Channels are the path that conda takes to look for packages, and the easiest way to use and manage custom channels is to use a private or public repository on Anaconda.org, formerly known as Binstar.org. If you designate your Anaconda.org repository as private, then only you, and those you grant access, can access your private repository.
If you do not wish to upload your packages to the internet, however, you can
build a custom repository served either through a web server, or locally
Custom channel/private repository summary¶
- Organize packages into platform subdirectories.
- Run conda index on each of the platform subdirectories.
- Test custom channels.
1. Organize packages into platform subdirectories¶
To create a custom channel, first organize all the packages in subdirectories for the platforms you wish to serve.
channel/ linux-64/ package-1.0-0.tar.bz2 linux-32/ package-1.0-0.tar.bz2 osx-64/ package-1.0-0.tar.bz2 win-64/ package-1.0-0.tar.bz2 win-32/ package-1.0-0.tar.bz2
2. Run conda index on each of the platform subdirectories¶
The ‘conda index’ command is part of the conda-build package. If you have not yet used conda build, begin by installing conda build:
conda install conda-build
Now run conda index on each of the platform subdirectories as shown:
conda index channel/linux-64 channel/osx-64
The conda index command generates a file
repodata.json, saved to each repository directory,
which conda uses to get the metadata for the packages in the channel.
Note: Each time you add or modify a package in the channel, you must re-run
conda index for
conda to see the update.
3. Test custom channels¶
You can now serve the custom channel using a web server, or using a
file:// url to the channel
directory. Test by sending a search command to the custom channel.
Example: if a file you want from the custom channel location is located at
Then search for files in that location as shown:
conda search -c file://opt/channel/ --override-channels
Note: The channel url does NOT include the platform, as conda will automatically detect and add the platform.
Note: the –override-channels is to be sure conda only searches your specified channel and no
other channels, such as default channels or any other channels you may have listed in your
If you have set up your private repository correctly, you will see:
Fetching package metadata: . . . .
This will be followed by a list of the conda packages found. This verifies that you have set up and indexed your private repository successfully.
