Container recovery

1. A method comprising:

initiating, by one or more processors, a run of a target container in a distributed computing environment;

detecting, by the one or more processors, at least one error occurring during the initiation of the target container;

determining, by the one or more processors, at least one fix image based, at least in part, on the at least one error;

initiating, by the one or more processors, a fix container based on the fix image, wherein the fix container creates a child container to the target container in a container hierarchy; and

in response to a determination that the fix container corrects the at least one error occurring during the initiation of the target container, updating, by the one or more processors, at least part of the target container using the fix container; and

running, by the one or more processors, in response to successfully performing the error recovery of the target container, the target container in the distributed computing environment.
