Please use the mamba-org/setup-micromamba action instead.
This action is deprecated and will no longer get maintained due to it being superseded by setup-micromamba
.
See mamba-org/setup-micromamba#70, mamba-org/provision-with-micromamba#103 and mamba-org/provision-with-micromamba#114 for reasons.
The most important difference for migrating is that in setup-micromamba
you need to specify the environment-file
argument while provision-with-micromamba
assumed environment.yml
by default.
extra-specs
is now called create-args
and should be used for all arguments that micromamba create
supports.

GitHub Action to provision a CI instance using micromamba.
provision-with-micromamba
requires the curl
and tar
programs (with bzip2
support).
They are preinstalled in the default GitHub Actions environments.
Required. Path to the environment.yml
or .lock
file for the Conda environment OR false
. If false
, only extra-specs will be considered and you should provide channels. If both environment-file and extra-specs are empty, no environment will be created (only micromamba
will be installed). See the Conda documentation for more information.
Default value: environment.yml
The name of the Conda environment. Defaults to name from the environment.yml
file set with environment-file. Required if environment-file is a .lock
file or false
, unless both environment-file and extra-specs are empty.
Version of micromamba to use, eg. "0.20"
. See https://github.com/mamba-org/mamba/releases/ for a list of releases.
Default value: latest
Additional specifications (packages) to install. Pretty useful when using matrix builds to pin versions of a test/run dependency. For multiple packages, use multiline syntax:
extra-specs: |
python=3.10
xtensor
Note that selectors
(e.g. sel(linux): my-linux-package
, sel(osx): my-osx-package
, sel(win): my-win-package
)
are available.
Comma separated list of channels to use in order of priority (eg., conda-forge,my-private-channel
)
Path to a .condarc
file to use. See the Conda documentation for more information.
Channel priority to use. One of "strict"
, "flexible"
, and "disabled"
. See https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-channels.html#strict-channel-priority for more information.
Default value: strict
If true
, cache downloaded packages across calls to the provision-with-micromamba action. Cache invalidation can be controlled using the cache-downloads-key option.
Custom download cache key used with cache-downloads: true
. The default download cache key will invalidate the cache once per day.
If true
, cache installed environments across calls to the provision-with-micromamba action. Cache invalidation can be controlled using the cache-env-key option.
Custom environment cache key used with cache-env: true
. With the default environment cache key, separate caches will be created for each operating system (eg., Linux) and platform (eg., x64) and day (eg., 2022-01-31), and the cache will be invalidated whenever the contents of environment-file or extra-specs change.
Micromamba log level to use. One of "trace"
, "debug"
, "info"
, "warning"
, "error"
, "critical"
, "off"
.
Default value: warning
Base URL to fetch Micromamba from. Files will be downloaded from <base url>/<platform>/<version>
, eg. https://micro.mamba.pm/api/micromamba/linux-64/latest.
Default value: https://micro.mamba.pm/api/micromamba
More options to append to .condarc
. Must be a string of valid YAML:
condarc-options: |
proxy_servers:
http: ...
Attempt to undo any modifications done to .bashrc
etc. in the post action of the workflow.
This is useful for self-hosted runners that keep the state of the system.
One of "auto"
, "true"
or "false"
.
If set to "auto"
, behaves like "true"
if the micromamba version used supports micromamba shell deinit
(i.e. micromamba>=0.25.0
).
Default value: auto

Use cache-downloads
to enable download caching across action runs (.tar.bz2
files).
By default the cache is invalidated once per day. See the cache-downloads-key
option for custom cache invalidation.
- name: Install Conda environment with Micromamba
uses: mamba-org/provision-with-micromamba@main
with:
cache-downloads: true
Use cache-env
to cache the entire Conda environment (envs/myenv
directory) across action runs.
By default the cache is invalidated whenever the contents of the environment-file
or extra-specs
change, plus once per day. See the cache-env-key
option for custom cache invalidation.
- name: Install Conda environment with Micromamba
uses: mamba-org/provision-with-micromamba@main
with:
cache-env: true
Due to a limitation of GitHub Actions any download or environment caches created on a branch will not be available on the main/parent branch after merging. This also applies to PRs.
In contrast, branches can use a cache created on the main/parent branch.

Some shells require special syntax (e.g. bash -l {0}
). You can set this up with the default
option:
jobs:
myjob:
defaults:
run:
shell: bash -l {0}
# Or top-level:
defaults:
run:
shell: bash -l {0}
jobs:
...
Find the reasons below (taken from setup-miniconda):
- Bash shells do not use
~/.profile
or~/.bashrc
so these shells need to be explicitly declared asshell: bash -l {0}
on steps that need to be properly activated (or use a default shell). 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. - Cmd shells do not run
Autorun
commands so these shells need to be explicitly declared asshell: cmd /C call {0}
on steps that need to be properly activated (or use a default shell). This is because cmd shells are executed with%ComSpec% /D /E:ON /V:OFF /S /C "CALL "{0}""
and the/D
flag disabled execution ofCommand Processor/Autorun
Windows registry keys, which is whatconda init cmd.exe
sets. See Github Actions Documentation. sh
is not supported. Please usebash
.
When developing, you need to
- install
nodejs
- clone the repo
- run
npm install -y
- run
npm run build
