Rebuild a custom hub image

We use a customized JupyterHub image so we can use versions of hub packages (such as authenticators) and install additional software required by custom config we might have.

The image is located in images/hub. It must inherit from the JupyterHub image used in the Zero to JupyterHub.

chartpress is used to build the image and update hub/values.yaml with the new image version. chartpress may be installed locally with pip install chartpress.

1. Run gcloud auth configure-docker us-central1-docker.pkg.dev once per machine to setup docker for authentication with the gcloud credential helper.

2. Modify the image in images/hub and make a git commit.

3. Run chartpress --push. This will build and push the hub image, and modify hub/values.yaml appropriately.

4. Make a commit with the hub/values.yaml file, so the new hub image name and tag are comitted.

5. Proceed to deployment as normal.

Some of the following commands may be required to configure your environment to run the above chartpress workflow successfully:

• gcloud auth login

• gcloud auth configure-docker us-central1-docker.pkg.dev

• gcloud auth application-default login

• sometimes running gcloud auth login additional time(s) may fix issues

• sudo usermod -a -G docker ${USER}

• gcloud auth configure-docker

Rebuild the custom postgres image

For data100, we provide a postgresql server per user. We want the python extension installed. So we inherit from the upstream postgresql docker image, and add the appropriate package.

This image is in images/postgres. If you update it, you need to rebuild and push it.

1. Modify the image in images/postgres and make a git commit.

2. Run chartpress --push. This will build and push the image, but not put anything in YAML. There is no place we can put thi in values.yaml, since this is only used for data100.

3. Notice the image name + tag from the chartpress --push command, and put it in the appropriate place (under extraContainers) in data100/config/common.yaml.

4. Make a commit with the new tag in data100/config/common.yaml.

5. Proceed to deploy as normal.
