Oracle Cloud remote batch creation of virtual machines

Objective

Due to the company's business needs, we need to create virtual machines in bulk to perform tasks that need to be destroyed after the task is run to conserve resources.
The way we create virtual in bulk is through the bash interface provided by Oracle Cloud, so our first step is to create a bash environment

One. Configure command line Interface on the Linux machine. 1. Python version number is greater than or equal to 2.7

[email protected] ~]$ python--version

2. Install the user with sudo permission

[Email protected] ~]# Visudo

Meet the criteria

2. Download and install the CLI

[Email protected] ~]$ curl-l "https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh" | Bash

View

3. Auto-Generate config CLI configuration file

This configuration file is used for authentication

Get user ocid:

Get tenant Ocid

4. Update the user key

To view the location of the key placement:

View Key Contents

Add encryption Key

4. Test whether the configuration is successful

Two. Batch deployment of node-machine scripts

Attention:

• Script uses
  • Create a node machine:./nodes_ocvh.sh Create 3
  • Delete node:./nodes_ocvh.sh Delete 2
