cmsdism 0.4.1

Command line interface to manage InferenceServices in KServe managed by DIALS.

dismcli

DIALS InfenceService Manager or simply dism is a program to deploy/remove InferenceServices in KServe managed by DIALS.

Local development

Install the dependencies and the package using uv:

uv sync --all-groups
uv pip install -e .
uv run pre-commit install

Tests

Run tests with pytest:

uv run pytest tests/ --cov=dismcli --cov-report=xml --cov-report=term

Tox

You may also want to run the tests with tox to test against multiple python versions:

uv run tox

asdf users

tox requires multiple versions of Python to be installed. Using asdf, you have multiple versions installed, but they aren’t normally exposed to the current shell. You can use the following command to expose multiple versions of Python in the current directory:

asdf set python 3.12.9 3.11.10 3.10.13

This will use 3.12.9 by default (if you just run python), but it will also put python3.11 and python3.10 symlinks in your PATH so you can run those too (which is exactly what tox is looking for).

GitLab CI Setup for dism-cli

This document describes the steps taken to configure GitLab CI for the dism-cli repository so it can access the private repository dism-core via SSH during pipeline execution.

Purpose

The dism-cli project depends on the dism-core repository using a Git+SSH link specified in pyproject.toml:

[tool.uv.sources]
dism-core = { git = "ssh://[e-mail]:7999/cms-dqmdc/libraries/dism-core.git", rev = "v1.0.0" }

To allow GitLab CI in dism-cli to clone dism-core, we need to set up SSH access.

Steps

1. Generate SSH Key Pair

Generate a new SSH key pair (without a passphrase) for CI access:

ssh-keygen -t ed25519 -f ci_key -N "" -C "dism-cli-ci-access"

• This creates:
  • ci_key (private key)
  • ci_key.pub (public key)

---

2. Add Deploy Key to dism-core

• Go to the dism-core project on GitLab.
• Navigate to: Settings > Repository > Deploy Keys
• Add a new key:
  • Title: dism-cli-ci-access
  • Key: paste the contents of ci_key.pub

---

3. Add CI/CD Variable to dism-cli

To securely provide the private key to GitLab CI:

1. Convert the private key to a base64 string:

   base64 -w0 ci_key > ci_key.b64
   

2. Copy the content of ci_key.b64.

3. Go to the dism-cli project on GitLab.

4. Navigate to: Settings > CI/CD > Variables

5. Add a new variable:

   • Key: CI_SSH_PRIVATE_KEY_B64
   • Value: paste the content from ci_key.b64
   • Type: Variable
   • Masked and Hidden: ✅

---

With this setup, the GitLab CI runner in dism-cli can authenticate with dism-core via SSH, allowing it to fetch dependencies during the test stage.
