# Guestbook Example
|
||||||
|
|
||||||
|
Welcome to the Guestbook example. It shows you how to build and reuse
|
||||||
|
parameterized templates.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
First, make sure DM is installed in your Kubernetes cluster and that the
|
||||||
|
Guestbook example is deployed by following the instructions in the top level
|
||||||
|
[README.md](../../README.md).
|
||||||
|
|
||||||
|
## Understanding the Guestbook example
|
||||||
|
|
||||||
|
Let's take a closer look at the configuration used by the Guestbook example.
|
||||||
|
|
||||||
|
### Replicated services
|
||||||
|
|
||||||
|
The typical design pattern for microservices in Kubernetes is to create a
|
||||||
|
replication controller and a service with the same selector, so that the service
|
||||||
|
exposes ports from the pods managed by the replication controller.
|
||||||
|
|
||||||
|
We have created a parameterized template for this kind of replicated service
|
||||||
|
called [Replicated Service](../../templates/replicatedservice/v1), and we use it
|
||||||
|
three times in the Guestbook example.
|
||||||
|
|
||||||
|
The template is defined by a
|
||||||
|
[Python script](../../templates/replicatedservice/v1/replicatedservice.py). It
|
||||||
|
also has a [schema](../../templates/replicatedservice/v1/replicatedservice.py.schema).
|
||||||
|
Schemas are optional. If provided, they are used to validate template invocations
|
||||||
|
that appear in configurations.
|
||||||
|
|
||||||
|
For more information about templates and schemas, see the
|
||||||
|
[design document](../../docs/design/design.md#templates).
|
||||||
|
|
||||||
|
### The Guestbook application
|
||||||
|
The Guestbook application consists of 2 microservices: a front end and a Redis
|
||||||
|
cluster.
|
||||||
|
|
||||||
|
#### The front end
|
||||||
|
|
||||||
|
The front end is a replicated service with 3 replicas:
|
||||||
|
|
||||||
|
```
|
||||||
|
- name: frontend
|
||||||
|
type: https://raw.githubusercontent.com/kubernetes/deployment-manager/master/templates/replicatedservice/v1/replicatedservice.py
|
||||||
|
properties:
|
||||||
|
service_port: 80
|
||||||
|
container_port: 80
|
||||||
|
external_service: true
|
||||||
|
replicas: 3
|
||||||
|
image: gcr.io/google_containers/example-guestbook-php-redis:v3
|
||||||
|
```
|
||||||
|
|
||||||
|
(Note that we use the URL for a specific version of the template replicatedservice.py,
|
||||||
|
not just the template name.)
|
||||||
|
|
||||||
|
#### The Redis cluster
|
||||||
|
|
||||||
|
The Redis cluster consists of two replicated services: a master with a single replica
|
||||||
|
and the slaves with 2 replicas. It's defined by [this template](../../templates/redis/v1/redis.jinja),
|
||||||
|
which is a [Jinja](http://jinja.pocoo.org/) file with a [schema](../../templates/redis/v1/redis.jinja.schema).
|
||||||
|
|
||||||
|
```
|
||||||
|
{% set REDIS_PORT = 6379 %}
|
||||||
|
{% set WORKERS = properties['workers'] or 2 %}
|
||||||
|
|
||||||
|
resources:
|
||||||
|
- name: redis-master
|
||||||
|
type: https://raw.githubusercontent.com/kubernetes/deployment-manager/master/templates/replicatedservice/v1/replicatedservice.py
|
||||||
|
properties:
|
||||||
|
# This has to be overwritten since service names are hard coded in the code
|
||||||
|
service_name: redis-master
|
||||||
|
service_port: {{ REDIS_PORT }}
|
||||||
|
target_port: {{ REDIS_PORT }}
|
||||||
|
container_port: {{ REDIS_PORT }}
|
||||||
|
replicas: 1
|
||||||
|

|
||||||
|

|
||||||
|
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||

|
||||||
|

|
||||||
|

|
||||||
|
container_port: {{ REDIS_PORT }}
|
||||||
|
replicas: {{ WORKERS }}
|
||||||
|
container_name: worker
|
||||||
|
image: kubernetes/redis-slave:v2
|
||||||
|
# An example of how to specify env variables.
|
||||||
|
env:
|
||||||
|
- name: GET_HOSTS_FROM
|
||||||
|
value: env
|
||||||
|
- name: REDIS_MASTER_SERVICE_HOST
|
||||||
|
value: redis-master
|
||||||
|
```
|
||||||
|
|
||||||
|
### Displaying types
|
||||||
|
|
||||||
|
You can see both the both primitive types and the templates you've deployed to the
|
||||||
|
cluster using the `deployed-types` command:
|
||||||
|
|
||||||
|
```
|
||||||
|
dm deployed-types
|
||||||
|
|
||||||
|
["Service","ReplicationController","redis.jinja","https://raw.githubusercontent.com/kubernetes/deployment-manager/master/templates/replicatedservice/v1/replicatedservice.py"]
|
||||||
|
```
|
||||||
|
|
||||||
|
This output shows 2 primitive types (Service and ReplicationController), and 2
|
||||||
|
templates (redis.jinja and one imported from github named replicatedservice.py).
|
||||||
|
|
||||||
|
You can also see where a specific type is being used with the `deployed-instances` command:
|
||||||
|
|
||||||
|
```
|
||||||
|
dm deployed-instances Service
|
||||||
|
[{"name":"frontend-service","type":"Service","deployment":"guestbook4","manifest":"manifest-1446682551242763329","path":"$.resources[0].resources[0]"},{"name":"redis-master","type":"Service","deployment":"guestbook4","manifest":"manifest-1446682551242763329","path":"$.resources[1].resources[0].resources[0]"},{"name":"redis-slave","type":"Service","deployment":"guestbook4","manifest":"manifest-1446682551242763329","path":"$.resources[1].resources[1].resources[0]"}]
|
||||||
|
```
|
||||||
|
|
||||||
|
This output describes the deployment and manifest, as well as the JSON paths to
|
||||||
|
the instances of the type within the layout.
|
||||||
|
|
||||||
|
For more information about deployments, manifests and layouts, see the
|
||||||
|
[design document](../../docs/design/design.md#api-model).
