Exclusion

Excluding registries, repositories, and images​

Eraser can exclude registries (example, docker.io/library/*) and also specific images with a tag (example, docker.io/library/ubuntu:18.04) or digest (example, sha256:80f31da1ac7b312ba29d65080fd...) from its removal process.

To exclude any images or registries from the removal, create configmap(s) with the label eraser.sh/exclude.list=true in the eraser-system namespace with a JSON file holding the excluded images.

$ cat > sample.json <<"EOF"
{
  "excluded": [
    "docker.io/library/*",
    "ghcr.io/eraser-dev/test:latest"
  ]
}
EOF

$ kubectl create configmap excluded --from-file=sample.json --namespace=eraser-system
$ kubectl label configmap excluded eraser.sh/exclude.list=true -n eraser-system

Exempting Nodes from the Eraser Pipeline​

Exempting nodes from cleanup was added in v1.0.0. When deploying Eraser, you can specify whether there is a list of nodes you would like to include or exclude from the cleanup process using the configmap. For more information, see the section on customization.
