Alibaba Cloud Genomics Compute Service (AGS) CLI is a generic command-line interface (CLI) for genomic compute services of Alibaba Cloud. AGS CLI integrates the features of Argo and provides support for commands of other Alibaba Cloud service add-ons.

Download and install AGS CLI

By default, AGS CLI uses Alibaba Cloud AccessKey pairs to access other Alibaba Cloud services. AGS CLI uses Log Service to collect pod logs. To use Log Service in a cluster of Container Service for Kubernetes (ACK), you must enable Log Service when you create the ACK cluster.

Run the following command to download AGS CLI and make the downloaded file executable. 
wget http://ags-hub.oss-cn-hangzhou.aliyuncs.com/ags-linux && chmod +x ags-linux && mv ags-linux  /usr/local/bin/ags
Note

You can run the ags config init to enter the required information in AGS CLI. By default, after AGS CLI is initialized, the configuration files are stored in the ~/.ags/config directory. You can run the ags config show command to display the configuration. In the configuration, AccessKeySecret is encrypted.

If you want to use Log Service to collect logs, you must configure ags config. For security purposes, we recommend that you create a separate AccessKey pair for AGS CLI and grant the permissions to access Log Service.

If you use a managed Kubernetes cluster, use kubectl to connect to the cluster and run the following command on Cloud Shell to use AGS CLI. For more information, see Use kubectl to connect to an ACK cluster. 
wget http://ags-hub.oss-cn-hangzhou.aliyuncs.com/ags-linux && chmod +x ags-linux && mv ags-linux  /usr/local/bin/ags

Features of AGS CLI

  • Fully compatible with Argo commands.
  • Allows you to query pod logs in Log Service after pods are deleted.
  • Allows you to use kubectl commands to manage clusters.
  • Supports the install and uninstall commands. You can quickly install and uninstall tools that are required by AGS CLI.
  • Allows you to run the get workflow command to query the resource usage of a workflow.
  • Supports special characters such as underscores (_) in YAML templates.
  • Allows you to use the securityContext feature for security settings.
  • Synchronizes the pending and fails states between pods and workflows.
  • Allows you to enable automatic retry by using YAML files.
  • Allows you to retry a workflow from a failed step.
  • Supports the Elastic Container Instance (ECI) serverless Kubernetes architecture.

Flags:
     --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
     --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
     --context string                 The name of the kubeconfig context to use
 -h, --help                           help for ags
     --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 a kube config. Only required if out-of-cluster
 -n, --namespace string               If present, the namespace scope for this CLI request
     --password string                Password for basic authentication to the API server
     --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")
     --server string                  The address and port of the Kubernetes API server
     --token string                   Bearer token for authentication to the API server
     --user string                    The name of the kubeconfig user to use
     --username string                Username for basic authentication to the API server
