Parameter reference

Global

Param name	Type	Alias	Purpose
mode	string	helm_command	Indicates the operation to perform. Recommended, but not required. Valid options are upgrade, uninstall, lint, and help.
update_dependencies	boolean		Calls helm dependency update before running the main command.
add_repos	list<string>	helm_repos	Calls helm repo add $repo before running the main command. Each string should be formatted as repo_name=https://repo.url/.
namespace	string		Kubernetes namespace to use for this operation.
debug	boolean		Generate debug output within drone-helm3 and pass --debug to all helm commands. Use with care, since the debug output may include secrets.

Linting

Linting is only triggered when the mode setting is "lint".

Param name	Type	Required	Purpose
chart	string	yes	The chart to be linted. Must be a local path.
values	list<string>		Chart values to use as the --set argument to helm lint.
string_values	list<string>		Chart values to use as the --set-string argument to helm lint.
values_files	list<string>		Values to use as --values arguments to helm lint.
lint_strictly	boolean		Pass --strict to helm lint, to turn warnings into errors.

Installation

Installations are triggered when the mode setting is "upgrade." They can also be triggered when the build was triggered by a push, tag, deployment, pull_request, promote, or rollback Drone event.

Param name	Type	Required	Alias	Purpose
chart	string	yes		The chart to use for this installation.
release	string	yes		The release name for helm to use.
kube_api_server	string	yes	api_server	API endpoint for the Kubernetes cluster.
kube_token	string	yes	kubernetes_token	Token for authenticating to Kubernetes.
kube_service_account	string		service_account	Service account for authenticating to Kubernetes. Default is helm.
kube_certificate	string		kubernetes_certificate	Base64 encoded TLS certificate used by the Kubernetes cluster's certificate authority.
chart_version	string			Specific chart version to install.
dry_run	boolean			Pass --dry-run to helm upgrade.
wait_for_upgrade	boolean		wait	Wait until kubernetes resources are in a ready state before marking the installation successful.
timeout	duration			Timeout for any individual Kubernetes operation. The installation's full runtime may exceed this duration.
force_upgrade	boolean		force	Pass --force to helm upgrade.
atomic_upgrade	boolean			Pass --atomic to helm upgrade.
cleanup_failed_upgrade	boolean			Pass --cleanup-on-fail to helm upgrade.
values	list<string>			Chart values to use as the --set argument to helm upgrade.
string_values	list<string>			Chart values to use as the --set-string argument to helm upgrade.
values_files	list<string>			Values to use as --values arguments to helm upgrade.
reuse_values	boolean			Reuse the values from a previous release.
skip_tls_verify	boolean			Connect to the Kubernetes cluster without checking for a valid TLS certificate. Not recommended in production.

Uninstallation

Uninstallations are triggered when the mode setting is "uninstall" or "delete." They can also be triggered when the build was triggered by a delete Drone event.

Param name	Type	Required	Alias	Purpose
release	string	yes		The release name for helm to use.
kube_api_server	string	yes	api_server	API endpoint for the Kubernetes cluster.
kube_token	string	yes	kubernetes_token	Token for authenticating to Kubernetes.
kube_service_account	string		service_account	Service account for authenticating to Kubernetes. Default is helm.
kube_certificate	string		kubernetes_certificate	Base64 encoded TLS certificate used by the Kubernetes cluster's certificate authority.
keep_history	boolean			Pass --keep-history to helm uninstall, to retain the release history.
dry_run	boolean			Pass --dry-run to helm uninstall.
timeout	duration			Timeout for any individual Kubernetes operation. The uninstallation's full runtime may exceed this duration.
skip_tls_verify	boolean			Connect to the Kubernetes cluster without checking for a valid TLS certificate. Not recommended in production.
chart	string			Required when the global update_dependencies parameter is true. No effect otherwise.

Where to put settings

Any setting can go in either the settings or environment section. If a setting exists in both sections, the version in environment will override the version in settings.

We recommend putting all drone-helm3 configuration in the settings block and limiting the environment block to variables that are used when building your charts.

Formatting non-string values

• Booleans can be yaml's true and false literals or the strings "true" and "false".
• Durations are strings formatted with the syntax accepted by golang's ParseDuration function (e.g. 5m30s)
  • For backward-compatibility with drone-helm, a duration can also be an integer, in which case it will be interpreted to mean seconds.
• List<string>s can be a yaml sequence or a comma-separated string.

All of the following are equivalent:

values: "foo=1,bar=2"
values: ["foo=1", "bar=2"]
values:
  - foo=1
  - bar=2

Note that list members must not contain commas. Both of the following are equivalent:

values_files: [ "./over_9,000.yml" ]
values_files: [ "./over_9", "000.yml" ]

Backward-compatibility aliases

Some settings have alternate names, for backward-compatibility with drone-helm. We recommend using the canonical name unless you require the backward-compatible form.

Canonical name	Alias
mode	helm_command
add_repos	helm_repos
kube_api_server	api_server
kube_service_account	service_account
kube_token	kubernetes_token
kube_certificate	kubernetes_certificate
wait_for_upgrade	wait
force_upgrade	force
