Examples with Check io.fabric8.karaf.checks.Check used on opensource projects

Example 1 with Check

use of io.fabric8.karaf.checks.Check in project che by eclipse.

the class OpenShiftConnector method tag.

/**
     * Creates an ImageStreamTag that tracks a given image.
     *
     * <p> Docker tags are used extensively in Che: all workspaces run on tagged images
     * tracking built stacks. For new workspaces, or when snapshots are not used, the
     * tracked image is e.g. {@code eclipse/ubuntu_jdk8}, whereas for snapshotted workspaces,
     * the tracked image is the snapshot (e.g. {@code machine_snapshot-<identifier>}.
     *
     * <p> Since OpenShift does not support the same tagging functionality as Docker,
     * tags are implemented as ImageStreamTags, where the {@code From} field is always
     * the original image, and the ImageStreamTag name is derived from both the source
     * image and the target image. This replicates functionality for Che in Docker,
     * while working differently under the hood. The ImageStream name is derived from
     * the image that is being tracked (e.g. {@code eclipse/ubuntu_jdk8}), while the tag
     * name is derived from the target image (e.g. {@code eclipse-che/che_workspace<identifier>}).
     *
     * @see DockerConnector#tag(TagParams)
