+## 1.12.4
|
|
|
+
|
|
|
+**IMPORTANT**: Docker 1.12 ships with an updated systemd unit file for rpm
|
|
|
+based installs (which includes RHEL, Fedora, CentOS, and Oracle Linux 7). When
|
|
|
+upgrading from an older version of docker, the upgrade process may not
|
|
|
+automatically install the updated version of the unit file, or fail to start
|
|
|
+the docker service if;
|
|
|
+
|
|
|
+- the systemd unit file (`/usr/lib/systemd/system/docker.service`) contains local changes, or
|
|
|
+- a systemd drop-in file is present, and contains `-H fd://` in the `ExecStart` directive
|
|
|
+
|
|
|
+Starting the docker service will produce an error:
|
|
|
+
|
|
|
+ Failed to start docker.service: Unit docker.socket failed to load: No such file or directory.
|
|
|
+
|
|
|
+or
|
|
|
+
|
|
|
+ no sockets found via socket activation: make sure the service was started by systemd.
|
|
|
+
|
|
|
+To resolve this:
|
|
|
+
|
|
|
+- Backup the current version of the unit file, and replace the file with the
|
|
|
+ [version that ships with docker 1.12](https://raw.githubusercontent.com/docker/docker/v1.12.0/contrib/init/systemd/docker.service.rpm)
|
|
|
+- Remove the `Requires=docker.socket` directive from the `/usr/lib/systemd/system/docker.service` file if present
|
|
|
+- Remove `-H fd://` from the `ExecStart` directive (both in the main unit file, and in any drop-in files present).
|
|
|
+
|
|
|
+After making those changes, run `sudo systemctl daemon-reload`, and `sudo
|
|
|
+systemctl restart docker` to reload changes and (re)start the docker daemon.
