README.md

ansible-role-anaconda

This role installes the Continuum Anaconda distribution with all its packages (aka Anaconda, ~500 MB installer, ~3 GB installed) or just the conda package manager and Python (aka Miniconda, ~40 MB installer, ~400 MB installed).

You choose your desired version of Python and Anaconda by choosing a propper installer-file. Installer-files follow a schema: (Ana|Mini)conda<Python-major-version>-<Distribution-version>-<Platform>.sh

Examples:
Miniconda3-4.3.21-Linux-x86_64.sh installs the conda package manager and Python-3.x from the distribution version 3.4.21 on 64-bit GNU/Linux.
Anaconda2-4.4.0-Linux-x86.sh installs the full distribution version 4.4.0 with Python-2.x on 32-bit GNU/Linux.

Online resource for Installer-files:

If you do not provide a installer file, you get a Miniconda installation with Python3 for x86_64 systems. See role defaults for details.

It is possible to install Miniconda and run conda install anaconda afterwards to get the full Ananconda distribution.

Be aware that this role sets the path to the Anaconda distribution at the beginning of $PATH in a global way for bash/ksh/zsh/ash (e.g. /etc/bash.bashrc.local) by default. Keep that in mind if your system depends on a specific python version. Set anaconda_set_path to False and handle $PATH by your own if you don't like this.

The installer-file will reside in anaconda_home_dir to detect version changes. Despite the fact, that you can up/downgrade your Anaconda distribution with the conda package manager, a full reinstall (uninstall first, new install afterwards) will be performed if the installer-file or anaconda_installer_uri change. As long as you don't change anaconda_installer_uri and the installer-file, your Anaconda installation will not be changed.

Requirements

This role should be almost OS-agnostic as long as you provide a suitable installer file and the target is a Unix-like system. The target hosts need access to anaconda_installer_uri resource. But this can be a local resource on the target host with file:///tmp/foo. So a full offline installation can be done in a short playbook.

Role Variables

parameter required default choices comments
anaconda_state no present present, absent Desired state of the Anaconda distribution. If absent, it tries to remove the Anaconda path from $PATH.
anaconda_home_dir no /opt/anaconda Path to Anaconda installation.
anaconda_installer_uri no see defaults URI to the installer file. Use https:// for remote or file:// for local files on the target host. The target host requires access to that file. See above for online resources.
anaconda_installer_md5 no see defaults The md5 checksum of the installer file. See above for online resources.
anaconda_installer_dir no anaconda_home_dir Destination folder for downloading the installer-file. If it's not anaconda_home_dir it will not be removed when state = absent.
anaconda_force_install no False boolean Run installer even if the installer-file is unchanged and Anaconda seems to be installed.
anaconda_set_path no True boolean Adds Anaconda's path to the beginning of $PATH for all bash/ksh/zsh/ash login shells. See above for details.
