The default baseimage-docker installs `syslog-ng`, `cron` and `sshd` services during the build process. The default baseimage-docker installs `syslog-ng`, `cron` and `sshd` services during the build process.
In case you don't need one or more of these services in your image, you can disable its installation. In case you don't need one or more of these services in your image, you can disable its installation through the `image/buildconfig` that is sourced within `image/system_services.sh`. Do this at build time by passing a variable in with `--build-arg` as in `docker build --build-arg DISABLE_SYSLOG=1 image/`, or you may set the variable in `image/Dockerfile` with an ENV setting above the RUN directive.
As shown in the following example, to prevent `sshd` from being installed into your image, set `1` to the `DISABLE_SSH` variable in the `./image/buildconfig` file. These represent build-time configuration, so setting them in the shell env at build-time [will not have any effect](https://github.com/phusion/baseimage-docker/issues/459#issuecomment-439177442). Setting them in child images' Dockerfiles will also not have any effect.)
You can also set them directly as shown in the following example, to prevent `sshd` from being installed into your image, set `1` to the `DISABLE_SSH` variable in the `./image/buildconfig` file.
