kubernetes Deploy

Description

Specify one or more Kubernetes manifests to deploy.

You can either (or both) specify the manifests as part of the garden.yml configuration, or you can refer to one or more files with existing manifests.

Note that if you include the manifests in the garden.yml file, you can use template strings to interpolate values into the manifests.

If you need more advanced templating features you can use the helm Deploy type.

Below is the full schema reference for the action.

kubernetes actions also export values that are available in template strings. See the Outputs section below for details.

Configuration Keys

type

The type of action, e.g. exec, container or kubernetes. Some are built into Garden but mostly these will be defined by your configured providers.

Type	Required
string	Yes

name

A valid name for the action. Must be unique across all actions of the same kind in your project.

Type	Required
string	Yes

description

A description of the action.

Type	Required
string	No

source

By default, the directory where the action is defined is used as the source for the build context.

You can override the directory that is used for the build context by setting source.path.

You can use source.repository to get the source from an external repository. For more information on remote actions, please refer to the Remote Sources guide.

Type	Required
object	No

source.path

source > path

A relative POSIX-style path to the source directory for this action.

If specified together with source.repository, the path will be relative to the repository root.

Otherwise, the path will be relative to the directory containing the Garden configuration file.

Type	Required
posixPath	No

source.repository

source > repository

When set, Garden will import the action source from this repository, but use this action configuration (and not scan for configs in the separate repository).

Type	Required
object	No

source.repository.url

source > repository > url

A remote repository URL. Currently only supports git servers. Must contain a hash suffix pointing to a specific branch or tag, with the format: #<branch|tag>

Type	Required
gitUrl | string	Yes

Example:

source:
  ...
  repository:
    ...
    url: "git+https://github.com/org/repo.git#v2.0"

dependencies[]

A list of other actions that this action depends on, and should be built, deployed or run (depending on the action type) before processing this action.

Each dependency should generally be expressed as a "<kind>.<name>" string, where is one of build, deploy, run or test, and is the name of the action to depend on.

You may also optionally specify a dependency as an object, e.g. { kind: "Build", name: "some-image" }.

Any empty values (i.e. null or empty strings) are ignored, so that you can conditionally add in a dependency via template expressions.

Type	Default	Required
array[actionReference]	[]	No

Example:

dependencies:
  - build.my-image
  - deploy.api

disabled

Set this to true to disable the action. You can use this with conditional template strings to disable actions based on, for example, the current environment or other variables (e.g. disabled: ${environment.name == "prod"}). This can be handy when you only need certain actions for specific environments, e.g. only for development.

For Build actions, this means the build is not performed unless it is declared as a dependency by another enabled action (in which case the Build is assumed to be necessary for the dependant action to be run or built).

For other action kinds, the action is skipped in all scenarios, and dependency declarations to it are ignored. Note however that template strings referencing outputs (i.e. runtime outputs) will fail to resolve when the action is disabled, so you need to make sure to provide alternate values for those if you're using them, using conditional expressions.

Type	Default	Required
boolean	false	No

environments[]

If set, the action is only enabled for the listed environment types. This is effectively a cleaner shorthand for the disabled field with an expression for environments. For example, environments: ["prod"] is equivalent to disabled: ${environment.name != "prod"}.

Type	Required
array[string]	No

include[]

Specify a list of POSIX-style paths or globs that should be regarded as source files for this action, and thus will affect the computed version of the action.

For actions other than Build actions, this is usually not necessary to specify, or is implicitly inferred. An exception would be e.g. an exec action without a build reference, where the relevant files cannot be inferred and you want to define which files should affect the version of the action, e.g. to make sure a Test action is run when certain files are modified.

Build actions have a different behavior, since they generally are based on some files in the source tree, so please reference the docs for more information on those.

Note that you can also exclude files using the exclude field or by placing .gardenignore files in your source tree, which use the same format as .gitignore files. See the Configuration Files guide for details.

Type	Required
array[posixPath]	No

Example:

include:
  - my-app.js
  - some-assets/**/*

exclude[]

Specify a list of POSIX-style paths or glob patterns that should be explicitly excluded from the action's version.

For actions other than Build actions, this is usually not necessary to specify, or is implicitly inferred. For Deploy, Run and Test actions, the exclusions specified here only applied on top of explicitly set include paths, or such paths inferred by providers. See the Configuration Files guide for details.

Unlike the scan.exclude field in the project config, the filters here have no effect on which files and directories are watched for changes when watching is enabled. Use the project scan.exclude field to affect those, if you have large directories that should not be watched for changes.

Type	Required
array[posixPath]	No

Example:

exclude:
  - tmp/**/*
  - '*.log'

variables

A map of variables scoped to this particular action. These are resolved before any other parts of the action configuration and take precedence over group-scoped variables (if applicable) and project-scoped variables, in that order. They may reference group-scoped and project-scoped variables, and generally can use any template strings normally allowed when resolving the action.

Type	Required
object	No

varfiles[]

Specify a list of paths (relative to the directory where the action is defined) to a file containing variables, that we apply on top of the action-level variables field, and take precedence over group-level variables (if applicable) and project-level variables, in that order.

If you specify multiple paths, they are merged in the order specified, i.e. the last one takes precedence over the previous ones.

The format of the files is determined by the configured file's extension:

• .yaml/.yml - YAML. The file must consist of a YAML document, which must be a map (dictionary). Keys may contain any value type. YAML format is used by default.

• .env - Standard "dotenv" format, as defined by dotenv.

• .json - JSON. Must contain a single JSON object (not an array).

NOTE: The default varfile format was changed to YAML in Garden v0.13, since YAML allows for definition of nested objects and arrays.

