Example 4 with Pod

use of io.fabric8.kubernetes.api.model.Pod in project che by eclipse.

the class OpenShiftConnector method createContainer.

/**
     * @param createContainerParams
     * @return
     * @throws IOException
     */

    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 imageStreamTagPullSpec = imageStreamTag.getMetadata().getName();
    // Next we need to get the address of the registry where the ImageStreamTag is stored

        }
    } catch (IOException e) {

        // in an inconsistent state.

        throw e;
    }
    return new ContainerCreated(containerID, null);
}

Example 5 with Pod

use of io.fabric8.kubernetes.api.model.Pod in project che by eclipse.

the class OpenShiftConnector method commit.

/**
     * OpenShift does not support taking image snapshots since the underlying assumption
     * is that Pods are largely immutable (and so any snapshot would be identical to the image
     * used to create the pod). Che uses docker commit to create machine snapshots, which are
     * used to restore workspaces. To emulate this functionality in OpenShift, commit
     * actually creates a new ImageStreamTag by calling {@link OpenShiftConnector#tag(TagParams)}
     * named for the snapshot that would be created.
     *
     * @see DockerConnector#commit(CommitParams)
     */
@Override
public String commit(final CommitParams params) throws IOException {
    // e.g. machine_snapshot_mdkfmksdfm
    String repo = params.getRepository();
    // container ID
    String container = params.getContainer();
    Pod pod = getChePodByContainerId(container);
    String image = pod.getSpec().getContainers().get(0).getImage();
    String imageStreamTagName = KubernetesStringUtils.getTagNameFromPullSpec(image);
    ImageStreamTag imageStreamTag = getImageStreamTagFromRepo(imageStreamTagName);
    String sourcePullSpec = imageStreamTag.getTag().getFrom().getName();
    String trackingRepo = KubernetesStringUtils.stripTagFromPullSpec(sourcePullSpec);
    String tag = KubernetesStringUtils.getTagNameFromPullSpec(sourcePullSpec);
    tag(TagParams.create(trackingRepo, repo).withTag(tag));
    // Return value not used.
    return repo;
