GitOps with TrueFoundry

Set up GitOps-style deployments with TrueFoundry. Store deployment configurations as YAML specs in Git and auto-deploy on push using

tfy apply

in CI/CD pipelines.

When to Use

Set up automated Git-based deployments with

tfy apply

. Store TrueFoundry YAML specs in Git and auto-deploy on push/merge via CI/CD pipelines.

Prerequisites

Always verify before setting up GitOps:

Credentials —
```
TFY_BASE_URL
```
and
```
TFY_API_KEY
```
must be set (env or
```
.env
```
)
TrueFoundry CLI —
```
tfy
```
CLI must be available in the CI/CD environment (installed via
```
pip install truefoundry
```
)
Git repository — A Git repo to store deployment specs

For credential check commands and .env setup, see

references/prerequisites.md

. Use the

status

skill to verify connection before proceeding.

How GitOps Works with TrueFoundry

GitOps treats Git as the single source of truth for deployment configurations. The workflow is:

Store specs in Git — All TrueFoundry resource YAML specs live in the repository
Review via pull requests — Changes are reviewed before merging, with
```
tfy apply --dry-run
```
validating specs in CI
Auto-deploy on merge — When specs are merged to the default branch,
```
tfy apply
```
deploys them automatically
Full audit trail — Git history tracks every change, who made it, and when

Repository Organization

Organize your repo with directories for each resource type:

truefoundry-configs/
├── clusters/
│   └── my-cluster/
│       ├── dev-workspace/
│       │   ├── my-api-service.yaml
│       │   ├── my-worker.yaml
│       │   └── my-llm.yaml
│       ├── staging-workspace/
│       │   ├── my-api-service.yaml
│       │   └── my-worker.yaml
│       └── prod-workspace/
│           ├── my-api-service.yaml
│           └── my-worker.yaml
├── gateway/
│   ├── models.yaml
│   ├── guardrails.yaml
│   └── tool-servers.yaml
├── integrations/
│   └── custom-integration.yaml
├── teams/
│   └── my-team.yaml
└── virtualaccounts/
    └── my-account.yaml

Key Principles

One YAML file per resource — Each TrueFoundry resource (service, job, model, etc.) gets its own file
Filename matches resource name — The YAML filename should match the
```
name
```
field inside the spec
Separate directories per workspace — Keep dev, staging, and prod configs in separate directories
Extract specs from the UI — Use "Edit -> Apply Using YAML" in the TrueFoundry dashboard to get the YAML spec for any existing resource

Manifest File Structure

Each YAML spec follows the standard TrueFoundry manifest format. For example, a service spec:

yaml

type: service
name: my-api-service
image:
  type: image
  image_uri: my-registry/my-app:latest
  command: uvicorn main:app --host 0.0.0.0 --port 8000
ports:
  - port: 8000
    expose: true
    protocol: TCP
    app_protocol: http
    host: my-api-dev.ml.example.truefoundry.cloud
workspace_fqn: my-cluster:dev-workspace
env:
  APP_ENV: development
  LOG_LEVEL: debug
replicas:
  min: 1
  max: 3
resources:
  cpu_request: 0.5
  cpu_limit: 1.0
  memory_request: 512
  memory_limit: 1024

Environment-Specific Configs (Dev / Staging / Prod)

Maintain separate YAML files per environment. Common differences:

Setting	Dev	Staging	Prod
`replicas.min`	1	1	2+
`replicas.max`	1	3	10+
`resources.cpu_request`	0.25	0.5	1.0+
`resources.memory_request`	256	512	1024+
`env.LOG_LEVEL`	debug	info	warn
`ports.host`	`-dev.`	`-staging.`	`-prod.`
`workspace_fqn`	`cluster:dev-ws`	`cluster:staging-ws`	`cluster:prod-ws`

Example directory layout:

clusters/my-cluster/
├── dev-workspace/
│   └── my-service.yaml       # min resources, 1 replica, debug logging
├── staging-workspace/
│   └── my-service.yaml       # moderate resources, autoscaling, info logging
└── prod-workspace/
    └── my-service.yaml        # full resources, HA replicas, warn logging

Using

tfy apply

in CI/CD Pipelines

The

tfy apply

command is the core of GitOps with TrueFoundry.

