Depot CI

Depot CI is a programmable CI system for engineers and agents. Workflows in Depot CI run entirely on Depot compute with built-in job visibility, debuggability, and control. GitHub Actions is the first syntax Depot CI supports: migrate your existing GitHub Actions workflows, and get fast, reliable runs on optimized infrastructure.

Architecture

Three subsystems: compute (provisions and executes work), orchestrator (schedules multi-step workflows, handles dependencies), GitHub Actions parser (translates Actions YAML into orchestrator workflows). The system is fully programmable.

Org Context Check for Multi-Org Users

If a user belongs to multiple organizations, before setup/migration or if CI commands can't find expected workflows, verify Depot org context first:

# Check current org ID
depot org show

# List orgs the user belongs to
depot org list

# Option A: switch default org for this shell/session
depot org switch <org-id>

# Option B: keep current org and target explicitly per command
depot ci run --org <org-id> --workflow .depot/workflows/ci.yml

Use --org <org-id> when the workflow/repo lives in a different org than the current default.

Getting Started

1. Install the Depot Code Access GitHub App

Depot dashboard → Settings → GitHub Code Access → Connect to GitHub

(If you've used Claude Code on Depot, this may already be installed.)

2. Migrate workflows

depot ci migrate

This interactive wizard:

  1. Checks that the Depot Code Access app is installed and configured.
  2. Discovers all workflows in .github/workflows/ and analyzes each for Depot CI compatibility.
  3. Copies selected workflows to .depot/workflows/ with inline corrections and comments.
  4. Copies local actions from .github/actions/ to .depot/actions/.
  5. Detects secrets and variables referenced in workflows and prints next steps for importing them.

Your .github/ directory is untouched, so workflows run in both GitHub and Depot simultaneously.

Warning: Workflows that cause side effects (deploys, artifact updates) will execute twice.

Migrate subcommands

The migrate command can also be run as individual steps:

# Check installation and auth
depot ci migrate preflight

# Copy and transform workflows to .depot/workflows/
depot ci migrate workflows

# Import GitHub Actions secrets and variables into Depot CI
depot ci migrate secrets-and-vars

Migrate flags

Flag Description
-y, --yes Non-interactive, migrate all workflows
--overwrite Overwrite existing .depot/ directory
--org <id> Organization ID (required if multiple orgs)
--token <token> Depot API token

3. Import secrets and variables

depot ci migrate secrets-and-vars

This creates and runs a one-shot GitHub Actions workflow on a temporary branch that reads your existing secrets and variables and imports them into Depot CI. The branch is safe to delete afterwards.

You can also add secrets and variables manually with depot ci secrets add and depot ci vars add (see below).

Migrate Secrets-and-Vars flags

Flag Description
-y, --yes Skip preview and confirmation prompts
--branch Override the branch name used for the migration workflow
--secrets <name> Secret name to include; can be repeated to select multiple. Omit to include all.
--vars <name> Variable name to include; can be repeated to select multiple. Omit to include all.
--org <id> Organization ID (required if multiple orgs)
--token <token> Depot API token

4. Manual setup (without migrate command)

Create .depot/workflows/ and .depot/actions/ directories manually. Copy workflow files from .github/workflows/. Configure secrets via the CLI.

Managing Secrets

Secrets can be org-wide or scoped to a specific repository. Repository-scoped secrets override org-wide secrets with the same name.

# Add (prompts for value securely if --value omitted)
depot ci secrets add SECRET_NAME
depot ci secrets add SECRET_NAME --value "$NPM_TOKEN" --description "NPM auth token"

# Add repo-scoped secret
depot ci secrets add SECRET_NAME --repo owner/repo --value "$NPM_TOKEN"

# List (names and metadata only, no values)
depot ci secrets list
depot ci secrets list --output json
depot ci secrets list --repo owner/repo    # Also show repo-specific secrets

# Remove
depot ci secrets remove SECRET_NAME
depot ci secrets remove SECRET_NAME --force          # Skip confirmation
depot ci secrets remove SECRET_NAME --repo owner/repo  # Remove repo-scoped secret

Credential Safety Guardrails

Treat credentials as sensitive input and never echo them back in outputs.

