pyviyatools Install Intructions

The pyviyatools are a set of command-line tools that call the SAS Viya REST API's from python. The tools can be used to make direct calls to any rest-endpoint (like a CURL command) or to build additional tools that make multiple rest calls to provide more complex functionality.

INSTALL

The tools are a package of files and should be downloaded as such. The individual files are not useable without the package.

The tools should be installed on the same machine that hosts the Viya command-line interfaces(CLI). The following command will install a copy of the tools in a sub-directory(pyviyatools) of the current directory.

git clone https://github.com/sassoftware/pyviyatools.git

Authenticate

The pyviya tools use the sas-admin auth CLI to authenticate to Viya. To use the tool you must create a profile and authenticate. This process is documented in the SAS Viya Administration guide here.

http://documentation.sas.com/?cdcId=calcdc&cdcVersion=3.3&docsetId=calcli&docsetTarget=n1e2dehluji7jon1gk69yggc6i28.htm&locale=en

If your environment is enabled for Transport Layer Security (TLS), you must set the SSL_CERT_FILE environment variable to the path location of the trustedcerts.pem file (if using the SAS default truststore) or the path location of your site-signed certificate (if using an internal truststore).

In addition you may need to set REQUESTS_CA_BUNDLE to the certificate location so that the requests library can find the certificates.

The tool will automatically use the default profile.

  1. To create a profile as a SAS Administrator logon to the machine that contains the Viya CLI's
  2. Run /opt/sas/viya/home/bin/sas-admin profile init and when prompter enter the base endpoint of your Viya server for example: http://myviyaserver.blah.com. You may enter your personal preference at the other prompts.
  3. After you create the profile there are two options to authenticate
  • Run /opt/sas/viya/home/bin/sas-admin auth login to authenticate to Viya enter the userid and password of the SAS Administrator when prompted.
  • Create an .authinfo file in your home directory with your userid and password and use loginviauthinfo.py to authenticate with the credentials in the file (you can use different authinfo files with the -f option)

The CLI allows for multiple profiles. To use a profile other than the default profile, for example newprofile

  1. Create a named profile sas-admin --profile newprofile profile init
  2. Logon with the named profile sas-admin --profile newprofile auth login
  3. Set the SAS_CLI_PROFILE environment variable to the name of the profile
  • LINUX: export SAS_CLI_PROFILE=newprofile
  • WINDOWS: set SAS_CLI_PROFILE=newprofile
  1. To revert to using the default variable reset the environment variable
  • LINUX: unset SAS_CLI_PROFILE
  • WINDOWS: set SAS_CLI_PROFILE=

The tools are self-documenting, for help on any tool call the tool passing -h or --help.

TEST

  1. Execute a test call. Change directory to your install directory and run:

    callrestapi.py -e /folders/folders -m get

The call should return the JSON for the folders in the viya deployment. Be patient it might take a few seconds the first time.

  1. To see the current setup, including python and package versions, environment variable settings, profile information and current user. Run

    showsetup.py
