Create a GitRepo Resource

Create GitRepo Instance

Git repositories are registered by creating a GitRepo resource in Kubernetes. Refer to the creating a deployment tutorial for examples.

Git Repository Contents has detail about the content of the Git repository.

The available fields of the GitRepo custom resource are documented in the GitRepo resource reference

Proper Namespace

Git repos are added to the SUSE® Rancher Prime Continuous Delivery manager using the GitRepo custom resource type. The GitRepo type is namespaced. By default, Rancher will create two SUSE® Rancher Prime Continuous Delivery workspaces: fleet-default and fleet-local.

Fleet-default will contain all the downstream clusters that are already registered through Rancher.
Fleet-local will contain the local cluster by default.

If you are using SUSE® Rancher Prime Continuous Delivery in a single cluster style, the namespace will always be fleet-local. Check here for more on the fleet-local namespace.

For a multi-cluster style, please ensure you use the correct repo that will map to the right target clusters.

Adding Private Git Repository

SUSE® Rancher Prime Continuous Delivery 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 "user@email.com"

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, use the namespace the GitRepo is in:

kubectl create secret generic ssh-key -n fleet-default --from-file=ssh-privatekey=/file/to/private/key  --type=kubernetes.io/ssh-auth

Private key with passphrase is not supported.

The key has to be in PEM format.

SUSE® Rancher Prime Continuous Delivery 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.

Using HTTP Auth

Create a secret containing username and password. You can replace the password with a personal access token if necessary. Also see HTTP secrets in Github.

kubectl create secret generic basic-auth-secret -n fleet-default --type=kubernetes.io/basic-auth --from-literal=username=$user --from-literal=password=$pat

Just like with SSH, reference the secret in your GitRepo resource via clientSecretName.

spec:
  repo: https://github.com/fleetrepoci/gitjob-private.git
  branch: main
  clientSecretName: basic-auth-secret

Using Private Helm Repositories

The credentials will be used unconditionally for all Helm repositories referenced by the gitrepo resource. Make sure you don’t leak credentials by mixing public and private repositories. Use different helm credentials for each path, or split them into different gitrepos, or use helmRepoURLRegex to limit the scope of credentials to certain servers.

For a private Helm repo, users can reference a secret with the following keys:

username and password for basic http auth if the Helm HTTP repo is behind basic auth.
cacerts for custom CA bundle if the Helm repo is using a custom CA.
ssh-privatekey for ssh private key if repo is using ssh protocol. Private key with passphase is not supported currently.

For example, to add a secret in kubectl, run

kubectl create secret -n $namespace generic helm --from-literal=username=foo --from-literal=password=bar --from-file=cacerts=/path/to/cacerts --from-file=ssh-privatekey=/path/to/privatekey.pem

After secret is created, specify the secret to gitRepo.spec.helmSecretName. Make sure secret is created under the same namespace with gitrepo.

Use different helm credentials for each path

gitRepo.spec.helmSecretName will be ignored if gitRepo.spec.helmSecretNameForPaths is provided

Create a file secrets-path.yaml that contains credentials for each path defined in a GitRepo. Credentials will not be used for paths that are not present in this file. The path is the actual path to the bundle (ie to a folder containing a fleet.yaml file) within the git repository, which might have more segments than the entry under paths:.

Example:

path-one: # path path-one must exist in the repository
  username: user
  password: pass
path-two:  # path path-one must exist in the repository
  username: user2
  password: pass2

Create the secret

kubectl create secret generic path-auth-secret -n fleet-default --from-file=secrets-path.yaml

In the previous example credentials for username user will be used for the path path-one and credentials for username user2 will be used for the path path-two.

caBundle and sshPrivateKey must be base64 encoded.

If you are using "rancher-backups" and want this secret to be included the backup, please add the label resources.cattle.io/backup: true to the secret. In that case, make sure to encrypt the backup to protect sensitive credentials.
