Deployment on the new cluster¶
These are temporary instructions for configuring and deploying hubs on the new cluster. (Temporary as we get GitHub Actions set up to do this automatically).
The two hubs are available at https://hub.earthdatascience.org/ea-hub and https://hub.earthdatascience.org/nbgrader-hub
GCloud setup¶
We’ve created a new GKE cluster called jhub2
. To set up authentication
to the new cluster:
gcloud container clusters get-credentials jhub2
Now this cluster will be the default for all gcloud
, kubectl
,
and helm
commands that you run locally.
If your authentication still seems messed up, you can delete the hidden
.kube
directory in your home directory and re-run the get-credentials
command.
Hub configuration¶
The configuration files for the hubs are now in a directory called
hub-configs
(NOT in hub-charts
). There is one file per hub
rather than a subdirectory for each hub. The deployment script expects these
to be named ‘’hubname.yaml
.
Docker configuration¶
This has not changed. There is a subdirectory for each hub under
user-images
. Edit the dockerfile as needed and commit your changes.
Deployment¶
To build and push Docker images, and to deploy the hub, use the
deploy.py
script.
Note
Make sure you have committed any changes to the Dockerfiles, as the script looks at the last commit to determine the tag and whether re-building is required!
To build the image only:
$ python deploy.py --build <hubname>
To build and push to Dockerhub (push only works in concert with –build):
$ python deploy.py --build --push <hubname>
After successfully building and pushing:
$ python deploy.py --deploy <hubname>