Basic Usage

bash

# Install TrueFoundry CLI (pin version range to prevent supply-chain attacks)
pip install 'truefoundry>=0.5.0,<1.0'

# Authenticate (uses TFY_HOST and TFY_API_KEY env vars)
# TFY_HOST is the TrueFoundry platform URL (same as TFY_BASE_URL)

# Dry run — validate without deploying
tfy apply --file path/to/spec.yaml --dry-run

# Apply — deploy the spec
tfy apply --file path/to/spec.yaml

Applying Multiple Files

To apply all changed files in a CI/CD pipeline, detect which files were modified in the commit or PR:

bash

# Apply each changed YAML file
while IFS= read -r file; do
  [ -z "$file" ] && continue
  echo "Applying $file..."
  tfy apply --file "$file"
done < <(git diff --name-only HEAD~1 HEAD -- '*.yaml')

Handling Deleted Files

When a YAML spec file is deleted from the repo, the corresponding resource should be removed. The CI/CD pipeline should detect deleted files and handle them:

bash

# Warn about deleted files
while IFS= read -r file; do
  [ -z "$file" ] && continue
  echo "WARNING: $file was deleted. Remove the resource manually from the TrueFoundry dashboard."
done < <(git diff --name-only --diff-filter=D HEAD~1 HEAD -- '*.yaml')

CI/CD Integration

For complete workflow files for each CI provider:

GitHub Actions: See references/gitops-github-actions.md -- PR validation (dry-run) and merge-to-deploy workflows, plus required secrets setup.
GitLab CI: See references/gitops-gitlab-ci.md -- validate and deploy stages with caching.
Bitbucket Pipelines: See references/gitops-bitbucket-pipelines.md -- PR validation and branch-based deploy.

All providers require

TFY_HOST

and

TFY_API_KEY

as repository secrets/variables.

Step-by-Step: Setting Up GitOps (Summary)

Verify TrueFoundry connection — Use the
```
status
```
skill to confirm credentials
Create the repo structure — Set up directories for your resource types (clusters, gateway, etc.)
Export existing specs — In the TrueFoundry dashboard, go to each resource -> Edit -> Apply Using YAML. Save each spec as a YAML file in the repo.
Add CI/CD workflows — Copy the appropriate workflow files for your CI provider (see above)
Set repository secrets — Add
```
TFY_HOST
```
and
```
TFY_API_KEY
```
as secrets/variables in your CI provider
Test with a dry run — Open a PR with a small change to verify the validation pipeline works
Merge and deploy — Merge the PR and confirm the apply pipeline deploys successfully

</instructions>

<success_criteria>

Success Criteria

The user has a Git repository with TrueFoundry YAML specs organized by environment (dev/staging/prod)
The CI/CD pipeline validates specs on pull requests using
```
tfy apply --dry-run
```
The CI/CD pipeline auto-deploys specs on merge to the default branch using
```
tfy apply
```
The agent has provided the user with the correct CI workflow files for their CI provider (GitHub Actions, GitLab CI, or Bitbucket Pipelines)
Repository secrets (
```
TFY_HOST
```
,
```
TFY_API_KEY
```
) are configured in the CI provider
The user can verify the pipeline works by opening a PR with a small YAML change and seeing validation pass

</success_criteria>

Error Handling

tfy apply Failed — Invalid Spec

tfy apply returned a validation error.
Check:
- YAML syntax is valid (no tabs, proper indentation)
- Required fields are present (type, name, workspace_fqn)
- Resource references exist (workspace, secrets, etc.)
Run: tfy apply --file spec.yaml --dry-run

tfy apply Failed — Authentication Error

401 Unauthorized from tfy apply.
Check:
- TFY_HOST is set correctly (the platform URL, e.g., https://your-org.truefoundry.cloud)
- TFY_API_KEY is valid and not expired
- Secrets are configured correctly in your CI provider

tfy apply Failed — Workspace Not Found

Workspace FQN in the spec does not exist.
Check:
- workspace_fqn field matches an existing workspace
- Use the workspaces skill to list available workspaces

CI Pipeline Not Triggering

Workflow not running on push/PR.
Check:
- File path filters match your YAML file locations
- Branch filters match your default branch name
- CI provider secrets are set (TFY_HOST, TFY_API_KEY)

Filename / Spec Name Mismatch

The YAML filename should match the 'name' field inside the spec.
Example: my-service.yaml should contain name: my-service
This is a convention for clarity — tfy apply uses the internal name, not the filename.
