Inputs
Name | Description | Type | Default | Required |
---|---|---|---|---|
additional_tag_map | Additional key-value pairs to add to each map in tags_as_list_of_maps . Not added to tags or id .This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration. | map(string) | {} | no |
atomic | If set, installation process purges chart on fail. The wait flag will be set automatically if atomic is used. | bool | true | no |
attributes | ID element. Additional attributes (e.g. workers or cluster ) to add to id ,in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element. | list(string) | [] | no |
chart | Chart name to be installed. The chart name can be local path, a URL to a chart, or the name of the chart if repository is specified. It is also possible to use the <repository>/<chart> format here if you are running Terraform on a system that the repository has been added to with helm repo add but this is not recommended. | string | n/a | yes |
chart_description | Set release description attribute (visible in the history). | string | null | no |
chart_repository | Repository URL where to locate the requested chart. | string | n/a | yes |
chart_values | Additional values to yamlencode as helm_release values. | any | {} | no |
chart_version | Specify the exact chart version to install. If this is not specified, the latest version is installed. | string | null | no |
cleanup_on_fail | Allow deletion of new resources created in this upgrade when upgrade fails. | bool | true | no |
context | Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value.Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged. | any | { | no |
create_namespace | Create the namespace if it does not yet exist. Defaults to false . | bool | null | no |
delimiter | Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all. | string | null | no |
descriptor_formats | Describe additional descriptors to be output in the descriptors output map.Map of maps. Keys are names of descriptors. Values are maps of the form {<br/> format = string<br/> labels = list(string)<br/>} (Type is any so the map values can later be enhanced to provide additional options.)format is a Terraform format string to be passed to the format() function.labels is a list of labels, in order, to pass to format() function.Label values will be normalized before being passed to format() so they will beidentical to how they appear in id .Default is {} (descriptors output will be empty). | any | {} | no |
eks_component_name | The name of the eks component | string | "eks/cluster" | no |
enabled | Set to false to prevent the module from creating any resources | bool | null | no |
environment | ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT' | string | null | no |
helm_manifest_experiment_enabled | Enable storing of the rendered manifest for helm_release so the full diff of what is changing can been seen in the plan | bool | false | no |
id_length_limit | Limit id to this many characters (minimum 6).Set to 0 for unlimited length.Set to null for keep the existing setting, which defaults to 0 .Does not affect id_full . | number | null | no |
kube_data_auth_enabled | If true , use an aws_eks_cluster_auth data source to authenticate to the EKS cluster.Disabled by kubeconfig_file_enabled or kube_exec_auth_enabled . | bool | false | no |
kube_exec_auth_aws_profile | The AWS config profile for aws eks get-token to use | string | "" | no |
kube_exec_auth_aws_profile_enabled | If true , pass kube_exec_auth_aws_profile as the profile to aws eks get-token | bool | false | no |
kube_exec_auth_enabled | If true , use the Kubernetes provider exec feature to execute aws eks get-token to authenticate to the EKS cluster.Disabled by kubeconfig_file_enabled , overrides kube_data_auth_enabled . | bool | true | no |
kube_exec_auth_role_arn | The role ARN for aws eks get-token to use | string | "" | no |
kube_exec_auth_role_arn_enabled | If true , pass kube_exec_auth_role_arn as the role ARN to aws eks get-token | bool | true | no |
kubeconfig_context | Context to choose from the Kubernetes config file. If supplied, kubeconfig_context_format will be ignored. | string | "" | no |
kubeconfig_context_format | A format string to use for creating the kubectl context name whenkubeconfig_file_enabled is true and kubeconfig_context is not supplied.Must include a single %s which will be replaced with the cluster name. | string | "" | no |
kubeconfig_exec_auth_api_version | The Kubernetes API version of the credentials returned by the exec auth plugin | string | "client.authentication.k8s.io/v1beta1" | no |
kubeconfig_file | The Kubernetes provider config_path setting to use when kubeconfig_file_enabled is true | string | "" | no |
kubeconfig_file_enabled | If true , configure the Kubernetes provider with kubeconfig_file and use that kubeconfig file for authenticating to the EKS cluster | bool | false | no |
kubernetes_namespace | The namespace to install the release into. | string | n/a | yes |
label_key_case | Controls the letter case of the tags keys (label names) for tags generated by this module.Does not affect keys of tags passed in via the tags input.Possible values: lower , title , upper .Default value: title . | string | null | no |
label_order | The order in which the labels (ID elements) appear in the id .Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present. | list(string) | null | no |
label_value_case | Controls the letter case of ID elements (labels) as included in id ,set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input.Possible values: lower , title , upper and none (no transformation).Set this to title and set delimiter to "" to yield Pascal Case IDs.Default value: lower . | string | null | no |
labels_as_tags | Set of labels (ID elements) to include as tags in the tags output.Default is to include all labels. Tags with empty values will not be included in the tags output.Set to [] to suppress all generated tags.Notes: The value of the name tag, if included, will be the id , not the name .Unlike other null-label inputs, the initial setting of labels_as_tags cannot bechanged in later chained modules.
