fasttrackml-ui-mlflow

Classic MLFlow UI built for FastTrackML

How is the repo working?

The main branch only contains Go code and CI workflows.

The release/vX.Y.Z branches fork from the main branch and add the MLFlow UI source code, imported automatically from the upstream repo. Further customization of the UI happens there.

The vX.Y.Z tags contain the built UI and the Go code only.

How to import a new upstream version?

Add/update the file upstream.txt in the main branch via pull request. Once merged, the CI will run and create a new release/vX.Y.Z branch for you with the imported source code.

How to customize the UI?

Start from the appropriate release/vX.Y.Z and make your changes. You can build the UI by going into the builder directory and running the following command:

go run main.go

An embed directory will be created with the built UI, ready to be embedded in the FastTrackML server via Go workspaces.

Once you're happy with them, create a pull request against the release/vX.Y.Z branch* that you started from (not main!). Once merged, the CI will run and build the UI. It will then push it to a new tag that is compatible with the Go module rules. For example, the first customization to v3.16.2 of Aim will end up in a tag named v0.31602.1.

How is this all enforced?

A GitHub app has been created with the contents:write permissions on this repo. Its App ID and private key are stored as secrets under the restricted environment. This environment is limited to the main and release/v* branches

Rulesets have been created to enforce that:

• main and release/v* branches require pull request reviews
• the GitHub app can create new release/v* branches
• the GitHub app can create new v* tags
• everything else (branch creation or deletion) is denied

Here is what they look like with the GitHub API at the time of writing:

The rules can be exported with the following scripts using gh:

for rule in $(gh api /repos/G-Research/fasttrackml-ui-mlflow/rulesets -q '.[].id')
do
  gh api /repos/G-Research/fasttrackml-ui-mlflow/rulesets/$rule | jq '[{name: .name, target: .target, conditions: .conditions, rules: .rules, bypass_actors: .bypass_actors}]'
done | jq -s add