  • For non-interactive flows, pass secret values via environment variables (for example: --value "$NPM_TOKEN"), not literals.
  • Prefer interactive secret prompts (depot ci secrets add SECRET_NAME) over command-line secret values.
  • Do not hardcode secrets or tokens in commands, scripts, workflow YAML, logs, or examples.
  • Use CI secret stores for DEPOT_TOKEN and other credentials; pass at runtime only.
  • Avoid force/non-interactive destructive flags unless explicitly requested by the user.
  • Before running credential-affecting commands, confirm scope (org, repo, workflow) and intended target.

Managing Variables

Non-secret config values accessible as ${{ vars.VARIABLE_NAME }}. Unlike secrets, values can be read back. Variables can be org-wide or scoped to a specific repository, just like secrets.

# Add org-wide variable
depot ci vars add VAR_NAME --value "some-value"

# Add repo-scoped variable
depot ci vars add VAR_NAME --value "some-value" --repo owner/repo

# List
depot ci vars list
depot ci vars list --output json
depot ci vars list --repo owner/repo    # Also show repo-specific variables

# Remove
depot ci vars remove VAR_NAME
depot ci vars remove VAR_NAME --force
depot ci vars remove VAR_NAME --repo owner/repo

Running Workflows

# Run a workflow
depot ci run --workflow .depot/workflows/ci.yml

# Run a workflow in a specific org (for multi-org users)
depot ci run --org <org-id> --workflow .depot/workflows/ci.yml

# Run specific jobs only
depot ci run --workflow .depot/workflows/ci.yml --job build --job test

# Run a job and connect via SSH
depot ci run --workflow .depot/workflows/ci.yml --job build --ssh

# Debug with tmate session after step N (requires single --job)
depot ci run --workflow .depot/workflows/ci.yml --job build --ssh-after-step 3

The CLI auto-detects uncommitted changes vs. the default branch, uploads a patch to Depot Cache, and injects a step to apply it after checkout, so your local working state runs without needing a push.

Use --ssh or --ssh-after-step on depot ci run to start a debug session when launching a new run. Use depot ci ssh (below) to connect to an already-running job.

Custom Images

Build a custom image once and reuse it across jobs to skip repeated setup steps.

Build the image

Use depot/snapshot-action (Depot CI only, not compatible with GitHub Actions):

jobs:
  build-image:
    runs-on: depot-ubuntu-latest
    steps:
      - run: sudo apt-get install -y your-tool
      - uses: depot/snapshot-action@v1
        with:
          image: <org-id>.registry.depot.dev/my-ci-image:latest

Use the image

Reference it in any Depot CI job with the runs-on object syntax:

jobs:
  test:
    runs-on:
      size: 2x8
      image: <org-id>.registry.depot.dev/my-ci-image:latest
    steps:
      - uses: actions/checkout@v4

Available sizes: 2x8, 4x16, 8x32, 16x64, 32x128 (CPUs x RAM in GB).

Constraints: Images get pushed to and must be pulled from the Depot registry (registry.depot.dev), external registries are not supported.

Parallel Steps

Depot CI supports running steps concurrently within a single job using parallel: blocks. This reduces job duration to the slowest branch rather than the sum of all steps. This is a Depot CI-specific feature, it is not compatible with GitHub Actions runners.

Use parallel: inside steps: with individual steps or sequential: groups. Each branch starts from the same job state; step outputs, environment variable and $GITHUB_PATH changes from all branches are merged back when the block completes.

# Run lint, typecheck, and tests concurrently
steps:
  - uses: actions/checkout@v4
  - name: Install dependencies
    run: pnpm install
  - parallel:
      - name: Lint
        run: pnpm lint
      - name: Typecheck
        run: pnpm type-check
      - name: Test
        run: pnpm test

Use sequential: inside parallel: to group steps that must run in order within one branch:

- parallel:
    - sequential:
        - name: Build
          run: npm run build
        - name: Test
          run: npm test
    - name: Lint
      run: npm run lint

Control failure behavior with fail-fast:. Defaults to true which cancels remaining steps in a parallel block. false will instead let all steps in the parallel block run to completion:

- fail-fast: false
  parallel:
    - name: Lint
      run: pnpm lint
    - name: Typecheck
      run: pnpm type-check

Limitations:

  • parallel: cannot be nested inside another parallel: (use sequential: inside parallel: instead)
  • Step id values must be unique across the entire job (including even in different parallel blocks)

SSH into Running Jobs

Connect to a running CI job via interactive terminal for debugging.

