  --upstream-channel UPSTREAM_CHANNEL
                        The target channel to mirror. Can be a channel on
                        anaconda.org like "conda-forge" or a full qualified

  --temp-directory TEMP_DIRECTORY
                        Temporary download location for the packages.
                        Defaults to a randomly selected temporary directory.
                        Note that you might need to specify a different

  -D, --include-depends

                        packages in whitelist.
  -v, --verbose         logging defaults to error/exception only. Takes up to

                        debug.
  --config CONFIG       Path to the yaml config file

  --dry-run             Show what will be downloaded and what will be
                        removed. Will not validate existing packages
  --no-validate-target  Skip validation of files already present in target-
                        directory
  --minimum-free-space MINIMUM_FREE_SPACE
                        Threshold for free diskspace. Given in megabytes.
  --proxy PROXY         Proxy URL to access internet if needed
  --ssl-verify SSL_VERIFY, --ssl_verify SSL_VERIFY
                        Path to a CA_BUNDLE file with certificates of trusted
                        CAs, this may be "False" to disable verification as
                        per the requests API.
  -k, --insecure        Allow conda to perform "insecure" SSL connections and
                        transfers. Equivalent to setting 'ssl_verify' to
                        'false'.
  --max-retries MAX_RETRIES
                        Maximum number of retries before a download error is
                        reraised, defaults to 100
  --no-progress         Do not display progress bars.

Example Usage

WARNING: Invoking this command will pull ~10GB and take at least an hour

conda-mirror --upstream-channel conda-forge --target-directory local_mirror --platform linux-64

More Details

blacklist/whitelist configuration

example-conf.yaml:

blacklist:
  - license: "*agpl*"
  - license: None
  - license: ""

whitelist:
  - name: system

blacklist removes package(s) that match the condition(s) listed from the upstream repodata.

whitelist re-includes any package(s) from blacklist that match the whitelist conditions.

blacklist and whitelist both take lists of dictionaries. The keys in the dictionary need to be values in the repodata.json metadata. The values are (unix) globs to match on, but in the case of the version attribute, conda package match version specifications may also be used.

Go here for the full repodata of the upstream "defaults" channel: http://conda.anaconda.org/anaconda/linux-64/repodata.json

Here are the contents of one of the entries in repodata['packages']

{'botocore-1.4.10-py34_0.tar.bz2': {'arch': 'x86_64',
  'binstar': {'channel': 'main',
   'owner_id': '55fc8527d3234d09d4951c71',

See implementation details in the conda_mirror:match function for more information.

Common usage patterns

Mirror only one specific package

If you wanted to match exactly the botocore package listed above with your config, then you could use the following configuration to first blacklist all packages and then include just the botocore packages:

blacklist:
  - name: "*"
whitelist:
  - name: botocore
    version: 1.4.10
    build: py34_0

you can use standard conda package version specifiers to filter a range of versions:

blacklist:
  - name: "*"
whitelist:
  - name: botocore
    version: ">=1.4.10,<1.5"

Mirror everything but agpl licenses

blacklist:
  - license: "*agpl*"

Mirror only python 3 packages

blacklist:
  - name: "*"
whitelist:
  - build: "*py3*"

Mirror specified packages and their dependencies

This will include all instances of botocore with at least version 1.4.10 along with any packages that match its dependencies (and likewise for dependencies of those packages).

blacklist:
  - name: "*"
whitelist:
  - name: botocore
    version: ">=1.4.10"
include_depends: True

If this includes too many packages versions, you can add additional entries to the whitelist to limit what will be included.

Testing

Install test requirements

Note: Will install packages from pip

$ pip install -r test-requirements.txt
Requirement already satisfied: pytest in /home/edill/miniconda/lib/python3.5/site-packages (from -r test-requirements.txt (line 1))
Requirement already satisfied: coverage in /home/edill/miniconda/lib/python3.5/site-packages (from -r test-requirements.txt (line 2))

Requirement already satisfied: py>=1.4.29 in /home/edill/miniconda/lib/python3.5/site-packages (from pytest->-r test-requirements.txt (line 1))

Other

After a new contributor makes a pull-request that is approved, we will reach out and invite you to be a maintainer of the project.

Releasing

To release you need three things

Commit rights to conda-mirror
A github token
The version number that you want to use for the new tag

After you have all three of these things, run the release.sh script (on a unix machine) and pass it the tag that you want to use and your github token:

GITHUB_TOKEN=<github_token> ./release.sh <tag>
