### Create a service with configs
Use the `--config` flag to give a container access to a
[config](config_create.md).
Create a service with a config. The config will be mounted into `redis-config`,
be owned by the user who runs the command inside the container (often `root`),
and have file mode `0444` or world-readable. You can specify the `uid` and `gid`
as numerical IDs or names. When using names, the provided group/user names must
pre-exist in the container. The `mode` is specified as a 4-number sequence such
as `0755`.
```bash
$ docker service create --name=redis --config redis-conf redis:3.0.6
```
Create a service with a config and specify the target location and file mode:
```bash
$ docker service create --name redis \
--config source=redis-conf,target=/etc/redis/redis.conf,mode=0400 redis:3.0.6
```
To grant a service access to multiple configs, use multiple `--config` flags.
Configs are located in `/` in the container if no target is specified. If no
target is specified, the name of the config is used as the name of the file in
the container. If a target is specified, that is used as the filename.
