Workflow Configuration

Below is the schema reference for Workflow configuration files. For an introduction to configuring a Garden project, please look at our configuration guide.

The reference is divided into two sections:

YAML Schema contains the config YAML schema
Configuration keys describes each individual schema key for the configuration files.

YAML Schema

The values in the schema below are the default values.

# The schema version of this workflow's config (currently not used).
apiVersion: garden.io/v0

# A list of files to write before starting the workflow.
#
# This is useful to e.g. create files required for provider authentication, and can be created from data stored in
# secrets or templated strings.
#
# Note that you cannot reference provider configuration in template strings within this field, since they are resolved
# after these files are generated. This means you can reference the files specified here in your provider
# configurations.
files:
  - # POSIX-style path to write the file to, relative to the project root (or absolute). If the path contains one
    # or more directories, they are created automatically if necessary.
    # If any of those directories conflict with existing file paths, or if the file path conflicts with an existing
    # directory path, an error will be thrown.
    # **Any existing file with the same path will be overwritten, so be careful not to accidentally overwrite files
    # unrelated to your workflow.**

    # The file data as a string.

    # with following enabled etc.—are not supported. In general, workflow steps should run to completion.
