This action sets up a Miniconda installation to use the Conda package and environment manager by either locating the Miniconda installation bundled with the available runners or by installing a specific Miniconda3 version. By default this action will also create a test environment.
Miniconda condabin/ folder is added to PATH and conda is correctly initialized across all platforms.
This action correctly handles activation of conda environments and offers the possibility of automatically activating the test environment on all shells.
See the IMPORTANT notes on additional information on environment activation.
For a full list of available inputs for this action see action.yml.
This example shows how to set a basic python workflow with conda using the crossplatform available shells: bash and pwsh. On this example an environment named test will be created with the specific python-version installed for each opearating system, resulting on 6 build workers.

conda listThis example shows how to use environment.yml for easier creation of test/build environments and .condarc files for fine grained configuration management. On this example we use a custom configuration file, install an environment from a yaml file and disable autoactivating the base environment before activating the anaconda-client-env.

- Bash shells do not use
~/.profileor~/.bashrcso these shells need to be explicitely declared asshell: bash -l {0}on steps that need to be properly activated. This is because bash shells are executed withbash --noprofile --norc -eo pipefail {0}thus ignoring updated on bash profile files made byconda init bash. See Github Actions Documentation and thread. - Sh shells do not use
