*** WARNING ***
|
|
|
|
The docker service has not been restarted.
|
|
|
|
In the migration from docker<1.10.0 to docker>=1.10.0, the Docker image format
|
|
has changed to be completely content-addressible. This results in several positive
|
|
improvements to image operations (better caching during builds mainly). However,
|
|
the migration operation may take several hours if you have a lot of large images
|
|
on a Docker host. In order to ensure that you have minimum downtime, the docker
|
|
service has not been restarted as it will trigger this migration. You may either
|
|
restart this service at a time of your choosing or manually run the separate
|
|
migration tool (which will not cause downtime for your Docker daemon).
|
|
|
|
You can run the migration with this command, which will exit after the migration
|
|
has been completed:
|
|
|
|
$ %{_libexecdir}/docker-image-migrator/do-image-migration-v1to2.sh
|
|
|
|
Because the migrator requires information about the storage driver used by Docker,
|
|
the migration script will source %{_sysconfdir}/sysconfig/docker and use \$DOCKER_OPTS as
|
|
arguments to the migrator. If this automated migration fails, it will be re-attempted
|
|
with every known storage driver. In addition, the script accepts arguments which
|
|
will simiarly be appended to the set of arguments (after \$DOCKER_OPTS) to the
|
|
migrator.
|
|
|
|
Restarting docker without running this separate migration tool, WILL CAUSE DOWNTIME,
|
|
BECAUSE DOCKER WILL RUN THE MIGRATION ON FIRST START AND YOU WILL BE UNABLE TO START
|
|
ANY CONTAINERS OR USE ANY DOCKER COMMANDS (EVEN CONTAINERS WITH RESTART POLICIES ACTIVE):
