum and maximum resources required for this container. Pods will not be scheduled unless the minimum requested resources are available for all containers in a Pod on a node. The Pod will either be throttled or terminated if the maximum resource limit is reached.

The minimum resource is specified by the requests property. The maximum resource is specified by the limits property.

Each of these properties supports the following:

Property Type Description
cpu String A decimal number representing the fractional number of CPUs. e.g. 0.25.
memory String The amount of memory as an integer number of bytes. The numbers can be scaled by appending E, P, T, G, M, k or their power-of-two equivalents: Ei, Pi, Ti, Gi, Mi, Ki to the end of the number.

humanitec/containers - volume-mounts

The top level of the volume_mounts object is a map with mount points paths as keys and volume mount objects as values. The mount points must be rooted paths and include at least one directory. They cannot be nested inside any other defined mount points or be a parent of any file specified in the Files section.

Both volumes provisioned via Humanitec Resources or as built-in types are supported.

Persistent Volumes are managed through the Resources system and must be referenced via their Resource ID, e.g. shared.nfs-share. Other volume types must be referenced via the definition in the volumes section, e.g. volumes.common-dir.

Property Type Description
id String The resource ID or volume ID to mount.
read_only Boolean Defines whether the volume should be mounted as read-only.
sub_path String Specifies a sub-directory in the volume to mount. Must be a relative path .

Note that in the Workload Profile Definition, the feature extra-variables must also be configured as it is a required dependency.

humanitec/labels

The labels feature defines Labels that will be added to Pods generated for the Workload. Depending on how this feature is implemented by the Workload Profile itself, this may only make up a subset of labels on the Pod.

Description

Labels are defined as a map with keys and values.

Keys are made up of an optional prefix followed by a name, separated by a slash (/).

  • The name segment is required and must be 63 characters or less, beginning and ending with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.
  • The prefix is optional. If specified, the prefix must be a DNS subdomain: a series of DNS labels separated by dots (.), not longer than 253 characters in total, followed by a slash (/).

Valid label value:

  • Must be 63 characters or less (can be empty).
  • Unless empty, must begin and end with an alphanumeric character ([a-z0-9A-Z]).
  • May contain dashes (-), underscores (_), dots (.), and alphanumerics in between.

humanitec/replicas (runtime only)

The replicas feature is a runtime only feature. It can be used to adjust the number of replicas on Workload Profiles that are implemented using Deployments or ReplicaSets via the Humanitec Portal.

Setting the target to 0 replicas and then back up again is a way to restart the Pod(s) of your Workload.

To restart all Deployments in an Application Environment, see pause Environments .

humanitec/schedules

The schedules feature defines one or more schedules under which the Workload should run as a Kubernetes CronJob .

Description

Kubernetes CronJobs must have exactly one cron expression defined for them. This feature provides the convenience of creating sets of CronJobs with the same basic configuration, but running on different schedules. As an extra level of flexibility, the command and arguments for the container can optionally be overridden.

The top level is a Map of schedule objects. The key must be a valid Humanitec ID. If empty, it will produce an error.

The schedule object has the following properties:

Property Type Description
schedule String A valid cron expression .
containers Object A Map with keys of container IDs in the Workload. The values are objects containing command and arg overrides.

This example shows schedules for a CronJob with one container with the id main-container. The schedule is every six hours.

The Score extension file specifies the humanitec/default-cronjob Workload Profile to use which supports the feature.

humanitec/service

The service feature defines how a service for the Workload is configured.

Description

The top level of the service feature only contains the property ports.

The ports property is a Map or port objects. The Key must be a valid Humanitec ID.

The port object has the following properties:

Property Type Description
service_port Integer The port exposed by the service. Must be in range 1 - 65535
container_port Integer The port a container in the Pod is listening on. Traffic will be mapped from service_port to container_port. If not specified, no mapping will occur. Must be in range 1 - 65535.
protocol String Must be one of TCP, UDP or SCTP.

This example shows a service configured with two ports. One exposes port 8080 and maps to port 3001 on the container. The other listens on 90245 expecting a UDP connection.
