Overview

Hello everyone, This article is part of the CircleCI series, The knowledge in this series is built in sequence.

Workspaces are additive-only data storage, It provides you with the ability to share data between Jobs, By persisting data to a workspace. and attach it to other jobs. Workspace is an off-container store, with additive-only permissions. View more info at CircleCI Docs

  Build:  # Job Name
    docker:  # in this example will built our code in docker container, however you can use linux, macOS, etc..
      - image: cimg/python:3.11.3  # Spcecify The python image.
    steps:  # Job Steps
      - checkout  # checkout code from GitHub

• #1 Create directory to store data in.

• #2 print and store echo-output file in workspace directory.

• #3 Type down the persist command, with passing the root directory "the created directory," Also pass the echo-output file. So, This step will store echo-output file only from workspace directory.

• #4 attach workspace at another job.

  As mentioned above, Workspace is an off-container store, with additive-only permissions. it'll store data just for 15 days. Surf the CircleCI Docs for more info.

That's it, Hope this article inspired you and will appreciate your feedback.
Thank you.
