The Orchestra platform aims to facilitate data science education. The current iteration supports a flexible approach to making workshop or tutorial materials available to any user anywhere in the world via an Rstudio, Jupyter Notebook, or any other web-based data science framework (including LearnR shiny apps, for example).
A simple Choose a Workshop page presents all available environments for workshops. Choose one, enter your email, and within a minute or so, you get a dedicated compute environment with all necessary software installed and workshop materials available.
Use the BuildAWorkshop template repo or simply create a docker image that presents a web application (Rstudio, Jupyter Lab, Shiny App, etc) and send me an email.
We use these projects:
A snapshot of a running infrastructure:
helm install prometheus stable/prometheus
NAME: prometheus
LAST DEPLOYED: Tue Jul 28 20:02:17 2020
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
The Prometheus server can be accessed via port 80 on the following DNS name from within your cluster:
prometheus-server.default.svc.cluster.local
Get the Prometheus server URL by running these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=server" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace default port-forward $POD_NAME 9090
The Prometheus alertmanager can be accessed via port 80 on the following DNS name from within your cluster:
prometheus-alertmanager.default.svc.cluster.local
Get the Alertmanager URL by running these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=alertmanager" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace default port-forward $POD_NAME 9093
