🔄 Deployment Scripts Update Mechanism

Core Answer

✅ Yes, re-deploying automatically updates the plugin!

The deployment script uses a smart two-stage strategy:

1. 🔄 Try UPDATE First (if plugin exists)
2. 📝 Auto CREATE (if update fails — plugin doesn't exist)

Workflow Diagram

Run deploy script
    ↓
Read local code and metadata
    ↓
Send UPDATE request to OpenWebUI
    ↓
       ├─ HTTP 200 ✅
       │  └─ Plugin exists → Update successful!
       │
       └─ Other status codes (404, 400, etc.)
          └─ Plugin doesn't exist or update failed
             ↓
             Send CREATE request
             ↓
             ├─ HTTP 200 ✅
             │  └─ Creation successful!
             │
             └─ Failed
                └─ Display error message

Detailed Step-by-step

Step 1️⃣: Try UPDATE First

# Code location: deploy_filter.py line 220-230

update_url = "http://localhost:3000/api/v1/functions/id/{filter_id}/update"

response = requests.post(
    update_url,
    headers=headers,
    data=json.dumps(payload),
    timeout=10,
)

if response.status_code == 200:
    print(f"✅ Successfully updated '{title}' filter!")
    return True

What Happens:

• Send POST to /api/v1/functions/id/{filter_id}/update
• If returns HTTP 200, plugin exists and update succeeded
• Includes:
  • Complete latest code
  • Metadata (title, version, author, description, etc.)
  • Manifest information

Step 2️⃣: If UPDATE Fails, Try CREATE

# Code location: deploy_filter.py line 231-245

if response.status_code != 200:
    print(f"⚠️  Update failed with status {response.status_code}, "
          "attempting to create instead...")
    
    create_url = "http://localhost:3000/api/v1/functions/create"
    res_create = requests.post(
        create_url,
        headers=headers,
        data=json.dumps(payload),
        timeout=10,
    )
    
    if res_create.status_code == 200:
        print(f"✅ Successfully created '{title}' filter!")
        return True

What Happens:

• If update fails (HTTP ≠ 200), auto-attempt create
• Send POST to /api/v1/functions/create
• Uses same payload (code, metadata identical)
• If creation succeeds, first deployment to OpenWebUI

Real-world Scenarios

Scenario A: First Deployment

$ python deploy_async_context_compression.py

📦 Deploying filter 'Async Context Compression' (version 1.3.0)...
   File: .../async_context_compression.py
⚠️  Update failed with status 404, attempting to create instead...  ← First time, plugin doesn't exist
✅ Successfully created 'Async Context Compression' filter!         ← Creation succeeds

What Happens:

1. Try UPDATE → fails (HTTP 404 — plugin doesn't exist)
2. Auto-try CREATE → succeeds (HTTP 200)
3. Plugin created in OpenWebUI

---

Scenario B: Re-deploy After Code Changes

# Made first code change, deploying again
$ python deploy_async_context_compression.py

📦 Deploying filter 'Async Context Compression' (version 1.3.1)...
   File: .../async_context_compression.py
✅ Successfully updated 'Async Context Compression' filter!         ← Direct update!

What Happens:

1. Read modified code
2. Try UPDATE → succeeds (HTTP 200 — plugin exists)
3. Plugin in OpenWebUI updated to latest code
4. No need to restart OpenWebUI, takes effect immediately!

---

Scenario C: Multiple Fast Iterations

# 1st change
$ python deploy_async_context_compression.py
✅ Successfully updated 'Async Context Compression' filter!

# 2nd change
$ python deploy_async_context_compression.py
✅ Successfully updated 'Async Context Compression' filter!

# 3rd change
$ python deploy_async_context_compression.py
✅ Successfully updated 'Async Context Compression' filter!

# ... repeat infinitely ...

Characteristics:

• 🚀 Each update takes only 5 seconds
• 📝 Each is an incremental update
• ✅ No need to restart OpenWebUI
• 🔄 Can repeat indefinitely

What Gets Updated

Each deployment updates the following:

✅ Code — All latest Python code
✅ Version — Auto-extracted from docstring
✅ Title — Plugin display name
✅ Author Info — author, author_url
✅ Description — Plugin description
✅ Metadata — funding_url, openwebui_id, etc.

❌ Configuration NOT Overwritten — User's Valves settings in OpenWebUI stay unchanged

Version Number Management

Does Version Change on Update?

