title: Clock Web Worker Pattern
nav_text: Clock Web Worker
categories: patterns
---

A common pattern is to use the same code to run different types of processes like clock, web, worker. Kubes is flexible enough to support this pattern.

Note, often the clock process is also called a scheduler.

## Structure

Here's a structure that achieves this pattern with Kubes:

    .kubes/resources
    ├── clock
    │   └── deployment.rb
    ├── web
    │   ├── deployment.rb
    │   └── service.rb
    └── worker
        └── deployment.rb

## Source Code

.kubes/resources/demo-clock/deployment.rb

```ruby
name "demo-clock"
namespace "default"
labels(role: "web")

replicas 1
image built_image # IE: user/demo-clock:kubes-2020-06-13T19-55-16-43afc6e
command "bin/clock"
```

.kubes/resources/web/deployment.rb

```ruby
name "demo-web"
namespace "default"
labels(role: "web")

replicas 1
image built_image # IE: user/demo-clock:kubes-2020-06-13T19-55-16-43afc6e
```

.kubes/resources/demo-worker/deployment.rb

```ruby
name "demo-worker"
namespace "default"
labels(role: "web")

replicas 2
image built_image # IE: user/demo-clock:kubes-2020-06-13T19-55-16-43afc6e
command "bin/worker"
```

## Deploy All-At-Once

To deploy all 3 process types:

    kubes deploy

## Deploy Selectively

To deploy selectively:

    kubes deploy clock
    kubes deploy web
    kubes deploy worker
