description: >-
These Tasks are Git tasks to work with repositories used by other tasks
in your Pipeline.
The git-clone Task will clone a repo from the provided url into the
output Workspace. By default the repo will be cloned into the root of
your Workspace. You can clone into a subdirectory by setting this Task's
subdirectory param. This Task also supports sparse checkouts. To perform
a sparse checkout, pass a list of comma separated directory patterns to
this Task's sparseCheckoutDirectories param.
workspaces:
- name: output
description: The git repo will be cloned onto the volume backing this Workspace.
- name: ssh-directory
optional: true
description: |
A .ssh directory with private key, known_hosts, config, etc. Copied to
the user's home before git commands are executed. Used to authenticate
with the git remote when performing the clone. Binding a Secret to this
Workspace is strongly recommended over other volume types.
- name: basic-auth
optional: true
description: |
A Workspace containing a .gitconfig and .git-credentials file. These
will be copied to the user's home before any git commands are run. Any
other files in this Workspace are ignored. It is strongly recommended
to use ssh-directory over basic-auth whenever possible and to bind a
Secret to this Workspace over other volume types.
- name: ssl-ca-directory
optional: true
description: |
A workspace containing CA certificates, this will be used by Git to
verify the peer with when fetching or pushing over HTTPS.

- name: sslVerify
description: Set the `http.sslVerify` global git config. Setting this to `false` is not advised unless you are sure that you trust your git remote.
type: string
default: "true"
- name: subdirectory
description: Subdirectory inside the `output` Workspace to clone the repo into.
type: string
default: ""
- name: sparseCheckoutDirectories
description: Define the directory patterns to match or exclude when performing a sparse checkout.
type: string
default: ""
- name: deleteExisting
description: Clean out the contents of the destination directory if it already exists before cloning.
type: string
default: "true"
- name: httpProxy
description: HTTP proxy server for non-SSL requests.
type: string
default: ""
- name: httpsProxy
description: HTTPS proxy server for SSL requests.
type: string
