| # hub-user-image-template :paperclip: | ||
| # stat20-user-image | ||
|
|
||
| This is a template repository for creating dedicated user images for UC Berkeley hubs. | ||
| This is the repository for the stat20 datahub and local user images. | ||
|
|
||
| ## Overall workflow :gear: | ||
|
|
||
| The overall workflow is to: | ||
|
|
||
| 1. Create a new repository using this one as a template. Be sure to set the owner as `berkeley-dsep-infra`. | ||
|
|
||
| 2. Fork that repository to create your image repository (optional, but recommended). | ||
|
|
||
| 3. Set the appropriate values in the Actions environment variables for `HUB` and `IMAGE`. | ||
|
|
||
| 4. Customize the image by editing repo2docker files in your image repository. | ||
|
|
||
| Changes can either be done by direct commits to main on your image repository, or through a pull request from a fork of your image repository. Direct commits will build the image and push it to Google Artifact Registry (GAR) on merge. PRs will also build the image and offer a link to test it using Binder (currently disabled). Merging the PR will also create and push a commit to the [datahub repo](https://github.com/berkeley-dsep-infra/datahub/), which requires a human to open a PR to merge said commit and deploy that image to the proper hub(s). | ||
|
|
||
| 5. Configure your Hub to use this new image | ||
|
|
||
| More detailed instructions are [located below](https://github.com/berkeley-dsep-infra/hub-user-image-template/#in-depth-guide). | ||
|
|
||
| ### Modifying the new image | ||
|
|
||
| Detailed instructions showing the workflow to modify an image and push it | ||
| the CI/CD workflow are located in the [contribution guide](CONTRIBUTING.md) | ||
|
|
||
| ### In-depth guide | ||
|
|
||
| Check out the 2i2c docs for an in-depth guide on how to use this template repository to create a custom user image and use it for your hub :arrow_right: https://infrastructure.2i2c.org/howto/update-env/#split-up-an-image-for-use-with-the-repo2docker-action. | ||
|
|
||
| Here's a rough guide on how to create your own fresh user image :arrow_right: https://docs.datahub.berkeley.edu/en/latest/admins/howto/new-image.html. | ||
|
|
||
| After creating a new image repo from here as a template, and bringing in the commit history (if any) of the image, you will need to set two [Github Actions Repository Variables](https://docs.github.com/en/actions/learn-github-actions/variables) for the image: `HUB` and `IMAGE`. | ||
|
|
||
| `HUB` is the short name of the hub (eg: `data100`, `datahub`, etc). | ||
| `IMAGE` is the path to the image in the Artifact Registry (eg: `ucb-datahub-2018/user-images/<hubname>-user-image`) | ||
|
|
||
| Next, you will need to give the newly created repo access to two organizational-level [secrets in the berkeley-dsep-infra repo](https://github.com/organizations/berkeley-dsep-infra/settings/secrets/actions): `GAR_SECRET_KEY` (to allow pushes to the Artifact Registry) and `DATAHUB_USER_IMAGE_BRANCH_PUSH` (to allow commits to be pushed to the [datahub](https://github.com/berkeley-dsep-infra/datahub) repo). | ||
|
|
||
| ## About this template repository :information_source: | ||
|
|
||
| This template repository enables [jupyterhub/repo2docker-action](https://github.com/jupyterhub/repo2docker-action). | ||
| This GitHub action builds a Docker image using the contents of this repo and pushes it to the [Google Artifact Registry](https://cloud.google.com/artifact-registry) registry. | ||
|
|
||
| ### The environment | ||
|
|
||
| It provides an example of a `environment.yml` conda configuration file for repo2docker to use. | ||
| This file can be used to list all the conda packages that need to be installed by `repo2docker` in your environment. | ||
| The `repo2docker-action` will update the [base repo2docker](https://github.com/jupyterhub/repo2docker/blob/HEAD/repo2docker/buildpacks/conda/environment.yml) conda environment with the packages listed in this `environment.yml` file. | ||
|
|
||
| **Note:** | ||
| A complete list of possible configuration files that can be added to the repository and be used by repo2docker to build the Docker image, can be found in the [repo2docker docs](https://repo2docker.readthedocs.io/en/latest/config_files.html#configuration-files). | ||
|
|
||
| ### Making changes to a single user server image | ||
|
|
||
| Once you've created the new image repo from this template, please refer to [the contribution instructions](CONTRIBUTING.md) located in the repo for detailed instructions. | ||
|
|
||
| ### The GitHub Action workflows | ||
|
|
||
| This template repository provides some GitHub Action workflows that can build and push the image to Google Artifact Repository when configured, and test the image on Binder. | ||
|
|
||
|  | ||
|
|
||
| #### 1. Build and test container image :arrow_right: [test.yaml](https://github.com/berkeley-dsep-infra/hub-user-image-template/blob/main/.github/workflows/test.yaml) | ||
|
|
||
| This workflow is triggered when a Pull Request is opened against the default branch (`main`).. | ||
| During PR builds, the image is **only** built and **not** pushed, unless explicitly configured to do so. | ||
|
|
||
| #### 2. Test this PR on Binder Badge :arrow_right: [binder.yaml](https://github.com/berkeley-dsep-infra/hub-user-image-template/blob/main/.github/workflows/binder.yaml.disable) | ||
|
|
||
| *Temporarily disabled* | ||
|
|
||
| Since our images are typically large and take > 10m to build, this means that Binderhub builds will currently time out. | ||
|
|
||
| This workflow posts a comment inside a pull request, every time a pull request gets opened. The comment contains a "Test this PR on Binder" badge, which can be used to access the image defined by the PR in [mybinder.org](https://mybinder.org/). | ||
|
|
||
|  | ||
|
|
||
| #### 3. Build, test and push container image :arrow_right: [build-push-open-pr.yaml](https://github.com/berkeley-dsep-infra/hub-user-image-template/blob/main/.github/workflows/build-push-image-commit.yaml) | ||
|
|
||
| After a PR is merged to `main`, this workflow builds the image again, pushes to the Artifact Registry and will create a push to the [Datahub repo](https://github.com/berkeley-dsep-infra/datahub) to update the image tag for any hubs that use this image. The PR there will need to be created manually. | ||
| See this repository's CONTRIBUTING.md for instructions. That information will eventually be migrated to docs.datahub.berkeley.edu. |
