Deployment Management

Manage LangGraph Cloud deployments using the Langstar CLI with focus on test deployment cleanup, filtering, and environment handling.

Core Capabilities

• List deployments with filtering by name, status, or type
• Filter test deployments by pattern (test-, langstar-test-)
• Delete deployments individually or in batch
• Handle environment variables automatically (check first, source if needed)
• Interactive confirmation for destructive operations

Prerequisites

Required Credentials

LangSmith API:

• LANGSMITH_API_KEY - API key for Control Plane authentication
• LANGSMITH_WORKSPACE_ID - Workspace ID (optional if using organization)

Location: /workspace/.devcontainer/.env (gitignored)

CLI Tool

All operations use langstar graph commands:

• langstar graph list - List with filtering
• langstar graph get <id> - Get details
• langstar graph delete <id> - Delete deployment

Environment Handling

Critical Pattern: Check Before Sourcing

Always check if credentials exist BEFORE sourcing:

# ✅ CORRECT: Check first
if [ -z "$LANGSMITH_API_KEY" ] || [ -z "$LANGSMITH_WORKSPACE_ID" ]; then
    echo "📋 Sourcing credentials..."
    source /workspace/.devcontainer/.env
fi

# Verify (never expose actual values)
[ -n "$LANGSMITH_API_KEY" ] && echo "✓ LANGSMITH_API_KEY set" || echo "❌ Not set"

Security Rule: Never expose credential values:

# ❌ WRONG: Exposes sensitive data
echo "Key: $LANGSMITH_API_KEY"

# ✅ CORRECT: Only check presence
[ -n "$LANGSMITH_API_KEY" ] && echo "Set" || echo "Not set"

Core Workflows

Workflow 1: List All Deployments

# Source credentials if needed
if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

# List deployments
langstar graph list --limit 20

Output:

┌────────────────────────────────┬──────────────────────┬────────┐
│ Name                           │ ID                   │ Status │
├────────────────────────────────┼──────────────────────┼────────┤
│ langstar-test-1763668434       │ 97dff6a5-f844-472... │ Ready  │
│ test-deployment-1763666536     │ 8665a96b-4620-407... │ Ready  │
└────────────────────────────────┴──────────────────────┴────────┘

Workflow 2: Filter by Name Pattern

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

# Filter by substring
langstar graph list --name-contains "test"
langstar graph list --name-contains "langstar-test"

# Combine filters
langstar graph list --name-contains "test" --status READY --limit 100

Workflow 3: Delete Single Deployment

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

# Interactive deletion (prompts for confirmation)
langstar graph delete <deployment-id>

# Skip confirmation
langstar graph delete <deployment-id> --yes

Workflow 4: Batch Cleanup of Test Deployments

Recommended: Interactive review before each deletion

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

# List test deployments to review
langstar graph list --name-contains "test" --limit 100

# Get deployment IDs
deployment_ids=$(langstar graph list --name-contains "test" --limit 100 --format json | jq -r '.resources[].id')

# Delete with confirmation for each
for id in $deployment_ids; do
    echo "Deployment: $id"
    langstar graph get "$id" | jq '{name, status, created_at}'
    read -p "Delete? (y/n): " confirm
    [ "$confirm" = "y" ] && langstar graph delete "$id" --yes && echo "✓ Deleted"
done

Alternative: Bulk deletion (use with caution)

See examples/batch-cleanup.md for non-interactive scripts.

Workflow 5: Filter by Status or Type

Available filters:

• Status: READY, AWAITING_DATABASE, UNUSED, AWAITING_DELETE
• Type: dev_free, dev, prod

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

# Filter by status
langstar graph list --status READY
langstar graph list --status UNUSED

# Filter by type
langstar graph list --deployment-type dev_free

# Combine filters
langstar graph list --name-contains "test" --status READY

CLI Reference

list - List deployments

langstar graph list [OPTIONS]

