Workflow and Volumes Example

In this example, we assume that no referenced volumes have been created. You can run this workflow under any account. When running this workflow the Fuzzball Storage Service will automatically create the referenced volume, the user home volume directory, and an ephemeral volume directory. The user home directory persists after the workflow ends and will appear in the Storage Volume listing, while the ephemeral volume is deleted when the workflow ends:

version: v1

volumes:
  myhome:
    reference: volume://user/homedir
  data:
    reference: volume://user/ephemeral
    ingress:
    - source:
        uri: https://raw.githubusercontent.com/ErikSchierboom/sentencegenerator/master/samples/the-king-james-bible.txt
      destination:
        uri: file://bible.txt

    command:
    - sh
    - -c
    - "cat /data/bible.txt | tr '[:lower:]' '[:upper:]' > $HOME/bible.txt"
    env:
    - HOME=/myhome