# Connect directly using a job ID
depot ci ssh <job-id>

# Connect to a specific job in a run
depot ci ssh <run-id> --job build

# Auto-select job when there's only one
depot ci ssh <run-id>

# Print SSH connection details for automation
depot ci ssh <run-id> --info --output json

The command waits up to 5 minutes for the job sandbox to be provisioned if it hasn't started yet.

SSH flags

Flag Description
--job <key> Job key to connect to (required for multi-job runs)
--info Print SSH details instead of connecting interactively
-o, --output Output format for --info (json)
--org <id> Organization ID
--token <token> Depot API token

Checking Status and Logs

# Check run status (shows workflows -> jobs -> attempts hierarchy)
depot ci status <run-id>

# Fetch logs (accepts run ID, job ID, or attempt ID)
depot ci logs <run-id>
depot ci logs <attempt-id>

# Specify a job when the run has multiple jobs
depot ci logs <run-id> --job test

# Disambiguate when multiple workflows share the same job key
depot ci logs <run-id> --job build --workflow ci.yml

When given a run or job ID, depot ci logs resolves to the latest attempt automatically.

Logs flags

Flag Description
--job <key> Job key to select (required when run has multiple jobs)
--workflow <path> Workflow path to filter jobs (for example, ci.yml)
--org <id> Organization ID
--token <token> Depot API token

Listing Runs and Triage Flow

depot ci run list is the primary entrypoint for debugging active/recent CI activity across workflows.

# List runs (defaults to queued + running)
depot ci run list

# Filter by status (repeatable)
depot ci run list --status failed
depot ci run list --status finished --status failed

# Limit number of results
depot ci run list -n 5

# Machine-readable output for tooling/agents
depot ci run list --output json

run list flags

Flag Description
-n <int> Number of runs to return (default 50)
--status <name> Filter by status; repeatable: queued, running, finished, failed, cancelled
-o, --output Output format (json)
--org <id> Organization ID
--token <token> Depot API token

Debugging failed runs

# Find failed runs
depot ci run list --status failed -n 10

# Pull logs directly (auto-selects job if only one)
depot ci logs <run-id>

# Specify job when there are multiple
depot ci logs <run-id> --job build

# Use status to inspect the full workflow/job/attempt hierarchy when needed
depot ci status <run-id>

Use --output json on depot ci run list for machine-readable output.

Not Supported

  • Cross-repo reusable workflows: uses referencing workflows in other repositories is not supported. Local reusable workflows work.
  • Fork-triggered PRs: pull_request and pull_request_target from forks not supported yet
  • Non-Ubuntu runner labels: all non-Depot labels silently treated as depot-ubuntu-latest (no error, runs on Ubuntu)
  • Deployment environments: the environment field is not supported
  • GitHub-specific event triggers: release, issues, issue_comment, deployment, create, delete, and others

Runner labels

Depot CI supports these runner labels:

Label CPUs RAM
depot-ubuntu-latest 2 8 GB
depot-ubuntu-24.04 2 8 GB
depot-ubuntu-24.04-4 4 16 GB
depot-ubuntu-24.04-8 8 32 GB
depot-ubuntu-24.04-16 16 64 GB
depot-ubuntu-24.04-32 32 128 GB

Any label Depot CI can't parse is silently treated as depot-ubuntu-latest.

Common Mistakes

Mistake Fix
Removing .github/workflows/ after migration Keep them during transition to verify Depot CI parity
Using cross-repo reusable workflows Not supported yet, inline the workflow or copy it locally
Setting secrets without --repo when needed Use --repo owner/repo for repo-specific secret overrides
Running in the wrong org context Check depot org show, list with depot org list, then switch org or pass --org <id>
Forgetting --org flag with multiple orgs Migration or run commands may miss the expected repo/workflow; specify --org <id>
Workflows with runs-on: windows-latest Treated as depot-ubuntu-latest, may fail
