Is EESSI accessible?

EESSI can be accessed via a native (CernVM-FS) installation, or via a container that includes CernVM-FS.

Before you look into these options, check if EESSI is already accessible on your system.

Run the following command:

ls /cvmfs/


This ls command may take a couple of seconds to finish, since CernVM-FS may need to download or update the metadata for that directory.

If you see output like shown below, you already have access to EESSI on your system. 🎉

For starting to use EESSI, continue reading about Setting up environment.

If you see an error message as shown below, EESSI is not yet accessible on your system.

ls: /cvmfs/ No such file or directory
No worries, you don't need to be a 🧙 to get access to EESSI.
