Questions about Instruqt?
While the sandbox hosts are starting up, the Instruqt platform tries to make an SSH connection. You will see this in the logs:
Retrying SSH connection until it is available: ssh: handshake failed
This is expected behavior and it should not last more than 10-20 seconds until a connection is made.
Container images built using podman or buildah might not work properly. Sometimes tracks using those images won't start, and
instruqt track logsshows a message like this one:
2020-12-04T12:50:31Z bii3rgpaqgcr INFO: module.hostname.kubernetes_deployment.deployment: Still creating... [1m0s elapsed]
To resolve this issue, use the option
--format=dockerto push to the registry. The underlying problem is that the mediaType in the container image is not set properly, causing the Kubernetes pod to fail with the following error:
Error response from deamon: mediaType in manifest should be 'application/vnd.docker.distribution.manifest.v2+json' not ''
