gitops zombies
0.0.9
This simple tool will help you find kubernetes resources which are not managed via GitOps (flux2).
gitops-zombies discovers all apis installed on a cluster and identify resources which are not part of a Kustomization or a HelmRelease. It also acknowledges the following facts:
Ignores resources which are owned by a parent resource (For example pods which are created by a deployment)
Ignores resources which are considered dynamic (metrics, leases, events, endpoints, ...)
Filter out resources which are created by the apiserver itself (like default rbacs)
Filters secrets which are managed by other parties including helm or ServiceAccount tokens
Checks if the referenced HelmRelease or Kustomization exists
Checks if resources are still part of the kustomization inventory
Supports cross cluster kustomizations
brew tap raffis/gitops-zombies brew install gitops-zombies
gitops-zombies
A more advanced call might include a filter like the following to exclude certain resources which are considered dynamic (besides the builtin exclusions):
gitops-zombies --context staging -l app.kubernetes.io/managed-by!=kops,app.kubernetes.io/name!=velero,io.cilium.k8s.policy.cluster!=default
Also you might want to exclude some specific resources based on their names. It can be achieved through YAML configuration:
---apiVersion: gitopszombies/v1kind: ConfigexcludeResources: - name: default apiVersion: v1 kind: ServiceAccount- name: velero-capi-backup-.* namespace: velero apiVersion: velero.io/v1 kind: Backup cluster: management
Finds all kubernetes resources from all installed apis on a kubernetes cluste and evaluates whether they are managed by a flux kustomization or a helmrelease. Usage: gitops-zombies [flags] Flags: --add_dir_header If true, adds the file directory to the header of the log messages --alsologtostderr log to standard error as well as files (no effect when -logtostderr=true) --as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. --as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups. --as-uid string UID to impersonate for the operation. --cache-dir string Default cache directory (default "~/.kube/cache") --certificate-authority string Path to a cert file for the certificate authority --client-certificate string Path to a client certificate file for TLS --client-key string Path to a client key file for TLS --cluster string The name of the kubeconfig cluster to use --config string Config file (default "~/.gitops-zombies.yaml") --context string The name of the kubeconfig context to use --disable-compression If true, opt-out of response compression for all requests to the server --exclude-cluster strings Exclude cluster from zombie detection (default none) --fail Exit with an exit code > 0 if zombies are detected -h, --help help for gitops-zombies -a, --include-all Includes resources which are considered dynamic resources --insecure-skip-tls-verify If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure --kubeconfig string Path to the kubeconfig file to use for CLI requests. --log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0) --log_dir string If non-empty, write log files in this directory (no effect when -logtostderr=true) --log_file string If non-empty, use this log file (no effect when -logtostderr=true) --log_file_max_size uint Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800) --logtostderr log to standard error instead of files (default true) -n, --namespace string If present, the namespace scope for this CLI request --no-stream Display discovered resources at the end instead of live --one_output If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true) -o, --output string Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file, custom-columns, custom-columns-file, wide). See custom columns [https://kubernetes.io/docs/reference/kubectl/overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [https://kubernetes.io/docs/reference/kubectl/jsonpath/]. --request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0") -l, --selector string Label selector (Is used for all apis) -s, --server string The address and port of the Kubernetes API server --skip_headers If true, avoid header prefixes in the log messages --skip_log_headers If true, avoid headers when opening log files (no effect when -logtostderr=true) --stderrthreshold severity logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=false) (default 2) --tls-server-name string Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used --token string Bearer token for authentication to the API server --user string The name of the kubeconfig user to use -v, --v Level number for the log level verbosity --version Print version and exit --vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
