The following environment variables are available for use in the delegate manifest. Some of these variables are included in the YAML by default; you can specify others based on use case.
The Harness account Id of the account with which this delegate registers.
This value is automatically added to the delegate configuration file (the application manifest of a Kubernetes delegate) when you add the delegate.
- name: ACCOUNT_ID
The Harness account token that is used to register the delegate.
- name: ACCOUNT_SECRET
The CDN URL for delegate versions.
- name: CDN_URL
The storage location that hosts published versions of the delegate.

- name: DELEGATE_DESCRIPTION
The name of the delegate. This is the name that identifies a registered delegate in Harness.
This value is not specified when delegate creation is automated. Instead, a script is used to duplicate the delegate YAML file and add a unique name to the
DELEGATE_NAME environment variable for each delegate to be registered. See Automate Delegate Installation.
- name: DELEGATE_NAME
The namespace for the delegate is taken from the
- name: DELEGATE_NAMESPACE
The Harness organization Identifier in which the delegate registers.
Delegates at the account level do not have a value for this variable.

Delegates at the account or organization level do not have a value for this variable.
- name: DELEGATE_PROJECT_IDENTIFIER
The URL location at which published delegate JAR files are stored.
- name: DELEGATE_STORAGE_URL

- name: DELEGATE_TAGS
- name: DELEGATE_TAGS
value: has_jq, has_gcloud
The maximum number of tasks the delegate can concurrently perform.

HELM\_DESIRED\_VERSION environment property. Include the "v" with the version. For example,

apt-get install wget
echo wget installed
