Add support for easier YAML loading.

[brendandburns]

Closes #170

@kondapally1989 @zysimplelife @lwander

Code now looks like:

V1Pod pod = (V1Pod) Yaml.load(new File("my-file.yaml"));

[brendandburns]

Merging because of a lack of reviews...

How to load in to an specific namespace ??

[brendandburns]

You need the namespace in the Yaml file metadata: namespace: Foo ...

V1Pod pod = (V1Pod) Yaml.load(new File("my-file.yaml"));
After this how can we feed this pod to kubernetes cluster ?
Using this :
V1Pod result = apiInstance.createNamespacedPod(namespace, body, pretty); ??

[brendandburns]

Yes.

V1Pod pod = (V1Pod) Yaml.load(new File("my-file.yaml"));
Error : Cannot resolve method 'load(java.io.File)'

import for yaml :
import org.yaml.snakeyaml.Yaml;

Any help ??

[karthikkondapally]

@mmmaks
can you paste entire error?
and did you pull latest code and generate jar

[karthikkondapally]

import for YAML:
import io.kubernetes.client.util.Yaml;

[mmmaks]

import io.kubernetes.client.util.Yaml;
It shows : cannot resolve symbol 'Yaml'

pom :

<dependency>
    <groupId>io.kubernetes</groupId>
    <artifactId>client-java</artifactId>
    <version>LATEST</version>
    <scope>compile</scope>
</dependency>

[karthikkondapally]

i think maven release doesn't contain this pull request yet
see #210.
either you have to wait for new release or clone this repo and generate jar.

[mmmaks]

There is no single argument constructor in Quantity.
So when I am trying give resource limits as :

resources:
   requests:
     cpu: 1
     memory: 2Gi
   limits:
     cpu: 1
     memory: 2Gi

It shows :
org.yaml.snakeyaml.error.YAMLException: No single argument constructor found for class io.kubernetes.client.custom.Quantity : null

[mmmaks]

Also, while creating Kubernetes Job, with yaml :
kind: Job
apiVersion: batch/v1
Error :

java.io.IOException: Unknown apiVersionKind: batch/v1/Job known kinds are:

and then a list of known kinds.
But here shows apiVersion: batch/v1 for job.

Also, when I try to create Job with yaml :
kind: Job
apiVersion: v1

Error :
io.kubernetes.client.ApiException: Bad Request at io.kubernetes.client.ApiClient.handleResponse(ApiClient.java:882) at io.kubernetes.client.ApiClient.execute(ApiClient.java:798) at io.kubernetes.client.apis.BatchV1Api.createNamespacedJobWithHttpInfo(BatchV1Api.java:160) at io.kubernetes.client.apis.BatchV1Api.createNamespacedJob(BatchV1Api.java:144)

please help !!

[karthikkondapally]

@mmmaks some mappings of Kind and apiVersion are missing. getApiGroupVersion() doesn't contain V1Job -> batch/v1
I will try to add few mapping and create pull request.

can you open issue instead of adding comments on pull request. it will be helpful/visible to others and they may quickly identify the issue

[karthikkondapally]

on a 2nd look, it seems HashMap classes is never loaded with key batch/v1/Job because pojo/DTO for job is V1Job.java but not BatchV1Job.java
this will also apply to:
Job, JobCondition, JobList, JobSpec, JobStatus
