# Installing KUD addons with emcoctl

1. Customize values.yaml as needed

To create a customized profile for a specific addon, edit the profile
as needed, and then (for example, cpu-manager):

```
    tar -czf /opt/kud/multi-cluster/addons/cpu-manager.tar.gz -C /opt/kud/multi-cluster/addons/cpu-manager/helm .
    tar -czf /opt/kud/multi-cluster/addons/cpu-manager_profile.tar.gz -C /opt/kud/multi-cluster/addons/cpu-manager/profile .
```

2. Create prerequisites to deploy addons

Apply prerequisites.  This step is optional.  If there are existing
resources in the cluster, it is sufficient to customize values.yaml
with the values of those resources.  The supplied YAML files creates
the controllers, one or more clusters, one project, and one logical
cloud.

    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh apply -f 00-controllers.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh apply -f 01-cluster.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh apply -f 02-project.yaml -v values.yaml\`

3. Deploy addons

This deploys the addons listed in the \`Addons\` and
\`AddonResources\` values in values.yaml.

    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh apply -f 03-addons-app.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh apply -f 04-addon-resources-app.yaml -v values.yaml\`

# Uninstalling KUD addons with emcoctl

1. Delete addons

    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh delete -f 04-addon-resources-app.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh delete -f 03-addons-app.yaml -v values.yaml\`

2. Cleanup prerequisites

    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh delete -f 02-project.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh delete -f 01-cluster.yaml -v values.yaml\`
    \`$ /opt/kud/multi-cluster/${CLUSTER_NAME}/artifacts/emcoctl.sh delete -f 00-controllers.yaml -v values.yaml\`

#### NOTE: Known issue: deletion of the resources fails sometimes as
some resources can't be deleted before others are deleted. This can
happen due to timing issue. In that case try deleting again and the
deletion should succeed.
