container Deploy

Description

Deploy a container image, e.g. in a Kubernetes namespace (when used with the kubernetes provider).

This is a simplified abstraction, which can be convenient for simple deployments, but has limited features compared to more platform-specific types. For example, you cannot specify replicas for redundancy, and various platform-specific options are not included. For more flexibility, please look at other Deploy types like helm or kubernetes.

Below is the full schema reference for the action. For an introduction to configuring Garden, please look at our Configuration guide.

container 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.

TypeRequired

string

Yes

name

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

TypeRequired

string

Yes

description

A description of the action.

TypeRequired

string

No

source

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

You can override this by setting either source.path to another (POSIX-style) path relative to the action source directory, or source.repository to get the source from an external repository.

If using source.path, you must make sure the target path is in a git repository.

For source.repository behavior, please refer to the Remote Sources guide.

TypeRequired

object

No

source.path

source > path

A relative POSIX-style path to the source directory for this action. You must make sure this path exists and is in a git repository!

TypeRequired

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).

TypeRequired

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>

TypeRequired

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.

TypeDefaultRequired

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.

TypeDefaultRequired

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"}.

TypeRequired

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.

TypeRequired

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.

TypeRequired

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.

TypeRequired

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:

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

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

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

NOTE: The default varfile format will change 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, it is ignored.

TypeDefaultRequired

array[posixPath]

[]

No

Example:

varfiles:
  "my-action.env"

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.

Example:

spec:
  ...
  annotations:
      nginx.ingress.kubernetes.io/proxy-body-size: '0'

spec.sync.paths[].source

spec > sync > paths > source

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.

TypeDefaultRequired

string

spec:
  ...
  sync:
    ...
    paths:

spec.localMode

spec > localMode

[EXPERIMENTAL] Configures the local application which will send and receive network requests instead of the target resource.

The target service will be replaced by a proxy container which runs an SSH server to proxy requests. Reverse port-forwarding will be automatically configured to route traffic to the local service and back.

Local mode is enabled by setting the --local option on the garden deploy command. Local mode always takes the precedence over sync mode if there are any conflicting service names.

Health checks are disabled for services running in local mode.

See the Local Mode guide for more information.

Note! This feature is still experimental. Some incompatible changes can be made until the first non-experimental release.

spec.ports[].containerPort

spec > ports > containerPort

The port exposed on the container by the running process. This will also be the default value for servicePort. This is the port you would expose in your Dockerfile and that your process listens on. This is commonly a non-privileged port like 8080 for security reasons. The service port maps to the container port: servicePort:80 -> containerPort:8080 -> process:8080

TypeRequired

spec.ports[].servicePort

spec > ports > servicePort

The port exposed on the service. Defaults to containerPort if not specified. This is the port you use when calling a service from another service within the cluster. For example, if your service name is my-service and the service port is 8090, you would call it with: http://my-service:8090/some-endpoint. It is common to use port 80, the default port number, so that you can call the service directly with http://my-service/some-endpoint. The service port maps to the container port: servicePort:80 -> containerPort:8080 -> process:8080

TypeRequired

number

No

Example:

TypeRequired

number

No

spec.ports[].nodePort

spec > ports > nodePort

Set this to expose the service on the specified port on the host node (may not be supported by all providers). Set to true to have the cluster pick a port automatically, which is most often advisable if the cluster is shared by multiple users. This allows you to call the service from the outside by the node's IP address and the port number set in this field.

TypeRequired

number

No

spec.replicas

spec > replicas

The number of instances of the service to deploy. Defaults to 3 for environments configured with production: true, otherwise 1. Note: This setting may be overridden or ignored in some cases. For example, when running with daemon: true or if the provider doesn't support multiple replicas.

No

Outputs

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

TypeDefault

string

"default"

Example:

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

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

The variables configured on the action.
