Workflow File Reference

This page provides a complete reference for the env0.workflow.yaml (or .yml) file used to define env zero Workflows.

File Structure

The workflow file has two main sections:

environments (required) - Defines the sub-environments in the workflow
settings (optional) - Global workflow settings

Example:

env0.workflow.yaml

settings:
  environmentRemovalStrategy: detach # or destroy

environments:
  my-environment:
    name: "My Environment"
    templateName: "my-template"
    # ... additional configuration

Settings

Global settings that apply to the entire workflow. environmentRemovalStrategy (string) controls what happens when a sub-environment is removed from the workflow file.

Default: detach
detach - The environment is detached but not destroyed.
destroy - The environment is destroyed after you deploy the updated workflow.

Sub-Environment Properties

Each sub-environment is defined as a key-value pair under environments. The key is a unique alias for the sub-environment.

Core Properties

Property	Type	Required	Description
`name`	`string`	Yes	Display name shown in the env zero UI.
`templateName`	`string`	No*	Name of an existing env zero template. Cannot be used with `vcs`.
`vcs`	`object`	No*	Inline VCS configuration. Cannot be used with `templateName`.

* Either templateName or vcs must be specified, but not both.

Optional Properties

Property	Type	Default	Description
`needs`	`array`	`[]`	List of sub-environment aliases that must deploy before this one.
`revision`	`string`	-	Git revision (branch, tag, or commit SHA) to use.
`workspace`	`string`	-	For Terraform/OpenTofu, sets the workspace name. For Helm, sets the release name. For Pulumi/CloudFormation, sets the stack name.
`requiresApproval`	`boolean`	`false`	If `true`, deployment requires manual approval before proceeding.
`disabled`	`boolean` or `string`	`false`	If `true` or `"true"`, this sub-environment is skipped during deployment. Supports variable interpolation.

VCS Configuration

If you want to use your code directly without creating a template for it first, you can use the vcs object with the following properties:

Property	Type	Required	Default	Description
`type`	`string`	Yes	-	IaC type. Options: `terraform`, `opentofu`, `terragrunt`, `pulumi`, `k8s`, `cloudformation`, `helm`, `ansible`.
`repository`	`string`	Yes	-	Git repository URL (HTTPS or SSH).
`path`	`string`	No	`""`	Path within the repository where IaC code is located.
`revision`	`string`	No	-	Git revision (branch, tag, or commit) to use.

VCS Authentication Properties

Property	Type	Description
`tokenId`	`string`	ID of a stored VCS token for authentication.
`tokenName`	`string`	Display name of the VCS token.
`sshKeys`	`array`	SSH keys for repository authentication. Each item requires `id` and `name`.
`githubInstallationId`	`number`	GitHub App installation ID.
`bitbucketClientKey`	`string`	Bitbucket client key for Bitbucket Cloud.
`vcsConnectionId`	`string`	VCS connection ID for unified VCS integration.

VCS Provider Flags

Property	Type	Default	Description
`isGitLab`	`boolean`	`false`	Set to `true` for GitLab.com repositories.

`isAzureDevOps`	`boolean`	`false`	Set to `true` for Azure DevOps.

IaC Version Properties

Property	Type	Description
`terraformVersion`	`string`	Terraform version. Use a specific version (e.g., `1.5.7`) or `RESOLVE_FROM_TERRAFORM_CODE`.
`opentofuVersion`	`string`	OpenTofu version. Use a specific version (e.g., `1.6.0`).
`terragruntVersion`	`string`	Terragrunt version (e.g., `0.54.0`).
`terragruntTfBinary`	`string`	Underlying binary for Terragrunt: `terraform` (default) or `opentofu`.
`pulumiVersion`	`string`	Pulumi version (e.g., `3.100.0`).
`ansibleVersion`	`string`	Ansible version (e.g., `2.15.0`).

CloudFormation Properties

Property	Type	Default	Description

`isHelmRepository`	`boolean`	`false`	Set to `true` if the repository is a Helm chart repository.

Examples

Simple Workflow with Template References

A basic workflow using pre-defined templates with dependencies.

env0.workflow.yaml

environments:
  database:
    name: "PostgreSQL Database"
    templateName: "aws-rds-postgres"
    workspace: "production"

  api:
    name: "API Service"
    templateName: "kubernetes-deployment"
    needs:
      - database
    requiresApproval: true

Workflow with Inline VCS Configuration

Define IaC source directly without creating separate templates:

env0.workflow.yaml

environments:
  networking:
    name: "VPC and Networking"
    vcs:
      type: terraform
      repository: "https://github.com/myorg/infrastructure"
      path: "terraform/networking"
      terraformVersion: "1.5.7"

  compute:
    name: "EC2 Instances"
    vcs:
      type: terraform
      repository: "git@github.com:myorg/infrastructure.git"
      path: "terraform/compute"
      terraformVersion: "RESOLVE_FROM_TERRAFORM_CODE"
      sshKeys:
        - id: "ssh-key-123"
          name: "Deploy Key"
    needs:
      - networking

Mixed Workflow with Settings

Combine template references and inline VCS with global settings.

env0.workflow.yaml

settings:
  environmentRemovalStrategy: detach

environments:
  infra:
    name: "Base Infrastructure"
    templateName: "terraform-aws-base"
    revision: "v2.0.0"

  app:
    name: "Application"
    vcs:
      type: helm
      repository: "https://github.com/myorg/helm-charts"
      path: "charts/myapp"
    needs:
      - infra

  monitoring:
    name: "Monitoring Stack"
    templateName: "prometheus-grafana"
    needs:
      - infra
    disabled: false

Workflow with Variable Interpolation

Use environment variables to conditionally disable sub-environments.

env0.workflow.yaml

environments:
  vpc:
    name: "VPC and Network"
    templateName: "VPC"

  db:
    name: "Database"
    templateName: "DB"
    requiresApproval: true
    needs:
      - vpc

  eks:
    name: "EKS Cluster"
    templateName: "EKS"
    needs:
      - vpc

  billing-service:
    name: "Billing Service"
    templateName: "Billing Service"
    disabled: ${DISABLE_BILLING_SERVICE}
    needs:
      - db
      - eks

  config-service:
    name: "Configuration Service"
    templateName: "Configuration Service"
    revision: feature-branch
    disabled: ${DISABLE_CONFIG_SERVICE}
    needs:
      - db
      - eks

Use variable interpolation with the disabled property to enable partial workflow deployments based on environment variables.
