O'Reilly bought and shut down katacoda.com 😕
Alternatives:
| Site | Notes |
|---|---|
| killercoda.com | Seems to be the closest replacement for Katacoda |
| Play with Docker | Just for Docker, requires a free Docker account |
| Instruqt | This looks like more of a solution for vendors than a generally available platform This is what Red Hat has chosen to replace Katacoda for their interactive tutorials: https://developers.redhat.com/learn#assembly-id-70181 Source code here: https://github.com/openshift-instruqt/instruqt |
