This assumes:

• You have an ArgoCD server up and running. If not, check out my article Install Red Hat OpenShift GitOps Operator using the console (Argo CD)
• You have installed the ArgoCD CLI.
• You are able to log into ArgoCD using the CLI. If not, check out my article Log into ArgoCD using the CLI on OpenShift

The argocd repo list command can be used to list the repo's you have added to ArgoCD.

~]$ argocd repo list
TYPE  NAME                 REPO                                             INSECURE  OCI    LFS    CREDS  STATUS      MESSAGE  PROJECT
git   argocd-example-apps  https://github.com/argoproj/argocd-example-apps  false     false  false  false  Successful           default

Or on the Kubernetes or OpenShift cluster that ArgoCD is in the kubectl (Kubernetes) or oc (OpenShift) get secret command can be used to list the secrets in the namespace ArgoCD is in. There should be a secret for each repo that has been added to ArgoCD.

~]$ oc get secrets --namespace openshift-gitops
NAME                     TYPE            DATA   AGE

repo-321785470           Opaque          4      24d
repo-38486771            Opaque          6      55d

The kubectl (Kubernetes) or oc (OpenShift) get secret command with the --output jsonpath and base64 --decode command can be used to display the name of the repo in ArgoCd, the ArgoCD project that the repo is configured to use, the repo type, the repo URL, 

~]$ oc get secret repo-38486771 --namespace openshift-gitops --output jsonpath="{.data.name}" | base64 --decode
bar

~]$ oc get secret repo-38486771 --namespace openshift-gitops --output jsonpath="{.data.project}" | base64 --decode
default

 ~]$ oc get secret repo-38486771 --namespace openshift-gitops --output jsonpath="{.data.type}" | base64 --decode
git

~]$ oc get secret repo-38486771 --namespace openshift-gitops --output jsonpath="{.data.url}" | base64 --decode
https://github.com/foo/bar

Or on the Kubernetes or OpenShift cluster that ArgoCD is in the kubectl (Kubernetes) or oc (OpenShift) exec command can be used to run the argocd cluster list command in the ArgoCD server pod. It is noteworthy that by default the argocd login command will create the hidden .config file in the root directory of the operating system /.config and only root has permission to create files in the root directory of the operating system thus the --config /home/argocd/.config option is used so that the hidden .config file is create in our users home directory.

~]$ SERVER_POD=$(oc get pod --namespace openshift-gitops --selector=app.kubernetes.io/name=openshift-gitops-server --output custom-columns=POD:.metadata.name --no-headers)
~]$ ADMIN_PASSWD=$(oc get secret openshift-gitops-cluster --namespace openshift-gitops --output jsonpath='{.data.admin\.password}' | base64 --decode)
~]$ URL=$(oc get routes --namespace openshift-gitops --selector=app.kubernetes.io/name=openshift-gitops-server --output jsonpath="{.items[*].spec.host}")

~]$ oc exec $SERVER_POD --namespace openshift-gitops -- /bin/bash -c "argocd login --username admin --password $ADMIN_PASSWD $URL:443 --insecure --grpc-web --config /home/argocd/.config; argocd repo list --server $URL:443 --insecure --grpc-web --config /home/argocd/.config"
'admin:login' logged in successfully
TYPE  NAME                 REPO                                             INSECURE  OCI    LFS    CREDS  STATUS      MESSAGE  PROJECT
git   argocd-example-apps  https://github.com/argoproj/argocd-example-apps  false     false  false  false  Successful           default

Likewise the argocd repo get <repo url> command can be used to return a specific repo.

~]$ argocd repo get https://github.com/argoproj/argocd-example-apps
TYPE  NAME                 REPO                                             INSECURE  OCI    LFS    CREDS  STATUS      MESSAGE  PROJECT
git   argocd-example-apps  https://github.com/argoproj/argocd-example-apps  false     false  false  false  Successful           default

The --output json flag can be used to display output as JSON instead of YAML.

~]$ argocd repo get https://github.com/argoproj/argocd-example-apps --output json
{
  "repo": "https://github.com/argoproj/argocd-example-apps",
  "connectionState": {
    "status": "Successful",
    "message": "",
    "attemptedAt": "2024-12-19T02:43:04Z"
  },
  "type": "git",
  "name": "argocd-example-apps",
  "project": "default"
}

Likewise, the kubectl (Kubernetes) or oc (OpenShift) get secrets command can be used to list the secrets in the namespace ArgoCD is installed in, which is typically argocd or openshift-gitops and there should be a secret for each repository you have added to ArgoCd.

~]$ oc get secrets --namespace openshift-gitops | grep -i repo
repo-321785470                                                    Opaque                                4      7d14h
repo-3598070695                                                   Opaque                                6      23h
repo-38486771                                                     Opaque                                6      37d

The --output yaml or --output json option can be used to display the JSON or YAML for the secret.

~]$ oc get secret repo-3598070695 --namespace openshift-gitops --output yaml
apiVersion: v1
data:
  name: amVyZW1adsffYW5kYm94
  password: Z2hwX2dnRVZaa1MwTjADSFVDSDzBwTzNDcU5tQ1NtUzBvRk5lWA==

  type: Z2l0
  url: aHR0cHM6LyADFBADSFY29tL3Rocml2ZW50L2plcmVteXMtc2FuZGJveC5naXQ=
  username: Ia=
kind: Secret
metadata:
  annotations:
    managed-by: argocd.argoproj.io
  creationTimestamp: "2025-01-23T02:08:59Z"
  labels:
    argocd.argoproj.io/secret-type: repository
  name: repo-3598070695

  resourceVersion: "432844381"
  uid: 45a723c5-32ff-420e-b940-ba35074476c4
type: Opaque

And the jsonpath and base64 options can be used to return the cleartext values in the secret.

~]$ oc get secret repo-3598070695 --namespace openshift-gitops --output jsonpath="{.data.url}" | base64 --decode
https://github.com/foo/bar.git
