Files in Anyscale workspaces

Anyscale workspaces persist files and folders within your project directory across restarts. When you restart an Anyscale workspace, the files are injected using the working_dir option and are visible to your Ray application using the path /home/ray/default. This capability maintains project state between workspace sessions.

Anyscale workspaces use containers to launch clusters, meaning your files are isolated at the workspace level. See Container-driven development on Anyscale.

When you launch a job or service from an Anyscale workspace, Anyscale injects your files into the Ray cluster. See Local files, code, and directories in workspaces.

note

You shouldn't store large amounts of data in workspace files. For data exceeding the 10 GB limit, Anyscale recommends using object storage in your cloud provider account, such as S3 or GCS. See Storage.

When does Anyscale snapshot file changes?​

Whenever your Anyscale workspace restarts or terminates gracefully, Anyscale captures a snapshot of your current files during cluster termination. Workspaces that crash due to error might lose track of changes made since the last snapshot.

Snapshots only capture files under the path /home/ray/default, which is the default directory for your Anyscale workspace. If you install system packages or download files to locations higher in the directory structure for your workspace, Anyscale doesn't attempt to snapshot those files.

Anyscale attempts to take a periodic snapshot of your current files every five minutes. If the snapshot doesn't succeed after four minutes, Anyscale cancels the snapshot.

important

Anyscale limits snapshots to 10 GB per workspace. Periodic snapshots might begin to fail as you approach or exceed this threshold. Periodic snapshots that fail due to file size are likely to fail repeatedly, meaning that cluster termination can't persist changes to workspace files.

Anyscale sets a more forgiving timeout for workspace termination snapshots, but exceeding the size capacity for workspace files can also cause workspace termination snapshots to fail.

The following error message indicates you're experiencing size-based failures:

The workspace has failed to snapshot your files. Terminating the workspace might lead to loss of edits to workspace files. If you are currently storing data files in workspace files, this might lead to data loss. Large files or exceeding the 10 GB limit for workspace files can lead to snapshot failure. Identify large files and move them to the shared storage or object storage, or ignore them by adding them to .anyscaleignore. For more information about workspace file management and limitations, see the workspace files documentation. If problems persist, contact support@anyscale.com.

Exclude files from your working directory​

Anyscale uses the .gitignore and .anyscaleignore files to exclude files from the working directory.

The following default behaviors occur for all files specified in the ignore files:

  • Anyscale doesn't persist ignored files between workspace restarts.
  • Anyscale doesn't include ignored files when submitting jobs and services from a workspace.
  • Jobs and services also respect behaviors and settings for ignoring files when using the working_dir option for the CLI or SDK.

Exclude files with .gitignore​

The .gitignore file excludes files from Git tracking. Anyscale also ignores these files between workspace sessions and when submitting directories of files using the working_dir option.

To override this behavior and include files excluded by .gitignore in your Anyscale clusters, set the environment variable ­​ANYSCALE­­_DISABLE­­_GITIGNORE­­_EXCLUSION=1. This setting doesn't impact files ignored by the .anyscaleingore file.

note

An Anyscale workspace might include multiple Git repositories, each with their own .gitignore files. Anyscale applies override behavior across all directories in the workspace or working_dir.

Exclude files with .anyscaleignore​

The .anyscaleignore file excludes files and folders from persistence between workspace sessions and inclusion when using the working_dir option. Anyscale looks for this file in the top level of your workspace directory or the directory specified in the working_dir path. This location maps to /home/ray/default/.anyscaleignore in your Ray cluster.

The .anyscaleignore file supports the following patterns to match files and folders:

# .anyscaleignore example
*.txt                  # Ignore files with a .txt extension at the same level as `.anyscaleignore`.
**/*.txt               # Ignore files with a .txt extension in ANY directory.
folder/                # Ignore all files under "folder/". The slash at the end is optional.
folder/*.txt           # Ignore files with a .txt extension under "folder/".
path/to/filename.py    # Ignore a specific file by providing its relative path.
file_[1,2].txt         # Ignore file_1.txt and file_2.txt.
warning

The .anyscaleignore file supports a subset of patterns from .gitignore syntax and has some behavior difference. For example:

  • It doesn't support some patterns, such as negation and \ escaping.
  • Star matching (for example, *.txt) only matches files at the same level as .anyscaleignore. You must specify relative directories to exclude additional files.

See the Git docs on gitignore.
