Log based on registry known-poor support of HEAD in checking container
manifest.
Some private registries do not support HEAD (E.G. GitLab Container Registry).
With the current config, this log message is causing a notification to be
sent for each container hosted in a registry lacking HEAD support.
log.Debug or log.Warning for failed HTTP HEAD-check based on registry hostname
where HEAD-check is known to fail.
For Docker Hub, a failed HEAD leading to a "regular pull" may count against a
user's call-quota whereas other registry implementations do not support HEAD,
or whose container manifest may be in a different location.
* Revert "Image of running container no longer needed locally (#571)"
This reverts commit 6da66fb312.
* Update client.go
* fix: skip updating when no image info can be retrieved
This will allow watchtower to continue even though the image info for a
container cannot be retrieved. If this happens one warning will be emitted
and the container will be skipped, unless NoRestart or OnlyMonitor is supplied
* feat(update): add lifecycle hooks to the update action
* fix(ci): add bash tests for lifecycle-hooks to the ci workflow
* fix(ci): move integration tests to an isolated step
* fix(ci): fix malformed all-contributors json
* fix(ci): disable automatic bash test until we figure out a reasonable way to run it in circleci
