binderhub.build
Contains build of a docker image from a git repository.
Build
binderhub.build.
Represents a build of a git repository into a docker image.
This ultimately maps to a single pod on a kubernetes cluster. Many different build objects can point to this single pod and perform operations on the pod. The code in this class needs to be careful and take this into account.
For example, operations a Build object tries might not succeed because another Build object pointing to the same pod might have done something else. This should be handled gracefully, and the build object should reflect the state of the pod as quickly as possible.
name
(repo_url, ref)
cleanup
Delete a kubernetes pod.
cleanup_builds
Delete stopped build pods and build pods that have aged out
get_affinity
Determine the affinity term for the build pod.
There are a two affinity strategies, which one is used depends on how the BinderHub is configured.
In the default setup the affinity of each build pod is an “anti-affinity” which causes the pods to prefer to schedule on separate nodes.
In a setup with docker-in-docker enabled pods for a particular repository prefer to schedule on the same node in order to reuse the docker layer cache of previous builds.
get_cmd
Get the cmd to run to build the image
progress
Put the current action item into the queue for execution.
stop
Stop watching a build
stream_logs
Stream a pod’s logs
submit
Submit a build pod to create the image for the repository.
