Functions

​
set_working_directory 

set_working_directory(directory: str) -> dict[str, str]
Sets the working directory; works with both absolute and relative paths. Args:
  • directory: the directory to set as the working directory
Returns:
  • a dictionary containing a directory key of the directory that was set

​
agit_clone 

agit_clone(repository: str, branch: Optional[str] = None, commit_sha: Optional[str] = None, include_submodules: bool = False, access_token: Optional[str] = None, credentials: Optional['Block'] = None, directories: Optional[list[str]] = None) -> dict[str, str]
Asynchronously clones a git repository into the current working directory. Args:
  • repository: the URL of the repository to clone
  • branch: the branch to clone; if not provided, the default branch will be used
  • commit_sha: the commit SHA to clone; if not provided, the default branch will be used
  • include_submodules: whether to include git submodules when cloning the repository
  • access_token: an access token to use for cloning the repository; if not provided the repository will be cloned using the default git credentials
  • credentials: a GitHubCredentials, GitLabCredentials, or BitBucketCredentials block can be used to specify the credentials to use for cloning the repository.
Returns:
  • a dictionary containing a directory key of the new directory that was created
Raises:
  • subprocess.CalledProcessError: if the git clone command fails for any reason

​
git_clone 

git_clone(repository: str, branch: Optional[str] = None, commit_sha: Optional[str] = None, include_submodules: bool = False, access_token: Optional[str] = None, credentials: Optional['Block'] = None, directories: Optional[list[str]] = None) -> dict[str, str]
Clones a git repository into the current working directory. Args:
  • repository: the URL of the repository to clone
  • branch: the branch to clone; if not provided, the default branch will be used
  • commit_sha: the commit SHA to clone; if not provided, the default branch will be used
  • include_submodules: whether to include git submodules when cloning the repository
  • access_token: an access token to use for cloning the repository; if not provided the repository will be cloned using the default git credentials
  • credentials: a GitHubCredentials, GitLabCredentials, or BitBucketCredentials block can be used to specify the credentials to use for cloning the repository.
  • directories: Specify directories you want to be included (uses git sparse-checkout)
Returns:
  • a dictionary containing a directory key of the new directory that was created
Raises:
  • subprocess.CalledProcessError: if the git clone command fails for any reason
Examples: Clone a public repository: 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/PrefectHQ/prefect.git
Clone a branch of a public repository: 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/PrefectHQ/prefect.git
        branch: my-branch
Clone a private repository using a GitHubCredentials block: 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/org/repo.git
        credentials: "{{ prefect.blocks.github-credentials.my-github-credentials-block }}"
Clone a private repository using an access token: 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/org/repo.git
        access_token: "{{ prefect.blocks.secret.github-access-token }}" # Requires creation of a Secret block
Note that you will need to create a Secret block to store the value of your git credentials. You can also store a username/password combo or token prefix (e.g. x-token-auth) in your secret block. Refer to your git providers documentation for the correct authentication schema. Clone a repository with submodules: 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/org/repo.git
        include_submodules: true
Clone a repository with an SSH key (note that the SSH key must be added to the worker before executing flows): 
pull:
    - prefect.deployments.steps.git_clone:
        repository: git@github.com:org/repo.git
Clone a repository using sparse-checkout (allows specific folders of the repository to be checked out) 
pull:
    - prefect.deployments.steps.git_clone:
        repository: https://github.com/org/repo.git
        directories: ["dir_1", "dir_2", "prefect"]

​
pull_from_remote_storage 

pull_from_remote_storage(url: str, **settings: Any) -> dict[str, Any]
Pulls code from a remote storage location into the current working directory. Works with protocols supported by fsspec. Args:
  • url: the URL of the remote storage location. Should be a valid fsspec URL. Some protocols may require an additional fsspec dependency to be installed. Refer to the fsspec docs for more details.
  • **settings: any additional settings to pass the fsspec filesystem class.
Returns:
  • a dictionary containing a directory key of the new directory that was created
Examples: Pull code from a remote storage location: 
pull:
    - prefect.deployments.steps.pull_from_remote_storage:
        url: s3://my-bucket/my-folder
Pull code from a remote storage location with additional settings: 
pull:
    - prefect.deployments.steps.pull_from_remote_storage:
        url: s3://my-bucket/my-folder
        key: {{ prefect.blocks.secret.my-aws-access-key }}}
        secret: {{ prefect.blocks.secret.my-aws-secret-key }}}

​
pull_with_block 

pull_with_block(block_document_name: str, block_type_slug: str) -> dict[str, Any]
Pulls code using a block. Args:
  • block_document_name: The name of the block document to use
