This is the fork where work is being done on refactoring the HelperNode to use only containers. The following are the guiding principals:
-
Declarative approach to all services
-
The
vars.yaml(which will be renamed tohelpernode.yaml) will be the "source of truth" -
ALL services will be based on what is in this file.
-
Changes are to be made to the manifest file directly if a change is needed.
-
All services will be independet of each other
-
All services will be self contained
-
No dependecies between services where possible (exceptions only when absolutley needed)
-
The user can use all or just a subset of services
-
oc/openshift-install/helm utilites are stored in a container but can be pulled into the node
-
All logic for each containerized service will be in the
startup.shfile -
Client utility (
helpernodectl) should be used to interact with services/utilites -
No dependency to local storage
-
Containers should NOT rely on storage on the Host system (i.e. no mounting/binding like
-v /hostdir:/containerdir) -
Host using artifacts in containers is okay
-
helpernode.yamlis/should-be the only dependency on disk (besides the utility) -
Garbage in/Garbage out
-
Users should not have to deal with contianers directly
-
"HelperPod" should be versioned all the way through
-
it is also tied to the version of OpenShift
-
Ability to specify other OpenShift versions will be made availbe, but will NOT be supported by this project
-
i.e. if you fill out a github issue about this, it will be "closed/won’t fix"
"HelperPod" should be considered pre-alpha and every change should be considered a "breaking change" until the official 2.0 release.
You may be asking
Why do I see "HelperPod" everywhere.
It’s just a codename. Originally, the plan was to run the helpernode with podman play kube and that’s where the name comes from. This refactor is still evolving so stay tuned for more info.
