# Command line interface (AER 2.27)

## cas-mirror

NOTE: The cas-mirror tool is a component of the Anaconda repository enterprise product and is not available for free.

The mirror tool is used to setup a package mirror of the Anaconda repository within your organization. The following `conda` command installs the mirror tool:

    conda install cas-mirror

Installing cas-mirror will make these commands available:

    cas-sync --help
    cas-server --help

The first command `cas-sync` is used to bring the local mirror of the Anaconda repository up-to-date with our remote servers. To configure the location of the mirror on your file system, check the output of:

    cas-sync --config

and, if necessary, create a configuration file (either `~/.cas-mirror` or system-wise `/etc/cas-mirror`) which contains the desired location of the local mirror on the filesystem, the platforms which should be mirrored, as well as an optional blacklist of packages (the names of packages which should not be mirrored, e.g.

    mirror_dir: /home/data/mirror
    remote_url: ""  # where to get miniconda and anaconda installers -- blank to skip
    # possible platforms are: linux-64, linux-32, osx-64, win-32, win-64
    platforms:
      - linux-64
      - win-32
    blacklist:
      - dnspython
      - shapely
      - gdal

Once you are happy with the mirror directory (which may be the default), you can run:

    cas-sync

Running this command for the first time will take many hours, because the entire Anaconda repository is being downloaded. Subsequent runs will take significantly less time. To serve the Anaconda repository over HTTP, you can run:

    cas-server

The port on which the repository is being served may be changed using the `--port` option. Note that you will need to run `cas-server` as root when you intend to serve on port 80.

More extensive information about the cas-mirror tool’s functionality and configurable options is available here.

## cas-installer

A token from Continuum is required to install cas-installer, and you should have received it when your organization purchased Anaconda Repository, Workgroup or Enterprise. If you no longer have access to your token, submit a support ticket or contact us at priority support. You can also email support at the email address given to you by your sales representative.

When you have the token, run:

    export TOKEN=<your Anaconda Cloud token>
    conda config --add channels https://conda.anaconda.org/t/$TOKEN/anaconda-server

This tool allows you to create an installer for a conda environment. It is important that the cas-installer package is installed into the “root” conda environment (not “root” user). The following command ensures that this happens:

    conda install -n root cas-installer=1.3.2

Once installed, the `cas-installer` command will be available:

    cas-installer -h

The command takes an installer specification file as its argument, which specifies the name of the installer, the conda channel to pull packages from, the conda packages included in the installer etc. Here is an example:

    # ----------------- required -----------------
    # name
    name: test

    # channels to pull packages from
    # The &channels creates a backreference so that it can be reused as
    # *channels in the conda_default_channels section below.
    channels: &channels
      - http://repo.continuum.io/pkgs/free/

    # specifications
    specs:
      - python
      - grin

    # ----------------- optional -----------------
    # platform e.g. linux-32, osx-64, win-32 defaults to current platform
    #platform: linux-64

    # The conda default channels which are used when running a conda which
    # was installed be the cas-installer created (requires conda (3.6.2 or
    # greater) in the specifications). The *channels is a YAML reference to
    # &channels above.  It inserts all the channels from the channels key, so
    # that they do not have to be typed twice.
    conda_default_channels: *channels

    # installer filename
    #installer_filename: grin.sh

    # default install prefix
    default_prefix: /opt/anaconda

For Windows, the tool creates nsis-based `.exe` installers, which can only be created on a Windows platform, although the architecture may be different. For Unix, the tool creates bash-based `.sh` installer, which can only be created on Unix (Linux, Mac OS X) systems.
