Demo Repository for IssueOps

Project demonstrating the power of issue based process handling using GitHub issues and actions.

Prerequisites

The repository has to meet several requirements that currently have to be set up manually:

• Issue Labels
• Environments
• GitHub App
• Variables
• Secrets

Issue Labels

The following issue labels have to be created:

• repo-request
• repo-deletion
• github-team-request

Environments

The following environments have to be set up:

deletion

The deletion environment is used to enforce a workflow review before repository deletion. Therefore, the environment has to be set up to require reviews (see docs to find out how this can be achieved).

github-team

The github-team environment is used to enforce a workflow review before team creation. Therefore, the environment has to be set up to require reviews (see docs to find out how this can be achieved).

GitHub App

A GitHub app with the following permissions is required:

• Read access to metadata
• Read and write access to administration, code, issues and members

It is possible to perform git operations using the apps identity. Retrieve the required username and email as follows:

# replace with your app name
APP_NAME=xpirit-training-bot

# create user name
USER=${APP_NAME}[bot]

# retrieve app ID from github
ID=$(curl -s -g https://api.github.com/users/$USER | jq '.id')

# display data
echo
echo CI_COMMIT_USER=$USER
echo CI_COMMIT_USER_MAIL=$ID+$USER@users.noreply.github.com

As an alternative, the user name and email can be fetched via browser as well. Open a browser and use the following url

https://api.github.com/users/{name-of-github-app}[bot]

where {name-of-github-app} is the name assigned to the app in the respective app settings. It is important that [bot] follows the name of the app.

The request returns a JSON that is displayed in the browser. From that request the value of the key "id" is required to assemble the user name and email address as following

User Name

{name-of-github-app}[bot]

User Email

{user-id}+{name-of-github-app}[bot]@users.noreply.github.com

where {user-id} is the value of the response key "id" and {name-of-github-app} is the name of the app. Remember to add [bot].

Secrets

The following secrets have to be configured:

Key	Description
GH_APP_KEY	Private key of the GitHub App

Variables

The following variables have to be configured:

Key	Description
GH_APP_ID	ID of the GitHub App
ORGANIZATION	GitHub organization
CI_COMMIT_USER	Name of the user for automated git tasks*
CI_COMMIT_USER_MAIL	Email of the user for automated git tasks*

*check GitHub App to see how to retrieve them

Issue Templates

Repository Management

Repository Request: repo-request.yml

Issue provising several inputs and dropdown selections to collect data required for repository creation via workflow.

The dropdown selections are automatically updated by the repo request update workflow.

Repository Deletion: repo-deletion.yml

Simple issue form taking the name of the repository as input which is supposed to be deleted via workflow.

GitHub Team Request: github-team-request.yml

Simple issue form taking the name and the description of the GitHub team as input which is supposed to be created via workflow.

Workflows

Issue Handling

Issues are handled in a three-tiered workflow.

1. Select the right workflow based on an issue label
2. Handle the issue and its data
3. Handle the corresponding task

    H --> K(GitHub Team created)
    style K fill:#d6d6d6,stroke:#000000,stroke-dasharray: 5 5

Loading

Handle Issue: handle-issue.yml

Workflow handling the issue templates. Depending on the given label the workflow executes the corresponding subworkflow.

The following subworkflows may be triggered:

• Repository request
• Repository deletion
• GitHub team request

Handle Repository Request: handle-repo-request.yml

Workflow parsing the repository request issue data and commenting / closing the issue depending on the workflow success.

The repository name is created with the following pattern:

[team name]-[repo name]

Example:

Repo: Romani Ite Domum
Team: Peoples Front

Full Repo Name: peoples-front-romani-ite-domum

The workflow further triggers the repository creation workflow.

Handle Repository Deletion: handle-repo-deletion.yml

Workflow parsing the repository deletion issue data and commenting / closing the issue depending on the workflow success.

The workflow further triggers the repository deletion workflow.

Handle GitHub Team Request: handle-github-team-request.yml

Workflow parsing the github team request issue data and commenting / closing the issue depending on the workflow success.

The workflow further triggers the github team request workflow.

Create Repository: repo-creation.yml

Workflow creating a repository from template data.

Delete Repository: repo-deletion.yml

Workflow deleting a repository by name.

Create GitHub Team: github-team-request.yml

Workflow creating a team from name and description on GitHub.

Organization Management

Update Repo Request Issue Template: update-repo-request-template.yml

Workflow to update dropdown selections in the Repo Request Issue Template.

The following selection data will be updated:

• Teams
• Languages

The workflow is triggered by any changes to the workflow file .github/workflows/update-repo-request-template.yml or the ./templates/languages directory and also runs each day at midnight to update eventual changes to the team structure.

The workflow reads the contents from the ./templates/languages folder expecting the following structure:

.
├── templates/
    └── languages/
        ├── language-1/
        │   ├── README.md
        │   └── language-files
        └── language-n/
            ├── README.md
            └── language-files

Any change to the structure will trigger the workflow and populate the issue template.
