Examples with Service io.fabric8.patch.Service used on opensource projects

Example 1 with Service

use of io.fabric8.patch.Service in project che by eclipse.

the class OpenShiftConnector method createContainer.

/**
     * @param createContainerParams
     * @return
     * @throws IOException
     */
@Override
public ContainerCreated createContainer(CreateContainerParams createContainerParams) throws IOException {
    String containerName = KubernetesStringUtils.convertToContainerName(createContainerParams.getContainerName());
    String workspaceID = getCheWorkspaceId(createContainerParams);
    // Generate workspaceID if CHE_WORKSPACE_ID env var does not exist
    workspaceID = workspaceID.isEmpty() ? KubernetesStringUtils.generateWorkspaceID() : workspaceID;
    // imageForDocker is the docker version of the image repository. It's needed for other
    // OpenShiftConnector API methods, but is not acceptable as an OpenShift name
    String imageForDocker = createContainerParams.getContainerConfig().getImage();
    // imageStreamTagName is imageForDocker converted into a form that can be used
    // in OpenShift
    String imageStreamTagName = KubernetesStringUtils.convertPullSpecToTagName(imageForDocker);
    // imageStreamTagName is not enough to fill out a pull spec; it is only the tag, so we
    // have to get the ImageStreamTag from the tag, and then get the full ImageStreamTag name
    // from that tag. This works because the tags used in Che are unique.
    ImageStreamTag imageStreamTag = getImageStreamTagFromRepo(imageStreamTagName);

        String deploymentName = createOpenShiftDeployment(workspaceID, dockerPullSpec, containerName, exposedPorts, envVariables, volumes, runContainerAsRoot);
        containerID = waitAndRetrieveContainerID(deploymentName);
        if (containerID == null) {

        }
    } catch (IOException e) {
        // Make sure we clean up deployment and service in case of an error -- otherwise Che can end up
        // in an inconsistent state.
        LOG.info("Error while creating Pod, removing deployment");
        String deploymentName = CHE_OPENSHIFT_RESOURCES_PREFIX + workspaceID;
        cleanUpWorkspaceResources(deploymentName);

    }
    Exchange ex = template.request("direct:getServices", new Processor() {

        }
    });
    Service result = ex.getOut().getBody(Service.class);
    assertNull(result);
}

Example 5 with Service
