Git repos are added to the Fleet manager using the
GitRepo custom resource type. The
GitRepo type is namespaced. By default, Rancher will create two Fleet workspaces: fleet-default and fleet-local.
Fleet-defaultwill contain all the downstream clusters that are already registered through Rancher.
Fleet-localwill contain the local cluster by default.
Users can create new workspaces and move clusters across workspaces. An example of a special case might be including the local cluster in the
GitRepo payload for config maps and secrets (no active deployments or payloads).
While it's possible to move clusters out of either workspace, we recommend that you keep the local cluster in
For a multi-cluster style, please ensure you use the correct repo that will map to the right target clusters.
Create GitRepo instance¶
Git repositories are register by creating a
GitRepo following the below YAML sample. Refer
to the inline comments as the means of each field
kind: GitRepo apiVersion: fleet.cattle.io/v1alpha1 metadata: # Any name can be used here name: my-repo # For single cluster use fleet-local, otherwise use the namespace of # your choosing namespace: fleet-local spec: # This can be a HTTPS or git URL. If you are using a git URL then # clientSecretName will probably need to be set to supply a credential. # repo is the only required parameter for a repo to be monitored. # repo: https://github.com/rancher/fleet-examples # Enforce all resources go to this target namespace. If a cluster scoped # resource is found the deployment will fail. # # targetNamespace: app1 # Any branch can be watched, this field is optional. If not specified the # branch is assumed to be master # # branch: master # A specific commit or tag can also be watched. # # revision: v0.3.0 # For a private registry you must supply a clientSecretName. A default # secret can be set at the namespace level using the BundleRestriction # type. Secrets must be of the type "kubernetes.io/ssh-auth" or # "kubernetes.io/basic-auth". The secret is assumed to be in the # same namespace as the GitRepo # # clientSecretName: my-ssh-key # # If fleet.yaml contains a private Helm repo that requires authentication, # provide the credentials in a K8s secret and specify them here. Details are provided # in the fleet.yaml documentation. # # helmSecretName: my-helm-secret # # To add additional ca-bundle for self-signed certs, caBundle can be # filled with base64 encoded pem data. For example: # `cat /path/to/ca.pem | base64 -w 0` # # caBundle: my-ca-bundle # # Disable SSL verification for git repo # # insecureSkipTLSVerify: true # # A git repo can read multiple paths in a repo at once. # The below field is expected to be an array of paths and # supports path globbing (ex: some/*/path) # # Example: # paths: # - single-path # - multiple-paths/* paths: - simple # The service account that will be used to perform this deployment. # This is the name of the service account that exists in the # downstream cluster in the fleet-system namespace. It is assumed # this service account already exists so it should be create before # hand, most likely coming from another git repo registered with # the Fleet manager. # # serviceAccount: moreSecureAccountThanClusterAdmin # Target clusters to deploy to if running Fleet in a multi-cluster # style. Refer to the "Mapping to Downstream Clusters" docs for # more information. # # targets: ...
Adding private repository¶
Fleet supports both http and ssh auth key for private repository. To use this you have to create a secret in the same namespace.
For example, to generate a private ssh key
ssh-keygen -t rsa -b 4096 -m pem -C "[email protected]"
Note: The private key format has to be in
EC PRIVATE KEY,
RSA PRIVATE KEY or
PRIVATE KEY and should not contain a passphase.
Put your private key into secret:
kubectl create secret generic $name -n $namespace --from-file=ssh-privatekey=/file/to/private/key --type=kubernetes.io/ssh-auth
Private key with passphrase is not supported.
Fleet supports putting
known_hosts into ssh secret. Here is an example of how to add it:
Fetch the public key hash(take github as an example)
ssh-keyscan -H github.com
And add it into secret:
apiVersion: v1 kind: Secret metadata: name: ssh-key type: kubernetes.io/ssh-auth stringData: ssh-privatekey: <private-key> known_hosts: |- |1|YJr1VZoi6dM0oE+zkM0do3Z04TQ=|7MclCn1fLROZG+BgR4m1r8TLwWc= ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAq2A7hRGmdnm9tUDbO9IDSwBK6TbQa+PXYPCPy6rbTrTtw7PHkccKrpp0yVhp5HdEIcKr6pLlVDBfOLX9QUsyCOV0wzfjIJNlGEYsdlLJizHhbn2mUjvSAHQqZETYP81eFzLQNnPHt4EVVUh7VfDESU84KezmD5QlWpXLmvU31/yMf+Se8xhHTvKSCZIFImWwoG6mbUoWf9nzpIoaSjB+weqqUUmpaaasXVal72J+UX2B+2RPW3RcT0eOzQgqlJL3RKrTJvdsjE3JEAvGq3lGHSZXy28G3skua2SmVi/w4yCE6gbODqnTWlg7+wC604ydGXA8VJiS5ap43JXiUFFAaQ==
If you don't add it any server's public key will be trusted and added. (
ssh -o stricthostkeychecking=accept-new will be used)
If you are using openssh format for the private key and you are creating it in the UI, make sure a carriage return is appended in the end of the private key.
