4 years ago From the AWS Boto 3 documentation regarding describe_security_groups(**kwargs) the syntax seems different from the EC2 Helper Function code. Here's is the suggested syntax:
response = client.describe_security_groups( Filters=[ { 'Name': 'string', 'Values': [ 'string', ] }, ], GroupIds=[ 'string', ], GroupNames=[ 'string', ], DryRun=True|False, NextToken='string', MaxResults=123 )
I tried making modifications to the EC2:Helper Function script; however, it's not clear how hte GroupIDs should be set. Using the variable instance_security_group_id from the AWS VPC Create security group script, but this did not work.
Reference is: "https://aws.amazon.com/getting-started/tutorials/launch-a-virtual-machine/" The opening paragraph of this document suggests that Amazon Lightsail is easier to use; however, as this is an alternative to AWS EC2, I'll by-pass this for now. Maybe worth clarifying whether this is a useful alternative; perhaps for less experienced users.
Step 3 of the tutorial is "Configure your Instance". A question that arises is whether the configuration used in this tutorial is what's needed for running the cryptocurrency nodes. If not than one approach to the documentation could be to use this webpage as a template but modify it for our use. Scrolling through the files, there is a python script "AWS EC2" which appears to be the code necessary to configure an instance; however, the documentation doesn't currently make this explicit. Perhaps on the AWS readme page there should be an additional bullet "create an instance" which links to this python code.
In order utilize the python script "AWS EC2" I downloaded the "AWS" code via "Download ZIP" to my local drive. I launched "AWS EC2" via a Jupyter notebook. I ran the first code segment, which is:
import boto3 import os session = boto3.Session(profile_name='blockchain-nodes') ec2 = session.resource('ec2')This produced error, presumably because the credentials file was not found:
