argo --help

You can use the CLI in the following modes:

# Kubernetes API Mode (default)

Requests are sent directly to the Kubernetes API. No Argo Server is needed. Large workflows and the workflow archive are not supported.

Use when you have direct access to the Kubernetes API, and don't need large workflow or workflow archive support.

If you're using instance ID (which is very unlikely), you'll need to set it:


# Argo Server GRPC Mode

Requests are sent to the Argo Server API via GRPC (using HTTP/2). Large workflows and the workflow archive are supported. Network load-balancers that do not support HTTP/2 are not supported.

Use if you do not have access to the Kubernetes API (e.g. you're in another cluster), and you're running the Argo Server using a network load-balancer that support HTTP/2.

To enable, set ARGO_SERVER:

	ARGO_SERVER=localhost:2746 ;# The format is "host:port" - do not prefix with "http" or "https"

If you're have transport-layer security (TLS) enabled (i.e. you are running "argo server --secure" and therefore has HTTPS):


If your server is running with self-signed certificates. Do not use in production:


By default, the CLI uses your KUBECONFIG to determine default for ARGO_TOKEN and ARGO_NAMESPACE. You probably error with "no configuration has been provided". To prevent it:


You will then need to set:



	ARGO_TOKEN='Bearer ******' ;# Should always start with "Bearer " or "Basic ".

# Argo Server HTTP1 Mode

As per GRPC mode, but uses HTTP. Can be used with ALB that does not support HTTP/2. The command "argo logs --since-time=2020...." will not work (due to time-type).

Use this when your network load-balancer does not support HTTP/2.

Use the same configuration as GRPC mode, but also set:


If your server is behind an ingress with a path (you'll be running "argo server --basehref /...) or "BASE_HREF=/... argo server"):

      --argo-base-href string          An path to use with HTTP client (e.g. due to BASE_HREF). Defaults to the ARGO_BASE_HREF environment variable.

  -s, --argo-server host:port          API server host:port. e.g. localhost:2746. Defaults to the ARGO_SERVER environment variable.
      --as string                      Username to impersonate for the operation
      --as-group stringArray           Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
      --certificate-authority string   Path to a cert file for the certificate authority

      --cluster string                 The name of the kubeconfig cluster to use
      --context string                 The name of the kubeconfig context to use
      --gloglevel int                  Set the glog logging level
  -h, --help                           help for argo
      --insecure-skip-tls-verify       If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
  -k, --insecure-skip-verify           If true, the Argo Server's certificate will not be checked for validity. This will make your HTTPS connections insecure. Defaults to the ARGO_INSECURE_SKIP_VERIFY environment variable.
      --instanceid string              submit with a specific controller's instance id label. Default to the ARGO_INSTANCEID environment variable.

      --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")
  -e, --secure                         Whether or not the server is using TLS with the Argo Server. Defaults to the ARGO_SECURE environment variable. (default true)
