*** 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):

the migration operation may take several hours if you have a lot of large images

of Docker will not complete successfully, and you will have the opportunity to

run a separate migration tool (which will not cause downtime for your Docker

daemon).
|
||||
|
||||
In order to run this migration tool, please install the 'docker-image-migrator'
|

package. You can run the migration with this command, which will exit after the
|

migration has been completed:
