ics-ans-role-conda
Ansible role to install conda on CentOS and Debian.
mamba is also installed by default.
This role includes as well:
- a
condamodule that can be used to manage conda packages. - a
conda_envmodule that can be used to manage conda environments.
Role Variables
The role can create conda environments if you pass a list of yaml environment files via
the conda_env_files variable.
You can use both local files and http/https url:
conda_env_files:
- "{{ playbook_dir }}/config/molecule_env.yml"
- https://gitlab.esss.lu.se/ics-infrastructure/conda-environments/raw/master/molecule_env.ymlNote that this is deprecated as it has some drawbacks:
- the update is only based on the file content (via a handler) and not the environment itself
- handler can't be used when using
include_role
Using the conda_env module is the recommended way.
conda module
The conda module allows to install, update or remove conda packages.
mamba is used by default. Set use_mamba: false to use conda instead.
