Gitops-Zombies
0.0.9
Dieses einfache Tool hilft Ihnen, Kubernetes-Ressourcen zu finden, die nicht über GitOps (flux2) verwaltet werden.
gitops-zombies erkennt alle auf einem Cluster installierten APIs und identifiziert Ressourcen, die nicht Teil einer Kustomization oder eines HelmRelease sind. Es erkennt außerdem die folgenden Tatsachen an:
Ignoriert Ressourcen, die einer übergeordneten Ressource gehören (z. B. Pods, die von einer Bereitstellung erstellt werden)
Ignoriert Ressourcen, die als dynamisch gelten (Metriken, Leases, Ereignisse, Endpunkte usw.)
Filtern Sie Ressourcen heraus, die vom Apiserver selbst erstellt werden (z. B. Standard-Rbacs).
Filtert Geheimnisse, die von anderen Parteien verwaltet werden, einschließlich Helm- oder ServiceAccount-Tokens
Überprüft, ob die referenzierte HelmRelease oder Kustomization vorhanden ist
Überprüft, ob Ressourcen noch Teil des Kustomisierungsinventars sind
Unterstützt Cluster-übergreifende Anpassungen
brew tap raffis/gitops-zombies brew install gitops-zombies
gitops-zombies
Ein erweiterter Aufruf könnte einen Filter wie den folgenden enthalten, um bestimmte Ressourcen auszuschließen, die als dynamisch gelten (neben den integrierten Ausschlüssen):
gitops-zombies --context staging -l app.kubernetes.io/managed-by!=kops,app.kubernetes.io/name!=velero,io.cilium.k8s.policy.cluster!=default
Möglicherweise möchten Sie auch bestimmte Ressourcen aufgrund ihrer Namen ausschließen. Dies kann durch die YAML-Konfiguration erreicht werden:
---apiVersion: gitopszombies/v1kind: ConfigexcludeResources: - Name: Standard APIVersion: v1 Art: ServiceAccount-Name: velero-capi-backup-.* Namensraum: velero API-Version: velero.io/v1 Art: 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
