Creating a Custom Script

Scenarios

Create a custom script on Cloud Operations Center.

Precautions

Confirm and complete the risk level of the script content.

Procedure

1. Log in to COC.
2. In the navigation pane on the left, choose Resource O&M > Automated O&M. In the Routine O&M area, click Scripts. On the displayed Scripts page, click the Custom Scripts tab and click Create Script.

3. Enter the basic script information.

4. Enter the script content. The script type can be Shell, Python, or Bat. And verify high-risk commands in the script.
   

   The interpreter that is automatically added to the first line of the script content, for example, #!/usr/bin/python, requires a Python soft link on your VMs. If the soft link is missing, you need to modify the interpreter to ensure that it can be executed by your VMs.

5. Click Verify High-Risk Command.
   • Verification scope: the high-risk commands involved in the detection. You can click High-Risk Commands to view the verification rules.
   • Verification rule: Within the verification scope, the script content is matched with high-risk commands using regular expression matching.
   • Verification result: The regular expression is used to check whether the script content is high-risk, that is, low-risk or high-risk.
     

     The result of high-risk command verification is used only as a reference for grading the script risk level. The system does not forcibly require the consistency between script risk level and the verification result. Evaluate the risk level based on the actual service impact.
