## Environment Variables
For easy reference, the following list of environment variables are supported
by the `docker` command line:
* `DOCKER_CERT_PATH` The location of your authentication keys.
* `DOCKER_DRIVER` The graph driver to use.
* `DOCKER_HOST` Daemon socket to connect to.
* `DOCKER_NOWARN_KERNEL_VERSION` Prevent warnings that your Linux kernel is unsuitable for Docker.
* `DOCKER_RAMDISK` If set this will disable 'pivot_root'.
* `DOCKER_TLS_VERIFY` When set Docker uses TLS and verifies the remote.
* `DOCKER_TMPDIR` Location for temporary Docker files.
Because Docker is developed using 'Go', you can also use any environment
variables used by the 'Go' runtime. In particular, you may find these useful:
* `HTTP_PROXY`
* `HTTPS_PROXY`
* `NO_PROXY`
These Go environment variables are case-insensitive. See the
[Go specification](http://golang.org/pkg/net/http/) for details on these
variables.
## Help
To list the help on any command just execute the command, followed by the `--help` option.
