Starting a service

Harbor

Ssh to the harbor instance (ex. toolsbeta-harbor-1.toolsbeta.eqiad1.wikimedia.cloud):

dcaro@vulcanus$ wm-ssh toolsbeta-harbor-1.toolsbeta.eqiad1.wikimedia.cloud 
...
dcaro@toolsbeta-harbor-1:~$ sudo -i
root@toolsbeta-harbor-1:~# cd /srv/ops/harbor/

root@toolsbeta-harbor-1:/srv/ops/harbor# docker-compose up -d  # will start the containers that are down if any
harbor-log is up-to-date
registry is up-to-date
redis is up-to-date
harbor-portal is up-to-date
registryctl is up-to-date
harbor-core is up-to-date
harbor-jobservice is up-to-date
nginx is up-to-date
harbor-exporter is up-to-date

Buildservice API

This lives in kubernetes, behind the API gateway. To start it you can try redepolying it, to do so follow Portal:Toolforge/Admin/Kubernetes#Deploy_new_version (the component is toolforge-builds-api).

You can monitor if it's coming up with the usual k8s commands:

root@toolsbeta-test-k8s-control-4:~# kubectl get all -n builds-api
NAME                              READY   STATUS    RESTARTS   AGE

Tekton

Similar to the builds api, tekton is a k8s component, you can try redepolying it too following Portal:Toolforge/Admin/Kubernetes/Components#Deploy (the component is buildservice).

You can monitor if it's coming up with the usual k8s commands:

root@toolsbeta-test-k8s-control-4:~# kubectl get all -n tekton-pipelines

Stopping a service

Harbor

Ssh to the harbor instance (ex. toolsbeta-harbor-1.toolsbeta.eqiad1.wikimedia.cloud):

dcaro@vulcanus$ wm-ssh toolsbeta-harbor-1.toolsbeta.eqiad1.wikimedia.cloud 
...
dcaro@toolsbeta-harbor-1:~$ sudo -i
root@toolsbeta-harbor-1:~# cd /srv/ops/harbor/

Stopping harbor-core       ... done
Stopping registry          ... done
Stopping harbor-portal     ... done
Stopping redis             ... done
Stopping registryctl       ... done
Stopping harbor-log        ... done

Buildservice API

Being a k8s deployment, the quickest way might be just to remove the deployment itself (will require redeploying to start again).

root@toolsbeta-test-k8s-control-4:~# kubectl get deployment -n builds-api builds-api -o yaml > backup.yaml  # in case you want to restore later with kubectl apply -f backup.yaml

root@toolsbeta-test-k8s-control-4:~# kubectl delete deployment -n builds-api builds-api

For a full removal (CAREFUL! Only if you know what you are doing) you can use helm:

root@toolsbeta-test-k8s-control-4:~# helm uninstall -n builds-api builds-api

Tekton

This one is a bit more tricky, but it would be removing the tekton controller itself (the one that handles the PipelineRun and TaskRun resources).

root@toolsbeta-test-k8s-control-4:~# kubectl get deployment -n tekton-pipelines tekton-pipelines-controller -o yaml > backup.yaml  # in case you want to restore later with kubectl apply -f backup.yaml

root@toolsbeta-test-k8s-control-4:~# kubectl delete deployment -n tekton-pipelines tekton-pipelines-controller

NOTE: Tekton does not have yet a helm deployment associated with it

Updating the builder image

You can find the latest info on the builds-builder git repo.

Adding a new buildpack

We keep a fork for the buildpacks we inject under https://gitlab.wikimedia.org/groups/repos/cloud/toolforge/buildpacks

Currently we are using the heroku builder and the heroku buildpacks, that usually are in the old heroku structure (as opposed to cloud-native). So we have to add a shim layer to make them cloud-native compatible.

You can see the latest examples in the repository, but a good start is to pull the buildpack from the cnb heroku url https://buildpack-registry.heroku.com/cnb/emk/rust where the last two parts of the path are the author and the name of the buildpack.

That will include a few scripts and files that are valid for cloud-native buildpack API 0.4, but we have to adapt them to API 0.6 at least as that's the minimum supported by the builder as of writting this.

For that, we have to:

Add a project.toml file
Change the api entry in the bulidpack.toml file
Change everywhere where a layer toml file is created to have the newer structure (see the existing examples).

You can create a new branch with the changes.

Once the fork is ready, we can add the buildpack to the list of buildpacks to inject in the builds-builder (see examples there).

Note that this might change soon for a nicer/easier flow, as we are just starting to discover how to manage these things.
