uvartage 0.4.1

Wrapper for uv with artifact storage in airgapped environments

uvartage

A wrapper around uv for usage with artifact storage in airgapped environments

The uvartage command starts a REPL (read-eval-print loop) using the Python cmd module where environment variables have been set for uv and uvx to use an artifact storage that requires authentication.

Please note: so far, only Artifactory is supported as such an artifact storage backend.

For convenience, the git command is also supported.

Own command implementations include:

• cd changes directories
• env prints the available environment variables
• list partially implements the functionality of the Unix ls command (ie. list files and/or directories)
• pwd prints the working directory path
• sh can be used to run arbitrary commands using the shell interpreter

The credentials for the user are asked at start time, and stored in environment variables for each repository.

The REPL features a simple history, and tab completion for a subset of the commands (currently, only list and sh, based on paths in the file system).

The loop can be left in different ways, depending on the operating system:

• Unix: Ctrl-D
• Windows: Ctrl-Z followed by the enter key
• as an anternative, you could enter EOF literally and press the enter key to exit. This method should always work.

Prerequisites

uv has to be installed, but otherwise, only standard library modules are used.

Usage

Built.in usage information

[osuser@workstation workdir]$ uvartage --help
usage: uvartage [-h] [--version] [-v ] [--backend {artifactory}] [--ca-file CA_FILE] [--user USER]
                [USER@]HOSTNAME ...

Wrapper for uv with artifact storage in airgapped environments

positional arguments:
  [USER@]HOSTNAME       the artifact storage hostname, or user and hostname combined by '@'.
  repositories          the package repositories (default first). If not at least one repository name
                        is provided, the value of the environment variable UVARTAGE_DEFAULT_REPOSITORY
                        will be used.

options:
  -h, --help            show this help message and exit
  --version             print version and exit
  -v , --verbose        show more messages
  --backend {artifactory}
                        the artifact storage backend type (default and currently the only supported
                        backend: artifactory)
  --ca-file CA_FILE     a CA cert bundle file to be provided via SSL_CERT_FILE.
  --user USER           username for the artifact storage backend if the hostname is not explicitly
                        specified as USER@HOSTNAME; default is 'osuser'.

[osuser@workstation workdir]$

Example REPL start

... with examiniation of the environment variables set for uv

[osuser@workstation workdir]$ uvartage [e-mail] defaultrepo extrarepo1 extrarepo2
| Neither the environment variable 'SSL_CERT_FILE' has been set, nor a CA file explicitly through --ca-file.
| You might encounter problems if using a non-standard (i.e. organization internal) certificate authority.