To use different varfiles in different environments, you can template in the environment name to the varfile name, e.g. varfile: "my-action.${environment.name}.env" (this assumes that the corresponding varfiles exist).

If a listed varfile cannot be found, throwing an error. To add optional varfiles, you can use a list item object with a path and an optional optional boolean field.

varfiles:
  - path: my-action.env
    optional: true

Type	Default	Required
array[alternatives]	[]	No

Example:

varfiles:
  "my-action.env"

varfiles[].path

varfiles > path

Path to a file containing a path.

Type	Required
posixPath	Yes

varfiles[].optional

varfiles > optional

Whether the varfile is optional.

Type	Required
boolean	No

build

Specify a Build action, and resolve this action from the context of that Build.

For example, you might create an exec Build which prepares some manifests, and then reference that in a kubernetes Deploy action, and the resulting manifests from the Build.

This would mean that instead of looking for manifest files relative to this action's location in your project structure, the output directory for the referenced exec Build would be the source.

Type	Required
string	No

kind

Type	Allowed Values	Required
string	"Deploy"	Yes

timeout

Timeout for the deploy to complete, in seconds.

Type	Default	Required
number	300	No

spec

Type	Required
object	No

spec.kustomize

spec > kustomize

Resolve the specified kustomization and include the resulting resources. Note that if you specify files or manifests as well, these are also included.

Type	Required
object	No

spec.kustomize.path

spec > kustomize > path

The directory path where the desired kustomization.yaml is, or a git repository URL. This could be the path to an overlay directory, for example. If it's a path, must be a relative POSIX-style path and must be within the action root. Defaults to the action root. If you set this to null, kustomize will not be run.

Type	Default	Required
posixPath | string	"."	No

spec.kustomize.version

spec > kustomize > version

The Kustomize version to use.

Type	Allowed Values	Default	Required
number	4, 5	5	Yes

spec.kustomize.extraArgs[]

spec > kustomize > extraArgs

Type	Required
string	Yes

spec.patchResources[]

spec > patchResources

A list of resources to patch using Kubernetes' patch strategies. This is useful for e.g. overwriting a given container image name with an image built by Garden without having to actually modify the underlying Kubernetes manifest in your source code. Another common example is to use this to change the number of replicas for a given Kubernetes Deployment.

Under the hood, Garden just applies the kubectl patch command to the resource that matches the specified kind and name.

Patches are applied to file manifests, inline manifests, and kustomize files.

You can learn more about patching Kubernetes resources here: https://kubernetes.io/docs/tasks/manage-kubernetes-objects/update-api-object-kubectl-patch/

Type	Required
string	No

spec.portForwards[]

spec > portForwards

Manually specify port forwards that Garden should set up when deploying in dev or watch mode. If specified, these override the auto-detection of forwardable ports, so you'll need to specify the full list of port forwards to create.

array[object]	No

spec.portForwards[].name

spec > portForwards > name

An identifier to describe the port forward.

Type	Required
string	No

spec.portForwards[].resource

spec > portForwards > resource

The full resource kind and name to forward to, e.g. Service/my-service or Deployment/my-deployment. Note that Garden will not validate this ahead of attempting to start the port forward, so you need to make sure this is correctly set. The types of resources supported will match that of the kubectl port-forward CLI command.

spec.defaultTarget

spec > defaultTarget

Specify a default resource in the deployment to use for syncs, local mode, and for the garden exec command.

Specify either kind and name, or a podSelector. The resource should be one of the resources deployed by this action (otherwise the target is not guaranteed to be deployed with adjustments required for syncing or local mode).

Set containerName to specify a container to connect to in the remote Pod. By default the first container in the Pod is used.

Note that if you specify podSelector here, it is not validated to be a selector matching one of the resources deployed by the action.

If you have multiple syncs for the Deploy, you can use the defaults field to set common configuration for every individual sync.

Type	Required
object	No

Path to a local directory to be synchronized with the target. This should generally be a templated path to another action's source path (e.g. ${actions.build.my-container-image.sourcePath}), or a relative path. If a path is hard-coded, we recommend sticking with relative paths here, and using forward slashes (/) as a delimiter, as Windows-style paths with back slashes (\) and absolute paths will work on some platforms, but they are not portable and will not work for users on other platforms. Defaults to the Deploy action's config's directory if no value is provided.

Outputs

The following keys are available via the ${actions.deploy.<name>} template string key for kubernetes action.

${actions.deploy.<name>.name}

The name of the action.

Type
string

${actions.deploy.<name>.disabled}

Whether the action is disabled.

Type
boolean

Example:

my-variable: ${actions.deploy.my-deploy.disabled}

${actions.deploy.<name>.buildPath}

The local path to the action build directory.

Type
string

Example:

my-variable: ${actions.deploy.my-deploy.buildPath}

${actions.deploy.<name>.sourcePath}

The local path to the action source directory.

Type
string

Example:

my-variable: ${actions.deploy.my-deploy.sourcePath}

${actions.deploy.<name>.mode}

The mode that the action should be executed in (e.g. 'sync' or 'local' for Deploy actions). Set to 'default' if no special mode is being used.

Build actions inherit the mode from Deploy actions that depend on them. E.g. If a Deploy action is in 'sync' mode and depends on a Build action, the Build action will inherit the 'sync' mode setting from the Deploy action. This enables installing different tools that may be necessary for different development modes.

Type	Default
string	"default"

Example:

my-variable: ${actions.deploy.my-deploy.mode}

${actions.deploy.<name>.var.*}

The variables configured on the action.

Type	Default
object	{}

${actions.deploy.<name>.var.<name>}
