Rebuilding a first and second image based on software components having earlier versions for one or more appliances and performing a first and second integration test for each respective image in a runtime environment

A method far updating a virtual appliance, comprising:

• generating a workflow to update one or more appliances at an update server in response to a repository metadata server detecting an upstream update;
• identifying one or more software components associated with the upstream update to the one or more origin repositories;
• identifying at least one appliance having earlier versions of the identified software components installed therein;
• invoking a build engine to rebuild an image corresponding to the identified appliance to obtain a first rebuilt image, wherein the first rebuilt image includes the identified software components associated with the upstream update;
• invoking a runtime environment to manage, after the first rebuilt image is installed, a first integration test for the first rebuilt image corresponding to the identified appliance, wherein the at least one change is implemented to accommodate the upstream update in response to the first integration test failing, wherein the first integration test fails when the identified appliance does not function correctly after the first rebuilt image is installed on the identified appliance;
• invoking the build engine to rebuild a second image corresponding to the identified appliance to obtain a second rebuilt image when the first integration test fails, wherein the second rebuilt image includes a change implemented in response to the first integration test failing, wherein the change is provided by the user via the workflow;
• invoking the runtime environment to manage a second integration test for the second rebuilt image;
• and
• storing the second rebuilt image in an appliance repository, wherein the second rebuilt image is stored in the appliance repository in response to the second integration test verifying that the second rebuilt image functions correctly with the identified software components associated with the upstream update installed therein.