Options:
  -l, --limit <N>              Max to return [default: 20]
      --offset <N>             Pagination offset [default: 0]
      --name-contains <STR>    Filter by name substring
      --status <STATUS>        Filter: READY, AWAITING_DATABASE, UNUSED, etc.
      --deployment-type <TYPE> Filter: dev_free, dev, prod
  -f, --format <FORMAT>        Output: text, json [default: text]

get - Get deployment details

langstar graph get <DEPLOYMENT_ID>

Returns full deployment JSON including source config, status, timestamps, and revisions.

delete - Delete deployment

langstar graph delete <DEPLOYMENT_ID> [OPTIONS]

Options:
  -y, --yes    Skip confirmation prompt

Best Practices

Environment Variables

✅ Check before sourcing

if [ -z "$LANGSMITH_API_KEY" ]; then
    source /workspace/.devcontainer/.env
fi

✅ Never expose values

[ -n "$LANGSMITH_API_KEY" ] && echo "✓ Set" || echo "✗ Not set"

Deployment Deletion

✅ Review before deleting

# List first, verify, then delete
langstar graph list --name-contains "test"
langstar graph delete <id> --yes

✅ Interactive confirmation for batch

# Confirm each deletion
for id in $ids; do
    read -p "Delete $id? (y/n): " confirm
    [ "$confirm" = "y" ] && langstar graph delete "$id" --yes
done

Filtering

✅ Use specific patterns

# Specific reduces false matches
langstar graph list --name-contains "langstar-test-"

✅ Combine filters for precision

langstar graph list --name-contains "test" --status READY --deployment-type dev_free

Common Use Cases

Clean Up After Integration Tests

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi

# List test deployments
langstar graph list --name-contains "langstar-test"
langstar graph list --name-contains "test-deployment"

# Delete each
langstar graph delete <id-1> --yes
langstar graph delete <id-2> --yes

Find Unused Deployments

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi

# List unused
langstar graph list --status UNUSED --limit 100

# Review and delete manually
langstar graph list --limit 100 --format json | \
    jq '.resources[] | select(.status == "UNUSED") | {name, id, created_at, status}'

Filter by User/CI Pattern

# Source credentials
if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi

# Filter by username/CI prefix
langstar graph list --name-contains "alice-"
langstar graph list --name-contains "ci-build-"
langstar graph list --name-contains "pr-"

Troubleshooting

"Authentication failed"

Diagnosis:

[ -n "$LANGSMITH_API_KEY" ] && echo "Set" || echo "Not set"
[ -n "$LANGSMITH_WORKSPACE_ID" ] && echo "Set" || echo "Not set"

Solution:

source /workspace/.devcontainer/.env
# Verify
[ -n "$LANGSMITH_API_KEY" ] && echo "Set" || echo "Not set"

"Deployment not found"

Cause: Deployment deleted or incorrect ID.

Solution:

# Verify ID from list
langstar graph list --limit 100
langstar graph list --name-contains "<name-fragment>"

No Deployments Returned

Solution:

# Try without filters
langstar graph list --limit 100

# Try broader patterns
langstar graph list --name-contains "test"

Integration

With test-runner-worktree Skill

Clean up after test runs:

# After integration tests
cd /workspace/wip/<worktree-name>
if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi
langstar graph list --name-contains "langstar-test"

With git-worktrees Skill

Works in any location - credentials source the same:

# Works in main or worktree
cd /workspace
# or
cd /workspace/wip/claude-188-deployment-management

# Source once
if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi
langstar graph list

Quick Reference Templates

Environment Check

if [ -z "$LANGSMITH_API_KEY" ] || [ -z "$LANGSMITH_WORKSPACE_ID" ]; then
    source /workspace/.devcontainer/.env

List Test Deployments

if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi
langstar graph list --name-contains "test" --limit 100

Interactive Batch Delete

if [ -z "$LANGSMITH_API_KEY" ]; then source /workspace/.devcontainer/.env; fi
for id in $(langstar graph list --name-contains "test" --format json | jq -r '.resources[].id'); do
    langstar graph get "$id" | jq '{name, status, created_at}'
    read -p "Delete? (y/n): " confirm
    [ "$confirm" = "y" ] && langstar graph delete "$id" --yes
done