✅ Yes!

# docstring in async_context_compression.py

"""
title: Async Context Compression
version: 1.3.0
"""

Each deployment:

1. Script reads version from docstring
2. Sends this version in manifest to OpenWebUI
3. If you change version in code, deployment updates to new version

Best Practice:

# 1. Modify code
vim async_context_compression.py

# 2. Update version (in docstring)
# version: 1.3.0 → 1.3.1

# 3. Deploy
python deploy_async_context_compression.py

# Result: OpenWebUI shows version 1.3.1

Deployment Failure Cases

Case 1: Network Error

❌ Connection error: Could not reach OpenWebUI at localhost:3000
   Make sure OpenWebUI is running and accessible.

Cause: OpenWebUI not running or wrong port
Solution: Check if OpenWebUI is running

Case 2: Invalid API Key

❌ Failed to update or create. Status: 401
   Error: {"error": "Unauthorized"}

Cause: API key in .env is invalid or expired
Solution: Update api_key in .env file

Case 3: Server Error

❌ Failed to update or create. Status: 500
   Error: Internal server error

Cause: OpenWebUI server internal error
Solution: Check OpenWebUI logs

Setting Version Numbers — Best Practices

Semantic Versioning

Follow MAJOR.MINOR.PATCH format:

"""
version: 1.3.0
  │  │  │
  │  │  └─ PATCH: Bug fixes (1.3.0 → 1.3.1)
  │  └────── MINOR: New features (1.3.0 → 1.4.0)
  └───────── MAJOR: Breaking changes (1.3.0 → 2.0.0)
"""

Examples:

# Bug fix (PATCH)
version: 1.3.0 → 1.3.1

# New feature (MINOR)
version: 1.3.0 → 1.4.0

# Major update (MAJOR)
version: 1.3.0 → 2.0.0

Complete Iteration Workflow

# 1. First deployment
cd scripts
python deploy_async_context_compression.py
# Result: Plugin created (first time)

# 2. Modify code
vim ../plugins/filters/async-context-compression/async_context_compression.py
# Edit code...

# 3. Deploy again (auto-update)
python deploy_async_context_compression.py
# Result: Plugin updated (takes effect immediately, no OpenWebUI restart)

# 4. Repeat steps 2-3 indefinitely
# Modify → Deploy → Test → Improve → Repeat

Benefits of Auto-update

Benefit	Details
⚡ Fast Iteration	Code change → Deploy (5s) → Test, no waiting
🔄 Auto-detection	No manual decision between create/update
📝 Version Management	Version auto-extracted from code
✅ No Restart Needed	OpenWebUI runs continuously, config stays same
🛡️ Safe Updates	User settings (Valves) never overwritten

Disable Auto-update? ❌

Usually not needed because:

1. ✅ Updates are idempotent (same code deployed multiple times = no change)
2. ✅ User configuration not modified
3. ✅ Version numbers auto-managed
4. ✅ Failures auto-rollback

但如果真的需要控制，可以：

• 手动修改脚本 (修改 deploy_filter.py)
• 或分别使用 UPDATE/CREATE 的具体 API 端点

常见问题

Q: 更新是否会丢失用户的配置？

❌ 不会！
用户在 OpenWebUI 中设置的 Valves (参数配置) 会被保留。

Q: 是否可以回到旧版本？

✅ 可以！
修改代码中的 version 号为旧版本，然后重新部署。

Q: 更新需要多长时间？

⚡ 约 5 秒
包括: 读文件 (1s) + 发送请求 (3s) + 响应 (1s)

Q: 可以同时部署多个插件吗？

✅ 可以！

python deploy_filter.py async-context-compression
python deploy_filter.py folder-memory
python deploy_filter.py context_enhancement_filter

Q: 部署失败了会怎样？

✅ OpenWebUI 中的插件保持不变
失败不会修改已部署的插件。

---

总结: 部署脚本的更新机制完全自动化，开发者只需修改代码，每次运行 deploy_async_context_compression.py 就会自动：

1. ✅ 创建（第一次）或更新（后续）插件
2. ✅ 从代码提取最新的元数据和版本号
3. ✅ 立即生效，无需重启 OpenWebUI
4. ✅ 保留用户的配置不变

这使得本地开发和快速迭代变得极其流畅！🚀
